in the efficiency of solar battery power and light source condition, the factors affecting the application of solar street light and there are many: the rationality of the intensity of solar radiation, solar battery components Angle, environmental temperature, the old and new battery level ( The old and new battery charging and power efficiency can reach more than 30% difference) And so on. Before determine the conditions, evaluate the application effect of solar street lights are not accurate. In the intersections, curve, ramp, railway crossings, and pedestrian crossing and other special location, usually set up the lamps, identify conditions for drivers and pedestrians. Both inside and outside the tunnel and the street from the city to the suburbs road lighting in the transitional period, should consider the adaptability of drivers' eyes to the light change. Street lamp power, plant height and longitudinal spacing is one of the important parameters of light distribution design. The combination of these three elements can achieve satisfactory lighting effect. Street lamp requires reasonable light distribution, good light, long service life and maintenance free operation throughout the year. High luminous efficiency, good color rendering, can immediately began to work in a cryogenic environment. Common lamps include incandescent lamp, high-pressure mercury lamp, high pressure sodium lamp, low voltage sodium lamp, electrodeless lamp, metal halide lamp, fluorescent lamp, etc. At present, the mainstream of road lighting products is still a high pressure sodium lamp. In recent years, electrodeless lamp as a new type of light source, because of its advocates energy conservation and emissions reduction, can get the average degree of road surface is better than traditional light sources.
