Description

Technical Field

[0001] This application relates to the technical field of lighting fixtures, and particularly to a lighting fixture and its light source system. 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 poses greater challenges to the structural design of lighting fixtures.

[0003] In lighting fixtures adopting traditional optical schemes, there is light directly emitted from the light-emitting body. If this part of the light enters the human eye, it will cause the problem of glare, and then lead to an uncomfortable experience for users. Therefore, existing lighting fixtures have the problem of poor user experience. Summary of the Invention

[0004] This application discloses a light source system of a lighting fixture, which can solve the problem of relatively serious glare in current lighting fixtures.

[0005] To solve the above problems, this application adopts the following technical solutions:

[0006] A light source system of a lighting fixture includes a first light-emitting body, a second light-emitting body, a first reflector, a second reflector, and a third reflector, wherein:

[0007] Both the second reflector and the third reflector are at least partially disposed within the first reflector. The third reflector is located within the space surrounded by the second reflector. The first reflector includes a first end, and an light-emitting opening is provided at the first end;

[0008] Both the first light-emitting body and the second light-emitting body are at least partially disposed within the first reflector. The first light-emitting body is disposed between the second reflector and the first reflector, and the second light-emitting body is disposed between the second reflector and the third reflector;

[0009] The projection of the end of the second reflector facing the light-emitting opening in the direction of the light-emitting opening is a first projection, the projection of the end of the third reflector facing the light-emitting opening in the direction of the light-emitting opening is a second projection, the projection of the first light-emitting body in the direction of the light-emitting opening is a third projection, and the projection of the second light-emitting body in the direction of the light-emitting opening is a fourth projection. The first projection covers the third projection, and the second projection covers the fourth projection.

[0010] The technical solutions adopted by this application can achieve the following beneficial effects:

[0011] The embodiment of the present application discloses a light source system of a lighting fixture. By improving the lighting fixture in the related art, the light source system of the lighting fixture includes a first reflector, a second reflector, and a third reflector. At the same time, the third projection of the first light-emitting body in the direction of the light outlet can be covered by the first projection of the end of the second reflector facing the light outlet in the direction of the light outlet. Finally, the first light-emitting body can be blocked by the second reflector, and the fourth projection of the second light-emitting body in the direction of the light outlet can be covered by the second projection of the end of the third reflector facing the light outlet in the direction of the light outlet. Finally, the second light-emitting body can be blocked by the third reflector. The light emitted by the first light-emitting body and the second light-emitting body can be reflected by at least one of the first reflector, the second reflector, and the third reflector and then projected from the light outlet. It can be seen that the light source system of the lighting fixture disclosed in the embodiment of the present application can hide the first light-emitting body and the second light-emitting body while being able to project light normally.

[0031] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0032] The technical solutions disclosed in each embodiment of the present application will be described in detail below in conjunction with the drawings.

[0033] Please refer to Figures 1 to 4 , an embodiment of the present application discloses a light source system of a lighting fixture. The disclosed light source system includes a first light emitter 100, a second light emitter 200, a first reflector 300, a second reflector 400, and a third reflector 500.

[0034] Both the first light emitter 100 and the second light emitter 200 are light-emitting devices of the light source system. The first light emitter 100 and the second light emitter 200 can generally be LED light emitters. LED light emitters have the advantages of high brightness, low heat generation, low energy consumption, and long lifespan. In the embodiment of the present application, both the first light emitter 100 and the second light emitter 200 are at least partially disposed within the first reflector 300. In a more preferred solution, both the first light emitter 100 and the second light emitter 200 are completely located within the first reflector 300, so as to ensure that more light emitted by the first light emitter 100 and the second light emitter 200 is reflected and finally projected out.

[0035] The first reflector 300, the second reflector 400, and the third reflector 500 are all reflection components of the light source system, and can all be used to reflect the light emitted by at least one of the first light emitter 100 and the second light emitter 200 to achieve the purpose of light distribution. In the embodiment of the present application, the first reflector 300 is a peripheral structural member of the light source system, at least part of the second reflector 400 and at least part of the third reflector 500 are both disposed within the first reflector 300, and moreover, the third reflector 500 is located within the space surrounded by the second reflector 400.

[0036] As described above, the first reflector 300 is a peripheral structural member of the light source system. The first reflector 300 includes a first end 310 and a second end 320. The first end 310 is provided with a light outlet 311. The light emitted by the first light emitter 100 and the second light emitter 200 can both finally be projected outside the light source system through the light outlet 311, thereby realizing illumination.

