The difference between LED street lights and conventional street lights is that the LED light source is powered by low voltage DC and is powered by GaN-based power blue LEDs. High-efficiency white light with yellow synthesis has the unique advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index, etc. It can be widely used in roads. The cover can be made with high temperature resistance up to 135 degrees and low temperature resistance up to -45 degrees.


1, its own characteristics - the unidirectional nature of light, no light diffusion, to ensure light efficiency.

2, LED street light has a unique secondary optical design, the light of the LED street light is irradiated to the area of the required illumination, further improving the illumination efficiency to achieve energy saving purposes.

3, LED has reached 110-130lm/W, and there is still a lot of room for development, the theoretical value is 360lm/W. The luminous efficiency of the high-pressure sodium lamp increases with the increase of power. Therefore, the overall luminous efficacy LED street lamp is stronger than the high-pressure sodium lamp; (this overall luminous effect is theoretical, in fact, the luminous efficiency of the high-pressure sodium lamp above 250W is higher than that of the LED lamp. ).

4. The color rendering of LED street lamps is much higher than that of high-pressure sodium lamps. The color rendering index of high-pressure sodium lamps is only about 23, while the color rendering index of LED street lamps reaches 75 or more. From the perspective of visual psychology, the same brightness is achieved. The average illuminance of LED street lamps can be reduced by more than 20% compared with high-pressure sodium lamps.

5, light decay is small, the light decay of less than 3% in one year, still meets the road requirements after 10 years of use, and the high-pressure sodium light decays, which has dropped by more than 30% in a year or so. Therefore, LED Street lights can be designed to use lower power than high pressure sodium lamps.

6. LED street lights have automatic control energy-saving devices, which can achieve the maximum possible power reduction and save energy when meeting the lighting requirements of different time periods. It can realize computer dimming, time-segment control, light control, temperature control, automatic inspection and other humanized functions.

7, long life: can use more than 50,000 hours, providing three years of quality assurance. The downside is that the life of the power supply is not guaranteed.

8. High light efficiency: Using chips above ≥100LM, it can save more than 75% energy compared to traditional high-pressure sodium lamps.

9, easy to install: no need to add cables, no rectifiers, etc., directly installed on the pole or nested the original light shell.

10, excellent heat dissipation control: the summer temperature is controlled below 45 degrees, and the passive heat dissipation method is adopted, and the heat dissipation in summer is insufficient.

11. Reliable quality: All circuit power supplies are made of high quality components. Each LED has a separate overcurrent protection, so there is no need to worry about damage.

12. Uniform light color: no lens is added, and the uniform light color is not sacrificed to improve the brightness, so as to ensure uniform color without aperture.

13, LED does not contain harmful metal mercury, and will not cause harm to the environment when it is scrapped.

The energy saving effect of the above principle is remarkable, and the high-pressure sodium lamp can save more than 60% of electricity.

Low maintenance cost: Compared with traditional street lamps, the maintenance cost of LED street lamps is extremely low. After comparison, the total input cost can be recovered in less than 6 years.
