DETAILED DESCRIPTION

In order to make objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in a clear and complete way in connection with the specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are just a part but not all of the embodiments of the present application. Based on the described embodiments herein, all other embodiment(s) obtained by those skilled in the art without any inventive work should be within the scope of the present application.
Hereinafter, the technical solutions according to various embodiments of the present application will be described in detail with reference to the accompanying drawings.
Please refer to Fig. 1 and Fig. 2. Embodiments of the present application provide a light source system of a lighting lamp, the light source system includes a first reflector 200 and a second reflector 300.
The first reflector 200 and the second reflector 300 are both reflection devices of the light source system, and each of the first reflector 200 and the second reflector 300 reflects light. In the embodiments of the present application, the first reflector 200 is nested in 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 in 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.
In an optional embodiment, the light source system according to the embodiments of the present application further includes a first luminous body 110, the first luminous body 110 is provided in the first reflector 200, and the first reflector 200 has a first reflection surface 210 facing toward the first luminous body 110. In an optical axis direction of the first luminous body 110, an orthographic projection of the first reflection surface 210 covers an orthographic projection of the first luminous body 110, so that the first reflection surface 210 covers the first luminous body 110, and thus the user cannot see the first luminous body 110 in the case that the user is just opposite to the first light outlet 231. In a specific operation process, light emitted by the first luminous body 110 is reflected by 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 illumination.
In another optional embodiment, as illustrated by Fig. 3, the light source system according to the embodiments of the present application further includes a second luminous body 120, the second luminous body 120 is provided in the second reflector 300, and the second reflector 300 has a second reflection surface 310 facing toward the second luminous body 120. In an optical axis direction of the second luminous body 120, an orthographic projection of the second reflection surface 310 covers an orthographic projection of the second luminous body 120, so that the second reflection surface 310 covers the second luminous body 120, and thus the user cannot see the second luminous body 120 in the case that the user is just opposite to the second light outlet 341. In a specific operation process, light emitted by the second luminous body 120 is reflected by 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 illumination.
The light source system according to the embodiments of the present application for example includes at least one of the first luminous body 110 and the second luminous body 120. In the case that the light source system includes both the first luminous body 110 and the second luminous body 120, the lighting lamp undoubtedly has stronger illumination brightness and better illumination effect. In addition, by designing structures of the first reflector 200 and the second reflector 300, no part of the light emitted by the first luminous body 110 and the second luminous body 120 directly exits without being reflected by the first reflector 200 or the second reflector 300.
The first luminous body 110 and the second luminous body 120 are light emitting devices of the light source system, and the first luminous body 110 and the second luminous body 120 for example are LED luminous bodies, which have the advantages of high brightness, low heat generation amount, low energy consumption and long service life.
According to the light source system in the embodiments of the present application, by improving a structure of the light source system of the lighting lamp in the related art, the light source system of the lighting lamp includes the first reflector 200 and the second reflector 300. In the case that the light source system includes the first luminous body 110, the first luminous body 110 is provided in the first reflector 200, and in the optical axis direction of the first luminous body 110, the orthographic projection of the first reflection surface 210 covers the orthographic projection of the first luminous body 110, so that the first luminous body 110 is shielded by the first reflection surface 210. In the case that the light source system includes the second luminous body 120, the second luminous body 120 is provided in the second reflector 300, and in the optical axis direction of the second luminous body 120, the orthographic projection of the second reflection surface 310 covers the orthographic projection of the second luminous body 120, so that the second luminous body 120 is shielded by the second reflection surface 310. It is thus clear that the light source system of the lighting lamp according to the embodiments of the present application hides the first luminous body 110 and the second luminous body 120 under the condition that the light normally exits, so that it is difficult for users to see the first luminous body 110 and the second luminous body 120, and the purpose of well preventing the glare is achieved.
In the embodiments of the present application, the first reflector 200 has various structures. In an optional solution, an area of a cross section of the first reflector 200 gradually decreases in a first direction. It should be noted that the first direction refers to a direction extending from the first light outlet 231 to the second light outlet 341, and the cross section of the first reflector 200 is perpendicular to the first direction. In this case, an outline size of the first reflector 200 gradually decreases, so that the first luminous body 110 is well shielded by the first reflector 200 on the basis of ensuring the reflection effect of the first reflector 200, and thus the purpose of hiding the first luminous body 110 is achieved. Of course, the first reflector 200 may has other structures, as long as it is ensured that the light projected onto the first reflector 200 is reflected to the second light outlet 341 and then exits from the second light outlet 341 or is reflected to the second reflector 300 and then reflected to the second light outlet 341 by the second reflector 300. The specific shape of the first reflector 200 is not limited in the embodiments of the present application.
