LED (light emitting diode, abbreviated) is determined by semiconductor structure into a weak power to light, the solid-state light source in some good bias voltage and existing create, write hole and injection electron dispersed into the active area of the radiative recombination and emission of photons, LED street lamps electrical energy is straight converted into light power.

LED light bulb is often a significant component in the street lamps, the standard high pressure sodium lamp street lamps are generally utilised to 360 degrees higher pressure sodium lamp, optical losses of defects formed infinite waste of energy.

At present, the deterioration on the global atmosphere, nations in the improvement on the power of cleaning. With the rapid growth in the national economy, the contradiction among supply and demand in China, the beginning of a severe lack of power supply, energy saving is an urgent really need to address the question. Consequently, the development of new high efficiency, power saving, lengthy life, higher color index, environmental protection LED street lamps for energy-saving lighting city plays a crucial part in road lighting is closely connected to people's production and life, accelerate the method of city China, LED street lamps plus the direction of the light, low power consumption, good drive function, swift response high, lengthy service life, might be used for seismic, green environmental protection and so on. steadily into everyone's vision, has become the world's most existing source to replace the classic use of energy-saving light supply, a brand new generation of it, LED lamps will grow to be the ideal way to pick out LED energy-saving lighting lamps and also the regular higher stress sodium lamp lamp, higher energy LED street lamps fire choice low voltage DC energy supply, the power LED GaN Blue and yellow fluorescent powder and also the results price of white LED, high power, safety, power saving, environmental protection, lengthy life, rapidly response, the prevalent benefits of high colour index, might be widely utilised in city lighting housing obtainable computer handle, temperature of 135 degrees, low temperature resistance of 45 degrees.
