Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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 invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the embodiment of the present invention discloses a light source system of a lighting fixture, the disclosed light source system includes a light emitter 100, a first reflector 200, and a second reflector 300.
The light emitter 100 is a light emitting device of a light source system, and the light emitter 100 may be an LED light emitter generally, which has advantages of higher brightness, lower heat generation, lower energy consumption, and longer life. In the embodiment of the present invention, the light emitter 100 is disposed in the second reflector 300, specifically, at least a portion of the light emitter 100 is disposed in the second reflector 300, specifically, the light emitter 100 may be disposed in the second reflector 300, so as to facilitate that the light emitted by the light emitter 100 is reflected by the second reflector 300 more.
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.
The light source system disclosed in the embodiment 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 the first reflector 200 and the second reflector 300, and at the same time, in the optical axis direction of the light emitter 100, the orthographic projection of the first reflecting surface 310 of the second reflector 300 covers the orthographic projection of the light emitter 100, and finally the light emitter 100 can be shielded by 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 rays 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.
Specifically, the first reflection portion 320 and the second reflection portion 330 may be an integrated structure, or may be fixedly connected by assembling, and the embodiment of the present invention does not limit the specific fixing manner of the first reflection portion 320 and the second reflection portion 330.
As described above, at least a portion of the first reflector 200 is nested within the second reflector 300. In an alternative scheme, the first end 220 of the first reflector 200 may be located in the second reflection portion 330, and the first reflector 200 is larger in size, so that the light emitted by the light emitter 100 can be better reflected into the second reflection portion 330, and finally the light is reflected by the second reflection portion 330 and then reflected out of the second light outlet 341.
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.
In a specific embodiment, 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 located entirely inside the second reflector 300, which causes a large occupied space inside the second reflector 300, and is more favorable for reflecting light.
In the embodiment of the present invention, the number of the light emitters 100 may be one, or may be at least two. In order to improve the illumination intensity, in an alternative scheme, the number of the light emitters 100 may be at least two, and the light emitters 100 are arranged along the circumferential direction of the second reflector 300, so that an annular light emitting structure can be finally formed, and a multi-directional uniform light emitting effect is realized.
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 is covered outside the light emitter 100, the light distribution member 400 may distribute light emitted by the light emitter 100, the light distribution member 400 may be a light uniformizing device or a light condensing device, and the embodiment of the present invention is not limited to specific types of the light distribution member 400.
In an alternative scheme, the number of the light distribution members 400 may be one or at least two, and only a part of the light emitters 100 may be covered by the light distribution members 400, but in order to avoid mutual interference, the number of the light distribution members 400 is equal to the number of the light emitters 100, and each light distribution member 400 is covered by one light emitter 100, that is, each light emitter 100 is separately provided with one light distribution member 400 for separate light distribution, and the light distribution members 400 are covered by the outside of the light emitters 100, so that the optical interference between the light emitters 100 can be alleviated, and meanwhile, the light distribution effect of each light emitter 100 can be improved, so that the light efficiency of the whole light source system is better.
In a preferred embodiment, the plurality of light distribution members 400 may be a unitary structure. In the assembling process, the plurality of light distribution members 400 are integrally assembled without being installed individually, so that the assembling is convenient and the assembling efficiency is improved.
In other embodiments, the light distribution member 400 may also be an annular member, and the same light distribution member 400 covers a plurality of light emitters 100 arranged along the same circumferential direction, which may reduce the number of light distribution members 400, thereby facilitating the rapid assembly of the light source system.
Optionally, the light distribution member 400 may be a lens, specifically, a convex lens, a concave lens, or a lens group, and 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 may be a hood-shaped lens having an accommodating space, and specifically, the light emitting body 100 may be located in the accommodating space, in which case, the light distribution member 400 not only can perform a light distribution function, but also can perform a function of protecting the light emitting body 100.
In the embodiment of the present invention, the fourth end 350 of the second reflector 300 is an open end, and specifically, in the light source system disclosed in the embodiment of the present invention, the circuit board 500 may be plugged at the port of the fourth end 350 of the second reflector 300, the light emitter 100 may be fixed on the circuit board 500, and the circuit board 500 provides an installation position for the light emitter 100. Specifically, the light emitter 100 may be electrically connected to the circuit board 500, and further powered by the circuit board 500.
In a further aspect, the circuit board 500 may be fixedly connected to the second reflector 300, and the second reflector 300 may be assembled based on the circuit board 500 during the whole assembly process of the lighting fixture. Meanwhile, the circuit board 500 can seal the port of the fourth end 350 of the second reflector 300, so as to prevent the light emitted by the light emitter 100 from leaking out of the port of the fourth end 350 of the second reflector 300.
In a further technical solution, a heat sink is disposed on a side of the circuit board 500 away from the light emitter 100, and the heat sink can perform a heat dissipation function. The heat sink may be made of a material that efficiently dissipates heat, for example, the heat sink may be a stainless steel heat sink, or an aluminum heat sink. Alternatively, the heat sink may be designed to dissipate heat more easily, for example, the heat sink includes a plurality of pins or fins distributed in an array.
The heat sink can be directly bonded and fixed with the circuit board 500 through the heat conducting adhesive layer, under the condition, the heat generated by the circuit board 500 and the luminous body 100 arranged on the circuit board during working can be quickly transmitted to the heat sink through the heat conducting adhesive layer, and finally transmitted to the whole lighting lamp through the heat sink, so that the purpose of quick heat dissipation is achieved.
Based on the light source system disclosed by the embodiment of the invention, the embodiment of the invention also discloses a lighting lamp, and the disclosed lighting lamp comprises the light source system disclosed by the embodiment.
The lighting lamp disclosed by the embodiment of the invention can be a down lamp, a spot lamp and the like, and the embodiment of the invention does not limit the specific types of the lighting lamps.
In an optional scheme, the lighting fixture disclosed in the embodiment 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, so as to improve the mounting strength of the circuit board 500. At this time, the light emitter 100 may be located between the sidewall 640 of the case 600 and the first reflector 200; alternatively, the luminaire 100 is located between the second reflector 300 and the first reflector 200. In contrast, when the light emitter 100 is located between the second reflector 300 and the first reflector 200, the second reflector 300 may surround the light emitter 100, thereby better reflecting light.
Further, the lighting fixture may further include a face shield 700, the housing 600 has an inner cavity 610 and an opening 620, the face shield 700 is mounted at the opening 620, and the face shield 700 and the housing 600 enclose an optical cavity, the light source system is disposed in the light source cavity, that is, the first reflector 200 and the second reflector 300 are both disposed in the optical cavity, and the orientation of the first light outlet 221 coincides with the orientation of the opening 620. The light emitted from the light emitter 100 is reflected by the first reflector 200 and the second reflector 300 and then emitted from the face shield 700, and the face shield 700 can further improve the light-homogenizing effect of the lighting fixture.
Optionally, the second reflector 300 may be secured between the face shield 700 and the bottom wall 630 of the housing 600; alternatively, the second reflector 300 is fixed between the cover 700 and the circuit board 500.
