solar street light design considerations

1. Light decay of street lamps The light decay of street lamps refers to the negative influence of the optical system and the structure of the street lamps on the luminous flux of the light source. In the planning process of street lamps, the material selection, shape, volume and sealing method of the reflector should take into account the problem of light decay. 2. Light source maintenance In the design of street lamps, it is necessary to ensure that the light source has a reliable electrical connection, the touch resistance is small, and it will not loosen after vibration. In order to maintain the light source and prolong the life of the light source, the internal structure of the street lamp must be scientific and reasonable. In order to enhance the heat dissipation capacity of the street lamp, the shape and size of the reflector should be reasonably made, which can appropriately expand the volume of the street lamp, increase the heat dissipation area, and make the light source work at a suitable temperature to ensure stable, safe and reliable performance. 3. The problem of thermal radiation and the use of thermal energy In addition to reflecting visible light, the light source also has a lot of thermal radiation. Thermal radiation can cause the temperature of the street lamp to be too high, affect the service life of the light source, and cause the material of the street lamp to age prematurely. More dangerously, it may cause Therefore, when designing street lamps, try to use heat-resistant materials and low-radiation light sources. When conditions do not allow, materials with poor thermal conductivity such as asbestos should be used to block light sources and heat-resistant ones. Lighting materials and components can also use heat dissipation methods, such as heat sinks and reflectors, to refract heat radiation, and can also rely on fans to force air circulation to dissipate heat quickly. When the indoor lighting load is as high as 20-40W/m2, the use of heat energy becomes very important. At present, the research on air-conditioning street lamps has been carried out, the purpose is to effectively use many heat radiation generated by the light source. 4. Street lamp design should combine function and beauty. An important part of lighting street lamp design is to select suitable street lamps according to functional requirements and environmental conditions, and to reconcile lighting functions and decorative functions. Street lamp is a functional product, and it is also a rich information carrier and cultural form. It is a comprehensive reflection of people's aesthetic taste, scientific and technological level, and functional needs in the corresponding historical period. Street lamp design should be in function, material selection, shape, color, and technology. Coordinate. Street lamp planning should also take into account the overall connection between street lamps and the relevant space environment. Not only lighting, but also the aesthetics of street lamps are inseparable from the environment where they are located and can be integrated with the environment. 5. Integrated planning of street lamps In recent years, new planning concepts and planning methods have emerged. The interface modeling of furniture, furnishings, street lamps and even space is no longer an independent decorative element, but is often combined in various ways. Together, they play a decorative role and expand the interior space.
