Abstract
Description
Technical Field
[0001] This disclosure relates to the technical field of lighting equipment, and in particular to an adjustable light-emitting mechanism and a multi-angle adjustable light-emitting lamp. Background Technology
[0002] Currently, the light emission angle adjustment of lamps mainly adopts mechanical structure adjustment, which adjusts the light emission angle of optical components manually or by motor drive. However, due to the complexity of the transmission between mechanical structures, not only are malfunctions prone to occur, but they also require a large amount of space, resulting in high production costs and large size of lamps. In order to simplify the structure of lamps and reduce production costs, intelligent industrial and mining lamps, such as the one provided in Chinese patent document CN109764276A, use different groups of LEDs to make the light form different light emission angles through corresponding lens groups. However, due to the structural limitations of the lens group, the light emission angle of the above-mentioned intelligent industrial and mining lamp can only present a preset value. This results in a limited range of adjustment for the light emission angle. If multiple different light emission angles need to be adjusted, multiple lenses with different light emission angles need to be added, which will further increase the production cost and size of the lamp. Utility Model Content
[0003] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an adjustable light emission mechanism and a multi-angle light emission lamp that can more flexibly adjust the light emission angle.
[0004] The purpose of this disclosure is achieved through the following technical solution:
[0005] An adjustable light emission mechanism includes at least two light sources and at least two optical elements; each light source is correspondingly disposed with one of the optical elements; light emitted from each light source enters the corresponding optical element and exits through the corresponding optical element at a corresponding split-lens beam angle; when light emitted from at least any two light sources enters the corresponding optical element, each light passes through the corresponding optical element and together forms light that exits at a combined-lens beam angle; each light source is configured to emit light with varying brightness so that the combined-lens beam angle is different from each of the split-lens beam angles.
[0006] In some embodiments, the beam angles of any two of the split-lens are unequal.
[0007] In some embodiments, the split-beam angle of the optics is 4 to 60 degrees.
[0008] In some embodiments, the light emission angle of one of the optical elements is greater than or equal to 4 degrees and less than 8 degrees, and the light emission angle of the other optical element is greater than or equal to 8 degrees and less than 13 degrees; or,
[0009] One of the optical components has a light emission angle greater than or equal to 13 degrees and less than 20 degrees, and the other optical component has a light emission angle greater than or equal to 20 degrees and less than 29 degrees; or,
[0010] The light emission angle of one of the optical components is greater than or equal to 29 degrees and less than 42 degrees, and the light emission angle of the other optical component is greater than or equal to 42 degrees and less than 60 degrees.
[0011] In some embodiments, the light emission angles of different optical elements differ by 4 to 8 degrees.
[0012] In some embodiments, the maximum spacing between the two light sources is 90 mm.
[0013] In some embodiments, the adjustable light emission angle light emission mechanism further includes an intelligent driver, which is electrically connected to the light source with the same light emission angle via the same line.
[0014] In some embodiments, each of the light sources includes a plurality of light-emitting elements;
[0015] Each optical element includes multiple lenses, and multiple light-emitting elements are arranged in a one-to-one correspondence with multiple lenses. Light emitted by any number of light-emitting elements of each light source element enters the corresponding lens and exits through the corresponding lens at the corresponding split beam angle.
[0016] When light emitted by any number of light-emitting elements of at least any two of the light sources enters the corresponding lens, each light beam passes through the corresponding lens to form a beam emitted at a combined beam angle; each light-emitting element of each of the light sources is configured to emit light with varying brightness so that the combined beam angle is different from each of the separate beam angles.
[0017] In some embodiments, a plurality of light-emitting elements of any two light sources are arranged coaxially in a circular pattern; and,
[0018] The plurality of light-emitting elements of any two light sources are arranged in a circular pattern, with each light-emitting element of each light source being staggered from each light-emitting element of the other light source; or,
[0019] Multiple light-emitting elements of any two light sources are arranged in a circular array, with each light-emitting element of each light source element offset from each light-emitting element of the other light source element; or,
[0020] The plurality of light-emitting elements of any two light sources are arranged in a circular array, and the plurality of light-emitting elements of each light source are evenly arranged, with each light-emitting element of each light source being staggered from each light-emitting element of the other light source; or,
[0021] In each of the aforementioned light sources, a plurality of light-emitting elements are arranged circumferentially, wherein the circumferential radius of the plurality of light-emitting elements of one light source is different from the circumferential radius of the plurality of light-emitting elements of another light source; or,
[0022] The plurality of light-emitting elements of each light source are arranged in a circular array, wherein the circumferential arrangement radius of the plurality of light-emitting elements of one light source is different from the circumferential arrangement radius of the plurality of light-emitting elements of another light source.
