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. Types of light sources: Different kinds of light sources—such as light-emitting diodes (LEDs), metal halide lamps, and sodium lamps—place unique requirements on lens design. LEDs often require more precise optical designs, while conventional sodium or halogen lamps can typically work with simpler lens configurations.
2. Illumination scope and beam angle: The selection of lenses depends on road width, the required lighting uniformity, and the beam angle. For example, urban roads may require a wider beam, whereas highways need narrower, more concentrated beams.

3. Anti-glare requirements: Special attention must be paid to avoiding direct light exposure to the eyes of drivers or pedestrians during street lamp design, so as to prevent glare from affecting visibility. A properly designed lens can effectively control glare and deliver comfortable lighting conditions.

4. Luminous efficiency and energy conservation: Modern street lamp design is attaching increasing importance to improving luminous efficiency and saving energy. Consequently, lens design should maximize the utilization of light source energy and reduce unnecessary light scattering to the greatest extent possible.

5. Durability and protective performance: Lens materials must be weather-resistant and anti-aging, and able to adapt to various climatic conditions—especially since they are mostly used in outdoor environments.

In summary, the choice of street lamp lenses should be determined by practical needs, light source types, and desired lighting effects. The ultimate objective is to provide a lighting solution that is uniform, efficient, and energy-saving.
