【 Solar street lamps factory 】 Solar LED street lamp brightness and scope

Solar LED street light illumination and scope: according to 'city road lighting design standard' regulation: expressway 20 lx, the average illuminance on the evenness of 0. 4, section of the average illuminance on the 15 lx, evenness 0. 35, one average illuminance 8 lx, evenness 0. 35, branch, on average, according to

solar LED street light illumination and scope:

according to the regulation of city road lighting design standards: expressway 20 lx, the average illuminance on the evenness of 0. 4, section of the average illuminance on the 15 lx, evenness 0. 35, one average illuminance 8 lx, evenness 0. 35, 5 lx branch average illuminance, evenness 0. 3. Now in use of LED street light, because of the technical conditions, small power LED 30 ~ 100 w, 50 ~ 80 lx/w light efficiency, low road illumination, the author tested, boom is 8. 30 meters, 5 meters, spacing light 2 & times; 50 wled light, the light intensity of illumination and lx, 11 lx, between the two lights the dark 3. 5lx。

more than the number for the new install lamps and lanterns of initial illuminance value, so the intensity of illumination is not meet of expressway and distance. Solar street lamps should be used on one, branch, the main road with caution.

the LED street lamp with daily work time should be lights work general requirements, design should be considered in the winter sunshine time short, the working hours will be able to over 12 hours. Because the leds are greatly influenced by the weather, in case of continuous rainy day will make leds is lacked electricity and cannot be used. Countries now without the specification for the LED street light in low irradiance, LED street lamp, stipulates the allowed minimum work time no, now generally according to lamps and lanterns and the local meteorological condition, should work in low-rising illumination conditions in 15 to 20 days. Should be given due consideration in the design of solar panel and battery capacity.

the working voltage of LED street light for 12 v or 24 v, safety voltage, do not do the electrical grounding protection. But LED street light metal light pole should be tested for lightning protection grounding, grounding resistance is not more than 10 ohms.