[0037] In the embodiment of the present application, the projection (orthogonal projection) of the end of the second reflector 400 facing the light outlet 311 in the direction of the light outlet 311 is the first projection, and the projection (orthogonal projection) of the end of the third reflector 500 facing the light outlet 311 in the direction of the light outlet 311 is the second projection. The first light emitter 100 is disposed between the second reflector 400 and the first reflector 300, and the projection (orthogonal projection) of the first light emitter 100 in the direction of the light outlet 311 is the third projection. The second light emitter 200 is disposed between the second reflector 400 and the third reflector 500, and the projection (orthogonal projection) of the second light emitter 200 in the direction of the light outlet 311 is the fourth projection. The first projection covers the third projection, and the second projection covers the fourth projection.

[0038] The first projection covering the third projection enables the second reflector 400 to cover the first light emitter 100, so that when observing into the first reflector 300 directly facing the light outlet 311, the covered first light emitter 100 cannot be seen; similarly, the second projection covering the fourth projection enables the third reflector 500 to cover the second light emitter 200, so that when observing into the first reflector 300 directly facing the light outlet 311, the covered second light emitter 200 cannot be seen. That is to say, the light emitted by the first light emitter 100 and the second light emitter 200 cannot be directly projected out from the light outlet 311.

[0039] Please refer to Figure 1 , in the specific working process, the light emitted by the second light emitter 200 can be reflected by at least one of the second reflector 400, the third reflector 500, and the first reflector 300, and finally be projected outside the light source system through the light outlet 311. Please refer to Figure 2, in the specific working process, the light emitted by the first light-emitting body 100 can be reflected by at least one of the second reflector 400 and the first reflector 300, and finally projected outside the light source system through the light outlet 311.

[0040] The light source system of the lighting fixture disclosed in the embodiment of the present application improves the lighting fixture in the related art, so that the light source system of the lighting fixture includes a first reflector 300, a second reflector 400, and a third reflector 500. At the same time, the third projection of the first light-emitting body 100 in the orientation of the light outlet 311 can be covered by the first projection of the end portion of the second reflector 400 facing the light outlet 311 in the orientation of the light outlet 311. Finally, the first light-emitting body 100 can be blocked by the second reflector 400, and the fourth projection of the second light-emitting body 200 in the orientation of the light outlet 311 can be covered by the second projection of the end portion of the third reflector 500 facing the light outlet 311 in the orientation of the light outlet 311. Finally, the second light-emitting body 200 can be blocked by the third reflector 500. The light emitted by the first light-emitting body 100 and the second light-emitting body 200 can be reflected by at least one of the first reflector 300, the second reflector 400, and the third reflector 500 and then projected out from the light outlet 311. It can be seen that the light source system of the lighting fixture disclosed in the embodiment of the present application can hide the first light-emitting body 100 and the second light-emitting body 200 when the light can be normally projected, and finally the user cannot see the first light-emitting body 100 and the second light-emitting body 200 through the light outlet 311, so as to achieve a better anti-glare purpose.

[0041] As described above, at least part of the second reflector 400 is disposed inside the first reflector 300. That is to say, the second reflector 400 can be partially disposed inside the first reflector 300 or can be entirely disposed inside the first reflector 300. In a more preferred solution, the second reflector 400 can be entirely disposed inside the first reflector 300, so as to make full use of the internal space of the first reflector 300 for setting, which is beneficial to making the structure of the light source system more compact and occupying less space.

[0042] Similarly, at least part of the third reflector 500 is disposed inside the first reflector 300. That is to say, the third reflector 500 can be partially disposed inside the first reflector 300 or can be entirely disposed inside the first reflector 300. In a more preferred solution, the third reflector 500 can be entirely disposed inside the first reflector 300, so as to make full use of the internal space of the first reflector 300 for setting, which is beneficial to making the structure of the light source system more compact and occupying less space.

[0043] In an embodiment of the present application, the first reflector 300 may have an increasing cross-sectional area in the orientation of the light exit 311, so as to form a light exit 311 with a larger area, which is conducive to more light being projected out, thereby achieving the purpose of improving the light utilization rate.

[0044] In an alternative solution, in the orientation of the light exit 311, the cross-sectional area of the second reflector 400 increases, and the cross-section of the second reflector 400 is the section of the second reflector 400 perpendicular to the orientation direction of the light exit 311. This structure makes it easier for the end of the second reflector 400 facing the light exit 311 to form a structure that blocks the first light-emitting body 100, and at the same time enables the second reflector 400 to form a relatively smooth reflection structure, which is conducive to the light source system forming a more uniform light projection.

