Seoul semiconductor displays luminous efficiency of 84lm/W for lighting with white LED

Seoul semiconductor developed by the brightest white light emitting diode 350mA current maximum beam of 98lm industry, and was exhibited in the "CEATEC JAPAN 2006". Luminous efficiency achieved by 84lm/W, intended for use in lighting equipment. It is reported that the first batch of production will be started before the end of 2006, the latest will not be late in the first quarter of 2007. First put into operation will be the input current of 350mA can be issued when the 65lm beam varieties. White LED is a combination of yellow fluorescent material on the blue LED. Blue LED chip for the United States Cree company's products, the size of about 1mm square. In addition, Seoul semiconductor also exhibited reduced color temperature made of light bulb white LED. When the input current is 350mA, the maximum beam is 67lm, and the luminous efficiency is 57lm/W. The product is expected to be the first before the end of 2006 to start the production of 52lm beam products. In addition, Seoul semiconductor in Cree obtained from the white LED patent licensing, but also to ensure a stable supply of blue LED chips.
