Fresnel lens for LED projection lamp

APPLICATIONS OF FRESNEL LENS IN LED FIELD

Usually, Fresnel lens is cut into spherical surface shape in order to minimize the optical aberration of the image during imaging. The lens can better align an ideal point light source into a parallel light source. In real life, no light source is a real point light source, but solid state light emitters such as LEDs are very small, so as long as the distance between the lens and the LED is appropriate, it can be used as a point light source. Therefore, the Fresnel lens produced by Yutai can align the LED output light to parallel light, while the traditional incandescent light source generates a large amount of radiant heat, which limits the application of plastic optical materials very close to the light source.


What is a Fresnel Lens?

Usually, the Fresnel lens is cut into a spherical surface shape in order to minimize the optical aberration of the image during imaging. The lens can better align an ideal point light source into a parallel light source.

In real life, no light source is a real point light source, but solid state light emitters such as LEDs are very small, so as long as the distance between the lens and the LED is appropriate, it can be used as a point light source. Therefore, the lens produced by Yutai can align the LED output light to parallel light, while the traditional incandescent light source generates a lot of radiant heat, which limits the application of plastic optical materials very close to the light source. Since most of the heat generated by the LED is conductive, plastic optical lenses can be easily applied. When the beam source of the LED luminous body needs to be calibrated to a wider angle range.

The most common approach is to use a combination of mirrors and Fresnel lenses to reduce the amount of optical components used. The lens is used for LED light distribution, which can increase the light efficiency and improve the brightness. Compared with the same lens and LED lamp, the focal length is different, the distance is different, the angle of the emitted light can be set arbitrarily, single lamp or multiple array LED lamps can be designed according to requirements. It has been widely used in LED floodlights, colorful floodlights, illuminating lights, landscape lights, signal lights and various lamps.

Features of Fresnel lenses produced by E-Tay

1. Using high-precision original molds, the products have high precision and good quality.

2. The product has an ultra-thin structure, an ultra-large size, and an ultra-light weight.

3. The shape of the product can be cut arbitrarily to meet the subtle differences between different customers and different products.

Conclusion:

Comparing with the traditional lens, the Fresnel lens has the advantages of large area, light weight, lower price, light weight and easy to carry. It is a very widely used optical element. Its design and manufacture involve many technical fields, including optics. Engineering, polymer material engineering, CNC machining, diamond turning process, nickel plating process; molding, injection, casting and other manufacturing processes.

Therefore, the design, development and production of large-scale, high-precision Fresnel lenses have become the main direction of technological development in domestic and foreign production departments. In addition to condensing light, the lens with a lens has a feature that the light source is very evenly distributed, not where the light is strong in some places, and the light is weak in some places. The light of a car without a lens is scattered, and the light source is difficult to control.
