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: Different types of light sources (such as LEDs, metal halide lamps, sodium lamps, etc.) have different design requirements for lenses. LED lamps often require a more precise optical design, while traditional sodium or halogen lamps may use simpler lenses.
2.Illumination range and beam angle: The selection of lenses depends on the width of the road, the uniformity of the lighting needs, and the beam angle. For example, city streets may require a wider beam, while highways require narrower, more concentrated beams.
3.Anti-glare requirements: When designing street lights, special consideration needs to be taken into preventing light from directly hitting the eyes of drivers or pedestrians, so as to avoid glare affecting vision. The right lens design can effectively control glare and provide comfortable illumination.
4.Luminous efficiency and energy saving: Modern street lamp design is increasingly focusing on improving light efficiency and energy saving, and the design of the lens must maximize the energy of the light source and reduce unnecessary light scattering.
5.Durability and protection: Lens materials need to be weather- and age-resistant, and able to adapt to different climatic conditions, especially when used outdoors.
In general, the choice of street lamp lens should be considered according to the actual needs, the type of light source and the lighting effect, with the aim of providing a uniform, effective and energy-efficient lighting solution.}
