The lighting market will once again be in a weak period, and the tariff increase will become a “culprit”?

The lighting market is weak, and the European filament lamp market is highly competitive.

From the first quarter to the second quarter of this year, the price of LED packaging products continued to decrease. In June, the prices of mainstream packaging products in the Chinese market remained stable, but the demand for lighting market remained unchanged. Due to the weak lighting and backlight market, most of the manufacturers are transforming into niche-type and high-tech threshold markets. The car and special lighting market is the new blue ocean.

According to LEDinside statistics, in June, the average retail price of LED bulbs replacing 40W incandescent lamps fell slightly by 0.1% to US$6.3; the average retail price of LED bulbs replacing 60W incandescent lamps dropped slightly by 0.6% to US$7.5.

The market for filament lamps in Europe is highly competitive. In Germany, the average price of LED bulbs replacing 40W and 60W incandescent lamps fell by 0.5% and 3.4% respectively. Brand manufacturers including OSRAM, Philips, Sylvania, Müller, etc., in order to increase market share, low-cost sales of filament lamps, resulting in product prices The decline is larger.

The Sino-US trade war is escalating again, “wrong” LED industry?

On July 10th, the Trump administration promoted the plan to impose tariffs on China’s $200 billion in goods and released a list of target products.

The first round of taxation projects for industrial intermediates has limited impact. In 2017, China’s exports to the United States were about 175 million US dollars. Therefore, the impact on China’s LED industry is quite limited. The main impact is that CREE has lighting factories in the United States. American manufacturer of LEDs from China.

The second round of 200 billion LED products covered a wide range of products, including LED and lighting categories of more than 10 items, and the trade volume is also large, of which the main lighting products in 2017 China exports to the United States The amount is as high as more than 5 billion US dollars.

Because the United States has always been an important export market for China’s LED downstream including lighting and other industries, if the 200 billion US dollar tariff project is approved, China’s LED-related industries will inevitably suffer.

However, due to the obvious advantages of China’s lighting industry, it has formed a global industrial cluster. Compared with other regions in the world, it has obvious comprehensive cost advantages. Therefore, more than 85% of global LED lighting products are assembled and produced in China.

Even with a tariff of more than 10%, it is difficult for US consumers to obtain alternative products from other regions in the short term, and 10% of the additional tariff costs will be shared between US consumers and Chinese lighting manufacturers.


Healthy Lighting LED Lighting Selection Guide

The choice of lighting for the eye health is very straightforward. Before discussing how to achieve different lighting for different functions, we must first understand the relevant knowledge of the lamps and lanterns important parameters in order to be able to buy a satisfactory “eye protection “product.

1. Color temperature. Color temperature directly affects the “color” of the light seen by the naked eye. Work areas often require high color temperature lighting to ensure efficiency and accuracy during work. In rest areas such as bedrooms, high color temperature lighting should not be used to prevent mental stress and excessive stress.

2. Color quality. Color quality is another important indicator. Poor color quality will reduce the visual acuity and the accuracy of the objects being illuminated. Usually the color rendering index of 80 or more is appropriate, there are special requirements can also be increased as appropriate, taking the Bulls love eye LED reading lamp as an example, the color rendering index of 95 or more, to meet the daily reading and even painting requirements. Experts emphasize that low color rendering lights will affect people’s mood and appetite to a large extent, and that things are not realistic, things deviate from their original colors, and they are more likely to cause visual fatigue. By using luminaires with excellent color rendering capabilities, space and color differentiation can be enhanced.

3. Anti-Blu-ray, anti-strobe and other technologies These technologies can protect the eyes from unfair lighting damage. Taking anti-blue light as an example, in accordance with national standards, the risk of blue light to the retina is divided into four levels: non-hazardous, type 1 hazardous (low risk), type 2 dangerous, and type 3 dangerous (high risk) . High-risk lighting can cause irreversible damage to the eyes in a matter of seconds. When purchasing lighting products, pay attention to the safety signs on the product packaging. If there is a CQC certification and approval, it reflects that the table lamp blue light hazard level meets the technical specifications of the non-hazardous category (RG0).

