Why choose LED street lights for road lighting transformation
The difference between LED street lamps and conventional street lamps is that the LED light source adopts low-voltage DC power supply, high-efficiency white light synthesized by GaN-based power blue LED and yellow, which is efficient, safe, energy-saving, environmentally friendly, long-life, fast in response, and high in color rendering index. Unique advantages, can be widely used in roads. The outer cover can be made, high temperature resistance up to 135 degrees, low temperature resistance up to -45 degrees.
advantage:
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. The LED has reached 110-130lm/W, and there is still a lot of room for development, with a theoretical value of 360lm/W. The luminous efficiency of high-pressure sodium lamps increases with the increase of power. Therefore, the overall light efficiency of LED street lamps is stronger than that of high-pressure sodium lamps; (this overall light efficiency is theoretical, in fact, the light 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, the light decay in one year is less than 3%, and it still meets the road requirements after 10 years of use. However, the high-pressure sodium light has a large decay, and the power design can be lower than that of the high-pressure sodium light. It has dropped by more than 30% in about a year, so LED street lights can be designed to use lower power than high pressure sodium lamps.
6. The LED street light 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. It can realize computer dimming, time-segment control, light control, temperature control, automatic inspection and other humanized functions.
7. Long service life: It can be used for more than 50,000 hours and provides three-year quality assurance. The disadvantage is that the life of the power supply is not guaranteed.
8. High luminous efficiency: The use of chips of ≥100LM or more can save more than 75% of energy compared with 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 is controlled below 45 degrees in summer, 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 its own over-current 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.
Combining the above principles, the energy-saving effect is remarkable, and the replacement of high-pressure sodium lamps can save more than 60% of electricity.
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 6 years.
