Currently, the semiconductor AC LED light industry has formed three pillars, which are United States, Asia and Europe, this competitive landscape will last very long time. For example, the brand of Cree and Lumileds in the United States, Nichia and Toyoda Gosei are the brand of Japan, Osram, which is part of Germany’s Siemens, these kinds of high-end branded products nearly monopolize the LED market.

The five companies have different characteristics in terms of products and markets, Nichia and Toyoda Gosei occupy important position in the AC LED light development history, forming a complete LED industrial chain. Nichia made the first production of the Blue-ray chip in 1994, and it has monopolistic advantages in the patented technology.

Both Cree and GELCore also have their own mature technology system, which focused on the epitaxial industrial chain and chip preparation. Lumileds focus on the research and development of high-power LED, and especially it is very strong in the field of white lighting.

The new entrants of AC LED light industry are making great progress in production capacity and technical capability. For example, besides Japan, United States and Europe, China has become a major producer of white LED. Such as part of the companies in China have developed high brightness blue LED chip, even the product output capacity and quality are not inferior to the brand LED manufacturers.
