Referring to FIG. 3 , the support frame 15 includes a bottom plate 151 disposed opposite to each other, a buckle portion 152 , and a connecting portion 153 connecting the buckle portion 152 and the bottom plate 151 . The bottom plate 151 is a long strip-shaped plate, and the number of the latching portions 152 may be plural (for example, two in the embodiment), and the bottom plate 151 may be fixed on the substrate 10 by screws. Keep away from the side of the lamp housing 12. Two grooves 150 are formed on opposite sides of the bottom plate 151 to avoid the locks locked on the substrate 10. The latching portion 152 is parallel to the bottom plate 121, and the connecting portion 153 vertically connects the latching portion 152 and the bottom plate 151. The two connecting portions 153 are respectively adjacent to opposite ends of the bottom plate 151. Each of the latching portions 152 has a rectangular shape, and a central portion of the bottom surface thereof is engaged with the connecting portion 153. The locking portion 152 forms four inclined slopes 156 at four corners of the opposite sides thereof near the bottom surface, and each of the slopes 156 is gradually raised from the inside to the outside, so that the thickness of the buckle portion 152 gradually decreases from the inside to the outside.

The fixing frame 14 includes a top plate 141 and two hooks 142 fixed to the top plate 141. The top plate 141 is substantially a strip-shaped plate member. Each hook 142 includes a first hook 142a and a second hook 142b, and the first hook 142a and the second hook 142b are oppositely disposed. A gap 142c is disposed between the first hook 142a and the second hook 142b. The connecting portion 153 of the support frame 15 is embedded in the gap 142c. The buckle portion 152 is adjacent to one side of the bottom plate 151 and the first hook 142a and the second hook 142b abuts.

Further, the first hook 142a and the second hook 142b are identical in shape and configuration, and each includes a connecting portion 143, a supporting portion 144 and a hook portion 145.
