When it is necessary to calibrate the beam source of the LED illuminator to a wider range of angles. The most common practice is to use a mirror combined with a Fresnel lens to reduce the amount of optics used. The Fresnel optical lens is a spherical surface shape cut. In order to minimize image optical aberrations during imaging; Fresnel lenses are used for LED light distribution.

In real life, the effect of brightness is improved. However, solid state illuminators such as LEDs are very small. Therefore, as long as the distance between the lens and the LED is appropriate, the Fresnel is different from the same lens and the LED lamp, the focal length is different, and the distance is different. The lens is capable of calibrating the LED output light into parallel light. A single lamp or multiple array LED lights can be designed according to requirements, which limits the application of plastic optical materials very close to the source: most of the heat generated by the LED is conductive. . It has been widely used in LED floodlights, colorful floodlights, lighting, landscape lights, signal lights, and various lamps.

First, the application is usually. The lens is better able to calibrate the ideal point source into a parallel source.

Second, the characteristics can increase the light efficiency. The product has high precision and good quality, while the traditional incandescent light source generates a large amount of radiant heat: the angle of the emitted light can be arbitrarily set. The product has an ultra-thin structure. No light source is a true point source, with an oversized size and a high precision original mold. It is relatively easy to apply a plastic optical lens, and the shape of the product can be arbitrarily cut, and it can be used as a point source. Meet the nuances of different products of different customers,

Third, summary. Ultra-light weight is a widely used optical component. Including optical engineering, diamond turning technology.

Fresnel lenses are compared to conventional lenses. Molding, injection molding, casting and other manufacturing processes, polymer materials engineering, CNC machining, and its design and manufacturing involve many technical fields. Nickel plating process. It has the advantages of large area, light weight, low price, light and easy to carry. Therefore, the design, development and production of large-scale and high-precision Fresnel lenses have become the main direction of technological development at home and abroad.
