LED street lamp

1, Features LED lights - unidirectional characteristics of light, no light diffuse ensure the efficiency of light.
2, 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.
3, 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.
4, Color rendering index of LED street light is much higher than High Pressure Sodium lamp. High pressure sodium lamp color rendering index is only 23, while the LED lights color rendering index is 75 or more, to achieve the same brightness, illumination LED street lights mean you can lower power than the high pressure sodium lamp.
5, 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.
6, LED lights with automatic control energy-saving devices, can be implemented in time to meet the lighting requirements of different circumstances the maximum possible reduction in power and save energy. LED lights can achieve computer dimming control sub-period, light control, temperature control, remote control, automatic inspection and other user-friendly features.
7, LED are low voltage, single LED drive voltage is safe, single LED 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.).
8, Each LED unit only a small volume, it can be prepared into various shapes of devices, and for the environment variable.
9, long life: can be used for more than 50,000 hours, provide three years of quality assurance.
10, High luminous efficiency: ≥100LM per watt,it can save more than 75% compared to traditional high pressure sodium lamp.
12, excellent thermal control: summer temperature at below 45 degrees, and the use of passive cooling, to protect the summer heat.
13, Quality reliable: the power supply are used all high-quality components, each LED has a separate over-current protection, without any risk of damage.
14, light color uniform: without lens, not to increase the brightness at the expense of uniform light color, so as to ensure no aperture light color uniform.
15, LED does not contain harmful metal mercury, unlike high pressure sodium or metal halide lamps at end of life damage to the environment.

LED lighting technology developed very quickly, high-power LED light effect has reached 100lm / W or more, which makes the city street lighting saving energy possible. LED lights, especially in high-power LED lights, at a rapid rate impact on traditional street market. LED lights now been applied to urban expressway, trunk road, sub-ways, branch ways, factory, school, park, residential quarters, courtyards and other road lightings.
