1, Cree
CREE, a famous LED chip manufacturer in America, is based on silicon carbide (SiC), gallium nitride (GaN), silicon (Si) and related compounds, including blue, green and ultraviolet light emitting diodes (LEDs), near-ultraviolet lasers, radio frequency (RF) and microwave devices, power switching devices and silicon carbide (SiC) epitaxial wafers suitable for production and scientific research.
2. Osram
Osram is the second largest optoelectronic semiconductor manufacturer in the world, and its products include lighting, sensors and image processors. Headquartered in Germany, the company has R&D and manufacturing bases in Malaysia, with about 3,400 employees and sales of 4.59 billion euros in 2004.
Osram's most famous product is LED, which is only a few millimeters long, with many colors, low power consumption and long life.
3. Riya
Nichia Chemical, a famous LED chip manufacturer and Japanese company, was founded in 1956, and developed the world's first blue LED( 1993) and the world's first pure green LED( 1995), with subsidiaries all over the world.
4. Akio Toyoda
ToyodaGosei Toyota Synthetic, headquartered in Aichi Prefecture, Japan, produces auto parts and LEDs, accounting for about 10% of its revenue.
The white LED jointly developed by Toyota Synthetic and Toshiba is a combination of ultraviolet LED and phosphor, which is different from the combination of blue LED and phosphor.
5. Agilent
As the world's leading LED supplier, its products provide efficient and reliable light sources for many products, such as automobiles, electronic information boards and traffic lights, industrial equipment, mobile phones and consumer products. The high reliability of these components usually ensures that the light source does not need to be replaced during the service life of the equipment. Agilent's low-cost dot matrix LED displays, a wide range of seven-segment code displays and Agilent LED light bar series products come in a variety of packages and colors.
6. Toshiba
Toshiba Semiconductor is the main supplier of automotive LED, especially for dashboard backlight, car radio, navigation system, climate control and other units. The technology used is InGaAlP, and the wavelength range is from 560nm (pure green) to 630nm (red). Recently, Toshiba has developed a new technology, UV+ phosphor. The LED chip can emit ultraviolet rays, and after exciting the phosphor, it can emit all kinds of light, such as white light, pink light, blue-green light and so on.
7、LUMILEDS
LumiledsLighting is a global leader in high-power LED and solid-state lighting, and its products are widely used in lighting, television, traffic signals and general lighting. LuxeonPowerLightSources is its patented product, which combines the characteristics of small size and long life of traditional lamps and LEDs. We also provide various LED chips and LED packages, including red, green, blue, amber and white LEDs.
LumiledsLighting is headquartered in the United States, with factories in the Netherlands, Japan and Malaysia. It was founded by Agilent and Philips on 1999, and Philips completely acquired the company in 2005.
8、SSC
Seoul Semiconductor is the largest manufacturer of LED environmental protection lighting technology in Korea and one of the eight largest manufacturers in the world (source: StrategiesUnlimited-LED Market Research Company).
Seoul Semiconductor's main business is to produce full-line LED assembly and customized module products, including semiconductor light source products driven by alternating current, such as Acriche, side light LED, top light LED, chip LED, plug-in LED and piranha LED. Products have been widely used in general lighting, display lighting, cell phone backlight, TV, notebook computer, car lighting, household goods and traffic lights.
