The first reflector 200 and the second reflector 300 are both reflective devices of the light source system, and both can reflect light emitted from the luminaire 100. The first reflector 200 is at least partially sleeved in the second reflector 300. The first reflector 200 includes a first end 220 and a second end 230, the first end 220 is provided with a first light outlet 221, the first light outlet 221 is located in the second reflector 300, and the light reflected by the first reflector 200 can be emitted from the first light outlet 221. Optionally, the second end 230 of the first reflector 200 may be located inside the second reflector 300, or may be located outside the second reflector 300.
The second reflector 300 includes a third end 340 and a fourth end 350. The third end 340 of the second reflector 300 is opened with a second light outlet 341, and the light reflected by the second reflector 300 can be emitted from the second light outlet 341. The second reflector 300 has a first reflective surface 310 facing the light emitter 100, and in the optical axis direction of the light emitter 100, the orthographic projection of the first reflective surface 310 covers the orthographic projection of the light emitter 100, so that when observing at a position facing the second light outlet 341, a user cannot see the light emitter 100 due to the shielding of the first reflective surface 310.
The light emitted from the light emitter 100 can be emitted from the second light outlet 341 after passing through at least one of the first reflector 200 and the second reflector 300, and finally the illumination of the illumination lamp is realized. As shown in fig. 1, a portion of the light emitted from the light emitter 100 may sequentially pass through the first reflecting surface 310 and the first reflector 200 and then be projected out from the second light outlet 341. Another portion of the light emitted from the light emitter 100 can be reflected by the second reflector 300 and then projected out from the second light outlet 341. Specifically, the first reflector 200 and the second reflector 300 may be configured such that there is no portion of the light emitted from the light emitter 100 that is directly emitted without being reflected by the first reflector 200 and the second reflector 300.

In the embodiment of the present invention, the structure of the first reflector 200 may be various. In an alternative, the area of the cross-section of the first reflector 200 decreases in the first direction. Here, the first direction refers to a direction in which the first light outlet 221 extends toward the second light outlet 341, and the cross section of the first reflector 200 is a section perpendicular to the first direction. In this case, the contour size of the first reflector 200 is gradually reduced, so that it is possible to ensure that a large amount of light is directly projected onto the second reflector 300 while ensuring the reflection function, and finally, is directly projected from the second light outlet 341 by the second reflector 300. The structure is more beneficial to shortening the optical path of part of light in the emitting process, thereby reducing the energy loss of the light. Of course, the first reflector 200 may have other structures as long as it can ensure that the light projected thereon can be projected from the second light outlet 341 after being reflected to the second light outlet 341 or can be reflected to the second reflector 300 and then reflected to the second light outlet 341 by the second reflector 300, and the embodiment of the present invention does not limit the specific shape of the first reflector 200.
Similarly, the structure of the second reflector 300 may be various, please refer to fig. 1 again, and in an alternative scheme, the second reflector 300 may include a first reflection portion 320 and a second reflection portion 330 connected to the first reflection portion 320, the first reflection portion 320 and the second reflection portion 330 are sequentially arranged along the first direction, in the first direction, the cross-sectional area of the first reflection portion 320 decreases progressively, the cross-sectional area of the second reflection portion 330 increases progressively, the light emitter 100 may be disposed in the first reflection portion 320, the first reflection portion 320 is provided with the first reflection surface 310, and the second light outlet 341 is disposed at an end of the second reflection portion 330 away from the first reflection portion 320. Such a structure makes it easier to form a shielding structure, thereby achieving shielding of the light emitter 100.
In a further technical solution, the light emitter 100 may be disposed in an end of the first reflection portion 320 away from the second reflection portion 330, such a structure enables the light emitter 100 to be closer to the fourth end 350 of the second reflector 300, thereby facilitating the arrangement of the light emitter 100; meanwhile, the fourth end 350 of the second reflector 300 is farther away from the second light outlet 341, so that the light emitter 100 is more easily shielded. Furthermore, the light emitter 100 can be disposed adjacent to an edge of the first reflective portion 320, such that an end of the first reflective portion 320 connected to the second reflective portion 330 is closer to an optical axis of the light emitter 100 than the light emitter 100, and at this time, more parts of the first reflective portion 320 can shield the light emitter 100, which is further beneficial for shielding the light emitter 100 by the first reflective surface 310.

In an alternative scheme, a cross-sectional area of one end of the first reflection part 320 connected to the second reflection part 330 is a first area, a cross-sectional area of the other end of the first reflection part 320 is a second area, and a ratio between the first area and the second area may be 0.6-0.9. This structure can prevent the taper degree of the first reflection portion 320 from being too large to affect the light output of the light source system, and can also better shield the light emitter 100.
In order to ensure that the light emitted from the light emitter 100 can be reliably reflected, in a cross section parallel to the first direction, an included angle α between a connecting line between the first light outlet 221 and the second light outlet 341 and the first direction is less than or equal to 45 °. The arrangement makes the second light outlet 341 converge as much as possible with respect to the first light outlet 221, and even if the light emitted from the light emitter 100 is not reflected by the first reflector 200, the light is reflected by the second reflector 300, thereby improving the luminous efficiency of the light source system.
As mentioned above, the first reflector 200 functions as a reflection, the first reflector 200 may have a second reflection surface 210 facing the light emitter 100, and the second reflection surface 210 may be a conical surface, and in an alternative, the second reflection surface 210 may be a curved surface, and the second reflection surface 210 may be curved toward a side away from the light emitter 100, such a structure can increase the area of the second reflection surface 210, so that more light can reach the second reflection surface 210 and then be reflected by the second reflection surface 210. Meanwhile, the second reflecting surface 210 can reflect more light rays to the second reflector 300, so that the light homogenizing effect of the whole light source system is better.
