Features of LED street lamps
LED street lamp has automatic control energy saving device, which can realize the maximum possible reduction of power and save energy in meeting different lighting requirements. Can realize the computer dimming, time control, light control, temperature control, automatic inspection and other user-friendly features.
2, LED street lamp has a unique two optical design, the LED street light exposure to the required lighting area, further improve the lighting efficiency, in order to achieve energy-saving purposes.3, LED has reached 110-130lm/W, and there is still great room for development, the theoretical value of 360lm/W. The luminous efficiency of high pressure sodium lamp is only increased with the increase of the power, therefore, the overall optical efficiency of LED lamp is better than high voltage sodium lamp; (the overall efficiency of light is theoretical, light effect actually more than 250W higher than that of LED high pressure sodium lamp).4, LED street light color is much higher than that of high pressure sodium lamp, high pressure sodium lamp color index is only about 23, while the LED lamp color index reached more than 75, from the point of view of visual psychology, achieve the same brightness, illumination LED lamp can average 20% lower than high pressure sodium lamp,.5, a small decline, a year decline of less than 3%, 10 years still reached the requirement of road, and high pressure sodium lamp failure, a year has decreased by more than 30%, therefore, LED lamps used in the design of power can be lower than high pressure sodium lamp.
LED street lamp is different from conventional, LED light source adopts low voltage DC power supply, by the high white GaN based blue LED and yellow synthesis, has the advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index unique advantages, can be widely used in the road. Cover can be made, high temperature up to 135 degrees, low temperature resistance up to -45 degrees. 1, the characteristics of its own - one-way light, without the proliferation of light, to ensure the efficiency of light.