[0045] Similarly, in another alternative solution, in the orientation of the light exit 311, the cross-sectional area of the third reflector 500 increases, and the cross-section of the third reflector 500 is the section of the third reflector 500 perpendicular to the orientation direction of the light exit 311. This structure makes it easier for the end of the third reflector 500 facing the light exit 311 to form a structure that blocks the second light-emitting body 200, and at the same time enables the third reflector 500 to form a relatively smooth reflection structure, which is conducive to the light source system forming a more uniform light projection.

[0046] In the light source system disclosed in the embodiment of the present application, at least one of the second reflector 400 and the third reflector 500 may be a solid of revolution, which is convenient for manufacturing, and is conducive to forming reflection regions with small differences, and is conducive to ensuring the light output performance of the light source system. At the same time, the solid-of-revolution structure has the advantage of being convenient for manufacturing.

[0047] The first light-emitting body 100 and the second light-emitting body 200 may be one or multiple. In an alternative solution, when both the second reflector 400 and the third reflector 500 are solids of revolution, both the first light-emitting body 100 and the second light-emitting body 200 may be multiple. Multiple first light-emitting bodies 100 may be arranged around the second reflector 400, and multiple second light-emitting bodies 200 may be arranged around the third reflector 500. This structure enables both the multiple first light-emitting bodies 100 and the multiple second light-emitting bodies 200 to form a ring-shaped light-emitting structure. After the light emitted by the ring-shaped light-emitting structure is reflected, the light finally projected from the light exit 311 is more balanced.

[0048] In order to further improve the light efficiency, in an alternative solution, there may be multiple first light emitters 100. The light source system disclosed in the embodiments of the present application may further include multiple first light distribution devices 700, and each first light distribution device 700 covers one first light emitter 100. Each first light distribution device 700 can perform light distribution on the light emitted by the first light emitter 100. The first light distribution device 700 may be a reflector or a light distribution lens. The embodiments of the present application do not limit the specific type of the first light distribution device 700. The multiple first light distribution devices 700 may be independent monomeric structural members. Of course, the multiple first light distribution devices 700 may be an integral structural member. In this case, the multiple first light distribution devices 700 form an inseparable whole, which is convenient for the light source system to be assembled more efficiently.

[0049] Similarly, in another alternative solution, there may be multiple second light emitters 200. The light source system may further include multiple second light distribution devices 800, and each second light distribution device 800 covers one second light emitter 200. Each second light distribution device 800 can perform light distribution on the light emitted by the second light emitter 200. The second light distribution device 800 may be a reflector or a light distribution lens. The embodiments of the present application do not limit the specific type of the second light distribution device 800. The multiple second light distribution devices 800 may be independent monomeric structural members. Of course, the multiple second light distribution devices 800 may be an integral structural member. In this case, the multiple second light distribution devices 800 form an inseparable whole, which is convenient for the light source system to be assembled more efficiently.

[0050] As described above, there may be various types and structures of the first light distribution device 700 and the second light distribution device 800. For example, the first light distribution device 700 may be a plano-convex lens. In an alternative solution, the first light distribution device 700 may have a first accommodation space 710. Specifically, the first light distribution device 700 may be a cover-shaped structural member. The first light emitter 100 is located within the first accommodation space 710. In this case, the first light distribution device 700 can also protect the first light emitter 100.

[0051] Similarly, the second light distribution device 800 may be a plano-convex lens. In an alternative solution, the second light distribution device 800 may have a second accommodation space 810. Specifically, the second light distribution device 800 may be a cover-shaped structural member. The second light emitter 200 is located within the second accommodation space 810. In this case, the second light distribution device 800 can also protect the second light emitter 200.

[0052] The light source system disclosed in the embodiments of the present application further includes a circuit board 600, and the circuit board 600 seals the port of the second end 320 of the first reflector 300. The circuit board 600 is fixedly connected to the first reflector 300. Both the first light emitter 100 and the second light emitter 200 can be fixed on the circuit board 600. Both the second reflector 400 and the third reflector 500 can be fixed on the circuit board 600. The circuit board 600 can provide an installation base and power supply for the first light emitter 100 and the second light emitter 200, and at the same time can also provide an installation base for the second reflector 400 and the third reflector 500. Moreover, the circuit board 600 seals the port of the second end 320 of the first reflector 300, which can prevent the light emitted by the first light emitter 100 and the second light emitter 200 from emitting out of the port of the second end 320 of the first reflector 300.

[0053] In an alternative embodiment, the circuit board 600, the first light emitter 100 and the second light emitter 200 form a light source board, thereby realizing an integral installation.

