LED still need further develop

Time:2014/9/15  keywords:led street light


With the gradual development of LED lighting lamps and lanterns, auxiliary lighting and other public places in the rope, led high bay lighting lamps and lanterns is gradually replaced the traditional light source products, become a dark horse in the field of lighting, but the LED lighting technology has some difficulties need breakthrough:   As with traditional light source, LED light source will generate heat during work, it depends on the luminous efficiency of the whole.Under the effect of external electrical energy, the radiative recombination of electrons and holes in electroluminescent, radiate near the p-n junction of light only after the chip itself and encapsulating semiconductor media medium (air) to reach the outside world.Integrated current injection efficiency, radiation luminescence quantum efficiency, chip external light extraction efficiency, etc., in the end is only about 30-40% of input electric energy into light energy, the other 60-70% of the energy is mainly to the radiative recombination occurs in the form of lattice vibration into heat energy.   At present due to the lack of uniform standards of LED Lighting products, plus the companies own existing equipment facilities, and their respective work foundation and the technology development imbalance, caused to appear on the market of LED lighting application products different variety, performance, interchangeability, put forward severe challenges to the development of the industry, but also to some extent, restricted the  LED Street Light    lighting industry‘s healthy development.                                                                                                        About the company: E-Lite Semiconductor, Inc. is a veteran solid-state lighting company specializing in high quality, ultra-bright LED lighting product design and manufacturing for commercial and industrial applications.
