[0002] Lighting fixtures are widely used in multiple fields such as home lighting, commercial lighting, industrial lighting, road lighting, landscape lighting, and special lighting. After a long period of development, people have higher and higher requirements for the performance of lighting fixtures, which brings greater challenges to the structural design of lighting fixtures.

[0003] In a lighting fixture using a traditional optical scheme, there is light directly emitted from the light-emitting body. If this part of the light enters the human eye, it will cause a glare problem, which will in turn lead to an uncomfortable experience for the user. Therefore, existing lighting fixtures have the problem of poor user experience. Summary of the Invention

[0004] The present invention discloses a light source system and a lighting fixture for a lighting fixture, which can solve the problem of poor user experience existing in lighting fixtures.

[0005] To solve the above problems, the present invention adopts the following technical solutions:

The first reflector is at least partially sleeved inside the second reflector. The first reflector includes a first end and a second end. The first end is provided with a first light outlet, and the first light outlet is located inside the second reflector. The second reflector includes a third end and a fourth end, and the third end is provided with a second light outlet;

[0007] The light-emitting body is arranged inside the second reflector. The second reflector has a first reflecting surface facing the light-emitting body. In the optical axis direction of the light-emitting body, the orthographic projection of the first reflecting surface covers the orthographic projection of the light-emitting body;

[0008] The light emitted by the light-emitting body exits from the second light outlet after passing through at least one of the first reflector and the second reflector.

[0009] A lighting fixture includes the above light source system.

[0010] The technical solutions adopted by the present invention can achieve the following beneficial effects:

[0011] The light source system disclosed in the embodiments of the present invention improves the structure of the light source system of the lighting fixture in the related art, so that the light source system of the lighting fixture includes a first reflector and a second reflector. At the same time, on the optical axis direction of the light-emitting body, the orthographic projection of the first reflecting surface of the second reflector covers the orthographic projection of the light-emitting body. Finally, it can make the light-emitting body blocked by the second reflector. When the light source system of the lighting fixture disclosed in the embodiments of the present invention can project light normally, the light-emitting body can be hidden. Finally, it is difficult for the user to see the light-emitting body through the second light outlet, and thus the purpose of better anti-glare can be achieved, thereby improving the user experience when the user uses the lighting fixture.

[0020] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0021] The technical solutions disclosed in each embodiment of the present invention will be described in detail below with reference to the drawings.

[0022] As Figure 1 and Figure 2 shown, an embodiment of the present invention discloses a light source system of a lighting fixture. The disclosed light source system includes a light emitting body 100, a first reflector 200, and a second reflector 300.

[0023] The light emitting body 100 is a light emitting device of the light source system. The light emitting body 100 can generally be an LED light emitting body. The LED light emitting body has the advantages of high brightness, low heat generation, low energy consumption, and long service life. In the embodiment of the present invention, the light emitting body 100 is disposed within the second reflector 300. Specifically, at least a part of the light emitting body 100 is disposed within the second reflector 300. Specifically, the light emitting body 100 can be entirely disposed within the second reflector 300, which is conducive to more light emitted by the light emitting body 100 being reflected by the second reflector 300.

[0024] Both the first reflector 200 and the second reflector 300 are reflection devices of the light source system, and both can reflect the light emitted by the light emitting body 100. The first reflector 200 is at least partially sleeved within 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 within 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 can be located within the second reflector 300 or outside the second reflector 300.

[0025] The second reflector 300 includes a third end 340 and a fourth end 350. A second light outlet 341 is formed at the third end 340 of the second reflector 300, 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 reflection surface 310 facing the light emitting body 100. In the optical axis direction of the light emitting body 100, the orthographic projection of the first reflection surface 310 covers the orthographic projection of the light emitting body 100. Thus, when observing at a position directly opposite the second light outlet 341, due to the occlusion of the first reflection surface 310, the user cannot see the light emitting body 100.

[0026] The light emitted by the light-emitting body 100 can pass through at least one of the first reflector 200 and the second reflector 300 and then be emitted from the second light-emitting port 341, finally realizing the illumination of the lighting fixture. As Figure 1 shown, a part of the light emitted by the light-emitting body 100 can pass through the first reflecting surface 310 and the first reflector 200 in sequence and then be projected from the second light-emitting port 341. Another part of the light emitted by the light-emitting body 100 can be reflected by the second reflector 300 and then be projected from the second light-emitting port 341. Specifically, by designing the structures of the first reflector 200 and the second reflector 300, it can be ensured that there is no part of the light emitted by the light-emitting body 100 that is directly emitted without being reflected by the first reflector 200 and the second reflector 300.

