WHAT IS THE USE OF LED LENS/LENSES? The LED lens is closely related to the LED, which can enhance the use efficiency and luminous efficiency of light, and can be used according to different effects. Specifications are penetrating, catadioptric. They are an affordable and easy-to-use solution for your lighting fitment
WHAT ARE LED LENS MADE OF？ As an optical-grade product, LED lenses have strict requirements on light transmittance, thermal stability, density, refractive index uniformity, refractive index stability, water absorption, turbidity, and maximum long-term operating temperature. Therefore, the material of the lens must be select according to the actual situation. In principle, choose optical grade PMMA, if you have special needs, you can choose optical grade PC
HOW TO CHOOSE A LENS FOR A LED? Look at the transparency of the lens. The use of LED lenses is mainly for lighting, so the problem of light transmission should have a strong ability. If the light transmission is poor, it means that the lighting brightness is not enough, and it is not meaningful to buy an LED lens. Therefore, when choosing a led condenser lens, you can first look at the light transmission performance of the product, and give priority to purchasing with a higher effect.
Look at the service life of the lens. Machines and equipment will definitely age after a period of use, but under normal circumstances the service life is quite long. The same goes for LED lenses. If you buy a good LED lens, even if it is aging, the service life is still very long. Poor quality products may not have a better lifespan.
See the custom price of the lens. There is no unified custom standard for general prices, and there are different prices for the union according to different specifications and materials. Users who have certain budget requirements want to buy LED lenses, they can know the price in advance, and then customize according to their own requirements and the price of the manufacturer, and give priority to the cost-effective products for purchase and use.
NKT LED has many LED module/LED pcb board with lens/lenses, here are some pictures for your reference:
