Composition and function of solar street lamp lighting system

　　 Solar street light system composed of LED light source, solar module, battery and all intelligent controllers. Solar street lights are composed of many solar cell modules connected in series and parallel to provide electrical energy for the entire lighting system.　　Solar street light intelligent controller, solar street light is controlled by microcomputer, light control, time control, manual control integrated dual output control operation. By separating a period of time, it can control the power of the load and set the programming arbitrarily.　　 It has many protection functions, such as voltage protection, safety lightning protection, over-current protection load, energy saving and low voltage protection, charging voltage protection, LED constant current source conversion and real-time recording function. The controller provides temperature compensation. The static average power consumption of the battery is ≤0.05MA, and the high/low temperature resistance laboratory performance test of -45℃~90℃ can guarantee a long time under the condition of high/low temperature of -35℃～75℃. Normal use.　　 With high-power LED chips, a single luminous flux ≥95-100 lumens/watt, a life span of 30,000 hours, an attenuation rate ≤3%/year, no flicker, and stable and reliable performance of solar street lights. Through clever design, the heat dissipation effect of the LED lamp holder is stronger than the general die-cast aluminum and aluminum alloy lamp holders. It has a modern appearance and unique shape.　　 Compared with traditional street lights, solar street lights have many advantages. It is a one-time investment, the investment cost can be recovered within three years, and free charge, no maintenance cost, long-term benefit. Solar street lights are ultra-low voltage products, which are safe and reliable in operation, fully automatic operation, complete protection functions, and no hidden dangers.
