The second chamber 13 is in the form of a reflective bowl, the inner wall of the second chamber 13 is provided with a reflective coating, and the light-emitting sheet 11 covers the second chamber 13. Under the action of the second chamber 13, the light irradiated from the second light outlet surface 42 is converted from a scattered state to a focused state, thereby avoiding the problem of glare caused by invalid scattering.

[0035] In an embodiment, in order to facilitate assembly, the lamp shell 10 further comprises an intermediate shell 14 and a rear cover 15, the circuit board 20, the light guide 30 and the lamp head 40 are all snap-fitted on the intermediate shell 14, wherein the light guide 30 and the lamp head 40 are snap-fitted on the intermediate shell 14. The light-emitting sheet 11 is snap-fitted on the front side of the intermediate shell 14, and the rear cover 15 is snap-fitted on the side of the intermediate shell 14 away from the light-emitting sheet 11.

[0036] In an embodiment, the intermediate shell 14 is provided with two support portions 141, each support portion 141 corresponds to one circuit board 20, and each support portion 141 comprises two support columns. Each circuit board 20 is supported on the corresponding two support columns. Specifically, the circuit board 20 is provided with a through hole matched with the support column, and the rear cover 15 is pressed on the circuit board 20.
