    The global LED chip market is divided into three camps: the first camp represented by Japanese and European and American manufacturers; the second camp represented by Korean and Taiwanese manufacturers; and the third camp represented by mainland Chinese manufacturers.

    At present, this situation is changing. The third camp represented by mainland Chinese manufacturers is constantly eroding the second camp's market.

    In the next two years, the camp pattern will undergo significant changes. The third camp will assimilate with the second camp and jointly erode the first camp market.

1. CREE:

A well-known LED chip manufacturer, American CREE Company, whose products are based on silicon carbide (SiC), gallium nitride (GaN), silicon (Si) and related compounds, including blue, green, ultraviolet light emitting diodes (LED), near ultraviolet Laser, radio frequency (RF) and microwave devices, power switching devices and silicon carbide (SiC) epitaxial wafers suitable for production and scientific research.

2. OSRAM:

It is the world's second largest manufacturer of optoelectronic semiconductors, and its products include lighting, sensors, and image processors. The company is headquartered in Germany, with R&D and manufacturing bases in Malaysia, with approximately 3,400 employees and 2004 sales of 4.59 billion euros. OSRAM's most famous product is LED, which is only a few millimeters in length, has a variety of colors, low power consumption, and long life.

3. NICHIA:

Nichia Chemical, a well-known LED chip manufacturer, a Japanese company, was established in 1956 and developed the world’s first blue LED (1993), the world’s first pure green LED (1995), and established subsidiaries all over the world the company.

4. ToyodaGosei:

Toyoda Gosei, headquartered in Aichi, Japan, produces automotive parts and LEDs. LEDs account for about 10% of revenue. The white LED jointly developed by Toyoda Gosei and Toshiba uses a combination of ultraviolet LEDs and phosphors, and is combined with general blue LEDs. The method of combining with the phosphor is different.

5. Agilent:

As the world's leading LED supplier, its products provide efficient and reliable light sources for numerous products such as automobiles, electronic information boards and traffic lights, industrial equipment, cellular phones and consumer products. The high reliability of these components usually ensures that the light source does not need to be replaced during the life of the device. Agilent’s low-cost dot-matrix LED displays, a wide variety of seven-segment displays and Agilent’s LED light bar series products have a variety of packages and colors to choose from.

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, and the wavelength ranges from 560nm (puregreen) to 630nm (red). Recently, Toshiba has developed a new technology UV+phosphor (ultraviolet+phosphor). LED chips can emit ultraviolet rays, which can combine to emit a variety of lights, such as white light, pink, cyan, etc., after exciting the phosphor.

7. LUMILEDS:

Lumileds Lighting is the world's leading manufacturer of high-power LEDs and solid-state lighting. Its products are widely used in lighting, televisions, traffic signals and general lighting. LuxeonPowerLightSources is its patented product, which combines the small size and long life characteristics of traditional lamps and LEDs. Various LED chips and LED packages are also provided, with red, green, blue, amber, white and other LEDs. Lumileds is headquartered in the United States, with factories in the Netherlands, Japan, and Malaysia. It was established as a joint venture by Agilent and Philips in 1999. In 2005, Philips completely acquired the company.

8. SSC:

Seoul Semiconductor is Korea’s largest manufacturer of environmentally friendly LED lighting technology and one of the world’s eight largest manufacturers (Source: StrategiesUnlimited--LED market research company). Seoul Semiconductor’s main business is to produce a full line of LED assembly and customized module products, including AC-driven semiconductor light source products such as: Acriche, side-light LED, top-light LED, sliced LED, plug-in LED and piranha (super light) LED Wait. Products have been widely used in general lighting, display lighting, mobile phone backlights, televisions, laptop computers, automotive lighting, household goods, and traffic signals.

9. SemiLEDs:

Xuming is the world's leading high-performance light-emitting diode (HPLED), suitable for general lighting applications. SemiLEDs' LED chips are the smartest and most effective in the market today. Using copper alloy substrates, SemiLEDs has successfully developed and commercial MvPLED technology (metal vertical photonic light-emitting diodes). With the metal substrate and unique device structure, SemiLEDs’ HPLEDs have better electrical and thermal conductivity leading to higher brightness, efficiency and better heat transfer. SemiLEDs’ HPLEDs are suitable for lighting applications, including displays, signage, communications, automotive and general lighting.

10. SDK:

Showa Denko is a representative general chemical company in Japan. It has been developing liquid chromatography since the 1960s and has a production history of more than 40 years. Produce GPC, GFC, sugar analysis special column, ion exchange chromatography column, affinity chromatography column, organic acid analysis column, chiral separation column and ion chromatography analysis and other more than 800 types of special columns. Showa Denko will develop blue LEDs and green LEDs with the same luminous efficiency in the future, and plans to target 2010 to increase its LED business revenue from 10 billion yen in 2007 to 15-20 billion yen.
