What Are the Advantages of LED Street Lamps in Street Lamp Applications

The LED street lamp with a special light design is used on the street lamp to offset the light-emitting angle of the street lamp and improve the utilization rate of roadside lighting. According to the rectangular spot with the aspect ratio of 2:1, the adjacent spot There is no shadow between them, and a bright uniform light band is formed on the road surface, which makes the lighting design of the current traffic road more consistent. Without increasing the height of the lamp post, it can meet a wide enough lighting range and improve the lighting of the street lamp. Efficiency reduces the lighting power density of the road. Therefore, high-power LED street lamps used for energy saving and environmental protection are used as road lighting. Compared with traditional high-pressure sodium lamps, they have incomparable advantages: 1. Low maintenance cost of LED street lights: Compared with traditional street lights, the maintenance cost of LED street lights is extremely low. After comparison, all input costs can be recovered in less than 6 years. The LED street lamp has an automatic control energy-saving device, which can achieve the greatest possible reduction in power and energy saving under the condition of meeting the lighting requirements of different periods. It can realize computer dimming, time period control, light control, temperature control, automatic inspection and other humanized functions. With the rapid growth of the national economy, the contradiction between my country's energy supply and demand has become increasingly prominent. There is a serious shortage of power supply, and energy conservation is an urgent problem to be solved. Therefore, the development of a new type of high-efficiency, energy-saving, long-life, high color rendering index, and environmentally friendly LED street lamps is of great significance to the energy saving of urban lighting. The lighting mechanism is different. Since the LED street lamp is a semiconductor device, its effective life can reach 50,000 hours (that is, the light attenuation is less than 30% after 50,000 hours), which is much higher than that of sodium lamps and metal halide lamps. (Their life is about one hour). ). 2. Since the LED street lamp is a semiconductor material, non-filament and other additional materials, the LED street lamp has good impact resistance. 3. The color rendering index of LED street light sources can reach above 80, which is closer to natural light. In this case, the human eye can distinguish things more easily and is conducive to driving safety. The color rendering index of high-pressure sodium lamps is only 200.4. Traditional gas discharge lamps, such as high-pressure sodium lamps, have a preheating process when they are started, which not only wastes energy, but also is not conducive to intelligent control. Due to the essential difference of LED street light sources, there is no'start time' issue. It can work normally after power-on, and it is very convenient to realize intelligent energy-saving control. 5. Since traditional street light sources use mercury vapor light-emitting mechanism, the disposal of waste light sources is also an urgent problem to be solved in the world. At the same time, the light-emitting mechanism of the traditional light source determines that it emits ultraviolet rays that are harmful to the human body. The LED street light source is solid-state lighting, does not contain harmful substances such as mercury, does not emit ultraviolet radiation, and is an environmentally friendly light source. 6. In the optical system, the traditional street light source is omnidirectional, half of the light is reflected by the reflector, and the reflector is used to absorb part of the light, so the light loss is relatively large. Because the street lamp is one-way, the utilization rate of lighting and light is higher than that of the traditional street lamp. 7. The distribution curve of traditional street lamps is determined by the reflector, which has certain limitations. The LED street light source is a distributed light source. Through the design of each light source, the light source of the lamp can display an ideal batwing. By reasonably controlling the light distribution, the road point is rectangular, and higher light can be obtained within the effective illumination range. . Uniformity of illuminance. 8. More perfect automatic control (optional): different brightness can be set according to the needs of different time periods to further improve the energy-saving effect. If it is bright at 7 o'clock in the evening, it is 200W. When it was 12 o'clock in the middle of the night, the brightness was very low. It is automatically adjusted to 100W, which can also save 60W of electricity.

I want light controlled by one switch, not two

The picture with the wires showing where there are 2 red and 2 white wire look like you had a 4-way switch there meaning there is actually 3 locations where the switches shut off the lights. If you splice together the 2 whites under one wirenut and the 2 red under another wire nut that will take the switch out of the picture. Then you can go to the other location and splice the wire that is on the black screw with one of the wires that is on the screw above either the red traveler or the white traveler. That will take the other switch out of the picture also leaving the last 3-way there