Similarly, the second reflector 300 has various structures. Referring to Fig. 1 again, in an optional solution, the second reflector 300 includes a first reflection portion 320 and a second reflection portion 330 connected with the first reflection portion 320. The first reflection portion 320 and the second reflection portion 330 are sequentially provided along the first direction, an area of a cross section of the first reflection portion 320 gradually decreases in the first direction, and an area of a cross section of the second reflection portion 330 gradually increases in the first direction. The second light outlet 341 is provided at an end of the second reflection portion 330 facing away from the first reflection portion 320. This structure easily provides a shielding structure at a connection position of the first reflection portion 320 and the second reflection portion 330, so as to shield the first luminous body 110.
In another specific embodiment, as illustrated by Figs. 4 to 6, the second reflector 300 includes the first reflection portion 320 and the second reflection portion 330 connected with the first reflection portion 320. The first reflection portion 320 is at least partially nested in the second reflection portion 330, the area of the cross section of the first reflection portion 320 gradually decreases in the first direction, and the area of the cross section of the second reflection portion 330 gradually increases in the first direction. Because the area of the cross section of the first reflection portion 320 gradually decreases, a shielding structure is easily provided so as to shield the second luminous body 120. Meanwhile, at least part of the first reflection portion 320 is nested in the second reflection portion 330, so that a length of the second reflector 300 in the first direction becomes smaller, which is beneficial to the miniaturization of the light source system.
In a further technical solution, the first luminous body 110 is provided in the second end 240 of the first reflector 200, which facilitates an arrangement of the first luminous body 110. Meanwhile, a distance between the second end 240 of the first reflector 200 and the first light outlet 231 is greater, then it is more convenient to hide the first luminous body 110. In a further technical solution, the first luminous body 110 is provided to be adjacent to an edge of the first reflector 200, in this case, an end of the first reflection portion 320 connected with the second reflection portion 330 is closer to the optical axis of the first luminous body 110 than the first luminous body 110, so that more parts of the first reflection portion 320 are adopted to shield the first luminous body 110, which is more beneficial to shield the first luminous body 110 by the first reflection surface 210.
In the light source system according to the embodiments of the present application, the second luminous body 120 is provided in an end of the first reflection portion 320 facing away from the second reflection portion 330, that is to say, the second luminous body 120 is provided in the end of the first reflection portion 320 facing away from the second light outlet 341. This structure allows the second luminous body 120 to be closer to the fourth end 350 of the second reflector 300, which facilitates an arrangement of the second luminous body 120. Meanwhile, a distance between the fourth end of the second reflector 300 and the second light outlet 341 is greater, then it is more convenient to shield the second luminous body 120. Furthermore, the second luminous body 120 is provided to be adjacent to an edge of the first reflection portion 320, so that the end of the first reflection portion 320 connected with the second reflection portion 330 is closer to the optical axis of the second luminous body 120 than the second luminous body 120, in this case, more parts of the first reflection portion 320 are adopted to shield the second luminous body 120, which is more beneficial to shield the second luminous body 120 by the second reflection surface 310.
Specifically, the first reflection portion 320 and the second reflection portion 330 are of an integral structure or are fixedly connected with each other by assembling, and the embodiments of the present application do not limit the specific connecting method of the first reflection portion 320 and the second reflection portion 330.
As mentioned above, the first reflector 200 is nested in the second reflector 300. In an optional solution, the first reflector 200 is provided in the first reflection portion 320. This structure ensures that the first reflector 200 is nested in the second reflector 300, and meanwhile, it prevents the first reflector 200 from extending into the second reflection portion 330 so as to avoid adverse effects on the light reflected by the second reflection portion 330.
In a further technical solution, the second end 240 of the first reflector 200 is flush with the end of the first reflection portion 320 facing away from the second light outlet 341. This structure allows that it is easier to install the first reflector 200 and the second reflector 300 on a same installing base (for example, a circuit board 500 described later), and thus the assembly operation of the light source system is simplified.
In an optional solution, an area of a cross section of an end, adjacent to the second light outlet 341, of the first reflection portion 320 is a first area, and an area of a cross section of the other end of the first reflection portion 320 is a second area, and a ratio between the first area and the second area is in a range of 0.6-0.9. This structure prevents a tapering degree of the first reflection portion 320 from being too large to adversely affect the light output of the light source system, and meanwhile, the first luminous body 110 is reliably shielded.
