LED Street Light Overview
LED street light with directional light, low power consumption, good driving characteristics, fast response, high shock resistance, long life, environmental protection and other advantages running gradually into people’s vision, become the new generation of the world’s most advantageous alternative energy-saving light to traditional light sources. Therefore, LED lights will be the best choice in energy-saving street lighting projects. That semiconductor lighting LED lights to light-emitting diodes as a light source. It is a solid cold light source with characteristics of environmental pollution, low power consumption, high light efficiency, long life and others.
LED Street Light Applications
LED street lighting technology developed very quickly, high-power LED street light effect has reached 100lm / W or more, which makes the city street lighting saving energy possible. LED street lights, especially in high-power LED street lights, at a rapid rate impact on traditional street market. LED street lights now been applied to urban expressway, trunk road, sub-ways, branch ways, factory, school, park, residential quarters, courtyards and other road lightings.
LED Street Light Features & Benefits
Features LED street lights – unidirectional characteristics of light, no light diffuse ensure the efficiency of light.
LED street lights have a unique optical design, it will light the desired lighting area, and furtherly improve the efficiency of light in order to save energy.
The LED street Light efficiency currently has 110-130lm / W, but there is still much more room for development, theoretical value of 250lm / W. Efficiency of high pressure sodium lamp luminous is increased with the increased power, therefore, the overall luminous efficiency of LED street lamp is stronger than high-pressure sodium lamps.

Lumens depreciation of LED street light is small, it is less than 3%, with 10 years still reached the road illumination requirements, but high-pressure sodium light fades large, about a year more than 30%, therefore, The power of LED street lights cab be designed lower than the high-pressure sodium lamps.
LED street lamp is low voltage, single LED drive voltage is safe, single LED street lamp power is 1 watt, so it is more secure than the high voltage power supply, especially for public places (for example: street lighting, industrial lighting, automotive lighting, commercial lighting, etc.).
Each LED unit only a small volume, it can be prepared into various shapes of devices, and for the environment variable.
High luminous efficiency: ≥100LM per watt,it can save more than 75% compared to traditional high pressure sodium lamp.
Quality reliable: the power supply are used all high-quality components, each LED has a separate over-current protection, without any risk of damage.
