Description

Technical Field

[0001] This utility model belongs to the field of LED module testing technology, and specifically relates to a universal fixing device for LED modules using a photometric distribution testing fixture. Background Technology

[0002] As the fourth generation of lighting sources, LED lighting products are becoming increasingly popular, leading to higher demands for their performance. Modern LED lighting designs are also increasingly leaning towards modularity. Currently, there are no mandatory national standards for the size and interface of LED modules. Most LED modules on the market are designed by individual manufacturers to suit their own needs, making interoperability between different manufacturers difficult.

[0003] Currently, there is no dedicated bracket for installing and testing LED modules using a vertical genomic photometer. As the volume of LED module testing increases significantly, installing and testing LED modules has become a major headache for testing engineers. Without a dedicated LED module testing bracket, how can the installation of LED modules be completed accurately and efficiently?

[0004] A search revealed that Chinese Patent Publication No. CN219977738U, authorized on November 7, 2023, discloses a universal fixing device for downlights using a photometric distribution testing fixture. The device includes a fixed bracket and a rotating chuck. The rotating chuck is fixed to the fixed bracket and includes a turntable, a base, and several jaws disposed between the turntable and the base. The jaws are joined together to form a plane, and a locking assembly restricts the relative sliding between the turntable and the base. Rotating the turntable causes the jaws to slide outwards on the base, creating adjustable through holes between the jaws. This application allows for the installation and fixing of downlights of various sizes using only a rotating chuck, avoiding the need to repeatedly replace the annular gaskets, shortening the downlight installation time for testing personnel, improving testing efficiency, and increasing the utilization rate of the photometric meter within the same timeframe.

[0005] However, the device still has the following drawbacks: Although the above embodiments increase output and reduce product time costs, the device has limitations in fixing LED light modules and cannot limit their position, thus limiting its use. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a universal fixing device for LED modules in a photometric distribution testing fixture, comprising a fixing cylinder, a U-shaped bracket, and a base. The base contains a lead screw and two sets of sliders, and its surface has two sets of fixing seats. When the lead screw rotates clockwise, the two sets of sliders move the two sets of fixing seats closer together; when the lead screw rotates counterclockwise, the two sets of sliders move the two sets of fixing seats further apart.

[0007] Furthermore, a set of first adjusting screws is provided on both sides of the base, and a second adjusting screw is provided on the surface of the U-shaped bracket. The two sets of first adjusting screws are symmetrically arranged with the central axis of the base as the center, and the two sets of first adjusting screws are connected through to both sides of the base.

[0008] Furthermore, the U-shaped bracket and the base are detachably connected by two sets of first adjusting screws, and the fixed cylinder and the U-shaped bracket are detachably connected by a second adjusting screw.

[0009] Furthermore, a limiting groove is formed through the surface of the base, the lead screw is located inside the limiting groove, both sets of sliders are slidably connected to the inside of the limiting groove, both sets of sliders are slidably sleeved on the surface of the lead screw, and both sets of sliders are symmetrically arranged with the central axis of the lead screw as the center.

[0010] Furthermore, the two sets of fixed seats are respectively connected to the two sets of sliders, and the two sets of fixed seats are symmetrically arranged with the central axis of the base as the center.

[0011] Furthermore, the surface of the U-shaped bracket is provided with a first connecting block, which is located at the center of the surface of the U-shaped bracket, and one end of the fixing cylinder is provided with a second connecting block, which is fitted and connected to the first connecting block.

[0012] Furthermore, the surface of the fixing cylinder is provided with several sets of fixing screws, and the several sets of fixing screws are arranged in a circular array with the central axis of the fixing cylinder as the center. The surface of the base is provided with an LED module body.

[0013] Furthermore, several sets of limiting connection holes are provided at both ends of the LED module body, and two sets of positioning screws are provided through the surface of the two sets of fixing seats. The LED module body is detachably connected to the two sets of fixing seats through the two sets of positioning screws, and the two sets of fixing seats are provided with sliding grooves.

[0014] The beneficial effects of this utility model are:

[0015] 1. The module can be adjusted to the appropriate installation length simply by rotating the lead screw, and then fixed in place by the positioning screws, enabling rapid installation of modules of different sizes. Adjusting the first and second adjusting screws controls the adjustment of the module's light-emitting surface, shortening the installation time of LED modules while improving the equipment's practicality.

[0016] 2. The fixed cylinder and the U-shaped bracket are detachably connected by the second adjusting screw. The LED module body is then detachably connected to two sets of fixed seats by two sets of positioning screws. Since the fixed cylinder is connected to the test equipment by the fixing screws, and the position of the entire test fixture can be adjusted by the fixing screws, it is convenient to disassemble or install the equipment, which improves maintenance efficiency and achieves the effect of easy disassembly and assembly.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] This utility model embodiment provides a universal fixing device for LED modules in a photometric distribution testing fixture, including a fixing cylinder 3, a U-shaped bracket 2, and a base 1; for example, such as Figure 1-3 As shown.

