How to choose LED street lights will not be deceived? Many customers are worried about quality problems, but professional manufacturers will still put quality first! Quality is our rice bowl! However, Xiaobian still does not trust some customers, so we want to share the following knowledge:

1, LED street lights and conventional street lights are different, LED light source using low-voltage DC power supply, by GaN power type blue LED and yellow synthesis of efficient white, with high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index unique advantages, can be widely used in roads, LED street lights no light diffusion, to ensure light efficiency.

2, LED street lights have a unique secondary optical design, the light of LED street lights to the required lighting area, in order to achieve the purpose of energy saving, the overall light efficiency of LED street lights is stronger than that of high-pressure sodium lamps. LED street lights can be used with lenses, and the light range can be flexibly controlled after the lens is added, further improving the light efficiency.

3, LED street light color rendering is higher than high pressure sodium lamp, high pressure sodium lamp color rendering index is only about 23, and LED street light color rendering index reached more than 75, from the visual psychological point of view, to achieve the same brightness, LED street light illuminance can be reduced by more than 20% on average than high pressure sodium lamp, light decay is also the advantage of LED street light, a year of light failure of less than 3%, The use of 10 years still meet the requirements of the road, while the high pressure sodium light decline, a year or so has fallen by more than 30%, LED street lights in the use of power design can be lower than the high pressure sodium lamp.

4, LED street lights have automatic control energy-saving device, can achieve the maximum possible reduction in power to meet the lighting requirements of different periods of time, save energy. It can realize computer dimming, time division control, light control, temperature control, automatic inspection and other humanized functions. Long life: can use more than 50,000 hours, provide three years of quality assurance.

5. The selection of LED street lights should take into account the light distribution of LED street lights. Light distribution refers to the light source (or lamps) in all directions of the space of the light intensity distribution, the same power of LED street lights, light distribution is often a wider range of exposure, the light is more uniform.

6, again to take into account the light decay of LED street lights. Light decay is the LED after a period of lighting, its light intensity will be lower than the original light intensity. There are two main problems affecting light decay, one is the LED chip quality is not good, the other is the LED chip heat dissipation is not good. Therefore, LED chips try to purchase regular manufacturers to slow down light decay, and the heat dissipation of lamps is closely related to the structure of lamps.
