Considerations for solar street light design

What are the precautions for solar street light design? 1. Light decay of lamps Light decay of lamps refers to the negative impact of optical system and lamp structure on the luminous flux of light sources. Contamination of the system leads to phenomena such as premature fading of illumination. In the design process of the luminaire, the material selection, shape, volume and sealing method of the reflector should take into account the problem of light decay. 2. Light source protection In the design of lamps, it is necessary to ensure that the light source has a reliable electrical connection, the contact resistance is small, and it will not loosen after vibration. In order to protect the light source and prolong the life of the light source, the internal structure of the lamp must be scientific and reasonable. In order to enhance the heat dissipation capacity of the lamps, the shape and size of the reflectors should be reasonably manufactured, the volume of the lamps should be appropriately enlarged, and the heat dissipation area should be increased, so that the light sources work at a suitable temperature to ensure stable, safe and reliable performance. 3. Thermal radiation problem and thermal energy utilization In addition to reflecting visible light, the light source will also generate a large amount of thermal radiation. Thermal radiation will make the lamp body temperature too high, affect the service life of the light source, and make the material of the lamp premature. Aging, more dangerous is that it may lead to leakage, fire and so on. Therefore, when designing lamps, try to use heat-resistant materials and low-emission light sources. When conditions do not allow, materials with poor thermal conductivity such as asbestos should be used. Isolating light sources, lighting materials and components with poor heat resistance, can also use heat dissipation methods, such as heat sinks and reflectors, to refract heat radiation, or rely on fans to force air circulation to dissipate heat as quickly as possible. When the indoor lighting load is as high as 20-40W/m2, the utilization of thermal energy becomes very important. At present, research on air-conditioning lamps has been carried out to effectively utilize the large amount of thermal radiation generated by the light source. 4. The design of lamps and lanterns should take into account both function and beauty. An important part of lighting design is to select suitable lamps and lanterns according to functional requirements and environmental conditions to coordinate lighting functions and decorative effects. Lamps are functional products, as well as rich information carriers and cultural forms. They are a comprehensive reflection of people's aesthetic taste, technological level and functional needs in the corresponding historical period. The design of lamps and lanterns should take into account many aspects such as function, material selection, shape, color, and craftsmanship. Luminaire design should also consider the overall relationship of the luminaire to the relevant space environment. Not only lighting, but the beauty of lamps and lanterns is also inseparable from the environment in which they are located, and can be integrated with the environment. 5. Integrated design of lamps In recent years, new design concepts and design methods have emerged. The interface modeling of furniture, furnishings, lamps and even space is no longer an independent decorative element, but is often combined in various ways, which not only exerts a decorative effect, but also expands the interior space.
