Lenses are widely used, and many things in life use the principle of lenses, such as glasses, cameras, telescopes and so on. The LED lens module ingeniously and closely links the lens with the LED, which enhances the efficiency of light. To change the optical system of the light field distribution of the LED, it can be changed by using different lenses. It truly improves the effect of light and has powerful functions in life.

Material of the lens< strong>There are also different, there are silicone, glass, PC, PMMA, etc. . Different materials have their own advantages and disadvantages, such as PMMA lens, which has the advantages of high production efficiency and high light transmittance, but it also has some inevitable disadvantages. It has certain requirements for temperature and requires The temperature cannot be higher than 80 degrees, otherwise deformation will occur. Although glass lenses are resistant to high temperatures, they are fragile in a single shape and have low production efficiency. In short, materials have their own advantages and disadvantages, and different materials should be selected according to different applications.

According to the application, the LED lens module can also be divided into: Primary Lens, Secondary Lens. The primary lens is integral with the LED and is directly fixed on the LED chip holder. It is mostly made of PMMA, PC, optical glass, and silicone materials. The secondary lens is independent from the LED and cannot be separated during use. The material is generally optical grade PMMA or PC, and glass is used in special cases.

LED lens is an optical accessory and is very precise, There are also strict requirements for accuracy. The processing of such high-precision molds requires ultra-precision processing machines, such as CNC comprehensive processing machines, precision milling machines, drilling machines, interferometers, etc.

LED Lens ModuleProduction also required , it is an optical-grade product and has strict requirements on many aspects, such as light transmittance, refractive index uniformity, refractive index stability, etc., and the appropriate lens material must be selected according to the actual situation. The dust-free workshop is essential, and the staff must also take necessary measures and conduct regular inspections. It must be equipped with a professional optical injection molding machine. To obtain qualified products, the injection molding process must be strictly controlled. The product must not have bubbles, dents, sink marks, flow lines, crescents, etc. The product packaging must be made of dust-proof and anti-static PVC material, so that it is completely sealed. The storage must pay attention to temperature and humidity, and it is best not to store it for more than one year.

The production and design process of the LED lens module is very rigorous< /span> There are many manufacturers in Guangdong, my country, all of which are of good quality. It is a rigorous process from design to production of high-quality LED lenses, and it is necessary to choose a good manufacturer. As for whether it is good or bad, it mainly depends on the light transmittance and anti-glare. You can also understand it with the naked eye: look at the light transmittance, use an obvious color, look through the lens, and choose the one with higher light transmittance. Looking at anti-glare, looking through the lens, the better the anti-glare, the more blurred the edges and corners.
