[0035] Specifically, the cover plate 1 is used to connect with the installation base surface (such as building ceiling), and the material can be selected from metal or engineering plastic, and the surface can be sprayed to adapt to different decoration styles. A plurality of screw holes are formed in the cover plate 1 for fastening with the building ceiling.

[0036] In the light emitting assembly, the light source component 33 adopts LED light source, and the axis is arranged parallel to the plane of the cover plate 1, and the light source component 33 is fixed in the frame 32 by a support. The reflector 31 is a concave mirror structure, which is arranged at the back of the light source component 33 (i.e. the side away from the light outlet 322), and the central axis of the reflector 31 coincides with the axis of the light source component 33. More preferably, the distance between the two can be adjusted according to the principle of optical reflection to ensure that the light emitted by the light source component 33 can be concentrated to the light outlet 322 after being reflected by the reflector 31. In addition, a cooling fan can be arranged in the frame 32 and located around the light source component 33, and air convection is formed between the cooling fan and the outside through the cooling holes in the cover plate 1 to achieve cooling of the light source component 33.
