LED downlight: different reflector material, the light effect is very different! ||

The lens and reflector are the soul of the lamp, especially the latter, whose optical design is the decisive checkpoint for the final realization of the quality of the light. The reflector cups of different materials and structural processes have very different light output effects. Here, the reflectors of various LED downlights are compared, and the black diamond series LED downlights of Optoelectronics are taken as an example for in-depth explanation. The reflector of LED downlight, high temperature resistant PC vacuum aluminum plating, this type of reflector is molded by PC high temperature injection molding, and the appearance is vacuum aluminum electroplated. The light output angle is usually -°. The reflector of this material has a high efficiency (up to %), but the disadvantage is that its anti-glare effect is not good. , Temperature-resistant, high-reflective white PC material, this reflector cup is molded by PC high-temperature injection molding, and the cost is relatively low. The reflector itself transmits light inside the outer surface, and the reflectivity reaches %. But the disadvantage is that the diffusion is too large, and some light will appear uncontrolled. , Aluminum spinning Aluminum spinning, as the name implies, is to perform anodizing or electroplating on the surface after spinning aluminum foil. The manufacturing process of this kind of reflector cup is relatively simple, but it is easy to cause the risk of short circuit. It can be seen that reflectors of different types and materials have different light effects and defects are unavoidable. So, is there a kind of reflector that can learn from each other's strengths? Take a look at the photoelectric black diamond series LED downlights. The black diamond LED downlight has a smooth inner wall reflector + anti-glare face ring to improve luminous flux utilization. In terms of optical design, the black diamond series of LED downlights use a scientific secondary light distribution design, using a reflector + face ring light distribution method. Ensure uniform light output, no macular stray light, and light efficiency greater than lmW. This kind of reflector cup with a smooth inner wall guarantees the multiple reflections of the arc surface. First, the lens forms a penetrating condensing light directly in front, and then the inner wall cooperates with the conical reflector surface to collect and reflect all the side light. The overlap of the two kinds of light can get the ideal light utilization, the light spot is very beautiful, the light is uniform, and there is no yellow halo stray light. From the perspective of anti-glare, the anti-glare face ring adopts a new generation of nano-coating technology, which makes the light output of the black diamond downlight uniform and soft, and at the same time enhances the 'deep anti-glare' function. Through the above detailed comparison, we found that the black diamond LED downlights can 'overtake' other reflector types of lamps in terms of the reflector's light effect, illuminance, or comprehensive lighting cost.
