Taiwan LED lighting exhibitions: emphasis on efficiency and sapphire LED the factory debate
From Taiwan LED lighting exhibition LED the manufacturers product development trend, upstream LED to the high efficiency, high play color sex, high thermal conductivity, improve light uniformity development direction.
Recent crystal electricity main products for HV, LED by three different previously structure blu-ray and 1 star of red chips, 2011 show products by two blue light is red and 2 chip to compose, at present the luminous efficiency has reached 120 lm/W, and application in the LED lights, the highest brightness gun products for 1100 lumens, is by 12 B (blue LED chips) and 12 R (red LED chip) composition, main replace ChuanLiu 75 W light bulbs.
A factory of the ladies circles show LED products, such as HV leds, tungsten copper substrate ChuiZhiXing LED, light distribution of BaiGuangJing evenly. Among them, the new BaiGuangJing piece of main practice is in LED chip directly above the fluorescent powder coating, a few coated in the packaging layer, good for the white light distribution even, dark with the small area more products.
The past in LED after the encapsulation, need to be points the action of Bin, the main reason is that LED process, brightness, wavelength, and colour difference. To improve the components were LED complexity, so Philips Lumileds launch "Freedom"-Binning LED components. In short, according to different brightness or wavelength chips, to match different fluorescent powder production LED components, in order to achieve the customer the standard or color a point-by-point coordinate values.
Note the with the capacity expansion, MOCVD, LED chip factory sapphire substrates of high demand, so in the meeting also see Korea, Russia, AsTek STC factory factory Monocrystal!!!!! To come to the show, the products cover 2 "to 8" crystal rod.