[0027] The light source system disclosed in the embodiments of the present invention improves the structure of the light source system of the lighting fixture in the related art, so that the light source system of the lighting fixture includes a first reflector 200 and a second reflector 300. At the same time, on the optical axis direction of the light-emitting body 100, the orthographic projection of the first reflecting surface 310 of the second reflector 300 covers the orthographic projection of the light-emitting body 100. Finally, it can be ensured that the light-emitting body 100 is blocked by the second reflector 300. When the light source system of the lighting fixture disclosed in the embodiments of the present invention can project light normally, the light-emitting body 100 is hidden. Finally, it is difficult for the user to see the light-emitting body 100 through the second light-emitting port 341, and thus the purpose of better anti-glare can be achieved, thereby improving the user experience when the user uses the lighting fixture.

[0028] In the embodiments of the present invention, the structure of the first reflector 200 can be various. In an alternative solution, in the first direction, the cross-sectional area of the first reflector 200 decreases. It should be noted that the first direction here refers to the direction in which the first light-emitting port 221 extends towards the second light-emitting port 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 gradually decreases, so that on the basis of ensuring the reflection effect, it can be ensured that more light can be directly projected onto the second reflector 300, and finally be directly projected from the second light-emitting port 341 by the second reflector 300. This structure is more beneficial to shortening the optical path in the process of emitting part of the light, and thus can reduce the energy loss of the light. Of course, the first reflector 200 can also be other structures, as long as it can ensure that the light projected onto it can be reflected to the second light-emitting port 341 and then be projected from the second light-emitting port 341 or can be reflected to the second reflector 300 and then be reflected by the second reflector 300 to the second light-emitting port 341. The embodiments of the present invention do not limit the specific shape of the first reflector 200.

[0029] Similarly, the structure of the second reflector 300 can be various. Please refer to againFigure 1 In an alternative solution, the second reflector 300 may include a first reflecting portion 320 and a second reflecting portion 330 connected to the first reflecting portion 320. The first reflecting portion 320 and the second reflecting portion 330 are arranged in sequence along the aforementioned first direction. In the first direction, the cross-sectional area of the first reflecting portion 320 decreases, and the cross-sectional area of the second reflecting portion 330 increases. The light-emitting body 100 may be disposed within the first reflecting portion 320. The first reflecting portion 320 is provided with the aforementioned first reflecting surface 310. The second light-emitting opening 341 is formed at an end of the second reflecting portion 330 facing away from the first reflecting portion 320. Such a structure is more likely to form an occlusion structure, thereby achieving occlusion of the light-emitting body 100.

[0030] In a further technical solution, the light-emitting body 100 may be disposed within an end of the first reflecting portion 320 facing away from the second reflecting portion 330. Such a structure makes the light-emitting body 100 closer to the fourth end 350 of the second reflector 300, and thus it is more convenient to arrange the light-emitting body 100. At the same time, the fourth end 350 of the second reflector 300 is farther away from the second light-emitting opening 341, and it is easier to achieve occlusion of the light-emitting body 100. Further, the light-emitting body 100 may be configured to be adjacent to an edge of the first reflecting portion 320, such that an end of the first reflecting portion 320 connected to the second reflecting portion 330 is closer to the optical axis of the light-emitting body 100 relative to the light-emitting body 100. At this time, more portions of the first reflecting portion 320 can occlude the light-emitting body 100, and thus it is more beneficial for the first reflecting surface 310 to occlude the light-emitting body 100.

[0031] Specifically, the first reflecting portion 320 and the second reflecting portion 330 may be an integral structure, or may be fixedly connected by assembly. The embodiments of the present invention do not limit the specific fixing manner of the first reflecting portion 320 and the second reflecting portion 330.

[0032] As described above, at least a part of the first reflector 200 is sleeved within the second reflector 300. In an alternative solution, the first end 220 of the first reflector 200 may be located within the second reflecting portion 330. At this time, the size of the first reflector 200 is larger, so that the light emitted by the light-emitting body 100 can be better reflected into the second reflecting portion 330, and finally the second reflecting portion 330 then reflects the light out from the second light-emitting opening 341.

