The advantages and disadvantages of solar street light lenses are analyzed as follows:

Increase the irradiation range: lenses are able to focus the light into a certain area, thus increasing the irradiation range of solar street lights. This is especially important for places that require extensive lighting to ensure that a larger area is fully illuminated.

Improve the brightness of lighting: the lens can focus the light into a smaller area, thus increasing the energy density of the light and making the lighting effect more intense. Through the focusing effect of the lens, the solar street light can emit brighter light, improving the visibility and safety of the road.

Energy saving: the use of lenses can make the light more focused and improve the lighting effect, thus reducing the power consumption of solar street lights. This helps extend the life of the solar cells and reduces overall energy consumption.

Reduce Glare: The optical design of the lens can effectively control the direction of light scattering and reduce the generation of glare. This is critical to improving the safety and comfort of roadway lighting by preventing glare from interfering with the vision of pedestrians and drivers.

Increased Cost: Lenses require a certain amount of cost to manufacture and install, which may increase the overall price of solar street lights. However, this cost is usually acceptable considering the improved lighting effect and reduced energy consumption brought about by the lenses.

Maintenance Difficulty: The lens may be affected by dust, dirt, and other pollutants, requiring regular cleaning and maintenance. If the maintenance is not timely, it may affect the light transmittance and lighting effect of the lens. Therefore, when installing solar street lights, you need to consider the cleaning and maintenance of the lens.
