What are the material and appearance specifications of the street lamp lens?

Because street lights have different optical requirements for different roads, such as: street light height, distance between street light poles, and types of roads (arterial roads, trunk roads, branch roads, courtyard areas, etc.), the angle requirements of street light lenses are also different. . Choose different street lamp lenses according to different needs. The following editor will introduce the material and appearance specifications of street lamp lenses. Welcome to read!

The material of the street lamp lens:

1. Glass lens

• Due to the high temperature resistance and high penetration rate of glass materials, a large part of LED street light factories are still in use.
• However, due to the heavy weight, brittleness and high cost of glass, the scope of its use is limited.

2. pc or pmma material

• These two materials belong to the category of optical plastics, which can be formed by injection molding, which is easy to achieve aspherical concentrating and reduce the phenomenon of macula.
• However, the penetration rate of pc and pmma is second only to that of glass, and the temperature resistance is not as good as that of glass materials.
• But pc and pmma have significant advantages in material and production cost.

Lens specifications:

1. single lens

• Multiple single street light lenses are used in combination (lens and LEDs are one-to-one), which has the advantage of flexible use.
• For example, how many LEDs you want to choose, how many LED lenses you use, and how you want to arrange them.

2. Street light lens module (multiple)

• In order to effectively utilize the lamp space and reduce the structural size and weight of the lamp, a considerable number of manufacturers currently use the street lamp lens module first, of which the 4*7 structure is mostly 28 heads.
• The street lamp lens module can also cooperate with the waterproof structure of the lamp.
