Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lighting structure and lighting system based on a specific light spot. Background Technology

[0002] For specific light spot requirements, such as the light distribution on round tabletops in restaurants, circular downlights are now commonly used. However, if the illumination angle of the downlight is too small, there will be dark areas at the edges of the tabletop. Figure 1a If the angle of the downlight is appropriate, the center of the desktop will be exposed, such as... Figure 1b If the downlight's beam angle is too wide, the illuminance will be low, and the light will spill beyond the tabletop. Figure 1c To achieve a greater amount of light illuminating the desktop area, with better light spot uniformity and less spillage, where 1 represents the desktop and 2 represents the light spot outline formed by the circular downlight, as in the invention patent application with application number CN202010183786.0, it enables the splicing of a coaxially arranged central light spot, an inner ring light spot, and an outer ring light plate. However, to ensure the uniformity of the light spot, the requirements for the outer ring light spot are higher. For example, the formation of the outer ring light spot requires the addition of a double freeform surface lens, and the relative positioning accuracy of the outer light source and the double freeform surface lens is required to increase the processing difficulty.

Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0021] 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 invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] This application provides an illumination structure based on a specific light spot for splicing together to form a composite light spot. The aforementioned illumination structure based on a specific light spot includes at least two light source modules and at least two lenses. The at least two lenses are configured to correspond one-to-one with the at least two light source modules. Light emitted from each light source module enters the corresponding lens, and the light exits through the corresponding lens to form a segmented light spot. The composite light spot is configured to be divided by at least one line to form at least two segmented light spot regions, and the at least two segmented light spot regions correspond one-to-one with the at least two segmented light spots.

[0023] The aforementioned illumination structure based on a specific light spot allows light emitted from each light source module to enter its corresponding lens, and the light exits through the lens to form a segmented light spot. This means that each light source module independently forms a segmented light spot. The combined light spot is configured to be divided by at least one line to form at least two segmented light spot regions. The at least two segmented light spot regions correspond one-to-one with the at least two segmented light spots, thus dividing the combined light spot into at least two segmented light spot regions. Each segmented light spot region is one of the "pieces" in assembling the complete combined light spot. This allows each light source module and its corresponding lens to directly form a segmented light spot that coincides with its corresponding segmented light spot region. The combined light spot can be formed simply by adjusting at least two light source modules and their corresponding lenses together to directly splice the at least two segmented light spots, without the need for additional optical components. This reduces the manufacturing difficulty and, for a specific light spot, achieves good light spot uniformity and less light overflow.

[0024] It should be noted that there are many ways to achieve the formation of a slit light spot that coincides with the slit light spot area by the light source module and lens. It can be well achieved by existing methods that use complex optical design and light shielding. However, this application does not protect the structure of the light source module and lens to form the slit light spot, but only protects the formation of the slit light spot that coincides with the slit light spot area by the light source module and lens. Then, the formation of a specific light spot is achieved by direct splicing, which achieves better light spot uniformity and less light overflow.

[0025] It should also be noted that one method for forming the segmented light spot is as follows: the light source module uses multiple 1W patch light sources arranged into the desired light spot shape. The specific arrangement can be achieved using existing optical designs. After arranging the multiple patch light sources into the desired light spot shape, a lens is used to form the desired light spot shape. Further, the number of patch light sources is 12 or 24. Further, the lens includes a condenser lens. Further, the condenser lens also includes a diffuser lens.

[0026] To better understand the illumination structure based on a specific light spot in this application, the following further explanation is provided: Please refer to the following: Figures 2 to 3One embodiment of the illumination structure 10 based on a specific light spot includes at least two light source modules 100 and at least two lenses 200. The at least two lenses 200 are configured in a one-to-one correspondence with the at least two light source modules 100. Light emitted from each light source module 100 enters the corresponding lens 200, and the light exits through the corresponding lens 200 to form a segmented light spot 10a. The combined light spot 20a is configured to be divided by at least one line to form at least two segmented light spot regions, and the at least two segmented light spot regions correspond to and overlap with the at least two segmented light spots 10a.

