As the Earth's resources become increasingly scarce, the basic rising cost of energy to increase investment, and a variety of safety and pollution hazards everywhere, solar energy as an "inexhaustible" security, environmental protection and new energy more and more attention. In addition, the development of solar photovoltaic technology and advances in green energy, LED Street Lights，solar energy street lamp, grass and other dual advantages of solar lighting products, applications development has gradually scale, solar lights, have become increasingly sophisticated. I want a peer reference design for solar lights bit.

According to "city road lighting design standards" requirement: the average fast road illumination 20lx, uniformity of 0.4, the average trunk road illumination 15lx, uniformity of 0.35, sub-distributors average intensity 8lx, uniformity of 0.35, the average slip illumination 5lx, uniformity 0.3. LED Street Light are in use, due to technical conditions, LED power small 30 ~ 100w, luminous efficiency 50 ~ 80lx / w, road illumination is low, I did the test, pole 8.5 meters high, spacing of 30 meters, the light source 2 × 50wLED light, lamp illumination 19lx, between two lights 11lx, most dark 3.5lx.

Number above the initial installation of lighting for the new illumination value, so the illumination is not satisfied with the trunk road expressway. Solar street lights should be in sub-distributors, with support on the road, the main road with caution.

LED lights daily working hours should work with the general requirements of street design should consider the short duration of sunshine in winter, their working time should be over in 12 hours. As the LED light influenced by the weather, rainy days in case of continuous lack of power and the LED lights can not be used. Countries are not normative for the LED lights in the low irradiance (continuous rainy days) case, allowing a minimum working time does not make provision, lighting manufacturers and are generally based on local meteorological conditions, should be in the low irradiance (continuous rainy days) working conditions work in 15 to 20 days. Should be fully considered in the design of solar
