What Are The Advantages Of High-power LED Street Lights?
- Jan 08, 2019 -

First, unidirectional light

The characteristics of the LED street light bar itself - the unidirectional nature of light, no light diffusion, to ensure light efficiency.

Second, high light efficiency

The LED street light has a unique secondary optical design that illuminates the area of the LED street light to the desired illumination area, further improving the illumination efficiency. Energy saving has been achieved. At present, the light source efficiency of LED has reached 100lm/w, and there is still a lot of room for development, the theoretical value reaches 200lm/w. The luminous efficiency of the high-pressure sodium lamp increases with the increase of power. Therefore, the overall luminous efficacy LED street lamp is stronger than the high-pressure sodium lamp.

Third, high color rendering

The 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 reaches 70 or more. From the perspective of visual psychology, the same brightness is achieved, and the illuminance of LED street lamps can be higher than the high voltage. The sodium lamp has been reduced (refer to British road lighting standards.)

Fourth, the light decay is small

The light decay of LED street lamps is small, the light decay of less than 3% in one year, the use of the road still meets the requirements of road use lighting, and the high-pressure sodium light decays, which has dropped by more than 30% in a year or so. Therefore, the design of LED street lamps is using power. It can be lower than the high pressure sodium lamp.

Five, energy saving

LED street lights have automatic control energy-saving devices, which can achieve the maximum possible power reduction and save energy when meeting the lighting requirements of different time periods.