[0033] In an alternative solution, the cross-sectional area of an end of the first reflecting portion 320 connected to the second reflecting portion 330 is a first area, and the cross-sectional area of the other end of the first reflecting portion 320 is a second area. The ratio between the first area and the second area may be 0.6 to 0.9. Such a structure can ensure that the degree of taper of the first reflecting portion 320 is not too large to affect the light output of the light source system, and at the same time can implement good occlusion of the light-emitting body 100.

[0034] In order to ensure that the light emitted by the light-emitting body 100 can be reliably reflected, within the cross-section parallel to the first direction described above, the included angle α between the connection line between the first light-emitting port 221 and the second light-emitting port 341 and the first direction is less than or equal to 45°. Such a setting can make the second light-emitting port 341 converge as much as possible relative to the first light-emitting port 221. Even if the light emitted by the light-emitting body 100 is not reflected by the first reflector 200, it will be reflected by the second reflector 300, thereby improving the light efficiency of the light source system.

[0035] As described above, the first reflector 200 functions as a reflector. The first reflector 200 may have a second reflecting surface 210 facing the light-emitting body 100. The second reflecting surface 210 may be a conical surface. In an alternative solution, the second reflecting surface 210 may be an arc surface. The second reflecting surface 210 may be curved toward the side away from the light-emitting body 100. Such a structure can increase the area of the second reflecting surface 210, and more light can reach the second reflecting surface 210 and then be reflected by the second reflecting surface 210. At the same time, the second reflecting surface 210 can reflect more light to the second reflector 300, thereby making the light homogenizing effect of the entire light source system better.

[0036] In a specific implementation manner, the second end 230 of the first reflector 200 may be located outside the second reflector 300, so as to avoid the problem that the first reflector 200 is entirely located inside the second reflector 300, resulting in a large occupation of the internal space of the second reflector 300, and thus being more conducive to reflecting light.

[0037] In the embodiments of the present invention, the number of the light-emitting bodies 100 may be one or at least two. In an alternative solution, in order to improve the illumination intensity, the number of the light-emitting bodies 100 may be at least two. The light-emitting bodies 100 are arranged along the circumferential direction of the second reflector 300, and finally a ring-shaped light-emitting structure can be formed to achieve a uniform light-emitting effect in multiple directions.

[0038] In a further technical solution, the light source system disclosed in the embodiments of the present invention may further include at least one light distribution member 400. The light distribution member 400 covers the outside of the light-emitting body 100. The light distribution member 400 can perform light distribution on the light emitted by the light-emitting body 100. The light distribution member 400 may be a light homogenizing device or a light condensing device. The embodiments of the present invention do not limit the specific type of the light distribution member 400.

[0039] In an optional scheme, the number of the above-mentioned light distribution components 400 can be one or at least two. The light distribution component 400 can only cover a part of the light-emitting body 100. However, in order to avoid mutual interference, the number of light distribution components 400 is equal to the number of light-emitting bodies 100, and each light distribution component 400 is covered on a light-emitting body 100. That is to say, each light-emitting body 100 is separately configured with a light distribution component 400 for its separate light distribution. The light distribution component 400 is covered on the outside of the light-emitting body 100, thereby alleviating the optical interference between the light-emitting bodies 100, and at the same time, it can also improve the light distribution effect of each light-emitting body 100, so that the light efficiency of the entire light source system is better.

[0040] In a preferred solution, the plurality of light distribution components 400 may be an integrated structure. During the assembly process, the plurality of light distribution components 400 are assembled as a whole without the need for individual installation, thereby facilitating assembly and improving assembly efficiency.

[0041] In other embodiments, the light distribution component 400 may also be a ring-shaped component, and the same light distribution component 400 covers multiple light-emitting bodies 100 arranged along the same circumferential direction. This embodiment can reduce the number of light distribution components 400, thereby facilitating rapid assembly of the light source system.

[0042] Optionally, the light distribution member 400 may be a lens, specifically a convex lens, a concave lens, or a lens group. The lens has a good light distribution effect and a relatively simple structure. In a further technical solution, the light distribution member 400 may be a plano-convex lens, or a cover-shaped lens with a receiving space. Specifically, the light emitter 100 may be located within the receiving space. In this case, the light distribution member 400 can not only play a light distribution role, but also play a role in protecting the light emitter 100.

