[0024] Specifically, such as Figure 3 As shown, a light source bracket 5 is also installed inside the heat sink 4, and the light source is fixed inside the heat sink 4 by the light source bracket 5.

[0025] In this embodiment, the lower end of the heat sink 4 is rotatably connected to the lower end of the iron bracket 3, allowing the heat sink 4 to rotate relative to the iron bracket 3. The upper end of the iron bracket 3 is connected to the base plate 2, and the base plate 2 is located inside the lamp tube 1. This allows the heat sink 4 to rotate relative to the lamp tube 1, facilitating the adjustment of the angle between the heat sink 4 and the lamp tube 1.
