The end of the bending portion 721 extends downward. The opening of the bending portion 721 gradually becomes larger in the direction from top to bottom, which is conducive to improving the elastic deformation ability of the bending portion 721.

[0082] A shell wall slot 110 is formed on the shell wall 11 of the lamp shell 1 , and the shell wall slot 110 opens downward toward the mounting ring 4 .

[0083] During installation, the bent portion 721 is interference-fitted in the housing wall slot 110 , so that the swinging member 72 and the lamp housing 1 are assembled together.

[0084] In one embodiment, if Figure 5 and Fig. 9 As shown, the end of the bent portion 72 has at least one sawtooth 722, and the sawtooth 722 is at least partially inserted into the shell wall 11. During assembly, the sawtooth 722 eats into the shell wall 11, and the sawtooth 722 acts as a barb to prevent the swing member 72 from escaping from the shell wall slot 110.

[0085] In one embodiment, if Figure 5-Figure 6 and Figure 8 As shown, the shell wall 11 includes a shell wall outer ring 111 and a shell wall inner ring 112 located inside the shell wall outer ring 111 .

The shell wall slot 110 is formed between the shell wall outer ring 111 and the shell wall inner ring 112, the bending portion 721 is interference-fitted between the shell wall outer ring 111 and the shell wall inner ring 112, and the sawtooth 722 is eaten into the shell wall outer ring 111 or the shell wall inner ring 112.

[0089] The inner ring 112 of the shell wall is longer than the outer ring 111 of the shell wall, and the lower end of the inner ring 112 of the shell wall extends out from the lower part of the outer ring 111 of the shell wall. The lower end of the inner ring 112 of the shell wall is in the mounting ring 4, and the upper end of the reflective cup 6 is in the lower part of the inner ring 112 of the shell wall. The light from the light source 2 can be emitted after passing through the lens 3, the inner ring 112 of the shell wall and the reflective cup 6. The lower end of the inner ring 112 of the shell wall is in the mounting ring 4, which plays a light shielding role and prevents light leakage from the side.
