Description
Technical Field
[0001] This utility model relates to the field of light source device technology, and in particular to a light source arrangement structure and lighting device. Background Technology
[0002] Traditional light source devices generally use a single color temperature or a single light pattern. To achieve multi-light pattern and multi-color temperature lighting functions, the existing conventional method is to integrate two individual light sources that emit different high and low color temperatures, and then control the brightness and projection light pattern of these two individual light sources to control the overall color temperature and projection light pattern of the light emission effect. However, this method of combining individual light sources requires sufficient spacing between each individual light source, which means that the light spot needs to travel a long distance to achieve a natural and uniform effect when projected by the combined individual light sources. If the distance is insufficient, it is easy to cause uneven light spot and affect the user experience. Therefore, how to achieve a light source arrangement structure that can improve the uniformity of the light spot has become an urgent problem to be solved. Summary of the Invention
[0003] The main purpose of this invention is to provide a light source arrangement structure that improves upon the shortcomings of the prior art and solves the problem of poor uniformity of light spots formed by close-range projection of light emitted from the light source device.
[0004] To achieve the above objectives, this utility model proposes a light source arrangement structure, comprising:
[0005] substrate body;
[0006] The substrate body is divided into a first lighting region and a second lighting region along its first central axis of symmetry.
[0007] The first lighting area is provided with n first light sources and m second light sources, and the second lighting area is provided with m first light sources and n second light sources. The arrangement of the n first light sources and m second light sources in the first lighting area is the opposite of the arrangement of the m first light sources and n second light sources in the second lighting area.
[0008] The color temperature of the first light source is either cool white or warm white, and the color temperature of the second light source is either cool white or warm white. n and m are both natural numbers greater than or equal to 1.
[0009] Optionally, along the second central axis of symmetry of the substrate body, the first lighting area and the second lighting area are divided into four lighting zones, the number of first light sources in each lighting zone is equal, and the number of second light sources in each lighting zone is equal, and the second central axis of symmetry and the first central axis of symmetry are perpendicular to each other.
[0010] Optionally, the arrangement of the plurality of first light sources and the plurality of second light sources in the two lighting zones that are symmetrically arranged about the second central axis of symmetry is a mirror image of each other.
[0011] Optionally, the arrangement of the plurality of first light sources and the plurality of second light sources in the two lighting zones that are symmetrically arranged about the second central axis of symmetry is the same.
[0012] Optionally, within any of the aforementioned lighting zones, a plurality of first light sources and a plurality of second light sources are alternately distributed.
[0013] Optionally, the light pattern of the first light source is either a focused light pattern or a floodlight pattern, and the light pattern of the second light source is either a focused light pattern or a floodlight pattern.
[0014] Optionally, within the first lighting area and / or the second lighting area, the center distance between any two adjacent first light sources and second light sources is equal.
[0015] Optionally, the cross-section of the substrate body is rectangular.
[0016] Optionally, within the first lighting area or the second lighting area, a plurality of first light sources and a plurality of second light sources are arranged in a line.
[0017] In addition, this application also provides a lighting device, including the above-described light source arrangement structure.
[0018] Beneficial Effects: The light source arrangement structure proposed in this utility model includes a substrate body, which is divided into a symmetrical first illumination area and a second illumination area along a first central axis of symmetry of the substrate body. The first illumination area contains n first light sources and m second light sources, and the second illumination area contains m first light sources and n second light sources. The arrangement of the n first light sources and m second light sources in the first illumination area is the opposite of the arrangement of the m first light sources and n second light sources in the second illumination area. The color temperature of the first light sources is one of cool white and warm white, and the color temperature of the second light sources is the other of cool white and warm white. n and m are both natural numbers greater than or equal to 1. This design improves the uniformity of the final projected light spot, thereby solving the problem of poor light spot uniformity formed by close-range projection of light emitted from the light source device.

[0030] See Figures 1-3 As shown, the present invention provides a light source arrangement structure including a substrate body 1. The substrate body 1 has a rectangular cross-section and is divided into a first lighting area 12 and a second lighting area 13 along the first central axis of symmetry 11 of the substrate body 1.
