Selection of lens material:
_{The material of the lens also has a significant impact on its performance and durability. Common lens materials include:
1.PMMA (polymethyl methacrylate): high transparency, strong weather resistance, often used in outdoor lighting, and low cost.
2.PC (Polycarbonate): It has stronger impact resistance and better UV resistance, and is suitable for environments that require high-intensity use.
3.Glass: Although glass lenses are heavier, their optical properties are stable and they are often used in high-end street lighting products.
S4.ilicone: good flexibility, can be used for some specially designed street lights.}
Lens Selection Considerations:
_{1.Light source type: Various types of light sources (like LEDs, metal halide lamps, sodium lamps, etc.) impose distinct design demands on lenses. LED lamps frequently call for more accurate optical designs, whereas traditional sodium or halogen lamps might utilize simpler lenses.​
2.Illumination range and beam angle: The choice of lenses is dependent on the road width, the required uniformity of lighting, and the beam angle. For instance, urban streets may need a broader beam, while highways demand narrower, more focused beams.​
3..Anti-glare requirements: During the design of street lights, particular attention must be paid to preventing light from directly reaching the eyes of drivers or pedestrians, so as to stop glare from impairing vision. An appropriate lens design can effectively manage glare and offer comfortable lighting.​
4.Luminous efficiency and energy conservation: Modern street lamp design is placing more and more emphasis on enhancing light efficiency and saving energy. The lens design must therefore maximize the utilization of the light source's energy and minimize unnecessary light dispersion.​
5.Durability and protection: Lens materials need to be resistant to weathering and aging, and capable of adapting to different climatic conditions, especially when employed outdoors.​
In general, the selection of street lamp lenses should be made based on actual needs, the type of light source, and the lighting effect. The goal is to provide a uniform, effective, and energy-efficient lighting solution.}
