About the LED street lamp technology development present situation and future development are discussed - (AddTime -2013-02-18

Countries actively promote the implementation of energy conservation and emission reduction projects, especially Chinese 200W led Flood light street lamp for business opportunities by large and be 200W led Flood light street lamp manufacturers pay more attention to. Street lamp lighting is an important part of the city, the traditional street lamp often USES high-pressure sodium lamp, high pressure sodium lamp, on the whole, the disadvantages of the low light efficiency caused by the huge waste of energy, therefore, the development of new type high efficiency, energy saving, long life, high color rendering index, environmental protection of city lighting energy saving lamps have very important significance. The 200W led Flood light street lamp features:

High power 200W led Flood light street light and conventional high-pressure sodium lamp street lamp is different, the high power 200W led Flood light street lamp light source adopts low voltage dc power supply, the GaN base power type blue 200W led Flood light and yellow phosphor powder synthesis efficient white light diode, 200W led Flood light (light emitting diode, known as 200W led Flood light ) is based on semiconductor PN junction formation by weak electricity can luminous efficiency solid-state light source, in a positive bias voltage and injection current flow into the hole and P, the electronic injection N in diffusion to a source area after the radiative recombination and emit a photon, energy directly into light energy.

200W led Flood light street lamp as light source, it and traditional street lamp light source is have many advantages.

1, 200W led Flood light street lamp itself has light beam, no light diffusion, guarantee the efficacy;
2, 200W led Flood light street lamp has a unique secondary optical design, the 200W led Flood light street lamp light irradiation to required lighting area, namely the road to further improve the light efficiency, to achieve energy saving purpose;
3, 200W led Flood light light source efficiency now has 100 lm/W, and to have the very big development space, the theoretical value can reach 250 lm/W. And high-pressure sodium lamp luminous efficiency is increased with the power to increase, therefore, the overall efficacy 200W led Flood light street light than high-pressure sodium lamp is strong;
4, 200W led Flood light street lamp light color rendering than high pressure sodium lamp, high pressure sodium lamp color rendering index only 23 or so, and 200W led Flood light street light color rendering index can reach more than 75, from visual psychological point of view, in order to achieve the same brightness, 200W led Flood light street lamp light average than high-pressure sodium lamp can be reduced by more than 20% (see British road lighting standard); And, in the middle level of vision, the human eye in high colour temperature environment than low colour temperature environment more easy to identify things, avoid the occurrence of certain hazardous state;
5, 200W led Flood light street lamp light failure is small, a year of less than 3% light failure, the use of ten years still achieve road use illumination requirements, therefore, 200W led Flood light street lamp in the use of the design of the power than high pressure sodium lamp is low;
6, 200W led Flood light street lamp can be adjustable light, can realize in the meet different time lighting requirements, the biggest possible to reduce power, save electricity,
7, 200W led Flood light is low voltage dc components, drive single 200W led Flood light voltage for safe voltage, so it is a more than using high voltage power supply safety of power supply, especially suitable for the public places. The characteristics of the dc that 200W led Flood light is especially suitable for solar energy, wind power and with;
8, each unit 200W led Flood light grain only a small volume, so can be prepared into various shapes of the device, and suitable for variable, YiZhen environment
