What is lamp street solar design experience?

        Lamp street solar system design is a technology thing.Today we want to introduce what is the lamp street solar design experience.

        According to the "Urban Road Lighting Design Standards": the average illuminance of the expressway is 20lx, the uniformity is 0.4, the average illuminance of the main road is 15lx, the uniformity is 0.35, the average illuminance of the secondary trunk is 8lx, the uniformity is 0.35, the average illumination of the branch is 5lx, uniformity 0.3. All in one solar street lamp are now in use, due to technical conditions, LED power is 30~100w, light efficiency is 50~80lx/w, road illumination is low, the author has done tests, the pole height is 8.5 meters, the spacing is 30 meters, the light source 2×50wLED The lamp has a illuminance of 19lx under the lamp, 11lx between the two lamps, and 3.5lx at the darkest point.

      The working hours of all in one solar street lamp should be the same as the working requirements of general street lamps. The design should consider the short-term sunshine hours in winter, and the working time should be above 12 hours. Since the LED lights are greatly affected by the weather, in the event of continuous rainy days, the LED lights lack power and cannot be used. There is no standard in the country for LED street lights in low irradiance (continuous rainy days), allowing for minimum working hours without provisions, now generally according to the lighting manufacturers and local meteorological conditions, should work in low illuminance (continuous rainy days) work in the situation for 15 to 20 days. The capacity of solar panels and batteries should be fully considered in the design. The working voltage of the all in one solar street lamp is generally 12V or 24V. Which is a safe voltage and does not make electrical protection grounding. However, the LED street light metal pole should be grounded and the grounding resistance is not more than 10 ohms.
