Description

Technical Field

[0001] This invention relates to the field of lighting fixture testing technology, specifically to a lighting fixture heat dissipation performance testing system and method. Background Technology

[0002] With the rapid development of solid-state lighting technology, LED lamps, with their significant advantages such as high luminous efficacy, long lifespan, energy saving, and environmental friendliness, have been widely used in commercial lighting, industrial lighting, road lighting, and smart home lighting. However, LED chips are extremely sensitive to temperature; their luminous efficacy, color temperature, color rendering index, and lifespan are all closely related to their junction temperature. Statistics show that for every 10°C increase in LED junction temperature, its lifespan decreases by approximately 50%, and the rate of light decay increases exponentially. Therefore, accurately assessing the heat dissipation performance of lamps has become a key technical aspect in ensuring product quality and extending their lifespan.

[0003] Traditional testing methods typically involve first securing the lamp under test with a clamp, then fixing multiple thermocouples or temperature sensors to the lamp surface for temperature monitoring. Because the sensors are positioned in a fixed location, they cannot comprehensively reflect the temperature distribution on the lamp surface, leading to insufficient accuracy and representativeness of the test results.

[0004] Therefore, a system and method for testing the heat dissipation performance of lighting fixtures are proposed. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a system and method for testing the heat dissipation performance of lamps, which solves the problem that traditional methods for testing the heat dissipation performance of lamps cannot fully reflect the surface temperature distribution of lamps, resulting in insufficient accuracy and representativeness of the test results.

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: This invention proposes a lamp heat dissipation performance testing system, including a frame, a lamp positioning component, and a testing component. The frame includes a base and a U-shaped frame fixed on the base. The lamp positioning component includes a support seat fixedly installed on the base. A support plate is slidably installed inside the support seat. Two symmetrically distributed positioning clamps are slidably installed on the top of the support plate. Guide blocks are fixedly connected to both ends of each positioning clamp. Inclined guide grooves are formed on both side walls of the support seat, and the guide blocks slide within the guide grooves. The detection assembly includes a first cylinder fixedly installed on the top of a U-shaped frame. A connecting plate is fixedly connected to the lower end of the first cylinder. A frame is fixedly connected to the bottom of the connecting plate. Abutment plates are fixedly connected to the bottom of both sides of the frame. A movable frame is slidably arranged at the bottom of the frame. A movable block is slidably installed at the bottom of the movable frame. A second cylinder is fixedly installed at the bottom of the movable block. A heat insulation plate is fixedly connected to the lower end of the second cylinder. A temperature sensor is installed at the bottom of the heat insulation plate. A drive assembly for driving the movable frame and the movable block to move is provided on the frame.

[0007] By adopting the above technical solution, during testing, the lamp under test is placed on the support plate and clamped and positioned by the lamp positioning component. The lamp under test is then turned on and allowed to operate normally for a period of time. The moving frame and moving block are moved by the drive component, allowing the temperature sensor to move freely above the lamp under test. When the temperature sensor moves to any random position, it can be moved by the extension of the second cylinder, which then drives the temperature sensor to contact the surface of the lamp under test, thereby detecting the temperature at any position on the surface of the lamp under test and achieving the effect of random detection.

[0008] Optionally, vertical grooves are provided on the other two side walls of the support base, and vertical sliders are fixedly connected to both sides of the support plate, with the vertical sliders slidably connected in the vertical grooves.

[0009] By adopting the above technical solution, when the support plate is subjected to force and descends, the vertical slider will slide along the vertical groove, which can guide the support plate and ensure its stability.

[0010] Optionally, the top of the support plate is provided with a transverse sliding groove, and the bottom of the positioning clamp is fixedly connected with a transverse slider, which is slidably connected in the transverse sliding groove.

[0011] By adopting the above technical solution, during the descent of the support plate, the positioning clamps are simultaneously guided by the guide groove and the transverse slide groove. The two positioning clamps slide relative to each other along the transverse slide groove while sliding along the guide groove, thereby clamping and positioning the lamp to be tested on the support plate.

[0012] Optionally, a flexible pressure sensor is provided on the clamping surface of the positioning clamp.

[0013] By adopting the above technical solution, the flexible pressure sensor will feed back the detected pressure signal to the controller in real time. When the pressure signal fed back by the flexible pressure sensor reaches a certain value, it indicates that the positioning clamp has clamped the lamp under test. At this time, the controller will control the first cylinder to stop, which can avoid the positioning clamp from using too much force to damage the lamp under test.

[0014] Optionally, a plurality of springs arranged in a matrix are fixedly connected to the inner bottom wall of the support base, and the upper ends of the springs abut against the support plate.

