3. NICHIA
Japan Asia Chemical, a famous LED chip manufacturer, is a Japanese company founded in 1956. It developed the world's first blue LED (1993) and the world's first pure green LED (1995). It has subsidiaries all over the world. .
4. Toyoda Gosei
Toyoda Gosei, headquartered in Aichi, Japan, produces automotive parts and LEDs. LEDs account for about 10% of revenue.
Toyoda Gosei and Toshiba The white-light LED jointly developed uses a combination of ultraviolet LED and phosphor, which is different from the general combination of blue LED and phosphor.
5. Agilent
As the world's leading LED supplier, its products are used in numerous products such as automobiles, electronic information boards and traffic lights, industrial equipment, cellular phones and consumer products. The product provides an efficient and reliable light source. The high reliability of these components often ensures that the light source does not need to be replaced during the lifetime of the device. Agilent's low-cost dot matrix LED displays, a wide variety of seven-segment displays and Agilent's LED light strip series products are available in a variety of packages and colors.
6. TOSHIBA
Toshiba Semiconductor is a major supplier of automotive LEDs, especially dashboard backlights, car radios, navigation systems, climate control and other units. The technology used is InGaAlP with wavelengths from 560nm (puregreen) to 630nm (red). Recently, Toshiba has developed a new technology called UV phosphor. The LED chip can emit ultraviolet light, excite the phosphors and then combine them to emit various lights, such as white light, pink, cyan and other lights.
7. LUMILEDS
LumiledsLighting is a global leader in high-power LED and solid lighting. Its products are widely used in lighting, television, traffic signals and general lighting. LuxeonPowerLightSources is its patented product , combines the small size and long life of traditional lamps and LEDs. We also provide various LED chips and LED packages, including red, green, blue, amber, white and other LEDs.
LumiledsLighting is headquartered in the United States, with factories located in the Netherlands, Japan, and Malaysia. It was established in 1999 as a joint venture between Agilent and Philips. In 2005, Philips fully acquired the company.