In order to ensure that the light emitted by the first luminous body 110 and the second luminous body 120 are reliably reflected, an included angle α between the first direction and a connection line between the first light outlet 231 and the second light outlet 341 is less than or equal to 45 degrees in the above-described cross section parallel to the first direction. This arrangement allows the second light outlet 341 to shrink relative to the first light outlet 231 as much as possible, and thus even if the light emitted by the first luminous body 110 and the second luminous body 120 is not reflected by the first reflector 200, it is reflected by the second reflector 300, so that the light efficiency of the light source system is improved.
In the embodiments of the present application, an outer circumferential surface of the first reflector 200 is provided with a third reflection surface 220, the third reflection surface 220 is a curved surface, and the third reflection surface 220 is bent toward a side where the second end 240 of the first reflector 200 is located. The third reflection surface 220 reflects the light emitted by the second luminous body 120, so that more light emitted by the second luminous body 120 exits from the light source system, thereby increasing the light output of the light source system. Meanwhile, in the case that the third reflection surface 220 is the curved surface, an area of the third reflection surface 220 is increased, and more light reaches the third reflection surface 220, and then is reflected by the third reflection surface 220. Moreover, the third reflection surface 220 reflects more light to the second reflector 300, so that the light uniformity effect of the whole light source system is better.
In the embodiments of the present application, a total number of each of the first luminous body 110 and the second luminous body 120 is one or at least two. In an optional solution, the total number of the first luminous bodies 110 is at least two, respective first luminous bodies 110 are provided along a circumferential direction of the first reflector 200, and thus an annular luminous structure is formed, so that a uniform luminous effect is achieved in multiple directions.
Similarly, in an optional solution, the total number of the second luminous bodies 120 is at least two, and respective two second luminous bodies 120 are provided along a circumferential direction of the second reflector 300, and thus an annular light emitting structure is formed, so that a uniform luminous effect is achieved in multiple directions.
In a further technical solution, the light source system according to the embodiments of the present application further includes at least one light distribution piece 400, the light distribution piece 400 covers the first luminous body 110 or the second luminous body 120, and the light distribution piece 400 distributes the light emitted by the first luminous body 110 or the second luminous body 120. The light distribution piece 400 is a light-uniformizing device or a light-converging device, and the embodiments of the present application do not limit the specific type of the light distribution piece 400.
In an optional solution, a total number of the light distribution piece 400 is one, or the total number of the light distribution pieces 400 is at least two. The light distribution piece 400 for example covers only a part of the first luminous bodies 110 or a part of the second luminous bodies 120; however, in order to avoid mutual interference, the total number of the light distribution pieces 400 is equal to the total numbers of the first luminous body 110 and the second luminous body 120, and each of the first luminous body 110 and the second luminous body 120 is covered by one light distribution piece 400. That is to say, each first luminous body 110 is individually provided with one light distribution piece 400 for light distribution, and each second luminous body 120 is individually provided with one light distribution piece 400 for light distribution. The light distribution piece 400 covers the first luminous body 110 or the second luminous body 120, so that the optical interference between the first luminous bodies 110 or between the second luminous bodies 120 is alleviated or avoided, and the light distribution effect of each first luminous body 110 or each second luminous body 120 is improved, so that the light efficiency of the whole light source system is more excellent.
In a preferred solution, a plurality of light distribution pieces 400 are of an integral structure. In an assembling process, the plurality of light distribution pieces 400 are installed as a whole without individual installation, thereby facilitating assembling and improving assembling efficiency.
In other embodiments, the light distribution piece 400 is an annular piece, and one light distribution piece 400 covers a plurality of first luminous bodies 110 provided along a same circumferential direction, or one light distribution piece 400 covers a plurality of second luminous bodies 120 provided along a same circumferential direction. This embodiment reduces the total number of the light distribution pieces 400, thereby facilitating the rapid assembling of the light source system.
Optionally, the light distribution piece 400 is a lens, more 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 piece 400 is a plano-convex lens or a cover lens with an accommodating space, and specifically, the first luminous body 110 or the second luminous body 120 is located in the accommodating space. In this case, the light distribution piece 400 not only plays a role of light distribution, but also plays a role of protecting the first luminous body 110 or the second luminous body 120.
