Description

Technical Field

[0001] This utility model relates to the field of LED light source performance testing technology, and in particular to an LED light source performance testing device. Background Technology

[0002] LED light sources are light-emitting diodes. These light sources have advantages such as small size, long lifespan, and high efficiency, and can be used continuously for up to 100,000 hours. Therefore, they are widely used in the lighting field. As a common lighting device, LED light sources need to undergo various mechanical performance tests during production and use to ensure that their quality and performance meet standards and requirements. Mechanical performance tests include impact resistance tests, vibration resistance tests, pressure resistance tests, tensile resistance tests, abrasion resistance tests, tilt resistance tests, waterproof performance tests, and dustproof performance tests.

[0003] A search revealed that patent CN118706414A discloses an LED light source performance testing device and method; however, this testing device has the following shortcomings in use:

[0004] While it can test LED light sources during use, when multiple LED light sources need to be tested, they must be tested one by one, and multiple LED light sources cannot be tested simultaneously, resulting in low efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, which, while capable of testing LED light sources, require testing each LED light source individually when multiple LED light sources need to be tested, resulting in low efficiency. Therefore, this invention proposes an LED light source performance testing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An LED light source performance testing device includes a base plate, a frame fixedly mounted on the top of the base plate, the frame being U-shaped, suction cups fixedly mounted at the four bottom corners of the base plate to facilitate the base plate adhering to a table, and a vibration plate provided on the base plate.

[0008] A clamping mechanism is installed on the vibrating plate to clamp the LED light source;

[0009] The vibration mechanism is installed on the vibration plate to vibrate the LED light source.

[0010] In one possible design, the clamping mechanism includes a placement plate, two clamping plates, a bidirectional lead screw, and a knob for facilitating rotation of the bidirectional lead screw. The bottom of the placement plate is fixedly connected to the top of the vibrating plate. A first groove is formed on the top of the placement plate. One end of the bidirectional lead screw is rotatably connected to the inner wall of one side of the first groove. The other end of the bidirectional lead screw passes through one side of the placement plate and is fixedly connected to one side of the knob. The clamping plates are T-shaped, and the bottom ends of both clamping plates are slidably connected to the inner wall of the first groove. A lead screw nut is embedded in one side of the clamping plate, and the lead screw nut is threadedly connected to the bidirectional lead screw. The clamping mechanism consists of three sets.

[0011] In one possible design, the vibration mechanism includes two vibration motors and two housings. The bottom of the vibration plate has two second grooves. The tops of the two vibration motors are fixedly connected to the inner walls of the tops of the two second grooves, respectively. The two ends of the vibration plate are T-shaped and are slidably connected to the inner walls of the two housings, respectively. The two sides of the two housings are slidably connected to the inner walls of the two sides of the frame, respectively. Two second springs are fixedly installed on one side of the inner wall of each of the two housings. One end of each second spring is fixedly connected to one side of the vibration plate. Two first springs are fixedly installed at the bottom of each of the two housings. The bottom ends of each first spring are fixedly connected to the top of the base plate.

[0012] In one possible design, two fixing plates are fixedly installed on each side of the frame, and a black screen is provided on one side of the four fixing plates to facilitate observation of the LED light source.

[0013] In one possible design, hook and loop fasteners are glued to one side of each of the four fixing plates, and hook and loop fasteners are sewn to the four corners of the black curtain, with the hook and loop fasteners being bonded together.

[0014] In one possible design, the inner walls on both sides of the frame are provided with grooves to improve the stability of the box movement, and a slider is fixedly installed on one side of each of the two boxes, with one side of the slider slidably connected to the inner wall of the groove.

[0015] In one possible design, rubber pads are fixedly provided on the sides of the two clamps that are close to each other to improve the fixing effect.

[0016] In this application, during use, the entire device is placed on a table, and the base plate is firmly attached to the table using suction cups to prevent the device from moving during testing. The LED light source to be tested is placed on the placement plate (located between two clamping plates, with the light-emitting part of the LED light source facing the black screen). Rotating the knob drives the bidirectional lead screw to rotate. Since a lead screw nut is embedded in one side of the clamping plate, and the lead screw nut is threadedly connected to the bidirectional lead screw, the rotation of the bidirectional lead screw will drive the two clamping plates to move towards the center, thereby clamping the LED light source. After fixing the three LED light sources on the placement plate, the external vibration motor and the power supply and controller for the LED light sources are connected. Power can be supplied through the power cords of the vibration motor and the LED light sources and an external power socket. Then, the vibration motor and the LED light sources are started. When the vibration motor is started, it drives the vibrating plate to vibrate, which in turn causes the LED light source clamped on the vibrating plate to vibrate for testing. The first and second springs allow the shield to vibrate up, down, left, and right. During vibration, observe whether the LED light source fails to light up. If it does, the LED light source performance does not meet the standard. Because three sets of clamping mechanisms are set, three LED light sources can be clamped, allowing for simultaneous testing of three LED light sources, effectively improving testing efficiency. The number of clamping mechanisms can be added or reduced according to actual needs. The black curtain can block external light, making it easy to observe the lighting status of the LED light source under vibration. Since the black curtain is fixed by Velcro hook and Velcro loop side, it can be easily disassembled for cleaning.

