When the human eye looks directly at the light outlet of the downlight, glare is generally caused by the brightness difference between the center of the downlight light source 12 and the periphery of the light source 12, resulting in visual fatigue or temporary blindness, and even worse, damage to human vision. Based on the above existing problems, this solution proposes an anti-glare embedded LED downlight. On the basis of providing a light source 12 to the illuminated space on the optical module 1, in order to avoid glare caused by strong light difference to the user when the light source 12 is turned on, an anti-glare part 3 is set at the bottom of the optical component, and its component structure outer ring plate 31 and grid plate 32 are used to block the light source 12, and the overall illumination range is divided into several illumination channels, so as to balance the brightness difference between the center and edge of the light source 12, reduce the direct alignment of the light source 12 to the user's eyes, and enhance the anti-glare effect.

[0027] The described anti-glare embedded LED downlight specifically includes an optical module 1 for providing an illumination light source 12 and diffusing the light source 12.

There is also a heat dissipation module 2 surrounding the optical module 1 and generating a heat evacuation channel to reduce the heat of the optical module 1.

A mounting buckle 5 for abutting against the embedded ceiling is connected through the threaded hole. The end cover 22 is connected to the heat dissipation head 21 to limit the installation of the optical module 1. The end cover 22 is arranged inside the heat dissipation head 21 and works together with the heat dissipation head 21 to clamp the lampshade 11. The end cover 22 is provided with an annular cover body 221 and a connecting ring 222 that protrudes from the cover body and is threadedly connected to the inner wall of the end head 211. A number of heat dissipation holes 223 aligned with the heat dissipation through-holes 213 are provided on the annular cover body 221 outside the connecting ring 222. The inner diameter of the annular cover body 221 is smaller than the inner diameter of the lampshade 11, and the inner diameter of the connecting ring 222 is larger than the outer diameter of the lampshade 11. The light source 12 provides lighting brightness downward at the center position of the annular cover body 221.

[0029] The anti-glare element 3 includes an outer ring plate 31 that determines the installation position and a grid plate 32 disposed within the outer ring plate 31 and dividing the outer ring plate 31 into a plurality of spaces. In this specific embodiment, the outer ring plate 31 is bonded to the inner wall of the diffuser end and is attached to the inner wall of the diffuser end in a ring-shaped manner. The grid is disposed within the outer ring plate 31 and is connected to the inner wall of the outer ring plate 31.
