2. lighting fixture distance and fixture road width, fixture road width is smaller than the practical road width, which because the fixture distance is inversely proportional to the uniform illumination, for example, the uniform illumination when the lighting fixture distance is 20 meters is 30 lux, then if the lighting fixture distance reaches 40 meters , the uniform illumination is 15 lux.
3. Uniformity, uniformity in the useful area, the ratio of darker illuminance to brighter illuminance, usually when these lighting fixtures are closer, the uniformity will be higher, the lighting fixtures are bit far away, then the uniformity will be lower.
For LED street light products, the performance of the product is very important. Judging whether it is good or bad we should also check the lighting effect of it, and the time of lighting.
