Energy-Efficient and green high-power LED street light […]
Energy-Efficient and green high-power LED street light for road lighting, compared with traditional high-pressure sodium lamps, the Led Street Light manufacturer will introduce:
1. Since the LED street light is a semiconductor material, no filament, and other additional materials, it has good shock resistance.
2. LED street light source lighting lamp color rendering index can reach 80 or more, relatively close to natural light, the human eye is easier to distinguish things in this case, is conducive to driving safety; and the high-pressure sodium lamp color rendering index is only 20-30.
3. The illumination mechanism is different. Since the LED street lamp is a kind of semiconductor device, its effective life can reach 50,000 hours (that is, after 50,000 hours, the light decay is less than 30%), which is much higher than that of sodium lamps and metal halide lamps (their life expectancy) At 12000-15000 hours).
4. Conventional gas discharge lamps, such as high-pressure sodium lamps, have a preheating process at startup, which wastes energy and is not conducive to intelligent control. LED streetlights have fundamental differences in terms of light sources, and there is no "start-up time" problem. Power-on can work normally immediately, and it is very convenient to realize intelligent energy-saving control.
5. In the optical system, the traditional street light source is omnidirectional, half of the light is reflected by the reflector, and the reflector absorbs part of the light, so the light loss is relatively large. Since LED street lights are unidirectional, the utilization of light is higher than that of conventional street lamps.
6. Since the traditional street light source uses the mechanism of mercury vapor to emit light, the disposal of the waste light source is also an urgent problem to be solved in the world. At the same time, the light-emitting mechanism of the conventional light source determines that it emits ultraviolet rays harmful to the human body. The LED street light source is solid-state lighting. It has no harmful substances such as mercury and does not emit ultraviolet light. Therefore, it is an environmentally friendly light source.
7. The light distribution curve of the traditional street lamp is determined by the reflector, so it has certain limitations, and the LED street light source is a distributed light source, which can make the light source of the lamp be ideal batwing shape through the design of each electric light source. By reasonably controlling the distribution of light, the pavement spot is rectangular, and a high illumination uniformity is obtained within an effective illumination range.
8. More perfect automatic control (optional): Different brightness can be set according to the needs of different periods, which can improve the energy-saving effect. If it is bright at 7 p.m., it is 200W. When there are few people in the middle of the night, the brightness is automatically adjusted to 100W, which can save 60W.