4. Light uniformity In non-local light lighting, we should pay attention to whether the product is designed to prevent concentrated light, such as bull’s eye LED light 100 degree astigmatic light design, diffusion plate, etc., light evenly dark area, also Can play a good anti-glare effect. At the same time, it is recommended to select lighting products with a matte cover as much as possible to prevent eye discomfort caused by direct observation of light sources at close range.

5. Noise Many low-cost lamps often have more obvious noise, especially at night. In fact, current noise or vibration noise not only affects the experience of use, but also can make people feel tired. It is an indicator that is often overlooked by people.

According to experts, just like many home appliances, the quality of lamps and lanterns is often reflected in their technical standards and performance parameters. When purchasing a healthy lighting product, you may wish to pay more attention to the labeling on the product packaging or instructions, and let the product “use data to speak”.

The world’s top five smart cities have been ranked and the city is ranked first.

    5.Los Angeles

Los Angeles has a plan to replace old sodium vapor street lamps with smart LED lamps and plan to replace 200,000 street lamps, and the project is nearing completion. The project has saved the city more than $9 million and reduced the crime rate.

The existing street light poles are being replaced by “smart rods” equipped with 4G LTE wireless technology, which can improve mobile phone signals. Intelligent street lights can also alert the city authorities which luminaires have failed and need repairs, and can monitor and collect information on traffic conditions and parking spaces.


Singapore’s goal is to become the world’s first “smart nation”. Sensors and cameras are being installed to track almost everything from traffic to waste bin capacity.

In Singapore, lighting plays an important role in the intelligent transportation network that uses road sensors, intelligent traffic lights and smart parking.

Prior to this, Philips Lighting and the Sentosa Development Bureau signed an agreement to develop a networked street light management system for Sentosa Island. In addition, the Singaporean government has partnered with UK-based Li-Fi company pureLifi to introduce Li-Fi.


Copenhagen is one of the most sustainable and intelligent cities in the world. Its goal is to achieve carbon neutrality by 2025. Nearly half of the city’s street lights were replaced by LEDs. Many of these new fixtures have become the backbone of an ever-evolving intelligent lighting network.

When the vehicle passes through, the LED street light will turn on and then dim, ensuring that the lights will not be constantly on when it is not necessary. Sensor-loaded luminaires also capture data and analysis and can coordinate the city’s services. For example, luminaires can remind municipal authorities to empty the trash.

2.San Francisco

San Francisco has more LEED-certified buildings than other American cities, and the Connected Cities initiative allows residents to find parking spaces. Recently, San Francisco announced that 18,500 low-pressure sodium lamps will be replaced by smart LEDs.

The new LED will run through a wireless intelligent controller, allowing the city to remotely monitor the performance of a single lamp and adjust the light intensity as needed. For example, if there is a road accident, the lights may light up.

When the lamp is broken or burned out, the lamp will remind the municipal authorities to create a better life for the residents and save the city’s funds.

San Francisco’s new streetlight will be powered by 100% clean energy and, together with wireless control, will become the most environmentally friendly streetlight in California.


Barcelona’s boxes on street lamps contain well-tuned computer systems that measure traffic conditions, road pollution, crowds, and even the number of photos posted on Instagram on specific streets. Sensors installed on street lights and on the ground are also used to monitor the weather in Barcelona.

Barcelona also developed the Sentilo sensor platform as an open source, which means that city planners around the world can study Barcelona’s smart city case and will refer to it.

Smart city lighting has received more and more attention, especially with the increase in industry concentration, LED lighting industry reshuffle has entered a new stage, and China has always attached importance to the development of smart city lighting. Some industry insiders predict that during the “13th Five-Year Plan” period, the output value of smart cities will exceed 700 billion yuan. With the rapid development of the Internet of Things, it is expected that in the “13th Five-Year Plan” period, the output value of smart cities will exceed 4 trillion yuan. If we consider other upstream and downstream industrial chains, such as information technology and data analysis, the entire market scale is expected to expand to the trillion-dollar level.

Intelligent lighting is an indispensable part of a smart city. The huge market potential naturally makes the smart lighting market an unanimously recognized development direction in the industry.

