How important is the lens to improve light quality? Just look at this downlight.||

Optical devices are an important factor that directly affects the quality of LED downlights, and the impact of lenses on optical performance is even more important. Here is an LED downlight to see how this important optical device improves the light quality. What is a 'lens'? Take this downlight as an example, the crystal clear 'beads' in the mask are lenses, resembling a lotus. Specifically, this is a 'TIR lens'. IF-ICSX series photoelectric LED downlight IF-ICSX series LED downlight lens TIR 'optical conjoined lens' TIR lens is a conical optical device made of special glass, usually axisymmetric design, using total internal transmission and reflection The principle is to ensure that after the light passes through the lens and then reflects out, a beautiful circular spot can be formed. Such a lens can be combined into a plurality of LEDs to become an array lens, or it can exist in the form of a single lens with a bracket. TIR lens optical performance 'control' TIR lens has greater control over the impact of light quality than reflector cups. Because every light emitted from the light source (LED lamp beads) is controlled by the TIR lens to be efficiently used, and a large part of the light does not touch the reflective surface of the reflector, therefore, the advantages and disadvantages of the TIR lens on the optical performance It can be said to play a direct control role. (Large image) The working principle of the lens, the lens with good light reflection path basically has two common points, high light transmittance and strong temperature bearing capacity (after all, LED lamp beads will produce higher temperature during operation). The light transmittance of the lens of this LED downlight by Optoelectronics is as high as ％ or more, and the design matches the LED chip of × mm package. In addition, it can withstand temperatures up to ℃ without fading or degradation, and the optical performance is not affected, which is quite ideal. According to the optical design of this LED downlight, plus the advantages of rotatable multi-angle adjustment function and multiple appearance color choices (mirror, placer gold, and elegant white), it is more suitable for use in hotels, office spaces, commercial places and other areas . In general, it is precisely because of such a high-quality TIR lens, coupled with a one-piece scientific design, that the light effect of this LED downlight can be so excellent, the light is uniform and delicate, the light spot is naturally good, and fully reflects the humanity. The design can make various indoor projects achieve ideal lighting effects. This is exactly the 'secret' of this LED downlight to ensure the uniformity of the indoor lighting environment. Introduction Optoelectronics focuses on lighting design, production and construction, providing overall solutions for LED lighting projects such as airports, hotels, commerce, and offices, and is the designated lighting supplier for major domestic airports. ---Fax contact address: Lighting selection website on the floor of Changhong Science and Technology Building, Science and Technology Park, Nanshan District, Shenzhen
