LED Corn Light

Cheap led corn light

For general lighting, people need a white light source. 1998 white light led corn light open Successful hair. This LED is the GaN chip and yttrium aluminum garnet (YAG) package together. GaN chip emits blue light (P =465nm, Wd=30nm), made of high temperature sintering of Ce3+ containing YAG phosphor by the blue light emitting yellow light emission, peak 550nm. Blue chip installed in the LED based wanxingreflection in the cavity covered with a resin mixed with thin films of YAG, about 200-500nm. The blue light emitted by the LED substrate is absorbed by the phosphor, and another part of the blue light and the yellow light emitted by the phosphor powder can be mixed into a white light. The InGaN/YAG white LED, YAG phosphor by changing the chemical composition of the phosphor layer and adjust the thickness of the 3500-10000K color temperature can be colored white.

Blu ray LED technology, in short, is a more efficient way to produce light, but also can be applied to cameras, mobile phones and other scientific and technological products. The use of blue led corn light technology to create lighting equipment, energy efficiency is higher, greatly reducing the amount of energy used in the earth. According to the existing data show that 25% of the world’s electricity is used for lighting, and the use of LED lamps, lighting for the power down to 4%, and this will undoubtedly change the world.

From the 1907 LED effect found to 1993 Nakamura Shuji formally invented LED, and then to 1W in 1999, the official use of the commercial cheap led corn light, LED has experienced nearly one hundred years of development. Prior to this, people have been using the last century, Edison invented incandescent bulbs, incandescent bulbs and waste most of the energy in the heat, about 90% of the electricity is wasted.

LED lamp, greatly reduce the power needed for lighting, LED lamps of the same wattage, the required power of incandescent bulbs only 1/10, while LED has the advantages of long service life, environmental protection and maintenance free, rapidly replacing incandescent lamp position. In 2012, the Chinese government announced that a total ban on the sale and import of more than 100 watts of incandescent lamps for general lighting, accompanied by the older generation of Chinese people decades of incandescent light is coming to the end of history.As described in the Nobel prize for physics, “incandescent lights illuminate twentieth Century, and led corn light will light up in twenty-first Century.