[0025] Both sides of the base 1 are provided with a set of first adjusting screws 11. The two sets of first adjusting screws 11 are symmetrically arranged with the central axis of the base 1 as the center, and both sets of first adjusting screws 11 are connected through to both sides of the base 1. The U-shaped bracket 2 is detachably connected to the base 1 through the two sets of first adjusting screws 11. A limiting groove 16 is formed through the surface of the base 1. A lead screw 12 is provided inside the base 1. The lead screw 12 is located inside the limiting groove 16.

[0026] The base 1 has two sets of sliders 13 inside, and both sets of sliders 13 are slidably connected to the inside of the limiting groove 16. Both sets of sliders 13 are slidably sleeved on the surface of the lead screw 12, and both sets of sliders 13 are symmetrically arranged with the central axis of the lead screw 12 as the center. The surface of the base 1 has two sets of fixing seats 14, and the two sets of fixing seats 14 are respectively connected to the two sets of sliders 13, and both sets of fixing seats 14 are symmetrically arranged with the central axis of the base 1 as the center.

[0027] Specifically, the lead screw 12 is located inside the limiting groove 16, and the lead screw 12 can rotate clockwise and counterclockwise. The rotation of the lead screw 12 can drive the slider 13 to move in a relatively linear manner. When the lead screw 12 rotates clockwise, the two sets of sliders 13 drive the two sets of fixed seats 14 to move closer to each other. When the lead screw 12 rotates counterclockwise, the two sets of sliders 13 drive the two sets of fixed seats 14 to move further apart.

[0028] The surface of the U-shaped bracket 2 is provided with a first connecting block 22, which is located at the center of the surface of the U-shaped bracket 2. The surface of the U-shaped bracket 2 is provided with a second adjusting screw 21. One end of the fixing cylinder 3 is provided with a second connecting block 32. The second connecting block 32 is fitted and connected to the first connecting block 22. The second adjusting screw 21 is threadedly connected to the first connecting block 22 and the second connecting block 32. The fixing cylinder 3 and the U-shaped bracket 2 are detachably connected by the second adjusting screw 21.

[0029] Specifically, the upper and lower fixing holes of the U-shaped bracket are relatively perpendicular. The upper hole allows the U-shaped bracket 2 to swing back and forth relative to the fixing cylinder 3 around the hole, while the lower hole allows the base 1 to swing left and right relative to the U-shaped bracket 2.

[0030] The surface of the fixed cylinder 3 is provided with a number of sets of fixing screws 31, and the sets of fixing screws 31 are arranged in a circular array with the central axis of the fixed cylinder 3 as the center.

[0031] Specifically, the fixed cylinder 3 is connected to the testing equipment via a fixing screw 31.

[0032] The surface of the base 1 is provided with an LED module body 4. Both ends of the LED module body 4 are provided with several sets of limiting connection holes 41. The several sets of limiting connection holes 41 are symmetrically arranged with the central axis of the LED module body 4 as the center. The surfaces of the two sets of fixing seats 14 are provided with two sets of positioning screws 15. The LED module body 4 is detachably connected to the two sets of fixing seats 14 through the two sets of positioning screws 15. The two sets of fixing seats 14 are provided with sliding grooves.

[0033] Specifically, since the two sets of fixing seats 14 are provided with sliding grooves, the LED module body 4 is installed between the two sets of fixing seats 14 by adjusting the position of the two sets of fixing seats 14. The LED module body 4 can slide freely in the sliding grooves. Then, the LED module body is fixed by two sets of positioning screws 15 passing through two sets of limiting connection holes 41 on the surface of the LED module body 4.

[0034] The working principle of the universal fixing device for LED modules using the photometric distribution testing fixture proposed in this embodiment is as follows:

[0035] By loosening the second adjusting screw 21, the U-shaped bracket can swing back and forth relative to the fixed cylinder 3; by tightening the second adjusting screw 21, the U-shaped bracket 2 is fixed relative to the fixed cylinder 3.

[0036] The U-shaped bracket 2 and the base 1 are connected by the first adjusting screw 11. By loosening the first adjusting screw 11, the base 1 swings left and right relative to the U-shaped bracket 2. By tightening the second adjusting screw, the base 1 is fixed relative to the U-shaped bracket 2.

[0037] The base 1 is equipped with a lead screw 12, and two sliders 13 are mounted on both ends of the lead screw 12. When the lead screw is rotated clockwise, the sliders 13 move closer to each other, and when the lead screw 12 is rotated counterclockwise, the sliders 13 move further apart. The bottoms of both sets of sliders 13 are connected to the fixed base 14.

[0038] The rotation of the lead screw 12 can control the fixed seat 14 to move closer to or further away from each other;

[0039] The bottom of the mounting base is provided with a sliding groove, and the bottom of the sliding groove is provided with a positioning screw 15. The left and right installation positions of the LED module body 4 can be adjusted by tightening or loosening the positioning screw 15.

[0040] During use, the fixed cylinder 3 is connected to the test equipment through the fixing screw 31, and the orientation of the entire test fixture can be adjusted by the fixing screw;

[0041] The light-emitting surface of the LED module body 4 is controlled to be horizontal by adjusting the first adjusting screw 11 and the second adjusting screw 21;

[0042] Move the LED module body by tightening or loosening the positioning screw 15, so that the LED module body is aligned with the center of the detector of the device.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
