The mounting seat comprises a base 20 and an upper cover 30, the mounting panel 10 is positioned between the base 20 and the upper cover 30, and the plane of the base 20 and the plane of the upper cover 30 are parallel to each other. Optionally, the upper cover 30 and the base 20 are made of metal, so that the strength is increased, and meanwhile, the heat dissipation can be assisted. The mounting panel 10 is hinged to the mounting seat, and in the embodiment, the mounting panel 10 is hinged to the base 20 through a first hinge 22, and an axial direction of the first hinge 22 is parallel to a plane of the base 20. Of course, the mounting panel 10 may be hinged to the upper cover 30 by the first hinge 22, but the axial direction of the first hinge 22 is also parallel to the plane of the base 20. The upper cover 30 is provided with a light-transmitting through-hole 31, and the light emitted from the light emitting member 11 is irradiated to a corresponding position through the light-transmitting through-hole 31. In practical application, a filter can be disposed on the light-transmitting through hole 31, or a grating can be disposed in front of the light-emitting member 11; of course, a filter may be disposed on the light-transmitting through-hole 31, and a grating may be disposed in front of the light-emitting member 11.
