Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of lighting devices, and in particular to a high-efficiency and easy-to-use lighting device with a switchable grid. Background Technology
[0002] A grid light source is a lighting device that uses a built-in grid structure (such as a mesh or multiple spaced strips) to directionally control light. The grid structure limits the scattering range of the light, improves its directionality, and thus focuses the light more precisely on the target area. Simultaneously, the grid structure blocks direct light, reducing glare and visual interference. Therefore, grid light sources are suitable for scenarios requiring precise light control, glare avoidance, or enhanced spatial hierarchy. Specifically, in the field of machine vision inspection, grid light sources are mainly used in scenarios requiring precise light control, high-contrast imaging, or 3D measurement. In practice, when using grid light sources to illuminate workpieces, users typically encounter the following two usage scenarios:
[0003] Use Case 1: When faced with complex detection requirements, users need to adjust the phase of the grid structure. Currently, most users achieve this by changing the position of the grid structure inside the grid light source or by directly replacing it with another grid light source that has the required phase.
[0004] Use Case 2: Different workpieces require different grid structures. Currently, most users achieve this by changing the grid structure inside the grid light source or by directly replacing it with a grid light source that has the required grid structure.
[0005] As can be seen from the above, the operation of existing grid light sources is cumbersome when users need to change the phase of the grid structure or in scenarios where the grid structure needs to be changed. They cannot quickly adjust the phase of the grid structure or use different grid structures. Therefore, it is necessary to improve the existing grid light sources. Utility Model Content
[0006] This invention provides a highly efficient and easy-to-use lighting device for switching grids, mainly addressing the technical problem of how to design the lighting device so that it can quickly adjust the phase of the grid structure and quickly use different grid structures.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A highly efficient and easy-to-use lighting device with a switchable grid includes a fixed base, a driving wheel, a driven wheel, a transmission belt, and a light source. The driving wheel and the driven wheel are rotatably connected to the fixed base, respectively. The light source is disposed between the driving wheel and the driven wheel. The transmission belt is wound around the driving wheel and the driven wheel, and surrounds the light source. The transmission belt is transparent, and its surface is provided with at least one grid pattern for light blocking. The light-emitting surface of the light source faces the transmission belt, so that when the transmission belt moves under the drive of the driving wheel, the grid pattern can move onto the light-emitting path of the light source.
[0009] In one of the technical solutions, two types of grid patterns are provided on the surface of the transmission belt, and when one of the grid patterns is located on the light emission path of the light source, the other grid pattern is located on the back side of the light emission surface of the light source.
[0010] In one of the technical solutions, the light source is configured to emit light downwards, and when one of the grid patterns is located below the light source, the other grid pattern is located above the light source.
[0011] In one of the technical solutions, the transmission belt is a film sheet engraved with the grid pattern, and the first and last ends of the film sheet are connected to each other to form a loop-shaped transmission belt.
[0012] In one of the technical solutions, the grid pattern includes multiple light-shielding stripes spaced apart.
[0013] In one technical solution, the distance between the driven wheel and the driving wheel is adjustable so that the driving wheel and the driven wheel can jointly tension the transmission belt.
[0014] In one of the technical solutions, the outer diameter of both the driving wheel and the driven wheel is greater than the thickness of the light source.
[0015] In one of the technical solutions, the lighting device further includes a motor, which is connected to the drive wheel and used to drive the drive wheel to rotate.
[0016] In one of the technical solutions, the lighting device further includes a handle and a scale. The handle is fixedly connected to the drive wheel, and the scale is located on one side of the grid pattern and extends in the direction of movement of the transmission belt.
[0017] In one of the technical solutions, the color and brightness of the light source are both adjustable.
[0018] Compared with the prior art, the efficient and simple grid switching lighting device provided by this utility model has at least the following beneficial effects:
[0019] The grid pattern on the transmission belt in this solution is equivalent to the grid structure on an existing grid light source. During use, the transmission belt can be moved by driving the drive wheel, thereby moving the grid pattern and rapidly changing its phase. Therefore, this solution is particularly suitable for lighting needs requiring a gradual increase in the phase of the grid pattern. Furthermore, when multiple grid patterns are provided on the transmission belt, simply driving the drive wheel to move the desired grid pattern onto the light source's path allows for the rapid use of various grid patterns. In summary, this lighting device offers the advantages of simple operation and efficient switching. Users can quickly adjust the phase of the grid structure and rapidly use different grid structures to quickly meet the actual needs of grid lighting. Attached Figure Description

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0030] 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.
