The light rays in each light emergent region are blocked and limited by the side wall of the light guide hole 555, so that the light emitted by each light emergent region tends to be more direct towards the normal direction of the light emergent surface 550, and the quantity of the light rays irradiated towards the side of the lamp cap 500 is effectively reduced. When a user uses the desk lamp, the light-emitting surface 550 of the lamp cap 500 generally irradiates toward the desk surface. Because the light emitted from the side of the lamp cap 500 is effectively reduced under the action of the honeycomb-shaped light guide holes 555, the light directly irradiated by the light source structure 510 received by eyes of a user can be smoothly reduced, and further, the glare phenomenon of the user can be directly and effectively slowed down or avoided, and further, more comfortable use experience is brought to the user.

In some embodiments, referring to fig. 3, the light source structure 510 includes a plurality of light beads, which are the same as and in one-to-one correspondence with the light guide holes 555. After the light emitted from the lamp beads passes through the light guide hole 555, the light can be emitted from the light emitting surface 550. In this process, the lamp beads and the light guide holes 555 are matched one by one, so that the light emitted from the light emitting surface 550 can be more uniform, and further, the glare generated by a user can be effectively avoided.

Of course, the number of the lamp beads is not necessarily the same as the number of the light guide holes 555, and the number of the lamp beads can be smaller than the number of the light guide holes 555, so that the utilization rate of the lamp beads is effectively improved. Therefore, the number of the light beads and the number of the light guide holes 555 are not unique, but can be adjusted according to the actual situation, and the utility model is not limited herein.

In some embodiments, referring to fig. 3, a lamp panel and a light guide plate 530 are disposed in the lamp cap 500, each of the lamp beads is disposed on the lamp panel, and the light guide plate 530 is located between the lamp panel and the light emitting surface 550.