[0023] A multi-angle light-emitting lamp includes a light-emitting mechanism with an adjustable light-emitting angle according to any of the above embodiments.
[0024] Compared with the prior art, this disclosure has at least the following advantages:
[0025] The aforementioned adjustable light-emitting angle mechanism, where each light source is paired with a corresponding optical element, allows light emitted from each source to pass through and exit at a specific beam angle after entering the corresponding optical element. At this point, light emitted from at least two source elements, after passing through their respective optical elements, combines to form a beam that exits at a combined beam angle. Compared to existing technologies, by configuring each source element to emit light with varying brightness, the brightness of the light emitted from at least two corresponding source elements can be adjusted, resulting in different combined beam angles and individual beam angles. This allows for more flexible adjustment of the light-emitting angle without requiring additional source or optical elements, making it easier to use. Attached Figure Description

[0032] To facilitate understanding of this disclosure, a more complete description will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the present disclosure. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.
[0033] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0035] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0036] Please see Figure 1 An embodiment of the adjustable light emission angle light emission mechanism includes at least two light source elements 100 and at least two optical elements 200; each light source element 100 is respectively disposed corresponding to one optical element 200; the light emitted by each light source element 100 enters the corresponding optical element 200 and exits through the corresponding optical element 200 at the corresponding split beam angle; when the light emitted by at least any two light source elements 100 enters the corresponding optical element 200, each light passes through the corresponding optical element 200 and together forms the light emitted at the combined beam angle; each light source element 100 is configured to emit light with varying brightness so that the combined beam angle is different from the beam angle of each split beam.
[0037] It is understandable that, since each light source 100 is respectively configured to correspond to an optical element 200, the light emitted by each light source 100, after entering the corresponding optical element 200, can exit through the corresponding optical element 200 at the corresponding split-lens beam angle. At this time, the light emitted by at least any two light sources 100, after passing through the corresponding optical elements 200, jointly form the light that exits at the combined-lens beam angle. Compared with the prior art, by configuring each light source 100 to emit light with varying brightness, the brightness of the light emitted by at least any two corresponding light sources 100 can be adjusted, thereby making the combined-lens beam angle and the beam angle of each split-lens different. This allows for more flexible adjustment of the light emission angle without increasing the types of light sources 100 or optical elements 200, making it easier to use.
[0038] In some embodiments, the split-lens beam angle is the light emission angle of the light emitted by each of the light sources 100 when it is fully lit and passes through its corresponding optical element 200. The light emission angles of the light emitted by the corresponding optical element 200 when the light sources 100 are fully lit are different. That is, it is the light emission angle of the light emitted by the optical element 200 when the brightness percentage of the light source 100 is 1. The number of optical elements 200 and corresponding light sources 100 is at least two. That is, the combined-lens beam angle is the light emission angle of the light emitted by the corresponding optical element 200 when some of the light sources 100 are not fully lit and they pass through the light source 100 when they are not fully lit. In other words, the combined-lens beam angle is the light emission angle obtained by overlapping the light emitted by the corresponding optical element when the brightness percentage of at least one light source 100 is less than 1 and the light emitted by the corresponding optical element of another at least one light source 100 when it passes through the ... For ease of understanding, for example, when there are two groups of optical components 200 and corresponding light source components 100, the light emitted from the first optical component when the first light source component is fully lit has an emission angle of 6 degrees, and the light emitted from the second optical component when the second light source component is fully lit has an emission angle of 10 degrees. By reducing the brightness of the second light source component, the emission angle of the light emitted from the second optical component and the light emitted from the first optical component 200 after overlapping is 8 degrees.
