What are the characteristics of LED street light fixtures?
Its own characteristics-the light of the one-way, without the diffuse light, to ensure illumination efficiency. LED street light fixtures have a unique two times optical design, the LED street light to the lighting needs of the area to further improve the lighting efficiency in order to achieve energy-saving purposes.
LED has reached 110-130lm/w, but also has a lot of development space, the theoretical value of up to 360lm/w. And the high pressure sodium lamp luminous efficiency is increases with the power increase, therefore, the overall light effect LED street lamp is stronger than the high-pressure sodium lamp; (This overall light effect is theoretically, actually more than 250W high pressure sodium lamp's light efficiency is higher than the LED lamp).
LED street light color than high pressure sodium lamp, high pressure sodium lamp color index only about 23, and led street color index reached more than 75, from the visual psychological point of view, to achieve the same brightness, led street lighting average can be lower than high-pressure sodium lamp down more than 20%. light decay small, a year of light decay less than 3%, the use of 10 years still reach the road requirements, and high pressure sodium lamp decline, a year or so has fallen more than 30%, therefore, led street lighting in the use of power design can be lower than the high-pressure sodium lamp.
LED street lights have automatic control energy-saving devices, to meet the requirements of different periods of lighting under the maximum possible reduction of power, save energy. Can realize the computer dimming, time control, light control, temperature control, automatic inspection and other human functions.