[0017] The beneficial effects of this utility model are as follows:

[0018] In this utility model, the LED light source performance testing equipment uses a clamping mechanism to place the LED light source to be tested on a placement plate (located between two clamping plates, with the light-emitting part of the LED light source facing a black screen). Rotating the knob drives the bidirectional lead screw to rotate. Since a lead screw nut is embedded in one side of the clamping plate and is threadedly connected to the bidirectional lead screw, the rotation of the bidirectional lead screw will drive the two clamping plates to move towards the middle, thereby clamping the LED light source. Because three sets of clamping mechanisms are set, three LED light sources can be clamped and tested simultaneously, effectively improving the testing efficiency.

[0019] In this utility model, the LED light source performance testing equipment, through the vibration mechanism, when the vibration motor is started, will drive the vibration plate to vibrate, thereby driving the LED light source clamped on the vibration plate to perform vibration testing;

[0020] In this invention, the LED light source can be clamped by the clamping mechanism. Since three sets of clamping mechanisms are set, three LED light sources can be clamped and tested at the same time, which effectively improves the testing efficiency. The vibration mechanism can be used to test the vibration of the LED light source on the vibration plate. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1

[0030] Reference Figure 1-6A performance testing device includes: a base plate 1, a frame 2, suction cups 3, a fixing plate 4, a black curtain 5, a vibration plate 7, a clamping mechanism, and a vibration mechanism. The base plate 1 serves as the supporting foundation for the entire device. The frame 2 is U-shaped and fixedly mounted on top of the base plate 1 to support and secure other components. The suction cups 3 are located at the four bottom corners of the base plate 1, facilitating its attachment to a tabletop and ensuring stability during use.

[0031] A clamping mechanism is mounted on the vibrating plate 7 to clamp the LED light source. The clamping mechanism includes a placement plate 8, two clamping plates 6, a bidirectional lead screw 14, and a knob. The bottom of the placement plate 8 is fixedly connected to the top of the vibrating plate 7, and a first groove 15 is formed on the top. One end of the bidirectional lead screw 14 is rotatably connected to the inner wall of one side of the first groove 15, and the other end passes through one side of the placement plate 8 and is fixedly connected to one side of the knob. The two clamping plates 6 are T-shaped, with their bottom ends slidably connected to the inner wall of the first groove 15, and each has a lead screw nut embedded in one side, threadedly connected to the bidirectional lead screw 14. By rotating the knob, the bidirectional lead screw 14 can be rotated, thereby driving the two clamping plates 6 to move towards or away from each other, thus clamping or releasing the LED light source.

[0032] To improve the clamping effect, rubber pads 16 are fixedly installed on the sides of the two clamping plates 6 that are close to each other, to increase the friction between them and the LED light source and prevent the LED light source from slipping during vibration. The clamping mechanism consists of three sets, which can clamp three LED light sources simultaneously for testing, thereby improving work efficiency.

[0033] A vibration mechanism is also installed on the vibration plate 7 for vibration testing of the LED light source. The vibration mechanism includes two vibration motors 17 and two housings 9. Two second grooves 18 are formed at the bottom of the vibration plate 7, and the tops of the two vibration motors 17 are fixedly connected to the inner walls of the tops of the two second grooves 18. The two ends of the vibration plate 7 are T-shaped and slidably connected to the inner walls of the two housings 9. The two sides of the two housings 9 are slidably connected to the inner walls of the two sides of the frame 2, and two first springs 10 are fixedly installed at the bottom of each housing. The bottom ends of the first springs 10 are fixedly connected to the top of the base plate 1. When the vibration motors 17 operate, they drive the vibration plate 7 to vibrate up and down, thereby causing the LED light source clamped on the clamping plate 6 to undergo vibration testing.

[0034] To improve the stability and effectiveness of the vibration, two second springs 12 are fixedly installed on one inner wall of each of the two boxes 9, with one end of each second spring 12 fixedly connected to one side of the vibrating plate 7. In addition, sliding grooves 11 are provided on both inner walls of the frame 2, and sliders are fixedly installed on one side of each of the two boxes 9. One side of each slider is slidably connected to the inner wall of the sliding groove 11 to further improve the stability of the boxes 9 during movement.

[0035] This application is used in the field of LED light source performance testing, but can also be used in other fields applicable to this application.

[0036] Example 2

[0037] refer to Figure 1-6 An improvement upon Embodiment 1: An LED light source performance testing device, which is used in the field of LED light source performance testing.

[0038] To facilitate observation of the LED light source's illumination during vibration, two fixing plates 4 are fixedly installed on both sides of the frame 2, and a black curtain 5 is provided on one side of each of the four fixing plates 4. The black curtain 5 can block external light interference and ensure the accuracy of the observation results.

[0039] One side of each of the four fixing plates 4 is glued with a Velcro hook side 13, and the four corners of the black curtain 5 are sewn with Velcro loops. By bonding the Velcro hook sides 13 and the Velcro loops, the black curtain 5 can be easily fixed to the fixing plate 4, and it is also easy to disassemble and clean.

[0040] However, as is well known to those skilled in the art, the working principle and wiring method of the vibration motor 17 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
