What should we pay attention to in the selection of LED lens?

People who want to build their own LED light will often need to do a bit of experimenting to determine which types of secondary optics let them achieve their desired light. One important factor to consider is the size of the LED as compared to the optic. For example, if you want a very narrow beam of light, you should choose a larger optic and a smaller emitter. Having a clear understanding of the type of light required will make it significantly easier to choose the appropriate emitter and optics. What should we pay attention to in the selection of LED lens? Let's explain it clearly for you.

Analyze from the use requirements

Application requirements

The application environment of different lamps is different. Considering the lighting effect and normal use in the environment, the matched LED lens must meet its service environment.

LED lens angle requirements

Angle is a relative value. Generally, the beam angle is defined by the trigonometric function relationship between the diameter of the visible spot and the irradiation distance. Adjust according to the design effect.

Customer requirements for light intensity

Some spots are bright in the middle and then attenuate around. Some things become dark at the edge of the spot. There is no clear boundary for the range of the light spot decaying around. Therefore, it is designed or configured according to the actual requirements and standards of customers for light intensity.

Adaptation requirements for light source

Due to the differences in light efficiency and structure of different light sources, such as several major light source brands Kerui, OSRAM, Philips, Riya, etc., the specifications of lenses are also different.

The lens of the module is larger than that of a single one

The distance between the LED light source and the lens will also affect the angle. If it is not a specially designed LED lens, you need to take samples for further test to determine whether it is suitable.

Analyze from the strength of the enterprise

Enterprise qualification

Before purchasing a reassuring LED lens, we should first confirm the qualification of the enterprise. Is it a well-known company in China and what is its qualification? How about users' word of mouth?

Enterprise technology

Why can the enterprise provide and produce a high-performance and high-quality LED lens to users? It is necessary to confirm the resources of the enterprise and whether it has strong technical support, which can generally operate stably for more than ten years.

Enterprise products

Product performance, stable performance, used customer renewal rate of more than 95% of enterprises, product performance will not be poor!

Enterprise product prices

The product price is transparent and free of arbitrary charges. Good ones are afraid of being too expensive and cheap ones are afraid of being bad. Therefore, we should weigh the cost performance of the product. Basically, the price plays a decisive role with the same configuration and performance.

After-sales service

Whether the after-sales service can achieve 7 * 24-hour customer service + technical service, timely and in place service, users will be assured.
