[0040] In the utility model, the upper cover 30 is arranged on the side of the lamp body 10 facing away from the light source module 20. The upper cover 30 and the lamp body 10 enclose a heat dissipation space 10c. The upper cover 30 is provided with a first heat dissipation hole 30a. The first heat dissipation hole 30a connects the heat dissipation space 10c with the external environment. The first heat dissipation hole 30a is used for allowing cold air from the external environment to enter. Based on the opening design of the upper cover 30, cold air can enter to obtain better heat dissipation performance, so as to improve the heat dissipation effect of the lamp assembly 100, thereby ensuring the service life of the light source module 20.

[0041] Please refer to the attached Figures 3 to 5 At this time, the lamp body 10 is a radiator, and the lamp body 10 is provided with heat dissipation fins 11. The heat dissipation fins 11 are partially covered by the upper cover 30 and are located in the heat dissipation space 10c.

[0042] Among them, there are multiple first heat dissipation holes 30a, and the multiple first heat dissipation holes 30a are arranged at intervals along the annular direction of the upper cover 30, and are connected to the heat dissipation space 10c along different directions.

The mounting bracket 40 avoids the first heat dissipation hole 30a, thereby preventing the mounting bracket 40 from covering the first heat dissipation hole 30a. The lamp assembly 100 is fixed to the wall through the mounting bracket 40, thereby facilitating the installation of the lamp assembly 100.

[0046] Please refer to the attached Figures 2 to 5 In the present invention, the lamp body 10 is provided with a second heat dissipation hole 10b, which is located at one side of the light source module 20 and connects the light source module 20 and the heat dissipation space 10c; the second heat dissipation hole 10b is connected to the first heat dissipation hole 30a through the heat dissipation space 10c, so that the cold air of the external environment enters the heat dissipation space 10c through the first heat dissipation hole 30a and the hot air of the light source module 20 enters the heat dissipation space 10c through the second heat dissipation hole 10b and converges, thereby facilitating the cold air of the external environment to dissipate heat to the light source module 20.
