solar street light manufacturers and high power led

2010 the global LED production value (about ten billion U.S. dollars) to recover almost nearly the TSMC year sales. Many of the large companies will jump into this light sea. The mainland's foregone layout so that in 2012 the traditional LED battle (Armageddon), and the final victory will be China. China has not only mastered the market, the layout of almost one thousand MOCVD machine the sea, so you can seize the LED lights, in the downstream industries.

The vertical LED production necessary for the soldering of the GaN semiconductor substrate of low inflation, but the chosen low expansion material (such as silicon or GuW of) its poor heat dissipation, thermal expansion of the high thermal conductivity material is much larger than GaN (about 5.5 ppm / mK), the LED experts can not find the ideal convergence materials. This DLC for the interface of diamond and copper composite (diamond heat sink) for the substrate produced the world's most advanced perpendicular to the LED. This will allow Taiwan's LED industry to leapfrog ahead of foreign leading companies (such as Nichia, Osram, Lumiled) have taken advantage of to get rid of the patent blockade of Europe, the United States, Japan, Taiwan.

2010 LED tube is used extensively for indoor lighting, outdoor lights and TV backlight. The common incandescent indoor lighting (Incandescent Lamp) and fluorescent (Fluorescent Lamp) is caused by the LCD backlight cold cathode tube (Cold Cathode Fluorescent Lamp) is rapidly be eliminated.

Mainstream LED white lighting, most of the white light are presented in the blue light LED excitation yellow phosphors to generate pseudo-white. The bulk production of the LED are based on a sapphire substrate epitaxial epitaxy growth of GaN LED chip. Growth for the MOCVD (Metal Organic Chemical Vapor Deposition MOCVD). Taiwan has a maximum of MOCVD equipment, first in the country for the World LED die production. But the mainland has to catch up, and even provide the incentives of each the MOCVD grant ten million yuan.

Taiwan, although manufacturing Kingdom for the LED, but like the rest of the foundry industry, LED patent subject to the foreign companies, and each year have to pay large sums of royalties. Money and manufacturing in Taiwan for a foreign boss to make money, but now the production of LED technology has a large number of the relocation of the mainland, which is Taiwan's LED foundry ecology of sorrow.
