Several grid bars 720 can increase the number of reflective surfaces with a large reflective area, which can reflect the light emitted by the LED lamp multiple times, making the light softer, further reducing the glare effect, and having an anti-glare effect, which is beneficial to vision health. For example, the grille 700 is arranged at the light outlet 530 of the reflective cup 500 and covers the light outlet 530 so as to better reflect the light emitted by the LED lamp. For example, a reflective layer (not shown) is provided on the outer surface of the grid bar 720 to better reflect the light emitted by the LED lamp. In addition, the utilization rate of the emitted light from the LED lamp can also be improved. the

For example, the grille 720 of the grille 700 is arranged in the spacer 710 in a honeycomb shape, and the honeycomb-shaped grille 720 can further enhance the diffusion of the light emitted by the LED lamp, making the light emitted by the LED lamp more comfortable and soft.
