LED Street Light Lens Basic Concept
- Aug 13, 2018 -

The street light lens is made according to the law of light refraction. A lens is an optical component made of a transparent substance. The street light lens is a refractor whose refractive surface is two spherical surfaces, or a spherical transparent surface. It has a real image and a virtual image. Lenses can generally be divided into two broad categories: convex lenses and concave lenses. The central part is thicker than the edge part, which is called a convex lens, which has three kinds of convex, convex, convex and concave; the central part is thinner than the edge part, which is called concave lens, flat concave, convex and concave.

LED lenses are generally: silicone lenses, because silicone is resistant to high temperatures, so it is usually packaged directly on the LED chip. Generally, the silicone lens is small in volume and has a diameter of 3-10 mm. The LED lens is generally closely associated with the LED, and it helps to improve the light extraction efficiency of the LED and the optical system in which the lens changes the light field distribution of the LED.

The LED lens is an optical system that is closely associated with the LED and contributes to improving the light extraction efficiency of the LED and changing the light field distribution of the LED. The high-power LED lens/reflector is mainly used for collecting and guiding light of high-power LED cold light source products. The high-power LED lens designs the light distribution curve according to the angle of the different LEDs, and increases the optical reflection to reduce the light loss and improve the light efficiency.
