Description

Technical Field

[0001] The present invention relates to the technical field of lighting, and particularly to a light source system and a lighting fixture for a lighting fixture. Background Art

[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] The lighting fixtures adopting traditional optical schemes have light rays directly emitted from the light-emitting body. If this part of the light rays enters the human eyes, it will cause the problem of glare, and further lead to an uncomfortable experience for users. Therefore, the 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] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] A light source system for a lighting fixture includes a first reflector and a second reflector. The first reflector is sleeved inside the second reflector. A first light outlet is provided at a first end of the first reflector, and the first light outlet is located inside the second reflector. A second light outlet is provided at a third end of the second reflector;

[0007] The light source system further includes a first light-emitting body, and the first light-emitting body is arranged inside the first reflector. The first reflector has a first reflecting surface facing the first light-emitting body. In the optical axis direction of the first light-emitting body, the orthographic projection of the first reflecting surface covers the orthographic projection of the first light-emitting body; and / or,

[0008] The light source system includes a second light-emitting body, and the second light-emitting body is arranged inside the second reflector. The second reflector has a second reflecting surface facing the second light-emitting body. In the optical axis direction of the second light-emitting body, the orthographic projection of the second reflecting surface covers the orthographic projection of the second light-emitting body;

[0009] Wherein, the light rays emitted by the first light-emitting body and the second light-emitting body are emitted from the second light outlet after passing through at least one of the first reflector and the second reflector.

[0010] A lighting fixture includes the above light source system.

[0011] The technical solutions adopted by the present invention can achieve the following beneficial effects:

[0012] The light source system disclosed in the embodiments of the present invention improves the structure of the light source system of a lighting fixture in the related art, so that the light source system of the lighting fixture includes a first reflector and a second reflector. When the light source system includes a first light-emitting body, the first light-emitting body is blocked by the first reflecting surface; when the light source system includes a second light-emitting body, the second light-emitting body is blocked by the second reflecting surface. It can be seen that the light source system of the lighting fixture disclosed in the embodiments of the present invention can hide the first light-emitting body or the second light-emitting body while being able to project light normally, and finally makes it difficult for the user to see the first light-emitting body or the second light-emitting body, thereby achieving a better anti-glare effect and improving the user experience when the user uses the lighting fixture.

[0025] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The technical solutions disclosed in each embodiment of the present invention will be described in detail below in conjunction with the drawings.

[0027] Please refer to Figure 1 and Figure 2 , an embodiment of the present invention discloses a light source system of a lighting fixture, and the disclosed light source system includes a first reflector 200 and a second reflector 300.

[0028] Both the first reflector 200 and the second reflector 300 are reflecting devices of the light source system, and both can reflect light. In the embodiment of the present invention, the first reflector 200 is sleeved inside the second reflector 300. The first reflector 200 includes a first end 230 and a second end 240. The first end 230 is provided with a first light outlet 231, and the first light outlet 231 is located inside the second reflector 300. The second reflector 300 includes a third end 340 and a fourth end 350, and the third end 340 is provided with a second light outlet 341.

[0029] In an optional implementation manner, the light source system disclosed in the embodiment of the present invention may further include a first light emitter 110. The first light emitter 110 is disposed inside the first reflector 200. The first reflector 200 has a first reflecting surface 210 facing the first light emitter 110. In the optical axis direction of the first light emitter 110, the orthographic projection of the first reflecting surface 210 covers the orthographic projection of the first light emitter 110. Furthermore, the first reflecting surface 210 can cover the first light emitter 110, so that when the user faces the first light outlet 231 directly, the first light emitter 110 cannot be observed. In the specific working process, the light emitted by the first light emitter 110 passes through at least one of the first reflector 200 and the second reflector 300 and then exits from the second light outlet 341, thereby achieving the purpose of lighting.

[0030] In another alternative embodiment, as Figure 3 shown, the light source system disclosed in the embodiment of the present invention may further include a second light-emitting body 120. The second light-emitting body 120 is disposed within a second reflector 300. The second reflector 300 has a second reflecting surface 310 facing the second light-emitting body 120. In the optical axis direction of the second light-emitting body 120, the orthographic projection of the second reflecting surface 310 covers the orthographic projection of the second light-emitting body 120. Thus, it can be ensured that the second reflecting surface 310 can cover the second light-emitting body 120, so that when the user faces the second light-emitting port 341 directly, the second light-emitting body 120 cannot be observed. In a specific working process, the light emitted by the second light-emitting body 120 is emitted from the second light-emitting port 341 after passing through at least one of the first reflector 200 and the second reflector 300, thereby achieving the purpose of illumination.