With the support of policies, the hardware infrastructure for the current smart city construction is basically complete. It is understood that in 2017 China Telecom will use 800M low-frequency, wide-area to achieve Internet of Things NB-IoT coverage. It is expected that by the end of June this year, 800M-based NB-IoT network coverage will be achieved, and the coverage of urban infrastructure network will increase significantly. At the same time, operators, network companies, and equipment vendors have jointly formed the application foundation of the Internet of Things platform. In 2017, China Telecom will launch a new connection platform and service platform to provide more intelligent connectivity and empowerment capabilities to meet the needs of smart cities, a variety of application scenarios for connection and application development.

How to develop LED smart street lights? Philips Lighting thinks so

As early as February 2014, Philips and the communications company Ericsson reached a cooperation, jointly launched the launch of 4G smart street lights. Ericsson improved the performance of mobile networks by placing mobile telecommunications equipment in the Philips networked LED street light poles.

Subsequently, Philips entered into a partnership with ABB, a building automation supplier, in March. Philips’ interconnected lighting system seamlessly interfaces with ABB’s automation software to control commercial environments such as lighting, curtains, access control, heating, ventilation and air conditioning systems. This pioneering cooperation has made important contributions to reducing the cost of rebuilding small and medium-sized commercial buildings. For example, for a hotel, if you need to integrate several separate rooms into one large meeting room, you can change the lighting scene with one click.

In September 2016, Philips Lighting and Huawei Technologies signed a cooperation agreement to ensure seamless connection between the Philips Hue Home Intelligent Lighting System and the Huawei OceanConnect Internet of Things (IoT) Platform. According to the agreement, Huawei became a Friends of Hue partner of Philips.

In November 2016, Philips Lighting and Xiaomi formed a new joint venture company to design and develop smart connected LED lighting products for the Xiaomi Smart Home Ecosystem, enabling application (App) pairing in Android (Android) and iOS (iOS) smartphones. Intelligent lighting control.

In March 2017, Philips Lighting announced the launch of the Location Lab Partner Program, which will promote cooperation between Philips Lighting and various types of indoor positioning companies to explore innovative applications using Philips Indoor Positioning System to meet retail stores, New demands for shopping centers, offices and other formats.

In April 2018, Philips announced TrueForce LED street light sources to accelerate the conversion of traditional street light sources to high-efficiency LEDs. The Philips TureForce LED is Philips Lighting’s first in-situ replacement LED street light source for traditional high-pressure sodium lamps. By replacing the innovative LED product, LED lighting of the street light source can be upgraded without replacing the existing floodlight.

On May 22, 2018, in order to help LED companies understand the development trend of smart street lamps, Huang Feng, director of Philips Lighting (China) Co., Ltd., will attend the 2018′ LED auto lighting and lighting at Shanghai Shenwang Hotel. Smart Street Lighting Technology Symposium, he will deliver a keynote speech on the scene of LED smart street lamps, and discuss the latest technological progress of smart street lamps with the participating engineers.

At present, the replacement of LED intelligent street lamps has begun in many places in China. These intelligent street lamps not only can realize the role of lighting, but also integrate photovoltaic new energy, IOT charging piles, environmental sensors, and intelligent monitoring equipment into one, and can collect energy. Charging, monitoring of traffic conditions, voice alarms, wireless network signal (WiFi) transmission, public broadcasting, and air, noise, road water monitoring and other functions.

With the increasing number of additional functions, the number of technologies that need to be combined increases, and the added value of LED intelligent street lamps will be even higher. Dr. Huang Feng pointed out that the key elements of smart road lighting are connection technology, installation interfaces and service platforms, and future in-kind materials. Under the background of the development of networking, the industry needs to grasp the trend of full connectivity of the Internet of Things, big data analysis, and service innovation, and actively promote the development of smart lighting to scalable services.

