How does the LED lens show the light control effect?

The ED lens is closely related to the LED, which can enhance the use efficiency and luminous efficiency of light, and can use different lenses to change the optical system of the light field distribution of the LED according to different effects. Let the editor take you to understand how the LED lens shows the light control effect. Welcome to read!

The LED lens is closely linked with the LED to enhance the use efficiency and luminous efficiency of light. It can be used according to different effects. The specifications are penetrating and catadioptric. In the current market, with the rapid change of LED lenses, the optical effects required by different regions and different customers are also very different.

Therefore, the design of LED spotlight lenses faces challenges. How to design LED lenses with high light transmittance, high quality and low cost has become one of the main research fields of LED spotlights. But overall, the focus in the market is on the visualization of the lamps and the overall lighting effect.

The design of the lens must meet three requirements: one is the novelty of the lens shape; the second is the effective light transmittance of the lens; the third is the visual effect of the lens and the lamp.

According to the above three requirements, the common LED lens designs on the market mainly include the following three: the first lens adopts a free-form surface design on its side wall, the low beam surface is the surface of the compound eyeball, and the light-emitting angle can be between 250 and 600 adjust. PC material can be used for COB light source spotlight with large luminous surface diameter of 14mm, and its optical effective transmittance can reach 94%.

The second type of lens uses an external straight face scale and compound eye design in the center of the emitting surface. The third lens adopts an external free-form surface, a low-beam surface and a light-emitting surface with a compound eye surface. The second and third lenses are usually made of PC material with high temperature resistance. The light source can be a SMD light source module or a COB light source. The light output angle is adjustable from 300 to 600, and the light is uniform.

When viewed externally, the modular patch light source can be scattered by the surface of the compound eyeball, and the visual effect is similar to COB, thus expanding the selectivity of the light source.

In addition, considering the high-end market demand and the cost consideration of the luminaire manufacturer, the design of the lens with multiple light sources is also a key point for LED lens designers to pay attention to. Reasonable selection of the compound eye surface and external scale on the spotlight lens can not only make the overall visual effect of the lamp beautiful, but also effectively solve the frequent design problems of different light sources wearing different lenses, saving the development time of lamps.

It can be seen that the design of LED lens has gradually developed in the direction of beauty and generality. How to improve the effective transmittance of directional lighting, spot uniformity and versatility will become the mainstream design.

In various fields of LED lighting, there are indoor lighting, outdoor lighting, commercial engineering lighting, stage lighting, TV backlight, infrared monitoring shop lighting, car lights, etc. Product categories include LED lenses, street light lenses, COB lenses, backlight lenses, infrared lenses, car light lenses, and other optical lenses. The production system of LED lens products including independent design, research and development, manufacturing and molding, helps customers achieve luminous efficacy and lighting effects in various LED lighting fields.
