What are the characteristics and advantages of led street lights
1. Its own characteristics: unidirectional light, no light diffusion, to ensure lighting efficiency.
2. The
LED street light has a unique secondary optical design, which irradiates the light of the LED street light to the area that needs to be illuminated, further improving the lighting efficiency and achieving the purpose of energy saving.
3. LED has reached 110-130lm/W, and there is still a lot of room for development, and the luminous efficiency of high-pressure sodium lamps increases with the increase of power. Therefore, the overall luminous efficiency of LED street lamps is stronger than that of high-pressure sodium lamps; (this The overall luminous efficiency is theoretical, in fact, the luminous efficiency of high-pressure sodium lamps above 250W is higher than that of LED lamps).
4. The light 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 is above 75. From the perspective of visual psychology, to achieve the same brightness, the average illuminance of LED street lamps can be It is more than 20% lower than that of high pressure sodium lamps.
5. The light decay is small, less than 3% in one year, and it still meets the road requirements after 10 years of use, while the high-pressure sodium light has a large decay, which has dropped by more than 30% in about a year. Therefore, LED street lights are designed in terms of power usage. can be lower than high pressure sodium lamps.
6. LED street lights have automatic control and energy-saving devices, which can achieve the maximum possible power reduction and save energy when meeting the lighting requirements of different periods, and can realize computer dimming, time-segment control, light control, temperature control, automatic inspection, etc. Humanized function.
7. Long service life: It can be used for more than 50,000 hours and provides a three-year quality guarantee. The disadvantage is that the life of the power supply cannot be guaranteed.
8. High luminous efficiency: using chips of ≥100LM or more can save energy by more than 75% compared to traditional high-pressure sodium lamps.
9. Easy installation: no need to bury cables, no rectifiers, etc., directly connect to the lamp pole or nest the light source into the original lamp shell.
10. Excellent heat dissipation control: The temperature in summer is controlled below 45 degrees, and passive heat dissipation is adopted, and the heat dissipation guarantee in summer is insufficient.
11. Reliable quality: The circuit power supply adopts high-quality components, and 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 uniform light color is not sacrificed to improve brightness, so as to ensure uniform light color without aperture.
13. LED does not contain harmful metal mercury, which will not cause harm to the environment when it is scrapped.
