One-way 1, the characteristics of light, no light diffusion, ensure light efficiency.
2, LED street lamp has a unique two optical design, the LED street light illumination to the area, to further improve the efficiency of light, in order to achieve the purpose of energy saving.
3, LED has reached 110-130lm/W, but there is still a lot of room for development, the theoretical value of 360lm/W. And high-pressure sodium lamp luminous efficiency is with the power increase will increase. Therefore, the overall luminous efficiency of LED street lamp is better than high voltage sodium lamp strong; the overall light effect is theoretically actually 250W high pressure sodium lamp light efficiency higher than LED lamp).
4, LED street lamp light display color is much higher than that of high pressure sodium lamp, high pressure sodium lamp Hin color index only 23%, and LED street lamp significantly color index reached more than 75, from the perspective of visual psychology, achieve the same brightness, LED street lamp illuminance average decreased more than 20% compared to the high-pressure sodium lamp.
5 and small light attenuation, attenuation of a year of less than 3%, the use of 10 years still reached the requirements of the road, and high pressure sodium lights decline, about a year has dropped more than 30%. Therefore, LED street lamp in the design of the use of power can lower than the high-pressure sodium lamp.
6, LED street lamps have automatic control energy saving device, can achieve the maximum possible reduction of power in the case of meeting the requirements of different periods of lighting. Can realize the computer to adjust light, time control, light control, temperature control, automatic inspection and other human function.
7, long life: can be used for more than 50 thousand hours to provide three years of quality assurance. The shortage is that the life of the power supply can not be guaranteed.
8, easy installation: no need to add buried cable without rectifier, directly to the installation in pole connected or nested source original shell.
9, heat control is excellent: summer temperature control in the following 45 degrees, and the use of passive cooling, summer heat dissipation is insufficient.
10, reliable quality: circuit power supply all the high quality components, each LED has a separate over current protection, no need to worry about the damage.
11, color uniformity: without lens, not to increase the brightness and uniform light color so as to ensure no sacrifice, iris color uniformity.
12, LED does not contain harmful metal mercury, in retirement will not cause harm to the environment.