[0043] In the embodiment of the present invention, the fourth end 350 of the second reflector 300 is an open end. Specifically, in the light source system disclosed in the embodiment of the present invention, the port of the fourth end 350 of the second reflector 300 can be blocked with a circuit board 500, and the light emitting body 100 can be fixed on the circuit board 500, and the circuit board 500 provides an installation position for the light emitting body 100. Specifically, the light emitting body 100 can be electrically connected to the circuit board 500, and then powered by the circuit board 500.

[0044] In a further technical solution, the circuit board 500 can be fixedly connected to the second reflector 300. During the assembly process of the entire lighting fixture, the second reflector 300 can be assembled with the circuit board 500 as the installation basis. At the same time, the circuit board 500 can also block the port of the fourth end 350 of the second reflector 300, thereby preventing the light emitted by the light emitting body 100 from leaking from the port of the fourth end 350 of the second reflector 300.

[0045] In a further technical solution, a heat dissipation base is provided on the side of the circuit board 500 facing away from the light emitter 100, and the heat dissipation base can play a role in heat dissipation. The heat dissipation base can be made of a material with high heat dissipation efficiency. For example, the heat dissipation base can be a stainless steel heat dissipation base or an aluminum heat dissipation base. Alternatively, the heat dissipation base can be designed as a mechanism that is relatively easy to dissipate heat. For example, the heat dissipation base includes a plurality of heat dissipation pins or heat dissipation fins arranged in an array.

[0046] The heat dissipation base can be directly bonded and fixed to the circuit board 500 through a heat-conducting adhesive layer. In this case, the heat generated by the circuit board 500 and the light emitter 100 provided thereon during operation can be quickly transmitted to the heat dissipation base through the heat-conducting adhesive layer, and finally transmitted to the entire lighting fixture through the heat dissipation base, achieving the purpose of rapid heat dissipation.

[0047] Based on the light source system disclosed in the embodiments of the present invention, the embodiments of the present invention also disclose a lighting fixture, and the disclosed lighting fixture includes the light source system described in the above embodiments.

[0048] The lighting fixture disclosed in the embodiments of the present invention can be a downlight, a spotlight, etc., and the embodiments of the present invention do not limit the specific types of the lighting fixture.

[0049] In an alternative solution, the lighting fixture disclosed in the embodiments of the present invention may further include a circuit board 500 and a housing 600. The light emitter 100 is disposed on the circuit board 500, and the circuit board 500 is disposed on the bottom wall 630 of the housing 600, thereby improving the installation strength of the circuit board 500. At this time, the light emitter 100 can be located between the side wall 640 of the housing 600 and the first reflector 200; or, the light emitter 100 is located between the second reflector 300 and the first reflector 200. Relatively speaking, when the light emitter 100 is located between the second reflector 300 and the first reflector 200, the second reflector 300 can surround the light emitter 100, thereby better reflecting light.

[0050] Further, the lighting fixture may further include a mask 700. The housing 600 has an inner cavity 610 and an opening 620. The mask 700 is installed at the opening 620, and the mask 700 and the housing 600 enclose an optical cavity. The light source system is disposed in the optical cavity, that is, both the first reflector 200 and the second reflector 300 are disposed in the optical cavity, and the orientation of the first light outlet 221 is the same as the orientation of the opening 620. The light emitted by the light emitter 100 is reflected by the first reflector 200 and the second reflector 300 and then emitted from the mask 700, and the mask 700 can further improve the light homogenization effect of the lighting fixture.

[0051] Optionally, the second reflector 300 can be fixed between the mask 700 and the bottom wall 630 of the housing 600; or, the second reflector 300 can be fixed between the mask 700 and the circuit board 500. Both of these arrangements can better ensure that the light is reflected and then emitted through the mask 700, thereby improving the light effect of the lighting fixture.

[0052] In order to better realize the driving of the light source system, the lighting fixture may include a driver 800 in addition to the circuit board 500, and the driver 800 is disposed on the circuit board 500. Optionally, the driver 800 may be disposed on a side of the circuit board 500 facing the first light outlet 221, or may be disposed on a side of the circuit board 500 facing away from the first light outlet 221, which is not limited in the embodiment of the present invention.

[0053] The above embodiments of the present invention focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0054] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