It is understood that Dr. Huang Feng is a senior expert and professor-level senior engineer responsible for the strategic planning and innovation of intelligent lighting standards. He served as the vice chairperson of the Intelligent Building Technology Committee of the Building Energy Efficiency Association, the National Intelligence Standards Committee (TC426), the China Lighting Association Standards Committee (CALIS), and the China Semiconductor Lighting Alliance (CSA). He took the lead in the drafting of a number of international, national and industrial communications and lighting standards, holds a number of international invention patents and won the National Technology Progress Award.
In addition, Dabit Information, which focuses on vertical segmentation conferences, will gather decision-making management and R&D personnel from LED street lighting, drive module power supplies, wireless/light controllers, and intelligent gateways on May 22 to jointly discuss technologies. Among them, Prof. Yan Zhongguang of Shanghai Microelectronics also attended this meeting as a special guest.

The conference speech topics will also include car lighting drive program, LED car lighting dimming program, LED car lighting intelligent control, automotive lighting test and circuit protection, smart street lamp wireless charging technology, intelligent street lamp market development prospects, LED intelligent street lighting control Technology, LED light source chip technology and other hot spots, welcomed the LED street lamp lighting, drive module power supply, wireless / lighting controllers, intelligent gateways, and other manufacturers of decision-making management and R & D personnel to conduct technical discussions together.

Global intelligent lighting enters the high-speed development stage, lighting manufacturers seek transformation.

The Hong Kong International Spring Lighting Fair, hosted by the Hong Kong Trade Development Council, was opened at the Hong Kong Convention and Exhibition Centre on April 6. The four-day exhibition (April 6th to April 9th) brought together more than 1300 companies from nearly 20 countries and regions. The show presented a spectacular feast of lighting products and the latest technology to the visitors.

“Celebrity Lighting Gallery” continues to be the highlight of the lighting show, presenting more than 200 brands, including graffiti intelligence, Mulinsen, TCL Lighting and TE-Connectivity, to showcase a wide variety of lighting products and technologies with exceptional design and functionality. The new “Smart Lighting and Lighting Solutions” exhibition area opened last year was also re-visited to showcase a variety of new smart lighting systems, remote controls, accessories and lamps.

Smart lighting will undoubtedly become the most eye-catching product in all kinds of lighting products. The term “smart lighting” is not unfamiliar to the industry, but the actual use of LED lighting products is not long.

Since 2016, many well-known lighting companies in China, such as NVC Lighting and Mulinsen, have begun to turn to build high-end, intelligent product platforms. The AIoT (artificial intelligence + Internet of Things), which provides smart solutions for traditional lighting companies Platform-based companies are also taking advantage of this trend, and cross-border companies such as Haier are also seeking new opportunities for cooperation. In 2017, with the continuous improvement of intelligent lighting technology, the ecology of the industrial chain, and the active promotion of manufacturers, the global intelligent lighting market has entered a period of rapid development.

Due to the continuous development of the era and technology, users have higher and higher requirements for the experience of lighting products, and intelligent lighting is everywhere humanized. Coinciding with industrial upgrading and supply-side reforms at the national level, it is also a powerful guarantee and backing for the development of smart lighting.

Intelligent lighting also facilitates centralized control and management, which facilitates cost control and optimization. In large-scale lighting systems, such as street lighting and building lighting, smart lights can automatically adjust the light brightness according to the sky color changes, and can also automatically detect whether the loop is operating normally, and transmit information back to the information center through the network in real time, and can also consume power every day. The quantity is counted out so that the manager can optimize the cost control.

In addition, intelligent lighting also has the advantages of energy saving, convenience, and easy control. The rise of the Internet of Things also allows companies to introduce the necessity of networked lighting. Therefore, in the commercial and industrial lighting market, the demand for intelligent lighting has grown rapidly. Under the digital development, intelligent lighting will bring more new business models and value enhancement to these two fields, and will gradually replace traditional lighting and become mainstream products.

At this stage, industrial and commercial accounts for 60% of the total scale of smart lighting, and home smart lighting is still in its infancy, but it has the fastest growth rate.

At present, the global smart lighting market still needs to rely on the continued expansion of public infrastructure, and the biggest promoter is the construction of smart cities and smart buildings. Thanks to government support, major cities in the world are pushing for smart city plans and the application of smart lighting in the public sector will continue to be given priority.

