Color, led easily through chemical modification method, adjust the band structure and forbidden band width of materials, achieve red yellow green blue orange multi-color luminescence. The working voltage of 4301BW white light tube is small, and that of the red, orange, yellow, green and blue leds 4301BW with different colors increases in turn. Price, the price of LED 4301BW is becoming more and more common, because of the energy-saving characteristics of LED, perhaps in the near future, people will replace incandescent lamps with LED lamps. Some cities, schools and factories in China have been equipped with LED street lamps and energy-saving lamps. 4301BW LED category development, the first application of semiconductor p-n junction luminescence principle of LED light source came out in the early 1960s.
