What is anti-glare and why do you choose anti-glare spotlights?

Regarding the "anti-glare (anti-glare)" of LED spotlights, I would like to explain the anti-glare principle to my friends, because when we meet more than 90% decoration friends, we always understand glare as simple non-glare. I can tell you responsibly that there are no spotlights in the market. Whether it is the light directly emitted by LED chips or the light reflected by reflective cups (lenses), people will feel dazzling when they look directly at the lamps. The correct anti-glare means that the side view of the lamp is not dazzling, remember that the side view of the lamp is not dazzling, or it can be said that there is no glare. Then why do many LED lights on the market look dazzling? There are two reasons, 1: the depth of the reflector cup is too shallow, which leads to the LED chip being directly visible to the naked eye, but this situation is generally rare. More often than not, the precision of the reflective cup mold is not high enough, and the electroplated layer (mirror layer) is not smooth enough. The reflective cup principle causes that all light sources will not be reflected by the designed route, and some light sources will randomly reflect, and there will be afterlights entering the eyes, leading to dizziness. Tiandengmeng Lighting has high-quality downlights and provides professional anti-glare design. I use this, the quality is good.