In recent years, the state has vigorously advocated the policy orientation of low-carbon and environmental protection. The urban lighting project has also started from various aspects such as program design, light source selection, and material selection, reducing the use cost, and achieving the effect of energy saving and power saving. In recent years, with the vigorous development of urban lighting projects, smart lighting has gradually entered the public view. The typical usage scenario is “intelligent buildings”, which can achieve precise operation, which means which is bright, and energy-efficient.

Intelligent lighting has the advantages of energy saving, convenience, and easy control. The rise of the Internet of Things also allows companies to introduce the necessity of networked lighting. Therefore, in the commercial and industrial lighting market, the demand for intelligent lighting has grown rapidly. Data shows that in 2017, industrial and commercial lighting accounted for 60% of the global smart lighting market. Under the digital development, intelligent lighting will bring more new business models and value enhancements to these two fields.

In contrast, although the actual number of households adopting intelligent lighting is still a small number, the application of smart home lighting will gradually become more common as consumers’ living standards improve, relevant policies are promoted (supply-side structural reforms) and the promotion of manufacturers. .

The relevant agencies estimate that residential lighting will account for 23% of the global smart lighting market in 2017, and will increase to 31% in 2020. In the next few years, smart lighting and smart home will develop in parallel and will become the fastest growing application areas.

In recent years, global lighting manufacturers have adopted different strategies to accelerate the transformation and upgrading, and successively gave up general-purpose lighting with low profits, and attacked smart lighting with higher profits and better prospects.

At present, lighting manufacturers that have transformed abroad faster include Philips Lighting, OSRAM, Cree, GE, LEDVANCE, LIFX, and Acuity Brands. Domestic manufacturers such as Foshan Lighting, Jiajie Xinyuan, Huaiju Lighting, Kaiyao Lighting and other companies have achieved interconnection and interoperability between lighting products and remote control of smart terminals through their own R&D and cross-border cooperation.

Although smart lighting will spread to every corner in the future, its market prospects are immeasurable. However, there are still some problems at this stage.

The communication protocol is torn: The adoption of private communication protocols by different lighting companies is one of the obstacles to the development of smart lighting. At present, there are various communication protocols on the market, which cause the platforms provided by various manufacturers to be unable to interconnect and interoperate, which causes great difficulties for the development of the intelligent lighting industry.

The threshold for transformation is high: Traditional lighting companies want to implement smart product upgrades, but also face many problems such as long development cycle, high cost, difficulty, incompatibility, and failure to globalize. From product concept design to final mass production, it usually takes half a year to a year to allow companies to respond to market demands and competition in a timely manner. The large amount of manpower and capital investment has moved millions, and high-cost investment has increased the company’s business risks.

Inadequate intelligence: Most of the current smart lighting is not really “intelligent”, but also simply dimming. Scenery, automation, linkage with other smart devices can be called true smart lighting.

The lighting system in a smart city is too large to be completed by a single lighting company alone. It needs a platform-based AIoT (artificial intelligence + internet of things) company that can integrate upstream and downstream resources to coordinate the overall industry and lead the way with home appliances including lighting companies. It is the best solution and the future trend for manufacturers to join forces and enter the market of smart lighting, smart homes and smart cities.

Global light bulb prices were released in March! Filament lamps are still popular in the European market.

According to the LEDinside latest price report, the price of power 3030 LED package products in the Chinese market was significantly reduced in March 2018, and the price of high-power ceramic substrate LED package products was slightly reduced. Other products The price remained stable.

Wang Ting, an analyst at LEDinside, said that in March, the price of the largest 1000mA high-power ceramic substrate LED package products continued to show a slight decrease of 0.8%; in the mid-power product segment, along with the new listing and various manufacturers to increase promotion, 3030 The average price of LEDs decreased by 5.2%. In terms of new products, manufacturers continue to improve product performance. For example, Nissan introduced ultra-high CRI medium power 3030 new Optisolis, Ra 95 above, R9 reached 80 or more, and there is no UV radiation. This product is suitable for museums and art galleries lighting and other high-CRI, but also need to avoid UV radiation, or retail lighting and other fields.

