[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figures 1 to 3 The embodiment of the utility model proposes a lamp with uniform light emission, including a lamp housing 1, a lamp strip 2 and a diffusion plate 3. The lamp housing 1 is provided with an installation cavity 13, the lamp strip 2 is connected to the side wall of the installation cavity 13, the diffusion plate 3 is arranged inside the ring-surrounded by the lamp strip 2, a plurality of lamp beads 21 are arranged on the lamp strip 2, a plurality of notches 31 are arranged on the diffusion plate 3, the plurality of lamp beads 21 are arranged in a one-to-one correspondence with the plurality of notches 31, the plurality of lamp beads 21 emit light at the same time, thereby realizing multi-point light emission, thereby avoiding the occurrence of light spots in the light emitted by the lamp, and then the light emitted by the lamp beads 21 is diffused by the diffusion plate 3, so that the light emitted by the lamp is more uniform.

[0025] Reference Figure 3 The number of lamp beads 21 and notches 31 is greater than or equal to five, and they are arranged at equal intervals. The light emitted by adjacent lamp beads 21 is used to eliminate the dark shadow area, making the light more uniform, and the notches 31 are in an arc shape to facilitate the light emitted by the lamp beads 21 to enter the interior of the diffuser plate 3 to achieve a diffusion effect.

[0026] Reference Figure 3 The lamp with uniform light emission also includes a reflective paper 4 and a light guide plate 5. The reflective paper 4 and the light guide plate 5 are both arranged in the installation cavity 13. The reflective paper 4 is located between the bottom wall of the installation cavity 13 and the diffuser 3, and the light guide plate 5 is located between the reflective paper 4 and the diffuser 3.

[0027] Reference Figure 2 and Figure 3 The lamp housing 1 includes a lampshade 11 and a lamp cover 12. The lampshade 11 and the lamp cover 12 are combined to form an installation cavity 13. The lampshade 11 and the lamp cover 12 are both circular in shape. The lamp cover 12 is made of a transparent material to facilitate light to pass through. An open cavity 14 is opened at one end of the lampshade 11.
