Description

Technical Field

[0001] This utility model relates to the technical field of light sources, and in particular to a strip light source with adjustable multi-color spot size. Background Technology

[0002] Bar light sources are a common type of light source. In a bar light source, light emitted from a strip-shaped light panel is directed towards a focusing rod. The focusing rod, through internal total internal reflection and scattering, evenly distributes and concentrates the light in a specific direction, reducing scattering and waste, thus forming a uniform, concentrated bar-shaped light spot. In applications such as machine vision and barcode scanning, uniform light distribution can improve image quality or scanning accuracy. However, current bar light sources have a fixed light spot size or color, lacking the ability to adjust both the spot size and color. This fails to meet the needs of applications requiring frequent adjustments to both spot size and color. Therefore, improvements to existing bar light sources are necessary. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Please refer to the following: Figures 1 to 3This utility model embodiment provides a multi-color adjustable light spot size strip light source, mainly including a base 1, a lamp board 2, a focusing rod 3, an adjustment component 4, and a light color adjustment mechanism 5. The lamp board 2 is used to emit light. The lamp board 2 can be understood as a circuit board with multiple LED beads that can emit light when powered. The focusing rod 3 is preferably cylindrical in shape and is set on the light emission path of the lamp board 2 so that the focusing rod 3 can receive the light emitted by the lamp board 2. The light color adjustment mechanism 5 is connected between the base 1 and the lamp board 2. The light color adjustment mechanism 5 is used to adjust the color of the light emitted by the lamp board 2 to the focusing rod 3. The focusing rod 3 is fixed on the adjustment component 4. The adjustment component 4 is movably connected to the base 1 and is used to adjust the distance between the focusing rod 3 and the lamp board 2.

[0027] Specifically, during operation, the lamp board 2 emits light after being powered on. The light is focused by the spotlight rod 3 to form a uniform and concentrated strip of light. When the position of the adjustment component 4 is adjusted, the distance between the spotlight rod 3 and the lamp board 2 can be adjusted, thereby changing the size of the light spot. In addition, the color of the light spot can be adjusted by triggering the color adjustment mechanism 5. In summary, the light source using this solution can meet the usage requirements where both the size and color of the light spot need to be adjustable.

[0028] Please refer to them again. Figures 1 to 3 The light color adjustment mechanism 5 specifically includes an adjustment seat 51, which is movably connected to the base 1. Multiple light panels 2 with different light colors are fixed on the adjustment seat 51. When the adjustment seat 51 moves relative to the base 1, any one of the light panels 2 can face the focusing rod 3, thereby adjusting the color of the light spot. It is understood that the movement of the adjustment seat 51 relative to the base 1 includes, but is not limited to, linear movement, curved movement, or rotational movement. Preferably, in this scheme, the adjustment seat 51 is rotatably connected to the base 1 with the central axis L as its rotation axis. That is, by driving the adjustment seat 51 to rotate around the central axis L, the position of the light panel 2 with different light colors facing the focusing rod 3 is changed, thereby adjusting the color of the light spot. Based on this, preferably, the central axis L is parallel to the axial direction of the focusing rod 3, and the multiple light panels 2 are arranged sequentially at intervals around a circumference of the central axis L, so that when the adjustment seat 51 is rotated and the desired light panel 2 is facing the focusing rod 3, the distance from the light panel 2 facing the focusing rod 3 remains constant, thereby ensuring that the size of the light spot does not change after adjusting the color. Preferably, four light panels 2 of different colors are fixed on the adjustment seat 51 of this scheme.

[0029] In one embodiment, when the adjustment seat 51 is rotated into place, the lamp panel 2 facing the spotlight bar 3 can be designed to light up automatically, while the other lamp panels 2 not facing the spotlight bar 3 can be designed to turn off automatically.

[0030] Please refer to them again. Figures 1 to 3The adjusting base 51 specifically includes multiple lamp holders 511 and two rotating disks 512. The multiple lamp holders 511 are arranged sequentially at intervals around a central axis L. Each lamp holder 511 has a lamp plate 2 fixed on it. The two rotating disks 512 are located at opposite ends of the multiple lamp holders 511 and are fixedly connected to the multiple lamp holders 511. Both rotating disks 512 are rotatably connected to the base 1 about the central axis L. This adjusting base 51 facilitates the fixing of multiple lamp plates 2 and facilitates rotatable connection with the base 1, and has the advantage of simple structure.

[0031] In other embodiments, in addition to the structure described above, the light color adjustment mechanism 5 can also be a traditional light color controller. Correspondingly, the lamp board 2 needs to be equipped with a variety of lamp beads of different colors. The light color controller is electrically connected to all the lamp beads on the lamp board 2. The light color controller can also change the color of the light spot by controlling the lamp beads of different colors on the lamp board 2 to light up.

[0032] Please see Figure 1 The base 1 specifically includes a base plate 11 and two side plates 12. The two side plates 12 are respectively disposed on opposite sides of the base plate 11 and are fixedly connected to the base plate 11. One of the rotating disks 512 and one of the side plates 12 are rotatably connected about the central axis L. The other rotating disk 512 and the other side plate 12 are rotatably connected about the central axis L.

[0033] Please refer to it again. Figure 1 The adjusting component 4 specifically includes two sliding brackets 41. The aforementioned focusing rod 3 is fixed between the two sliding brackets 41. One sliding bracket 41 and one side plate 12 are slidably connected in the longitudinal direction, and the other sliding bracket 41 and the other side plate 12 are slidably connected in the longitudinal direction. When the sliding bracket 41 is operated to slide relative to the side plate 12, the distance between the focusing rod 3 and the lamp plate 2 can be adjusted, thereby achieving the purpose of changing the size of the light spot.

[0034] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