In terms of global LED bulbs, prices remained stable in March 2018. The average retail price of LED bulbs replacing 40-watt incandescent bulbs rose slightly by 1% to US$6.4; the average retail price of LED bulbs replacing 60-watt incandescent bulbs rose by 0.6% to US$7.6.

From the regional perspective, filament lamps are still relatively popular in the European market, and most of the new products recently launched by manufacturers are filament lamps. In place of the 40-watt segment, prices in the UK rose by 1.7% in March. OSRAM launched three new products, including two filament lamps. In other regions, the average price increases in Germany, the United States, and Japan were both around 1%, while prices in South Korea, China, and Taiwan were stable.

In place of the 60-watt segment, prices in China fell by 1.7%. In addition to the effects of exchange rates, the prices of some manufacturers’ products also declined. Such as Philips 9.5W 800lm bulbs, the price fell to 4.69 US dollars, a decline of more than 30%. In other regions, prices in Germany, the United States, and Japan rose by 1%-2%, while prices in the United Kingdom, South Korea, and China Taiwan remained stable.

According to relevant statistics, in 2015, the global LED filament lamp market demand has reached more than 70 million, an increase of 376%. In 2017, the total market capacity of LED filament lamps will reach 4-5 billion. The global LED filament lamp market in 2017 is expected to reach 5.66 billion yuan (approximately US$831 million), an increase of 95% year-on-year; CAGR will reach 47.7% from 2017 to 2022. It is estimated that by 2020, the global market size of filament lamps will reach 20 billion U.S. dollars.

A large number of market demands have attracted the layout of many companies, with the exception of Philips, Osram, GE and other international companies, domestic Foshan Lighting, Shanghai Yaming, Yapuer, Hongli Optoelectronics, Hangke Optoelectronics, Mulinsen, Boshi Lions, Stars Gao Hong LED lighting factories or packaging companies, such as source Lei technology have also entered the field of LED filament lamps and increase production. According to relevant media reports, there are currently more than 800 companies involved in the production of LED filament lamps in China.

Leveraging LED lighting, scientists successfully planted vegetables in Antarctica.

Scientists at the Neumayer Station III in Antarctica at the outdoor temperature below -20°C successfully planted soils, sunlight and sunlight in the high-tech greenhouse (EDEN-ISS). Pesticide vegetables include 3.6 kilogram salad lettuce, 18 cucumbers, and 70 radishes.

It is understood that scientists use water-based cultivation methods to use reusable water circulation and nutrient systems, while replacing sunlight with LED lighting and carefully monitoring indoor carbon dioxide.

In addition, according to the German Aviation Center, by May, scientists are expected to harvest 4.5 kilograms of fruits and vegetables a week.

It is reported that this was not the first attempt. As early as 2015, NASA had successfully planted vegetables on the International Space Station.

However, it is worth noting that the project focuses on the more versatile vegetable varieties such as radish, salad greens, tomatoes, cucumbers, peppers, and even herbs in the future to Mars or the moon.

However, such planting systems also have their limitations. Scientists say that some fruits and vegetables have to wait for a long time to mature, such as strawberries, and they are still waiting for a successful harvest.

The gap between Chinese enterprises and transnational giants is still

The LED lighting industry is welcoming new opportunities such as smart lighting and optical communications, but European giants such as Philips and Siemens are fading out.

Philips and Siemens are the oldest lamp manufacturers in Europe. Their lamp business has a history of more than 100 years. Lighting was one of their leading businesses. Philips became one of the largest carbon filament lamp manufacturers in Europe in the late 19th and early 20th centuries. In 1919, Siemens and the other two companies jointly established OSRAM Bulbs.

In the era of incandescent lamps, European and American companies such as Philips, Osram, GE, etc., were all-powerful. However, with the popularization of LED lighting, the technical route has been completely transformed, and the traditional patent giants’ technology patent barriers have collapsed. Asian companies, including Chinese companies, have rapidly emerged with their industrial chain and cost advantages. The revenue growth of Philips and OSRAM’s lighting business decreased, and profits became thin.

Seeing the intense competition in the consumer electronics field, Siemens and Philips began a strategic transformation a few years ago. In 2014, Siemens released its 2020 vision for the company and will focus on electrification, automation and digitization in the future. Philips continues to drive the transformation of the company into a leader in the field of health technology.

