A solar street lamp comprises a lamp post, a lamp and a storage battery. A solar collector is arranged above the lamp, a heat exchange pipe is arranged below the solar collector, the heat exchange pipe is connected with the storage battery, and the outer surface of the heat exchange pipe is provided with a thermal insulation layer. The solar street lamp is simple in structure and high in photoelectric converting efficiency, energy consumption and line installing cost of the street lamp are reduced, the street lamp is environment-friendly, and the service life of the lamp is prolonged.
Description
technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar street lamp. Background technique [0002] With the development of science and technology, solar street lamps have been developed. At present, the structure of solar street lamps is generally a street lamp body, solar panels, batteries and control circuits. Although it can reduce the use of municipal electricity, the cost of a single street lamp is very high. The main reason is that the photoelectric conversion efficiency per unit area of solar panels is low, and rain, snow and windy weather can easily damage solar panels on solar street lights, resulting in high maintenance costs. Contents of the invention [0003] In order to overcome the problems of low photoelectric conversion efficiency and high maintenance cost of the existing solar street light, the present invention provides a solar street light with high photoelectric conversion efficiency and low mainte...
