Technical Field

Background

A light Emitting diode (led), which is a solid semiconductor device capable of converting electrical energy into visible light, can directly convert electricity into light. The heart of the LED is a semiconductor wafer, one end of the wafer is attached to a support, the other end of the wafer is a cathode, and the other end of the wafer is connected with an anode of a power supply, so that the whole wafer is packaged by epoxy resin. The semiconductor wafer is composed of two parts, one of which is a P-type semiconductor in which holes predominate and the other of which is an N-type semiconductor in which electrons predominate. When the two semiconductors are connected, a P-N junction is formed between them. When current is applied to the wafer through the wire, electrons are pushed to the P region where they recombine with holes and then emit energy in the form of photons, which is the principle of LED lamp illumination. The wavelength of light, i.e., the color of light, is determined by the material forming the P-N junction, and the LED can directly emit red, yellow, blue, green, cyan, orange, violet, and white light. The LED is used as the indicating light source of instruments and meters at first, and then the LEDs with various light colors are widely applied to traffic signal lamps and large-area display screens, so that good economic and social benefits are generated. In the united states, a long-life, low-light visual efficiency 140 watt incandescent lamp, which produces 2000 lumens of white light, is originally used as the light source, as exemplified by a 12 inch red traffic light. After passing through the red filter, the light is lost 90% leaving only 200 lumens of red light.

In traditional module, LED lamp pearl paster is on PCB, that is to say that chip and lens are fixed, and the luminous angle that different lens controlled is different, and the luminous angle of lens that if use and the LED lamp that does not match to the environment of using can leave the facula on wall or floor.