[0054] In order to improve the utilization rate of light, in an alternative solution, the circuit board 600 may include a central region 610 and an annular peripheral region 620 arranged around the central region 610. The end of the second reflector 400 facing the light outlet 311 and the end of the third reflector 500 facing the light outlet 311 are both located within the central region 610 in the orthographic projection on the circuit board 600. Both the first light emitter 100 and the second light emitter 200 can be arranged within the central region 610, that is to say, the first light emitter 100 and the second light emitter 200 are arranged outside the annular peripheral region 620. This way of partitioning the circuit board 600 makes the positions where the first light emitter 100 and the second light emitter 200 are installed on the circuit board 600 clearer, which is conducive to the assembly of the first light emitter 100 and the second light emitter 200.

[0055] In a further technical solution, a heat dissipation base 1000 may be provided on the side of the circuit board 600 facing away from the first light emitter 100 or the second light emitter 200, and the heat dissipation base 1000 can play a role in heat dissipation. The heat dissipation base 1000 can be made of a material capable of efficiently dissipating heat. For example, the heat dissipation base 1000 can be a stainless steel heat dissipation base. Alternatively, the heat dissipation base 1000 can be designed into a mechanism that is relatively easy to dissipate heat. For example, the heat dissipation base 1000 includes a plurality of heat dissipation pins arranged in an array.

[0056] The heat dissipation base 1000 can be directly bonded and fixed to the circuit board 600 through a heat-conducting adhesive layer. In this case, the heat generated by the circuit board 600 and the first light-emitting body 100 and the second light-emitting body 200 disposed thereon during operation can be quickly transmitted to the heat dissipation base 1000 through the heat-conducting adhesive layer, and finally transmitted to the entire lighting fixture through the heat dissipation base 1000, achieving the purpose of rapid heat dissipation.

[0057] During the specific working process, the light rays emitted by the first light-emitting body 100 and the second light-emitting body 200 may be projected onto the central region 610 or the annular peripheral region 620 under the reflection of the first reflector 300 or the second reflector 400. In order to improve the utilization rate of light, in an optional solution, at least one of the annular peripheral region 620 and the central region 610 is provided with a reflective layer 900 on the surface facing the light outlet 311. The reflective layer 900 can reflect the light projected onto the annular peripheral region 620 or the central region 610, thereby improving the utilization rate of the light rays.

[0058] At the same time, the annular peripheral region 620 is provided with a reflective layer 900, and the reflective layer 900 can make the annular peripheral region 620 present a bright surface, thereby improving the lighting performance of the light source system.

[0059] In an optional solution, when the second reflector 400 is disposed within the first reflector 300, in the light source system disclosed in the embodiment of the present application, the distance between the second reflector 400 and the end face of the second end 320 of the first reflector 300 can be zero. The distance between the second reflector 400 and the end face of the first end 310 of the first reflector 300 can be greater than zero. In this case, the second reflector 400 and the first light-emitting body 100 can be farther away from the light outlet 311, which is more conducive to achieving a better anti-glare purpose.

[0060] Similarly, when the third reflector 500 is disposed within the first reflector 300, in the light source system disclosed in the embodiment of the present application, the distance between the third reflector 500 and the end face of the second end 320 of the first reflector 300 is zero. The distance between the third reflector 500 and the end face of the first end 310 of the first reflector 300 is greater than zero. In this case, the third reflector 500 and the second light-emitting body 200 can be farther away from the light outlet 311, which is more conducive to achieving a better anti-glare purpose.

[0061] In an alternative solution, the height of the third reflector 500 can be greater than the height of the second reflector 400, so that the third reflector 500 can have a larger area to reflect the light emitted by the second light emitter 200. Moreover, it is also beneficial to reflect the light reflected from other directions again, achieving the purpose of more levels of reflection. It should be noted that the height of the third reflector 500 refers to the distance between the end face of the third reflector 500 facing the light outlet 311 and the end face of the second end 320 of the first reflector 300; the height of the second reflector 400 refers to the distance between the end face of the second reflector 400 facing the light outlet 311 and the end face of the second end 320 of the first reflector 300.

[0063] The lighting fixture disclosed in the embodiments of the present application can be a downlight, a spotlight, a chandelier, etc., and the embodiments of the present application do not limit the specific type of the lighting fixture.

[0064] In an alternative solution, the lighting fixture disclosed in the embodiments of the present application may further include a housing 1100 and a face mask 1200. The housing 1100 has an inner cavity 1110 and an opening 1120. The face mask 1200 is installed at the opening 1120, and the face mask 1200 and the housing 1100 enclose a lamp inner cavity 1130. The light source system is disposed in the lamp inner cavity 1130, and the orientation of the light outlet 311 is the same as the orientation of the opening 1120. The lighting fixture disclosed in the embodiments of the present application further includes a driver 1300. The driver 1300 is disposed on the circuit board 600. Specifically, the driver 1300 can be disposed in the lamp inner cavity 1130.
