As a part of solar street light, LED street light head is considered inconspicuous compared with the battery board and battery, and it is nothing more than a lamp housing with a few lamp beads welded on it. If you have this kind of thinking, you are very wrong. Let us take a look at the advantages of LED street light head with solar street light factory Tianxiang today.
1. The characteristics of the LED street light head itself, the unidirectionality of light, and no light diffusion, ensure the lighting efficiency.
2. The LED street light head has a unique secondary optical design, which irradiates the light of the LED street light head to the area that needs to be illuminated, further improving the light efficiency and achieving the purpose of energy saving.
3. The light source efficiency of LED street light head has reached 110-130Im/W, and there is still a lot of room for development, with a theoretical value of 250Im/W. The luminous efficiency of high-pressure sodium lamps increases with the increase of power. Therefore, the overall light effect of LED street light head is stronger than that of high-pressure sodium lamps.
4. The light color rendering of LED street light head is much higher than that of high-pressure sodium lamp. The color rendering index of high-pressure sodium lamp is only about 23, while the color rendering index of LED street light head reaches more than 75. From the perspective of visual psychology, it can achieve the same brightness. LED street The illuminance of the light head can be reduced by more than 20% on average compared with the high pressure sodium lamp.
5. The light decay of LED street light head is small, the light decay is less than 3% in one year, and it still meets the road illumination 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 one year. Therefore, LED The street light head can be designed to use less power than high-pressure sodium lamps.
6. The led street lamp head has an automatic control energy-saving device, which can reduce the power as much as possible and save electric energy under the condition of meeting the lighting requirements of different periods.
7. LED is a low-voltage device, and the voltage to drive a single LED is a safe voltage. The power of a single LED in the series is 1 watt, so it is a safer power supply than using a high-voltage power supply, especially suitable for public places (for example: street lighting) , factory lighting, automotive lighting, civil lighting, etc.).
8. Each unit LED chip has only a small volume, so it can be fabricated into devices of various shapes, and is suitable for variable environments.
9. Long service life, can be used for more than 50,000 hours, and provide three-year quality assurance.
10. Easy to install, no need to add buried cables, no rectifiers, etc., directly install the LED street light head on the lamp pole or nest the light source into the original lamp housing.
11. Reliable quality, all high-quality components are used in the circuit power supply, and each LED has individual over-current protection, so there is no need to worry about damage.
12. LED street lamp does not contain harmful metal mercury, unlike high-pressure sodium lamps or metal halide lamps that do harm to the environment when they are scrapped.
