As the sun sets, the streetlights along the way home automatically turn on. Streetlight lenses are an essential component of lighting design, capable of concentrating divergent light sources and ensuring a well‑regulated, controllable distribution of light throughout the space, while effectively minimizing light waste and maximizing luminous efficiency. High‑quality streetlight lenses can also reduce glare, producing softer, more comfortable illumination. Yisite Optoelectronics explains what factors you should consider when selecting streetlight lenses: 1. Choosing the light spot pattern: Light spots come in three main shapes—circular, elliptical, and rectangular. Circular light spots have lower requirements for illuminance and coverage area and are typically used for residential‑area road lighting. Elliptical light spots can better address uneven illumination…

As the sun sets, the streetlights along the way home switch on. Streetlight lenses are an indispensable component of lighting design: they focus divergent light sources, ensuring a well‑regulated, controllable distribution of illumination throughout the space, while effectively minimizing light waste and maximizing luminous efficiency. High‑quality streetlight lenses can also reduce glare, producing softer, more comfortable lighting. Yisite Optoelectronics explains what factors you should consider when selecting streetlight lenses.

1. Selection of Light Spots for Streetlight Lenses

 

Light spots are categorized into circular, elliptical, and rectangular types. Circular light spots have lower requirements for illuminance and coverage area and are typically used for residential‑area road lighting. Elliptical light spots make efficient use of unevenly distributed light and light that extends beyond the roadway, offering strong focusing capability; they are generally employed on non‑motorized and motorized vehicle roads. Rectangular light spots also provide strong focusing, delivering uniformly distributed light onto the road surface to maximize light utilization; they are commonly used on motor vehicle thoroughfares and are highly favored by customers as street‑light lenses.

 

2. Angle specifications for streetlight lenses

 

Different road types have varying optical requirements. For instance, street lighting heights differ across highways, arterial roads, collector roads, local streets, and residential neighborhoods, necessitating distinct installation angles and specifications. It is essential to select appropriate beam angles to meet the lighting needs of pedestrians and motorists.

 

3. Materials for streetlight lenses

 

Common materials used for street‑light lenses include glass and silicone‑gel lenses. Silicone‑gel, with its excellent high‑temperature resistance, is often employed to encapsulate LED light sources. Glass, on the other hand, offers superior heat resistance and high transmittance, allowing for customizable optical properties; however, its heavier weight and fragility limit its applications. Newer materials—PC lenses and PMMA lenses—are both optical plastics that can be molded through injection or extrusion, delivering high production rates at lower material costs. Once adopted, they have quickly demonstrated significant advantages in the market. If you’re looking for cost‑effective street‑light lenses, PC and PMMA options are ideal choices.

 

In summary, when selecting street‑light lenses, factors such as lens specifications and the materials used should be taken into account. Choose the appropriate beam‑pattern and beam‑angle specifications based on the installation location, and ensure that the glass lens cost is reasonable. For a cost‑effective option, lenses made from the advanced materials PC or PMMA—mentioned earlier—are recommended. By considering these aspects, you can confidently select the most suitable street‑light lens.
