LED biggest feature is: no warm light time (idling time), fast response (about 10 ^ -9 seconds), MR16 small size, power consumption province, low pollution, and suitable for mass production, high reliability, easy to tie the needs of applications made little or array elements, the scope is quite broad, such as automotive, telecommunications industry, computers, traffic lights, the LCD panel backlight, LED screens.
LED industry can mainly be divided into upper, middle and lower categories. Upstream is a single chip and its extension, the LED chip processing midstream and downstream packaging and testing, and application. Among them, the upstream and midstream high technology content, capital investment density. From upstream to downstream, the product is quite different in appearance. LED color and brightness determined by the epitaxial material and epitaxial LED LED Flexi manufacturing costs accounted for about 70% of the LED industry is extremely important.