[0031] Please refer to the following: Figure 1 and Figure 2 This utility model provides an efficient and simple grid-switching lighting device, specifically including a fixed base 1, a driving wheel 2, a driven wheel 3, a transmission belt 4, and a light source 5. The driving wheel 2 and the driven wheel 3 are rotatably connected to the fixed base 1 via connecting bearings. The light source 5 is positioned between the driving wheel 2 and the driven wheel 3. The transmission belt 4 is wound around both the driving wheel 2 and the driven wheel 3, and also surrounds the light source 5. The emitting surface of the light source 5 faces the transmission belt 4, and the transmission belt 4 is transparent, allowing the light emitted by the light source 5 to pass through and illuminate the surface of the workpiece being inspected. The surface of the transmission belt 4 is provided with at least one grid pattern 41 for light shielding. When the grid pattern 41 moves onto the light-emitting path of the light source 5, the lighting device of this solution achieves the function of illuminating the object in a grid pattern.
[0032] Specifically, the grid pattern 41 on the transmission belt 4 in this solution is equivalent to the grid structure on an existing grid light source. In use, the transmission belt 4 can be moved by driving the drive wheel 2 to rotate, thereby moving the grid pattern 41 and quickly changing the phase of the grid pattern 41. Therefore, this solution is particularly suitable for lighting needs in the market that require the phase of the grid pattern 41 to gradually increase. In addition, when multiple grid patterns 41 are set on the transmission belt 4, it is only necessary to drive the drive wheel 2 to move the desired grid pattern 41 to the light emission path of the light source 5, so that various different grid patterns 41 can be used quickly. In summary, the lighting device of this solution has the advantages of simple operation and efficient switching, which allows users to quickly adjust the phase of the grid structure and quickly use different grid structures to quickly meet the actual needs of grid lighting.
[0033] It should be noted that grid pattern 41 can be as follows: Figure 1 The diagram shows multiple spaced light-blocking stripes. The grid pattern 41 can also be a mesh, honeycomb, or other shapes. Different types of grid patterns 41 can be understood as having similar shapes but different dimensions (for example, multiple grid patterns 41 all include multiple light-blocking stripes, but the spacing or width of the light-blocking stripes is different), or they can be understood as having different shapes (for example, multiple grid patterns 41 are light-blocking stripe-shaped, mesh-shaped, or honeycomb-shaped, etc.).
[0034] Please refer to the following: Figure 1 and Figure 2 In this embodiment, the surface of the transmission belt 4 preferably has two types of grid patterns 41. When one grid pattern 41 is located on the light emission path of the light source 5, the other grid pattern 41 is located on the back side of the light emission surface of the light source 5. More preferably, the light source 5 is designed to emit light downwards, so when one grid pattern 41 is located below the light source 5, the other grid pattern 41 is actually located on top of the light source 5. By driving the drive wheel 2 to rotate, the two grid patterns 41 can be quickly switched, thereby efficiently meeting the actual needs of users using grid lighting. In addition, the emission color and brightness of the light source 5 can be designed to be adjustable to meet more visual inspection needs of users.
[0035] In this embodiment, the transmission belt 4 is specifically designed as a film sheet engraved with at least one grid pattern 41. In use, the first and second ends of the film sheet need to be connected together to form a loop transmission belt 4. The film sheet not only has good light transmission characteristics, enabling higher illumination brightness from the lighting device, but also allows for the low-cost customization of various light-shielding patterns on its surface. Using film sheet as the transmission belt 4 has the advantages of simple procurement and low cost.
[0036] Please refer to them again. Figure 1 and Figure 2 The distance between the driven wheel 3 and the driving wheel 2 is designed to be adjustable to tension the film serving as the transmission belt 4. Specifically, the tension of the film can be achieved by changing the position of the driven wheel 3 or the position of the driving wheel 2. In addition, the outer diameters of both the driving wheel 2 and the driven wheel 3 are designed to be larger than the thickness D of the light source 5, ensuring that when the film serving as the transmission belt 4 is driven by the driving wheel 2, the film will not be scratched by the sharp edges of the surface of the light source 5.
[0037] Please refer to them again. Figure 1 and Figure 2 The lighting device in this embodiment also includes a motor 6, which is connected to a drive wheel 2. When the motor 6 rotates, it drives the drive wheel 2 to rotate, thereby driving the film sheet, which serves as the transmission belt 4, to move, thus adjusting the phase of the grid pattern 41 or switching to other grid patterns 41. By using electric control, the accuracy of adjusting the phase of the grid pattern 41 or moving other grid patterns 41 to a specified position will be more precise, and the adjustment speed will also be faster.
[0038] Of course, for other embodiments, please refer to Figure 3 The lighting device may also include a handle 7 and a scale 8, wherein the handle 7 is designed to be fixed on the drive wheel 2, and the scale 8 is designed to be located on one side of the grid pattern 41 and extend in the direction of movement of the drive belt 4. With this design, the user can drive the film, which serves as the drive belt 4, to move by manually rotating the drive wheel 2, and precisely adjust the phase of the grid pattern 41 or move other desired grid patterns 41 to a specified position by reading the scale 8.
[0039] 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.