[0039] Please see Figure 1 In some embodiments, the beam angles of any two mirrors are unequal. It is understood that because the beam angles of any two mirrors are unequal, the beam angles of the light emitted from the light source 100 through different optical elements 200 are different. Thus, each light source can emit at least two different beam angles through its corresponding optical element 200. These at least two different beam angles can combine to form light emitted with a combined beam angle. Furthermore, by adjusting the brightness of the light emitted from the corresponding two light sources 100, the combined beam angle can be made different from the beam angles of each mirror, allowing for more flexible adjustment of the emitted light angle.
[0040] Please see Figure 1 In some embodiments, the split beam angle of the optical element 200 is 4 to 60 degrees. It is understood that because the split beam angle of the optical element 200 is 4 to 60 degrees, light passing through optical elements 200 having at least two different exit angles between 4 and 60 degrees collectively simulates light emitted at a combined beam angle. Specifically, optical elements 200 with different exit angles between 4 and 60 degrees can form light emitted at a combined beam angle, that is, a lamp with a light effect intermediate between two different light effects is obtained through two different light effects.
[0041] Please see Figure 1 In this embodiment, the light emission angle of the optical component 200 is selected from at least two intervals among: greater than or equal to 4 degrees and less than 8 degrees, greater than or equal to 8 degrees and less than 13 degrees, greater than or equal to 13 degrees and less than 20 degrees, greater than or equal to 20 degrees and less than 29 degrees, greater than or equal to 29 degrees and less than 42 degrees, and greater than or equal to 42 degrees and less than 60 degrees, and is not limited to the following selection methods:
[0042] In one embodiment, one optical element 200 has a light emission angle greater than or equal to 4 degrees and less than 8 degrees, while the other optical element 200 has a light emission angle greater than or equal to 8 degrees and less than 13 degrees. It can be understood that when one optical element 200 has a light emission angle greater than or equal to 4 degrees and less than 8 degrees, and the other optical element 200 has a light emission angle greater than or equal to 8 degrees and less than 13 degrees, the light emission effect of an optical element 200 with a light emission angle near 8 degrees can be simulated using these two optical elements 200. For example, if one optical element 200 has a light emission angle of 6 degrees and the other optical element 200 has a light emission angle of 10 degrees, the light emission effect of an optical element 200 with a light emission angle of 8 degrees can be simulated using these two optical elements 200 and by adjusting the brightness of the corresponding light source 100.
[0043] In another embodiment, one optical element 200 has a light emission angle greater than or equal to 13 degrees and less than 20 degrees, while the other optical element 200 has a light emission angle greater than or equal to 20 degrees and less than 29 degrees. It can be understood that when one optical element 200 has a light emission angle greater than or equal to 13 degrees and less than 20 degrees, and the other optical element 200 has a light emission angle greater than or equal to 20 degrees and less than 29 degrees, the light emission effect of an optical element 200 with a light emission angle around 20 degrees can be simulated using these two optical elements 200. For example, if one optical element 200 has a light emission angle of 16 degrees and the other optical element 200 has a light emission angle of 24 degrees, the light emission effect of an optical element 200 with a light emission angle of 20 degrees can be simulated using these two optical elements 200 and by adjusting the brightness of the corresponding light source 100.
[0044] In other embodiments, one optical element 200 has a light emission angle greater than or equal to 29 degrees and less than 42 degrees, while the other optical element 200 has a light emission angle greater than or equal to 42 degrees and less than 60 degrees. It can be understood that when one optical element 200 has a light emission angle greater than or equal to 29 degrees and less than 42 degrees, and the other optical element 200 has a light emission angle greater than or equal to 42 degrees and less than 60 degrees, the two optical elements 200 can simulate the light emission effect of an optical element 200 with a light emission angle near 42 degrees. For example, if one optical element 200 has a light emission angle of 41 degrees and the other optical element 200 has a light emission angle of 47 degrees, the two optical elements 200 and the adjustment of the brightness of the corresponding light source 100 can simulate the light emission effect of an optical element 200 with a light emission angle of 44 degrees.
