What are the advantages of LED road lamps compared with traditional high-pressure sodium lamps?

LED street lamps with special light shape design are applied to the lamps of street lamps, which can offset the luminous angle of lamps and improve the utilization rate of roadside lighting; According to the length width ratio of the rectangle, a light spot with a length width ratio of 2:1 can be generated, so that shadows will not appear between adjacent light spots, and a bright light band with uniform illuminance can be formed on the road, which is more consistent with the current lighting design of traffic roads. It does not need to increase the height of the lamp pole to meet the requirements of a sufficiently wide range of illumination, and it also improves the lighting efficiency of lamps and reduces the lighting power density of roads, In order to truly achieve energy conservation and green environmental protection, high-power LED street lamps can be used as road lighting,

1. Different light-emitting mechanisms. As LED street lamp is a semiconductor device, its effective life can reach 50000 hours (that is, after 50000 hours, the light attenuation is less than 30%), which is much higher than sodium lamp and metal halide lamp (their life is about 12000-15000 hours).

2. As LED street lamp is a semiconductor material without filament and other additional materials, it has good seismic resistance.

3. The color rendering index of LED street lamp light source can reach more than 80, which is closer to natural light. In this case, the human eye can easily identify things, which is conducive to driving safety; The color rendering index of high-pressure sodium lamp is only 20-30.

4. The traditional gas discharge lamp, such as high-pressure sodium lamp, has a preheating process when starting, which wastes energy and is not conducive to intelligent control; LED street lamps are essentially different in light sources, so there is no problem of "starting time". They can work normally immediately after being powered on, and can easily realize intelligent energy-saving control.

5. Because the traditional street lamp light source uses the mechanism of mercury vapor to emit light, the disposal of waste light sources is also a problem that needs to be solved all over the world. At the same time, the emission mechanism of traditional light sources determines that it will emit harmful ultraviolet rays. LED street lamp light source is solid state lighting, without harmful substances such as mercury and other elements, and will not emit ultraviolet light. Therefore, it is an environmental light source.

6. In the optical system, the traditional street lamp light source is omnidirectional, half of the light needs to be reflected by the reflector, and the reflector needs to absorb part of the light, so the light loss is relatively large. As Led Flood Lights Suppliers are unidirectional, the utilization rate of light is higher than that of traditional street lamps.

7. The light distribution curve of the traditional street lamp is determined by the reflector, so it has certain limitations. The LED street lamp light source is a distributed light source, which can make the light source of the lamp take the shape of an ideal bat wing through the design of each electric light source. By reasonable control of the light distribution, the light spot on the road surface is rectangular, and higher illumination uniformity can be obtained within the effective irradiation range.

8. More perfect automatic control (optional): different brightness can be set according to the needs of different time periods to improve the energy saving effect. For example, 200W is on at 7:00 p.m., and when there are few people at 12:00 p.m., the brightness is automatically adjusted to 100W, among which 60W can be saved.