[0027] The aforementioned illumination structure 10 based on a specific light spot allows light emitted from each light source module 100 to enter the corresponding lens 200. The light exits through the corresponding lens 200 to form a segmented light spot 10a, thus enabling each light source module 100 to independently form a segmented light spot. The combined light spot 20a is configured to be divided by at least one line to form at least two segmented light spot regions. The at least two segmented light spot regions correspond one-to-one with the at least two segmented light spots 10a, thus enabling the combined light spot 20a to divide into at least two segmented light spot regions, and each segmented light spot region is pieced together. One of the "pieces" in the complete spliced ​​light spot 20a is used to directly form a segmented light spot 10a that overlaps with the corresponding segmented light spot area by cooperating with each light source module 100 and the corresponding lens 200. This allows at least two light source modules 100 and the corresponding lenses 200 to be adjusted together to directly splice at least two segmented light spots 10a to complete the formation of the spliced ​​light spot 20a. No additional optical components are needed to process the segmented light spot, reducing the processing difficulty. Furthermore, for specific light spots, it achieves better light spot uniformity and less spillage light.

[0028] Please refer to the following: Figures 4 to 5 ,or Figures 8 to 9 In one embodiment, light is emitted through a corresponding lens 200 to form a segmented light spot 10a with a beam angle of 24° to 36°, which can better ensure the uniformity of the segmented light spot 10a and the edge sharpness of the segmented light spot 10a. Figure 4 A simulated fan-shaped beam pattern with a beam angle of 24°; Figure 5 A simulated fan-shaped beam pattern with a beam angle of 36°; Figure 8 A simulated rectangular beam pattern with a beam angle of 24°; Figure 9 This is a simulated rectangular beam pattern with a beam angle of 36°.

[0029] In one embodiment, the spliced ​​spot is configured to form at least two segmented spot regions by being divided by at least a straight line and / or at least an arc.

[0030] In one embodiment, the combined light spot is a circular combined light spot. Further, the combined light spot is configured to be divided into two segmented light spot areas by a straight line, with the center of the combined light spot located on the straight line, so that each segmented light spot area is a semi-circular segmented light spot area, which effectively alleviates the problems of overexposure in the center of the desktop, obvious dark areas at the edges, and excessive spillage light.

[0031] Please refer to the following: Figures 12 to 13 In one embodiment, the stitched light spot 20a is a rectangular stitched light spot 20a. Further, the stitched light spot 20a is configured to be divided into two segmented light spot areas by a straight line, the straight line being parallel to any side of the rectangle, so that each segmented light spot area is a rectangular segmented light spot area, effectively mitigating the problems of overexposure in the center of the desktop, obvious dark areas at the edges, and excessive spillage. Further, the stitched light spot is configured to be divided into three parallel segmented light spot areas by two straight lines, each straight line being parallel to the same side of the rectangle, so that each segmented light spot area is a rectangular segmented light spot area.

[0032] Please refer to the following: Figures 2 to 3 In one embodiment, the illumination structure 10 based on a specific light spot includes multiple light source modules 100 and multiple lenses 200. The multiple lenses 200 are arranged in a one-to-one correspondence with the multiple light source modules 100. The combined light spot 20a is configured to be divided into multiple segmented light spot regions by at least two intersecting lines, and the multiple segmented light spot regions correspond to and overlap with the multiple segmented light spots 10a. It can be understood that light emitted from each light source module 100 enters the corresponding lens 200, and the light exits through the corresponding lens 200 to form the segmented light spot 10a, thus enabling each light source module 100 to independently form a segmented light spot. With the combined light spot 20a configured to be divided into multiple segmented light spot regions by at least two intersecting lines, and the multiple segmented light spot regions corresponding to and overlapping with the multiple segmented light spots 10a, the combined light spot 20a is divided into at least four segmented light spot regions, and each segmented light spot region is a combined light spot. One of the "pieces" in 20a is used to directly form a segmented light spot 10a that overlaps with the corresponding segmented light spot area by cooperating with each light source module 100 and the corresponding lens 200. This allows at least four light source modules 100 and the corresponding lenses 200 to be adjusted together to form at least four segmented light spots 10a for direct splicing, thus completing the formation of the spliced ​​light spot 20a. No additional optical components are needed to process the segmented light spot, reducing the processing difficulty. Furthermore, for specific light spots, it achieves better light spot uniformity and less spillage.

Further, the stitched light spot 20a is configured to be divided into four segmented light spot regions by two perpendicularly arranged straight lines. Further, the stitched light spot is configured to be divided into six segmented light spot regions by three equally spaced circularly arranged straight lines, which effectively alleviates the problems of overexposure in the center of the desktop, obvious dark areas at the edges, and excessive spillage light.
