[0002] LED lights are widely used in all aspects of life. Due to their energy-saving and durable characteristics, they are gradually replacing traditional light sources. In the field of ceiling lights, because they are installed on the ceiling, when multiple ceiling lights are installed on the ceiling in some large spaces, the lights that are far away from people and use mirrored reflectors often produce glare problems.

[0003] Current ceiling downlights reduce glare by retracting the light source as much as possible into the fixture. However, even with the light source retracted deeply, a glaring light can still appear on the reflector, causing discomfort. Utility Model Content