[0031] The light source system disclosed in the embodiment of the present invention may include at least one of a first light-emitting body 110 and a second light-emitting body 120. When the light source system includes both the first light-emitting body 110 and the second light-emitting body 120, the lighting fixture undoubtedly has stronger lighting brightness and achieves a better lighting effect. In addition, 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 first light-emitting body 110 and the second light-emitting body 120 that is directly emitted without being reflected by the first reflector 200 and the second reflector 300.

[0032] The first light-emitting body 110 and the second light-emitting body 120 are light-emitting devices of the light source system. The first light-emitting body 110 and the second light-emitting body 120 are usually LED light-emitting bodies. The LED light-emitting body has the advantages of high brightness, low heat generation, low energy consumption, and long lifespan.

[0033] The light source system disclosed in the embodiments of the present invention improves the structure of the light source system of a lighting fixture in the related art, such that the light source system of the lighting fixture includes a first reflector 200 and a second reflector 300. When the light source system includes a first light-emitting body 110, the first light-emitting body 110 is disposed within the first reflector 200, and in the optical axis direction of the first light-emitting body 110, the orthographic projection of the first reflecting surface 210 covers the orthographic projection of the first light-emitting body 110, so that the first light-emitting body 110 can be blocked by the first reflecting surface 210. When the light source system includes a second light-emitting body 120, the second light-emitting body 120 is disposed within the second reflector 300, and in the optical axis direction of the second light-emitting body 120, the orthographic projection of the second reflecting surface 310 covers the orthographic projection of the second light-emitting body 120, so that the second light-emitting body 120 can be blocked by the second reflecting surface 310. It can be seen that the light source system of the lighting fixture disclosed in the embodiments of the present invention can hide the first light-emitting body 110 or the second light-emitting body 120 while being able to project light normally, ultimately making it difficult for the user to see the first light-emitting body 110 or the second light-emitting body 120, and thus achieving a better anti-glare effect.

[0034] 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 refers to the direction extending from the first light-emitting port 231 to 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, the first light-emitting body 110 can be better blocked, achieving the purpose of hiding the first light-emitting body 110. Of course, the first reflector 200 can also be of other structures, as long as the light projected onto it can be reflected to the second light-emitting port 341 and projected out from the second light-emitting port 341, or can be reflected to the second reflector 300 and then 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.

[0035] Similarly, the structure of the second reflector 300 can be various. Please refer to again Figure 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 a 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 second light-emitting port 341 is opened at an end of the second reflecting portion 330 facing away from the first reflecting portion 320. Such a structure can easily form an occlusion structure at the junction of the first reflecting portion 320 and the second reflecting portion 330, thereby realizing the occlusion of the first light-emitting body 110.

[0036] In another specific embodiment, as Figures 4 to 6 shown, the second reflector 300 includes a first reflecting portion 320 and a second reflecting portion 330 connected to the first reflecting portion 320. At least a part of the first reflecting portion 320 is sleeved inside the second reflecting portion 330. 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. Since the cross-sectional area of the first reflecting portion 320 decreases, it is easier to form an occlusion structure and easier to realize the occlusion of the second light-emitting body 120. At the same time, at least a part of the first reflecting portion 320 is sleeved inside the second reflecting portion 330, so that the length of the second reflector 300 in the first direction can be smaller, which is beneficial to the miniaturization of the component.

[0037] In a further technical solution, the first light-emitting body 110 may be disposed inside the second end 240 of the first reflector 200. Such a structure is more convenient for the layout of the first light-emitting body 110. At the same time, the distance between the second end 240 of the first reflector 200 and the first light-emitting port 231 is greater, which is more conducive to hiding the first light-emitting body 110. In a further technical solution, the first light-emitting body 110 may be configured to be adjacent to the edge of the first reflector 200. In this case, the end of the first reflecting portion 320 connected to the second reflecting portion 330 is closer to the optical axis of the first light-emitting body 110 relative to the first light-emitting body 110. At this time, more parts of the first reflecting portion 320 can occlude the first light-emitting body 110, which is more conducive to the first reflecting surface 210 to occlude the first light-emitting body 110.

[0038] In the light source system disclosed in the embodiments of the present invention, the second light-emitting body 120 may be disposed within one end of the first reflecting portion 320 facing away from the second reflecting portion 330, that is, the second light-emitting body 120 is disposed within one end of the first reflecting portion 320 facing away from the second light-emitting port 341. This structure enables the second light-emitting body 120 to be closer to the fourth end 350 of the second reflector 300, thereby facilitating the layout of the second light-emitting body 120. At the same time, the fourth end of the second reflector 300 is farther from the second light-emitting port 341, making it easier to shield the second light-emitting body 120. Further, the second light-emitting body 120 may be configured to be adjacent to the edge of the first reflecting portion 320, such that one end of the first reflecting portion 320 connected to the second reflecting portion 330 is closer to the optical axis of the second light-emitting body 120 relative to the second light-emitting body 120. At this time, more portions of the first reflecting portion 320 can shield the second light-emitting body 120, which is more conducive to the second reflecting surface 310 shielding the second light-emitting body 120.