[0031] The first lighting area 12 is provided with n first light sources 2 and m second light sources 3, and the second lighting area 13 is provided with m first light sources 2 and n second light sources 3. The arrangement of the n first light sources 2 and m second light sources 3 in the first lighting area 12 is the opposite of the arrangement of the m first light sources 2 and n second light sources 3 in the second lighting area 13.
[0032] Among them, the color temperature of the first light source 2 is one of cool white and warm white, and the color temperature of the second light source 3 is the other of cool white and warm white. n and m are both natural numbers greater than or equal to 1.
[0033] Specifically, see Figure 1As shown, two first light sources 2 and two second light sources 3 are provided in the first lighting area 12, and two first light sources 2 and two second light sources 3 are provided in the second lighting area 13. The two first light sources 2 and two second light sources 3 in the first lighting area 12 are arranged at equal intervals along the extension direction of the first central axis of symmetry 11. Similarly, the two first light sources 2 and two second light sources 3 in the second lighting area 13 are arranged at equal intervals along the extension direction of the first central axis of symmetry 11. The two first light sources 2 in the first lighting area 12 and the two second light sources 3 in the second lighting area 13 are arranged correspondingly, and the two second light sources 3 in the first lighting area 12 and the two first light sources 2 in the second lighting area 13 are arranged correspondingly, so that the arrangement of the two first light sources 2 and two second light sources 3 in the first lighting area 12 is the opposite of the arrangement of the two first light sources 2 and two second light sources 3 in the second lighting area 13.
[0034] See Figure 2 As shown, in one embodiment of this application, a first light source 2 and two second light sources 3 are provided in a first lighting area 12. The first light source 2 and two second light sources 3 in the first lighting area 12 are arranged at equal intervals along the extension direction of the first central axis of symmetry 11. A second lighting area 13 is provided with two first light sources 2 and one second light source 3. The two first light sources 2 and one second light source 3 in the second lighting area 13 are arranged at equal intervals along the extension direction of the first central axis of symmetry 11. The first light source 2 in the first lighting area 12 and the second light source 3 in the second lighting area 13 are correspondingly arranged, and the two second light sources 3 in the first lighting area 12 and the two first light sources 2 in the second lighting area 13 are correspondingly arranged.
[0035] It is worth mentioning that the number of first light sources 2 and second light sources 3 in the first lighting area 12 of the light source arrangement structure provided in this application is not limited to the number of light sources listed above. The number of first light sources 2 and second light sources 3 in the first lighting area 12 can also be 3, 4, 5, 6 or even more. Similarly, the number of first light sources 2 and second light sources 3 in the second lighting area 13 is not limited to the number of light sources listed above. The number of first light sources 2 and second light sources 3 in the second lighting area 13 can be 3, 4, 5, 6 or even more. Those skilled in the art can select the number of first light sources 2 and second light sources 3 according to actual production needs. All equivalent structural transformations made under the inventive concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, should be included within the patent protection scope of this utility model.
[0036] The light source arrangement structure provided in this embodiment of the utility model divides a first illumination region 12 and a second illumination region 13 based on the first central symmetry axis 11 of the substrate body 1. The first illumination region 12 is equipped with n first light sources 2 and m second light sources 3, and the second illumination region 13 is equipped with m first light sources 2 and n second light sources 3. The arrangement of the light sources in the first illumination region 12 is opposite to that in the second illumination region 13, so that the n first light sources 2 in the first illumination region 12 are all staggered from the m first light sources 2 in the second illumination region 13, and the m second light sources 3 in the first illumination region 12 are all staggered from the n second light sources 3 in the second illumination region 13. This design constructs a uniform color temperature interlacing network on the surface of the substrate body 1, and different color temperature light rays form dense intersections on the projection path, which significantly improves the micro-scale light mixing effect and improves the uniformity of the final projected light spot, thereby solving the problem of poor light spot uniformity formed by close-range projection of light emitted by the light source device.
[0037] See Figure 1 and Figure 3 As shown, in one embodiment of this application, along the second central symmetry axis 14 of the substrate body 1, the first lighting area 12 and the second lighting area 13 are divided into four lighting zones 15. The number of first light sources 2 in each lighting zone 15 is equal, and the number of second light sources 3 in each lighting zone 15 is equal. The second central symmetry axis 14 and the first central symmetry axis 11 are perpendicular to each other.
