Advantages of using Fresnel lenses for LED lights

LEDs are small in size, but most of the LED cup lenses sold on the market have a thickness of more than 10mm, which has become a fatal problem for LED applications in some occasions, although Fresnel lenses can be used to reduce the thickness of the lens and reduce light absorption . However, the precise ultra-thin zigzag shape can achieve precise optical design, with good optical quality and high light utilization. The serrated lens has a wider range of adaptability, that is, it can adapt to the needs of different use conditions and different processing conditions. Yuying can design the size of the LED lens according to the needs of customers, and the light output angle can be adjusted to reduce the cost of mold opening. Precision machine tool processing, to achieve accurate transmission of light. This kind of sawtooth lens is suitable for secondary optical lens with LED as the light source. For a small light source such as an LED, it is very meaningful to have a small and thin optical lens. The method of zooming and zooming while moving the zigzag lens along the light direction can achieve higher efficiency. Very good results can be obtained for LED light sources with small light source dimensions.