[0039] 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.

[0040] As described above, the first reflector 200 is sleeved within the second reflector 300. In an alternative solution, the first reflector 200 may be disposed within the first reflecting portion 320. This structure can ensure that the first reflector 200 is sleeved within the second reflector 300, and at the same time can prevent the first reflector 200 from extending into the second reflecting portion 330, thereby avoiding adverse effects on the light reflected by the second reflecting portion 330.

[0041] In a further technical solution, the second end 240 of the first reflector 200 is flush with one end of the first reflecting portion 320 facing away from the second light-emitting port 341. This structure can more easily mount the first reflector 200 and the second reflector 300 on the same mounting base (such as the circuit board 500 described later), thereby simplifying the assembly operation of the light source system.

[0042] In an alternative solution, the cross-sectional area of one end of the first reflecting portion 320 adjacent to the second light-emitting port 341 is a first area, the cross-sectional area of the other end of the first reflecting portion 320 is a second area, and the ratio between the first area and the second area may be 0.6 to 0.9. This structure can prevent the degree of taper of the first reflecting portion 320 from being too large to affect the light output of the light source system, and at the same time can provide good shielding for the first light-emitting body 110.

[0043] To ensure that the light rays emitted by the first light-emitting body 110 and the second light-emitting body 120 can be reliably reflected, in a cross-section parallel to the aforementioned first direction, the included angle α between the line connecting the first light-emitting port 231 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 231. Even if the light rays emitted by the first light-emitting body 110 and the second light-emitting body 120 are not reflected by the first reflector 200, they will be reflected by the second reflector 300, thereby improving the light efficiency of the light source system.

[0044] In an embodiment of the present invention, a third reflecting surface 220 may be provided on the outer peripheral surface of the first reflector 200. The third reflecting surface 220 may be an arc surface, and the third reflecting surface 220 is curved toward the side where the second end 240 of the first reflector 200 is located. The third reflecting surface 220 can further reflect the light rays emitted by the second light-emitting body 120, so that more of the light rays emitted by the second light-emitting body 120 can be emitted from the light source system, thereby increasing the light output of the light source system. At the same time, when the third reflecting surface 220 is an arc surface, the area of the third reflecting surface 220 increases, and more light rays can reach the third reflecting surface 220 and then be reflected by the third reflecting surface 220. Moreover, the third reflecting surface 220 can reflect more light rays to the second reflector 300, so that the light homogenizing effect of the entire light source system is better.

[0045] In an embodiment of the present invention, the number of the first light-emitting bodies 110 and the second light-emitting bodies 120 may be one, or at least two. In an alternative solution, the number of the first light-emitting bodies 110 may be at least two, and the first light-emitting bodies 110 are arranged along the circumferential direction of the first reflector 200, and finally a ring-shaped light-emitting structure can be formed to achieve a uniform light-emitting effect in multiple directions.

[0046] Similarly, in an alternative solution, the number of the second light-emitting bodies 120 may be at least two, and the second light-emitting bodies 120 may be arranged along the circumferential direction of the second reflector 300, and finally a ring-shaped light-emitting structure can also be formed to achieve a uniform light-emitting effect in multiple directions.

[0047] In a further technical solution, the light source system disclosed in the embodiment of the present invention may further include at least one light distribution member 400. The light distribution member 400 covers the outside of the first light-emitting body 110 or the second light-emitting body 120. The light distribution member 400 can perform light distribution on the light rays emitted by the first light-emitting body 110 or the second light-emitting body 120. The light distribution member 400 may be a light homogenizing device or a light condensing device. The embodiment of the present invention does not limit the specific type of the light distribution member 400.

[0048] In an alternative solution, the number of the light distribution members 400 may be one or at least two. The light distribution member 400 may cover only a part of the first light-emitting bodies 110 or the second light-emitting bodies 120. However, in order to avoid interference between each other, the number of the light distribution members 400 is equal to the total number of the first light-emitting bodies 110 and the second light-emitting bodies 120, and one of the light distribution members 400 is covered outside each of the first light-emitting bodies 110 and each of the second light-emitting bodies 120. That is to say, each of the first light-emitting bodies 110 and each of the second light-emitting bodies 120 is separately provided with a light distribution member 400 for separately distributing light thereto. The light distribution member 400 is covered outside the first light-emitting body 110 or the second light-emitting body 120, so that the optical interference between the first light-emitting bodies 110 or the second light-emitting bodies 120 can be alleviated, and at the same time, the light distribution effect of each of the first light-emitting bodies 110 or the second light-emitting bodies 120 can be improved, making the light efficiency of the entire light source system better.

