It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the embodiment of the present application, at least a portion of the light emitter 100 is disposed in the first reflector 200, specifically, the light emitter 100 may be disposed in the first reflector 200, so as to facilitate the light emitted by the light emitter 100 to be reflected more, thereby achieving the purpose of improving the light utilization rate.

The first reflector 200 and the second reflector 300 are both reflection devices of the light source system, and can reflect light emitted from the light emitter 100. The first reflector 200 includes a first end 210 and a second end 220, the first end 210 of the first reflector 200 is provided with a light outlet 211, and light emitted by the light emitter 100 can be finally emitted through the light outlet 211 after being reflected.

At least a part of the second reflector 300 is disposed in the first reflector 200, the second reflector 300 can also reflect the light emitted by the light emitter 100, a projection (orthographic projection) of the light emitter 100 on the light outlet 211 is a first projection, a projection (orthographic projection) of the end of the second reflector 300 facing the light outlet 211 on the light outlet 211 is a second projection, and the second projection covers the first projection. That is, when the light emitter 100 is viewed into the first reflector 200 through the light outlet 211, the light emitter 100 is hidden inside the end of the second reflector 300 facing the light outlet 211, so that the light emitter 100 cannot be viewed by a user, and of course, the light emitted from the light emitter 100 cannot be directly projected from the light outlet 211.

Since the light emitter 100 can be shielded by the second reflector 300 when the light outlet 211 is oriented upward, in the embodiment of the present application, a portion of the light emitted from the light emitter 100 can be projected from the light outlet 211 by the reflection of the second reflector 300 and the first reflector 200 in sequence. Another portion of the light emitted from the light 100 can be projected out of the light outlet 211 by the reflection of the first reflector 200.

It should be noted that the cross section of the first reflector 200 refers to a cross section of the first reflector 200 in a direction perpendicular to the direction of the light outlet 211.

In an alternative, the area of the cross section of the second reflector 300 may increase in the direction of the light outlet 211, and the cross section of the second reflector 300 is the cross section of the second reflector 300 in the direction perpendicular to the direction of the light outlet 211. In this case, the outline size of the end of the second reflector 300 adjacent to the light outlet 211 is larger, so that the light emitter 100 is easier to be shielded.

The second reflector 300 can also be fixed on the circuit board 400, so that the circuit board 400 is used as a mounting base, and in an alternative, the second reflector 300 and the circuit board 400 can be fixedly assembled through the glue layer 1100.
