What are the advantages of LED street lights compared with traditional street lights?

1. The characteristics of the solar LED street light itself - unidirectional light, no light diffusion, to ensure light efficiency; 2. The solar LED street light has a unique secondary optical design, irradiating the light of the LED street light to the required lighting. 3. The light source efficiency of solar LED has reached 100lm/W, and there is still a lot of room for development, with a theoretical value of 250lm/W. 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; 4. The light color rendering of solar LED street lamps is much higher than that of high-pressure sodium lamps, and the color rendering index of high-pressure sodium lamps is only 23. The color rendering index of LED street lamps is above 75. From the perspective of visual psychology, to achieve the same brightness, the illuminance of LED street lamps can be reduced by more than 30% on average compared with high-pressure sodium lamps, (refer to the British lighting standard); 5. Solar LED street lamps The light decay is small, the light decay in one year is less than 3%, and the illuminance requirements for road use are still met after 10 years of use, while the high pressure sodium light decay is large, and it has dropped by more than 30% in about a year. Therefore, LED street lights are used in the power design. It can be lower than the high pressure sodium lamp; 6. The LED street lamp has an automatic control energy-saving device, which can achieve the maximum possible power reduction and save energy under the condition of meeting the lighting requirements of different periods; 7. The solar LED is a low-voltage device, and the voltage to drive a single LED is 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 and mine lighting, automotive lighting, civil lighting, etc.); 8 , Each unit LED chip has only a small volume, so it can be prepared into various shapes of devices, and is suitable for variable environments. 9. Long service life: It can be used for more than 50,000 hours and provides a three-year quality guarantee. 10. High luminous efficiency: using chips of ≥100LM or more can save energy by more than 75% compared to traditional high-pressure sodium lamps. 11. Easy installation: no need to bury cables, no rectifiers, etc., directly install the lamp head of the street lamp on the lamp pole or insert the light source into the original lamp shell. 12. Excellent heat dissipation control: The temperature in summer is controlled at about 45 degrees, and passive heat dissipation is adopted. 13. Reliable quality: The circuit power supply adopts high-quality components, and each LED has its own over-current protection, so there is no need to worry about damage. 14. 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. Based on the above principles, high-power LED street lamps have a significant energy-saving effect, and can save more than 60% of electricity by replacing high-pressure sodium lamps. Low maintenance cost: Compared with traditional street lights, the maintenance cost of LED street lights is extremely low. After comparison, all investment costs can be recovered in less than 2 years.