Since the lighting business accounted for a relatively small portion of their overall profits, they chose to make the lighting business “single flight.” In July 2013, Siemens split OSRAM to go public. In the second half of 2014, Philips merged the LED chips with the Automotive Lighting Division and established it as an independent subsidiary. The new company was named Lumileds.

The “independent” Philips and Osram lighting businesses have become the targets pursued by Chinese companies. In 2015, Philips had planned to sell 80.1% of Lumileds’ shares to the Chinese consortium, which was later terminated by the US Foreign Investment Commission’s block. In May 2016, Philips spin-off Philips Lighting was separately listed.

In July 2016, OSRAM sold its LEDVANCE company responsible for the lighting business to Mullinson and its strategic partners. At the end of 2017, China’s LED chip leader Sanan Optoelectronics and a Chinese-funded conglomerate with a background in Jinsha River Venture Capital would like to take over the 17.34% stake in Osram Lighting held by Siemens, but German economic ministers have expressed their opposition.

“Chinese companies are taking the path of internationalization. In the future, the competition in the overseas market will be unavoidable with Philips and OSRAM.” Zhang Hongbiao, a senior analyst in the LED lighting industry, believes.

All these factors have led to the optimistic expectations of the lighting industry, “retreat into China”.

In fact, Siemens, Philips fade out of the lighting industry, does not mean that Osram, Philips Lighting has no future. On the contrary, after their “single flight”, they are speeding up the deployment of emerging fields such as smart lighting and optical communications. OSRAM announced its LED, laser and photo-electric sensing solutions with autopilot at 2018CES, and is one of the leading suppliers of iris-unlocking related sensors for smartphones. Philips Lighting announced the smart lighting IoT platform at the Lighting Fair in Frankfurt, Germany, last week. For the first time, it exhibited the Visible Light Communication (LiFi) technology, which can transmit multiple high-definition movies while making video calls.

Light, formerly used only for lighting, can be used for wireless communication in the future, sensing distance, applied to intelligent driving, and information transmission, becoming an entrance to smart cities, and even used to cultivate crops and adjust patient moods. Therefore, after diluting the traditional lighting business and entrusting more LED lighting business to Chinese companies, OSRAM and Philips Lighting, which will soon be renamed Signify, are all exploring the future of light, exploiting the high levels of LED chips and LED lighting. In the field of value, it provides a full range of service solutions for smart lighting.

From the perspective of scale, after “Solofly”, Philips Lighting generated revenue of Euro 6.965 billion in 2017. Osram’s revenue for fiscal year 2017 was 4 billion Euros, which is an annual revenue of 30 billion to 50 billion Yuan. In contrast, the leading companies in China’s lighting industry have grown rapidly, but their body mass is still small. Sanan Optoelectronics, Mulinsen, Op Lighting, NVC Lighting, and Sanxi Aurora are all working toward the goal of 10 billion yuan. Obviously, regardless of revenue, profit scale, brand influence, and technology accumulation, there is still a clear gap between China’s lighting companies and multinational lighting giants.


LED rare earth luminescent material research progress will become a new generation of lighting

Rare earths are used in many areas of China’s photovoltaics. According to reports, research on rare-earth luminescent materials for LEDs has progressed, and phosphors will become a new generation of lighting sources. How about specific conditions? Let’s learn about the rare earth luminescent materials used in LEDs.

LED solid-state lighting devices have the advantages of high efficiency, energy saving, and environmental protection. After more than ten years of development, they have basically replaced traditional incandescent and fluorescent lamps and become a new generation of lighting sources. The phosphor has a wavelength conversion function and plays an important role in determining the white light performance of the LED, such as color rendering index, color temperature, and efficiency. It is one of the key materials for the LED lighting device. The phosphor with high research and development efficiency and good thermal stability has been It is the goal pursued by people.

The optoelectronic functional materials and device team of the Institute of Advanced Manufacturing Technology, Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences, developed a new type of Ba9Lu2Si6O24: Ce3+ silicate blue phosphor; its fluorescence quantum efficiency can be maintained at room temperature at 160°C. 94%, showing good thermal stability. The study was awarded a national invention patent and the relevant results were published on Advanced Optical Materials.