[0049] In a preferred solution, the multiple light distribution members 400 may be of an integral structure. During the assembly process, the multiple light distribution members 400 are assembled as a whole without individual installation, which can facilitate the assembly and improve the assembly efficiency.

[0050] In other embodiments, the light distribution member 400 is an annular member. The same light distribution member 400 covers a plurality of first light-emitting bodies 110 arranged along the same circumferential direction, or the same light distribution member 400 covers a plurality of second light-emitting bodies 120 arranged along the same circumferential direction. This embodiment can reduce the number of the light distribution members 400, thereby facilitating the rapid assembly of the light source system.

[0051] 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 having an accommodation space. Specifically, the first light-emitting body 110 or the second light-emitting body 120 may be located within the accommodation space. In this case, the light distribution member 400 can not only play a role in light distribution but also play a role in protecting the first light-emitting body 110 or the second light-emitting body 120.

[0052] 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 may be blocked by a circuit board 500. The first light-emitting bodies 110 and the second light-emitting bodies 120 may be fixed on the circuit board 500, and the circuit board 500 provides an installation position for the first light-emitting bodies 110 and the second light-emitting bodies 120. Specifically, the first light-emitting bodies 110 and the second light-emitting bodies 120 may be electrically connected to the circuit board 500 and thus powered by the circuit board 500.

[0053] 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 first light-emitting body 110 and the second light-emitting body 120 from leaking out through the port of the fourth end 350 of the second reflector 300.

[0054] In a further technical solution, a heat dissipation base is provided on the side of the circuit board 500 facing away from the first light-emitting body 110 or the second light-emitting body 120, and the heat dissipation base can play a role in heat dissipation. The heat dissipation base can be made of a material capable of efficiently dissipating heat. 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 into 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.

[0055] The heat dissipation base can be directly bonded and fixed to the circuit board 500 through a thermal conductive adhesive layer. In this case, the heat generated by the circuit board 500 and the first light-emitting body 110 or the second light-emitting body 120 provided thereon during operation can be quickly transmitted to the heat dissipation base through the thermal conductive adhesive layer, and finally transmitted to the entire lighting fixture through the heat dissipation base, achieving the purpose of rapid heat dissipation.

[0056] 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.

[0057] 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.

[0058] In an alternative embodiment, the lighting fixture disclosed in the embodiment of the present invention may further include a circuit board 500 and a housing 600. The first light-emitting element 110 and the second light-emitting element 120 are disposed on the circuit board 500, which is then disposed on the bottom wall 630 of the housing 600, thereby enhancing the mounting strength of the circuit board 500. The first reflector 200 is located between the side wall 640 of the housing 600 and the first light-emitting element 110; alternatively, the first reflector 200 is located between the second reflector 300 and the first light-emitting element 110. Relatively speaking, when the first reflector 200 is located between the second reflector 300 and the first light-emitting element 110, the second reflector 300 is more easily installed, i.e., the second reflector 300 can be fixedly connected to the circuit board 500. The second light-emitting element 120 is located between the side wall 640 of the housing 600 and the first reflector 200; alternatively, the second light-emitting element 120 is located between the second reflector 300 and the first reflector 200. In contrast, when the second light emitting body 120 is located between the second reflector 300 and the first reflector 200 , the second reflector 300 can surround the second light emitting body 120 , thereby better reflecting light.

[0059] Furthermore, 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 mounted at the opening 620. The mask 700 and the housing 600 form an optical cavity. The light source system is disposed in the light source cavity, i.e., the first reflector 200 and the second reflector 300 are both disposed in the optical cavity, and the orientation of the first light outlet 231 is consistent with the orientation of the opening 620. Light emitted by the first light emitter 110 and the second light emitter 120 is reflected by the first reflector 200 and the second reflector 300 and then emitted from the mask 700. The mask 700 can further improve the uniform light effect of the lighting fixture.

[0060] Alternatively, the second reflector 300 may be fixed between the mask 700 and the bottom wall 630 of the housing 600; or, the second reflector 300 may be fixed between the mask 700 and the circuit board 500. Both arrangements can better ensure that light is reflected and then emitted through the mask 700, thereby improving the light efficiency of the lighting fixture.