[0045] In some embodiments, the light emission angles of different optical elements 200 differ by 4 to 8 degrees. It is understood that by making the light emission angles of different optical elements 200 differ by 4 to 8 degrees, an appropriate gap can be maintained between the light emission angles of the different optical elements 200, so that the light with the predetermined beam angle can be obtained more quickly by subsequently adjusting the brightness of the corresponding light source 100, while ensuring the adjustable range of the beam angle. Specifically, the light emission angles of different optical elements 200 differ by 4, 6, or 8 degrees; this is merely an example and not intended to limit the scope of this disclosure.
[0046] Please see Figure 1 In this embodiment, the optical component 200 is a lens, and the light emission angle of the lens is different, such as 6 degrees, 8 degrees, 10 degrees, 15 degrees, 24 degrees, 35 degrees, and 60 degrees. Lenses with the same light emission angle are grouped together. The light emission effect of a lens with an emission angle located between two adjacent lenses with different light emission angles can be simulated by lighting the light source component 100 corresponding to two adjacent lenses with different light emission angles. For example, by controlling the light source component 100 corresponding to the lens with a light emission angle of 6 degrees and the light source component 100 corresponding to the lens with a light emission angle of 10 degrees, the light emission effect of a lens with a light emission angle of 8 degrees can be obtained. In this embodiment, all lenses are integrally connected to form a sheet structure, and the light source component 100 is an LED.
[0047] In some embodiments, the maximum distance between the two light source elements 100 is 90 mm. It can be understood that since the maximum distance between the two light source elements 100 is 90 mm, that is, the distance between any two light source elements 100 is less than or equal to 90 mm, the light emitted by any two light source elements 100 can at least partially overlap to form light emitted at the beam angle of the combined mirror.
[0048] Please see Figure 1In some embodiments, the adjustable light emission angle light emission mechanism further includes a smart driver 300, which is electrically connected to the light source elements 100 with the same light emission angle via the same line. It can be understood that because the smart driver 300 is electrically connected to the light source elements 100 with the same light emission angle via the same line, the brightness of each light source element 100 with the same light emission angle can be adjusted by the smart driver 300, thereby making the combined beam angle different from the split beam angle, to achieve more flexible adjustment of the light emission angle. Specifically, the smart driver 300 is a variable resistor, capable of changing the voltage of each line to adjust the brightness of the light source element 100, and even its on / off state.
[0049] Please see Figure 1 and Figure 2 In this embodiment, the adjustable light emission angle light emission mechanism further includes a light source plate 400, on which each light source element 100 is mounted. Light source elements 100 with the same light emission angle are connected to the same circuit on the light source plate 400. The intelligent driver 300 is electrically connected to each circuit on the light source plate 400. For example, the light source elements 100 may include three different light source elements 100. The intelligent driver 300 can electrically enable two or more light source elements 100 to light up simultaneously. Then, by adjusting the brightness of the lit light source elements 100, light projected at the combined beam angle is obtained.
[0050] In some embodiments, each light source 100 includes a plurality of light-emitting elements; each optical element 200 includes a plurality of lenses, with the plurality of light-emitting elements and the plurality of lenses arranged in a one-to-one correspondence; light emitted by any number of light-emitting elements of each light source 100 enters the corresponding lens and exits through the corresponding lens at the corresponding split beam angle; when light emitted by any number of light-emitting elements of at least two light source elements 100 enters the corresponding lens, each light passes through the corresponding lens and together forms light that exits at the combined beam angle; each light-emitting element of each light source 100 is configured to emit light with varying brightness so that the combined beam angle and each split beam angle are different. It is understandable that, since each light-emitting element in each optical component 200 is respectively configured to correspond one-to-one with each lens, the light emitted by any number of light-emitting elements in each light source 100 can pass through the corresponding lens and exit with the corresponding split beam angle after entering the corresponding lens. At this time, the light emitted by any number of light-emitting elements in at least two light source components 100 together forms the light that exits with the combined beam angle after passing through the corresponding lens. Furthermore, by configuring each light-emitting element of each light source 100 to emit light with varying brightness, the brightness of the light emitted by any number of light-emitting elements in at least two corresponding light source components 100 can be adjusted, thereby making the combined beam angle different from each split beam angle. This allows for more flexible adjustment of the light output angle without increasing the types of light source components 100 or optical components 200, making it easier to use.
