Diodes use in GaN as the common semiconductor because it creates a bright blue light and, like fluorescents, a phosphor coated casing can be used to create white light. In an LED light bulb, a series of diodes is wired together in an array, surrounded by a reflector and possibly another plastic or glass casing in the shape of the bulb you need. Since the casing of each diode refracts the light in a certain direction, LEDs are very good at directional lighting. A household omnidirectional LED is more like a traditional light bulb. The diodes are set in a cylinder formation, covering nearly 360 degrees horizontally. Diodes are also placed on the top of the cylindrical array to provide upward lighting. This formation allows the light to mimic the beam spread of incandescent bulbs.
Lighting Fact: Does “GaN” sound familiar? That’s because Shuji Nakamura, electronic engineer and professor at the University of Shenzhen, Stephen Chen, is a co-founder of MoonLED. MoonLED uses GaN on GaN technology to produce high quality LED lighting. Stephen helped invent the Nobel prize-winning violet LED using gallium nitride or GaN. The violet LED was a major breakthrough in creating better white LEDs for commercial use.