[0038] Specifically, using the mutually perpendicular first central axis of symmetry 11 and second central axis of symmetry 14 as a reference, the surface of the substrate body 1 is divided into four illumination zones 15. The number of first light sources 2 and second light sources 3 in each illumination zone 15 is equal. With this design, even if a single light source has a small luminous flux or directional deviation, when using the above light source arrangement structure, these random errors will show similarity in the four illumination zones 15. During the light spot synthesis process, the errors of different illumination zones 15 cancel each other out, significantly improving the uniformity of the final projected light spot.
[0039] See Figure 1 As shown, in one embodiment of this application, in any lighting zone 15, a plurality of first light sources 2 and a plurality of second light sources 3 are alternately distributed, and the arrangement of the plurality of first light sources 2 and a plurality of second light sources 3 in two lighting zones 15 that are symmetrical about the second central axis of symmetry 14 is a mirror image of each other.
[0040] The first light source 2 and the second light source 3 in the two lighting zones 15, which are symmetrically arranged about the second central axis of symmetry 14, are arranged in a mirror symmetric layout. This design allows the assembly tolerances of each light source, individual differences of the light source, and minor deviations of optical elements to produce offsets in opposite directions at the symmetrical positions. When the light paths are superimposed, they can be partially canceled out, thereby reducing optical distortion, suppressing local dark areas, and improving the overall uniformity of illumination.
[0041] See Figure 3 As shown, in another embodiment of this application, within any lighting zone 15, a plurality of first light sources 2 and a plurality of second light sources 3 are alternately distributed, and the arrangement of the plurality of first light sources 2 and the plurality of second light sources 3 in two lighting zones 15 that are symmetrically arranged about the second central axis of symmetry 14 is the same. This design enables the luminous flux of each lighting zone 15 to be spatially discretely and uniformly distributed, effectively avoiding abrupt changes in illuminance gradient caused by the aggregation of similar light sources. Moreover, when a single light source fails, the alternating distribution structure of the first light sources 2 and the second light sources 3 ensures that the failure point is surrounded by dissimilar light sources, so that the local failure only causes a linearly decaying change in illuminance.
[0042] Preferably, the light pattern of the first light source 2 is either a focused light pattern or a floodlight pattern, and the light pattern of the second light source 3 is either a focused light pattern or a floodlight pattern.
[0043] In this embodiment, within the first illumination region 12 and / or the second illumination region 13, the center distance between any two adjacent first light sources 2 and second light sources 3 is equal. This design further improves the uniformity of the final projected light spot.
[0044] Preferably, within the first lighting area 12 or the second lighting area 13, a plurality of first light sources 2 and a plurality of second light sources 3 are arranged in a straight line.
[0045] In summary, the light source arrangement structure proposed in this utility model includes a substrate body 1, which is divided into a first illumination region 12 and a second illumination region 13 along the first central symmetry axis 11 of the substrate body 1. The first illumination region 12 is provided with n first light sources 2 and m second light sources 3, and the second illumination region 13 is provided with m first light sources 2 and n second light sources 3. The arrangement of the n first light sources 2 and m second light sources 3 in the first illumination region 12 is opposite to the arrangement of the m first light sources 2 and n second light sources 3 in the second illumination region 13. The color temperature of the first light sources 2 is one of cool white and warm white, and the color temperature of the second light sources 3 is the other of cool white and warm white. n and m are both natural numbers greater than or equal to 1. This design divides the substrate body 1 into a first illumination region 12 and a second illumination region 13 based on the first central axis of symmetry 11. The first illumination region 12 is equipped with n first light sources 2 and m second light sources 3, while the second illumination region 13 is equipped with m first light sources 2 and n second light sources 3. The arrangement of the light sources in the first illumination region 12 is opposite to that in the second illumination region 13. This ensures that the n first light sources 2 in the first illumination region 12 are offset from the m first light sources 2 in the second illumination region 13, and the m second light sources 3 in the first illumination region 12 are offset from the n second light sources 3 in the second illumination region 13. This design creates a uniform color temperature interlacing network on the surface of the substrate body 1, where light of different color temperatures forms dense intersections on the projection path, significantly improving the microscale light mixing effect and increasing the uniformity of the final projected light spot. This solves the problem of poor light spot uniformity formed by close-range projection of light emitted from the light source device.
[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