Based on the Ba9Lu2Si6O24 material, the team used a Tb3+-Tb3+ quantum trimming and resonance energy transfer effect to obtain a green phosphor with a luminous efficiency of up to 144%. The visible light quantum trimming was achieved. The anomalous red emission of Eu2+ was observed for the first time. Spectral means traced back to the source of red light; on this basis, a single white light was obtained by co-doping of Ce3+/Eu2+/Mn2+. Obtained one of the national invention patents and related basic research results are published in The Journal of Physical Chemistry C, Materials Research Bulletin.

Recently, the team conducted a systematic study on the luminescent properties of Ba9Lu2Si6O24-based cyan phosphors through a combination of theory and experiments. Through the optimization of the process, the internal quantum efficiency of fluorescence is improved to 90%, and the decay of light within 1600 hours at 85°C/85%RH is less than 10%. Only the cyan fluorescent powder and the red powder are compounded, and white light having a color rendering index of 90 or more can be obtained on the NUV chip. Based on the calculation and understanding of the first-principles electronic structure of Ba9Lu2Si6O24, combined with the experimental characterization of spectroscopy, the team proposed a method to calculate the bandgap of the substrate of a wide band gap inorganic non-metallic material, and revealed the thermal stability mechanism of the material’s luminescence, except The interaction between heat and phonons can cause luminescence quenching, and the decrease in absorption rate due to heat is another cause of thermal quenching of luminescent materials. The relevant results were published in the Journal of Materials Chemistry C.

In addition, the team raised the steady-state fluorescence quantum efficiency of Gd3Al2Ga3O12:Ce3+ yellow afterglow phosphors to 82%, which provides a potentially valuable rare earth luminescent material for solving AC LED stroboflash problems. The related content has applied for 2 national invention patents, and some research results have been published on Chemical Communications.

Mandatory certification! New LED bulbs emerged on June 1st.

Recently, the Australian/New Zealand Bureau of Standards issued AS/NZS4417.2:2012 revised standard for the fourth edition of the Electronic and Electrical Products Compliance Marking Standard A4:2017. This revision expands the list of products under control, reclassifies the security level of some products, and also updates the definition of some products. It is worth noting that this revision will add 6 types of products, including LED bulbs and nightlights, to the scope of compulsory certification products. The standard stipulates that starting from June 1, 2018, products such as LED bulbs and night lights entering the Australian market must first apply for a mandatory safety certificate (SAA certification).

It is reported that SAA Australia International Standards Corporation is Australia’s only standard certification body. Whether imported or assembled in Australia, electrical products must first be certified by Australian International Standards before entering the Australian market. Thanks to the mutual recognition agreement between Australia and New Zealand, all products certified by Australia can successfully enter the market in New Zealand.

There are two main types of SAA signs, one is formal recognition and the other is standard sign. Formal approval is only responsible for the samples, while the standard signs need to be reviewed one by one. The expansion of the scope of Australia’s compulsory safety certification products will greatly increase the production and testing costs of the company. Once the product quality does not meet the standard requirements, being spot checked and reported by the Australian market will cause the company to suffer economic losses.

It is understood that electric light sources and lighting products are key export products in Shaoxing, involving more than 100 export companies, with an annual output value of more than 600 million US dollars. In recent years, Shaoxing exports LED products due to foreign technology trade barriers to return the case gradually increased, the reasons for return related to product certification, energy efficiency identification, origin identification.

In response to this New Zealand-Australia launch of the New Deal, Shaoxing Inspection and Quarantine Bureau reminded relevant lighting manufacturers exporting to Australia: to pay attention to Australia’s revision of the standards for electronic and electrical products, study and study the new standard, and respond well to technical trade measures. We have a few ideas; strengthen product quality self-inspection and self-control, and use good raw materials, production safety and export inspection in quality management, use raw materials and components that meet the standards, and look for professional third-party agencies for testing and certification. According to the standards of the importing country, the company will carry out early detection and check and prepare for the situation before the end of the transitional period.
