LED street lamp

time:Nov 11, 2022 Views:



1. Its own characteristics - unidirectional light, no light diffusion, to ensure lighting efficiency.


2. LED street lamp has a unique secondary optical design, which can illuminate the light of LED street lamp to the required lighting area, further improving the lighting efficiency, so as to achieve the purpose of energy conservation.


3. The 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 high pressure sodium lamp increases with the increase of power, so the overall luminous efficiency of LED street lamp is stronger than that of high pressure sodium lamp; (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 performance 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 more than 75. From the perspective of visual psychology, the same brightness can be achieved. The illumination of LED street lamps can be reduced by more than 20% on average than that of high-pressure sodium lamps,.


5. The light attenuation is small, less than 3% in one year, and it still meets the road requirements after 10 years of use. However, the high pressure sodium lamp has declined by more than 30% in about one year. Therefore, the LED street lamp can be designed to use less power than the high pressure sodium lamp.


6. LED street lamps are equipped with automatic control energy-saving devices, which can reduce the power as much as possible and save electric energy when meeting the lighting requirements of different periods. It can realize humanized functions such as computer dimming, time division control, light control, temperature control and automatic inspection.


7. Long service life: it can be used for more than 50,000 hours, providing three years of quality assurance. The disadvantage is that the life of the power supply is not guaranteed.


8. High luminous efficiency: chips ≥ 100LM are used, which can save more than 75% energy compared with traditional high-pressure sodium lamps.


9. Simple installation: no need to bury cables, no need for rectifiers, etc., directly connect 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. The heat dissipation guarantee in summer is insufficient.


11. Reliable quality: all circuit power supplies are made of high-quality components, and each LED has its own 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 and will not cause harm to the environment when scrapped.


Based on the above principles, the energy saving effect is remarkable, and it can save more than 60% electricity instead of high-pressure sodium lamp.