In the embodiments of the present application, the fourth end 350 of the second reflector 300 is an open end. Specifically, in the light source system according to the embodiments of the present application, an opening of the fourth end 350 of the second reflector 300 is blocked off by a circuit board 500, the first luminous body 110 and the second luminous body 120 are fixed on the circuit board 500, and the circuit board 500 provides a installing base for the first luminous body 110 and the second luminous body 120. Specifically, the first luminous body 110 and the second luminous body 120 are electrically connected with the circuit board 500, and the circuit board 500 supplies a power to the first luminous body 110 and the second luminous body 120.
In a further technical solution, the circuit board 500 is fixedly connected with the second reflector 300, and in the assembling process of the lighting lamp, the second reflector 300 is installed by using the circuit board 500 as the installing base. Meanwhile, the circuit board 500 further blocks off the opening of the fourth end 350 of the second reflector 300, thereby preventing the light emitted by the first luminous body 110 and the second luminous body 120 from leaking out of the opening of the fourth end 350 of the second reflector 300.
In a further technical solution, a side of the circuit board 500 facing away from the first luminous body 110 or the second luminous body 120 is provided with a heat dissipation seat, and the heat dissipation seat plays a role of heat dissipation. The heat dissipation seat for example is made of a material that is capable of efficiently dissipating heat, such as a stainless steel heat dissipation seat or an aluminum heat dissipation seat. Alternatively, the heat dissipation seat is designed to have a structure that is easy to dissipate heat. For example, the heat dissipation seat includes a plurality of heat dissipation pins or heat dissipation fins distributed in an array.
The heat dissipation seat for example is directly bonded and fixed with the circuit board 500 through a heat-conducting adhesive layer. In this case, the heat generated by the circuit board 500 and the first luminous body 110 or the second luminous body 120 provided on the circuit board 500 in the operation process is quickly transmitted to the heat dissipation seat through the heat-conducting adhesive layer, and then transmitted to the whole lighting lamp through the heat dissipation seat, so as to achieve the purpose of rapid heat dissipation.
Based on the light source system according to the embodiments of the present application, the embodiments of the present application further provide a lighting lamp, and the lighting lamp includes the light source system described in the above embodiments.
The lighting lamp according to the embodiments of the present application for example is a downlight, a spotlight and the like, and the embodiments of the present application do not limit the specific type of the lighting lamp.
In an optional solution, the lighting lamp according to the embodiments of the present application further includes a circuit board 500 and a housing 600, the first luminous body 110 and the second luminous body 120 are provided on the circuit board 500, and the circuit board 500 is provided on a bottom wall 630 of the housing 600, thereby improving the installation stability of the circuit board 500. The first reflector 200 is located between a sidewall 640 of the housing 600 and the first luminous body 110. Or, the first reflector 200 is located between the second reflector 300 and the first luminous body 110. Relatively speaking, in the case that the first reflector 200 is located between the second reflector 300 and the first luminous body 110, the second reflector 300 is more convenient to be installed, that is to say, the second reflector 300 is fixedly connected with the circuit board 500. The second luminous body 120 is located between the sidewall 640 of the housing 600 and the first reflector 200. Or, the second luminous body 120 is located between the second reflector 300 and the first reflector 200. Relatively speaking, in the case that the second luminous body 120 is located between the second reflector 300 and the first reflector 200, the second reflector 300 surrounds the second luminous body 120, so that the second reflector 300 reflects the light better.
Furthermore, the lighting lamp further includes a mask 700. The housing 600 has a chamber 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 chamber. The light source system is provided in the light source chamber, that is to say, both the first reflector 200 and the second reflector 300 are provided in the optical chamber, and an orientation of the first light outlet 231 is consistent with an orientation of the opening 620. The light emitted by the first luminous body 110 and the second luminous body 120 is reflected by the first reflector 200 and the second reflector 300, and then exits from the mask 700, and the mask 700 further improves the light uniformity effect of the lighting lamp.
Optionally, the second reflector 300 is fixed between the mask 700 and the bottom wall 630 of the housing 600; or, the second reflector 300 is fixed between the mask 700 and the circuit board 500. Both of these designs well ensure that the light after being reflected passes through the mask 700 and then exits, so that the illumination effect of the lighting lamp is improved.
In order to better realize the driving of the light source system, the lighting lamp further includes a driver 800 in addition to the circuit board 500, and the driver 800 is provided on the circuit board 500. Optionally, the driver 800 is provided on a side of the circuit board 500 facing the first light outlet 231 or is provided on a side of the circuit board 500 facing away from the first light outlet 231, which is not limited by the embodiments of the present application.
