Showa electrician will launch 500mcd green LED

Onquest upcoming luminescence wavelength of 520nm, 500mcd and 505nm, the wavelength of the light brightness brightness 400mcd green light emitting diode (LED). Compared with the general market sales of green LED, brightness reached about 1.5 times. The above data are obtained under 20mA drive current. Life is introduced for 40 thousand ~ 50 thousand hours. It will be the company's first launch of the light-emitting layer using InGaN's green LED chip. Samples are now available, as long as the order, you can mass production.

The green LED chip in the crystallization of the growth of Showa electrician in its blue chip LED technology used in the "Seeding Process method (SP method)". The so-called SP method, that is to maintain the temperature above 1100 degrees Celsius, the epitaxial growth of crystals. The common method in order to form a low temperature buffer layer, are the first time the temperature down, and then heating up. In addition, in order to improve the efficiency of light irradiation, the electrode structure was improved.