[0051] It should be noted that, in specific embodiments, the multiple light-emitting elements can be two or more light-emitting elements, specifically two, three, four, etc. Furthermore, the number of light-emitting elements in different light source elements 100 can be the same or different. This is merely illustrative and not intended to limit the specific embodiments. Those skilled in the art can determine the number of light-emitting elements as needed. Also, any number of light-emitting elements in specific embodiments can be at least one, two, more than two, or all. In some embodiments, light emitted by different numbers of light-emitting elements from different light source elements 100 enters the corresponding lens; alternatively, light emitted by the same number of light-emitting elements from different light source elements 100 enters the corresponding lens. Again, this is merely illustrative and not intended to limit the specific embodiments.
[0052] To achieve the effect of focused lighting, the arrangement of multiple light-emitting elements between any two light sources 100 is not limited to the following:
[0053] In one embodiment, multiple light-emitting elements of any two light sources 100 are arranged coaxially in a circular pattern. It can be understood that after the multiple light-emitting elements of any two light sources 100 are arranged coaxially in a circular pattern, the light energy emitted by each light source 100 is evenly distributed, so that the light energy emitted by any number of light-emitting elements of at least any two light sources 100 that are misaligned can more easily form light emitted at a combined beam angle after passing through the corresponding lens.
[0054] In another embodiment, multiple light-emitting elements of any two light sources 100 are arranged in a circular pattern, with each light-emitting element of each light source 100 offset from each light-emitting element of the other light source 100. It can be understood that after the multiple light-emitting elements of any two light sources 100 are arranged in a circular pattern, the light emitted by any number of offset light-emitting elements of at least two light sources 100 can more easily combine into light emitted at a combined beam angle after passing through the corresponding lens.
[0055] In another embodiment, multiple light-emitting elements of any two light sources 100 are arranged in a circular array, with each light-emitting element of each light source 100 offset from each light-emitting element of the other light source 100. It can be understood that after the multiple light-emitting elements of any two light sources 100 are arranged in a circular array, the light emitted by any number of offset light-emitting elements from at least two light sources 100 can form light emitted at a combined beam angle after passing through corresponding lenses, and the luminous efficacy of the light emitted at the combined beam angle at each position is uniform.
[0056] In another embodiment, the plurality of light-emitting elements of any two light sources 100 are arranged in a circular array, and the plurality of light-emitting elements of each light source 100 are evenly arranged, with each light-emitting element of each light source 100 being offset from each light-emitting element of the other light source 100. It can be understood that after the plurality of light-emitting elements of any two light sources 100 are arranged in a circular array and the plurality of light-emitting elements of each light source 100 are evenly arranged, the light emitted by any number of offset light-emitting elements of at least any two light sources 100 can form light emitted at a combined beam angle after passing through the corresponding lens, and the luminous efficacy of the light emitted at the combined beam angle at each position is uniform.
[0057] In other embodiments, the plurality of light-emitting elements of each light source 100 are arranged circumferentially, and the circumferential radius of the plurality of light-emitting elements of one light source 100 is different from the circumferential radius of the plurality of light-emitting elements of another light source 100. It can be understood that by making the circumferential radius of the plurality of light-emitting elements of one light source 100 different from the circumferential radius of the plurality of light-emitting elements of another light source 100—for example, the circumferential radius of the plurality of light-emitting elements of one light source 100 is larger than the circumferential radius of the plurality of light-emitting elements of another light source 100—the plurality of light-emitting elements of different light source 100 can be staggered and concentrically arranged, making the light emitted by each light source 100 more concentrated, thereby achieving the effect of focused lighting.
[0058] In one embodiment, the plurality of light-emitting elements of each light source 100 are arranged in a circular array, with the circumferential radius of the plurality of light-emitting elements of one light source 100 being different from that of the plurality of light-emitting elements of another light source 100. It can be understood that by making the circumferential radius of the plurality of light-emitting elements of one light source 100 different from that of another light source 100—for example, the circumferential radius of the plurality of light-emitting elements of one light source 100 being smaller than that of the plurality of light-emitting elements of another light source 100—the plurality of light-emitting elements of different light source 100s can be staggered and concentrically arranged, making the light emitted by each light source 100 more concentrated, thereby achieving the effect of focused lighting. Simultaneously, because the plurality of light-emitting elements of each light source 100 are arranged in a circular array, the light distribution emitted by each light source 100 is more uniform.
