Eight LED manufacturers in the world

LED light-emitting diode, is a semiconductor light-emitting solid device, it is the use of solid semiconductor chip as the light emitting material, when the ends with a positive voltage, the semiconductor carrier recombination occurs due to photon emission and generate light. 

At present, large LED Supplier: U.S. lumens Lumileds, USA CREE, Germany and Europe Osram Osram, Nichia of Japan Nichia, Seoul Semiconductors SSC, Taiwan Edison Edison and so on. 

1, CREE (CREE) 

Famous LED chip manufacturers, the United States CREE company, product, silicon carbide (SiC), gallium nitride (GaN), silicon (Si) and related compounds as a base, including blue, green and ultraviolet light-emitting diode (LED), near UV laser, radio frequency (RF) and microwave devices, power switching devices and suitable for the production and research of silicon carbide (SiC) wafers. 

2, OSRAM (Osram) 

OSRAM Opto Semiconductors is the world's second largest manufacturer of lighting products, sensors, and image processor. The company is headquartered in Germany, R & D and manufacturing base in Malaysia, about 3400 employees and 2004 sales of 4.59 billion euros. OSRAM's most famous product is the LED, the length of only a few millimeters, a variety of colors, low power consumption, long life. 

3, NICHIA (Nichia) 

Nichia, the famous LED chip manufacturer, Japanese company, founded in 1956, developed the world's first one blue LED (1993), the world's first one pure green LED (1995), in the rest of the world has a child the company. 

4, Toyoda Gosei (Toyoda Gosei) 

Toyoda Gosei Toyoda Gosei, headquartered in Aichi, Japan, the production of automotive components and LED, 10% LED accounting for income, Toyoda Gosei and Toshiba jointly developed white LED, a UV LED and phosphor combination of the way, the general blue LED and phosphor combination of different ways. 

5, Agilent (Agilent) 

As the world's leading LED supplier of products for the automotive, electronic message boards and traffic signal lights, industrial equipment, consumer products, such as cellular phones and a large number of products to provide efficient and reliable source. High reliability of these components is usually no need to replace the light source can be guaranteed during the life of equipment. Agilent's low-cost dot matrix LED display, a wide variety of seven-segment display and LED light strips Agilent products have a variety of packages and colors to choose from. 

6, TOSHIBA (Toshiba) 

Automotive LED Toshiba Semiconductor is a major supplier, especially dashboard backlighting, car radio, navigation system, climate control unit. Technology uses InGaAlP, wavelengths from 560nm (pure green) to 630nm (red). After recently, Toshiba has developed a new technology UV + phosphor (UV + fluorescence), LED chip emits ultraviolet light to stimulate phosphor to issue various combinations of light, such as white, pink, light green and so on. 

7, LUMILEDS (lumens) 

Lumileds Lighting is the world's high-power LED and solid-state lighting leader, its products are widely used in lighting, television, traffic signals and general lighting, Luxeon Power Light Sources are the patented product, combines traditional lamps and LED's small size, long life characteristics. Also offers a variety of LED chips and LED packaging, red, green, blue, amber, and white LED.Lumileds Lighting is headquartered in the United States, the factory is located in the Netherlands, Japan, Malaysia, the joint venture between Agilent and Philips in 1999, 2005 Philips complete the acquisition of the company. 

8, SSC (Seoul Semiconductor) 

Seoul Semiconductor is South Korea's largest manufacturer of LED lighting technology and environmental protection, and is a global manufacturer of one of the eight (Source: Strategies Unlimited-LED market research firm). Seoul Semiconductor's main business is the production line LED assembly and custom module products, including the use of AC-driven semiconductor light source products, such as: Acriche, edge-lit LED, top light LED, sliced ​​LED, plug-in LED and Piranha (super light) LED and so on. Products have been widely used in general lighting, display lighting, backlighting mobile phone, TV, laptop computers, automotive lighting, household goods and traffic signals among the areas.
