As a green alternative to traditional lighting applications, solar street lights are separated from the mains, do not generate greenhouse gases, and can provide lighting even if the power is cut off for any reason. Solar street lights are completely self-sufficient and require little maintenance. If you are looking for a green option, solar street lights are definitely the one to choose. But there are also many users who will be entangled in the lighting effect of solar street lamps. How to judge whether the lighting effect of solar street lamps is good or not? The following Xiaobian from Zhengzhou Haopai will give you a detailed introduction to this problem.
1. Average illuminance. Many customers take an illuminance meter to measure under the lamp, and if the value is large, the brightness is good. This is very one-sided. The lighting effect of the street lights is to illuminate the entire road very brightly, not the place under the vertical street lights is very bright, and the two sides of the lights are not bright, showing different degrees of dark areas. The effect of this constant change of darkness and light will increase the driving risk of the driver, because the eyes suddenly transition from a very bright place to a very dark place, which will cause a short-term blind spot, and it is not easy to see the dark area in a short time. , resulting in an accident. In addition, driving on the road with flickering light and darkness for a long time is easy to get drowsy. Therefore, the brightness reference value of the road must be the average illuminance.
2. Uniformity. Uniformity is to consider the uniformity of the light hitting the road surface. For a road with good lighting effect, the light is evenly paved on the entire road, rather than bright and dark. Simple uniformity = minimum illuminance/average illuminance. The latest national standard is to require 0.3-0.4.
3. National standards. my country's urban road lighting design standards (the latest one is CJJ45-2015), there are also clear standards for 1-3 roads.
The above information on how to judge whether the lighting effect of solar street lights is good or not will be shared with you here. The lighting effect of solar street lights directly affects the subsequent use of solar street lights. Therefore, I hope everyone can learn to identify the lighting of solar street lights when choosing LED lamps. Don't be deceived by unscrupulous merchants, and remember to consume rationally.