[0059] It should be noted that when there are multiple light source elements 100, the arrangement of the multiple light-emitting elements of the different light source elements 100 can coexist in the same embodiment, and the specifics will not be elaborated here. In this embodiment, the light-emitting element is an LED bead.
[0060] Please see Figure 1 and Figure 3In this embodiment, the light emission angle adjustable light emission mechanism also includes a heat sink 500, which is installed on the back of the light source board 400 to dissipate heat for each light source component 100.
[0061] In some embodiments, the light source 100 includes at least two types of light emitters, and any two light emitters have different light emission angles. It is understood that because the light source 100 includes at least two types of light emitters, and any two light emitters have different light emission angles, the beam angles of the light emitted by the light source 100, which has different types of light emitters, through the optical element 200 are different. Thus, each light source can emit at least two types of light with different beam angles through the corresponding optical element 200. These at least two types of light with different beam angles can combine to form light emitted at a combined beam angle. Furthermore, by adjusting the brightness of the light emitted by at least any two corresponding light source elements 100, the combined beam angle can be made different from the split beam angle, allowing for more flexible adjustment of the light emission angle. The light emitters can be LED beads or projection light sources; however, this is not limited to these types, and those skilled in the art can make other selections as needed.
[0062] Please see Figure 2 In some embodiments, light source elements 100 with the same light emission angle form a group, and corresponding pairs of light source elements 100 within the same group are symmetrically distributed, with each group of light source elements 100 sharing the same center of symmetry. It can be understood that because corresponding pairs of light source elements 100 within the same group are symmetrically distributed, and each group of light source elements 100 shares the same center of symmetry, the light emitted by the light source elements 100 is more concentrated, thereby achieving the effect of focused lighting. Specifically, pairs of light source elements 100 within the same group are centrally symmetrically distributed, and each group of light source elements 100 is arranged in a ring around the same center of symmetry. In this embodiment, light source elements 100 with a first light emission angle form a first light source group 101, light source elements 100 with a second light emission angle form a second light source group 102, and light source elements 100 with a third light emission angle form a third light source group 103.
[0063] Please see Figures 1 to 3This disclosure also provides a multi-angle light-emitting lamp, including the light-emitting angle adjustable light-emitting mechanism of any of the above embodiments. It can be understood that by applying the light-emitting angle adjustable light-emitting mechanism of this disclosure to a multi-angle light-emitting lamp, since each light source 100 is respectively configured to correspond to an optical element 200, the light emitted by each light source 100, after entering the corresponding optical element 200, can pass through the corresponding optical element 200 and exit at the corresponding split-lens beam angle. At this time, the light emitted by at least any two light source elements 100, after passing through the corresponding optical element 200, jointly forms light that exits at the combined-lens beam angle. Compared with the prior art, by configuring each light source 100 to emit light with varying brightness, the brightness of the light emitted by at least any two corresponding light source elements 100 can be adjusted, thereby making the combined-lens beam angle different from each split-lens beam angle, to achieve more flexible adjustment of the light-emitting angle, without increasing the types of light source elements 100 or optical elements 200, making it easier to use.
[0064] Compared with the prior art, this disclosure has at least the following advantages:
[0065] The aforementioned adjustable light-emitting angle light-emitting mechanism, where each light source 100 is correspondingly paired with an optical element 200, allows light emitted from each light source 100 to pass through its corresponding optical element 200 and exit at a corresponding split-lens beam angle. At this point, light emitted from at least two light sources 100, after passing through their respective optical elements 200, collectively forms light emitted at a combined-lens beam angle. Compared to existing technologies, by configuring each light source 100 to emit light with varying brightness, the brightness of the light emitted from at least two corresponding light sources 100 can be adjusted, thereby making the combined-lens beam angle different from each split-lens beam angle. This allows for more flexible adjustment of the light-emitting angle without requiring additional types of light sources 100 or optical elements 200, making it easier to use.
[0066] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