[0015] By adopting the above technical solution, after the test is completed, the controller can control the first cylinder to retract, so that the first cylinder drives the frame to rise through the connecting plate. As the contact plate gradually moves away from the support plate, the spring will push the support plate to rise and reset. As the support plate rises, the two positioning clamps will slide in the opposite direction along the transverse slide while sliding along the guide groove, releasing the clamping of the lamp under test.

[0016] Optionally, the drive assembly includes a transverse screw rotatably mounted within the frame and a motor for driving the transverse screw to rotate. A threaded sleeve is threaded onto the transverse screw, and the threaded sleeve is fixedly connected to the top of the movable frame.

[0017] By adopting the above technical solution, when the position of the temperature sensor is randomly adjusted, the motor can be started, causing the motor to drive the transverse screw to rotate, which in turn causes the screw sleeve to slide along the transverse screw, and the screw sleeve drives the moving frame to slide laterally.

[0018] Optionally, the drive assembly further includes a transverse guide rod fixedly installed within the frame, with a guide sleeve slidably sleeved on the transverse guide rod and the guide sleeve fixedly connected to the top of the movable frame.

[0019] By adopting the above technical solution, when the transverse screw rotates, the guide sleeve can slide along the transverse guide rod, which can play a transverse guiding role for the moving frame.

[0020] Optionally, the drive assembly further includes a reciprocating screw rotatably mounted on the bottom of the movable frame and a gear fixedly connected to one end of the reciprocating screw. A toothed plate is fixedly connected to one side of the frame, and the gear is meshed with the bottom of the toothed plate. The movable block is sleeved on the reciprocating screw and threadedly engaged with the reciprocating screw.

[0021] By adopting the above technical solution, when the moving frame moves, the moving frame will drive the gear to roll along the toothed plate, causing the gear to rotate. The rotation of the gear will drive the reciprocating screw to rotate, and the reciprocating screw will drive the moving block to slide longitudinally back and forth, thereby allowing the temperature sensor to move freely above the lamp under test.

[0022] Optionally, a controller is fixedly installed on one side of the U-shaped frame, and the first cylinder, the second cylinder, the temperature sensor, the flexible pressure sensor, and the motor are all electrically connected to the controller.

[0023] By adopting the above technical solution, the controller can control the first cylinder, the second cylinder, and the motor, and can also feed back the temperature and pressure signals detected by the temperature sensor and the flexible pressure sensor to the controller in real time.

[0024] This invention also proposes a method for testing the heat dissipation performance of lamps, comprising the following steps: S1. Place the lamp to be tested on the support plate. Control the first cylinder to start and extend through the controller. The first cylinder drives the frame to descend through the connecting plate. When the lower ends of the contact plates on both sides of the frame touch the support plate, the support plate will be lowered by force. Since the positioning clamps are guided by the guide groove and the transverse slide groove at the same time, the two positioning clamps will slide relative to each other along the transverse slide groove while sliding along the guide groove, thereby clamping and positioning the lamp to be tested on the support plate. S2. The flexible pressure sensor will feed back the detected pressure signal to the controller in real time. When the pressure signal fed back by the flexible pressure sensor reaches a certain value, it means that the positioning clamp has clamped the lamp to be tested. At this time, the controller will control the first cylinder to stop. S3. Turn on the lamp under test and allow it to operate normally for a period of time. Then, control the motor to drive the horizontal screw to rotate. The horizontal screw drives the screw sleeve to slide along the horizontal screw. The screw sleeve drives the moving frame to slide laterally along the horizontal guide rod. When the moving frame moves, it drives the gear to roll along the gear plate, causing the gear to rotate. The rotation of the gear drives the reciprocating screw to rotate. The reciprocating screw drives the moving block to slide longitudinally back and forth, allowing the temperature sensor to move freely above the lamp under test. When the temperature sensor moves to any position, the controller can start and extend the second cylinder, causing the second cylinder to drive the temperature sensor to contact the surface of the lamp under test, thereby detecting the temperature at any position on the surface of the lamp under test, achieving the effect of random detection. S4. The temperature signal detected by the temperature sensor will be fed back to the controller, and the temperature value will be displayed and recorded on the controller's screen. After the temperature of multiple locations on the surface of the lamp is randomly detected, the controller will plot the temperature curve, take the average value, and judge the heat dissipation performance of the lamp based on the average temperature.

[0025] (III) Beneficial Effects Compared with the prior art, the present invention provides a system and method for testing the heat dissipation performance of lamps, which has the following beneficial effects: 1. The present invention can randomly detect the surface temperature of the lamp under test, thereby obtaining multiple sets of data and taking the average value, making the test results more reliable; 2. This invention can automatically position the lamps while testing them, reducing manual operation, saving manpower, and improving testing efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0037] 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 invention, "a plurality of" means two or more unless otherwise explicitly specified.

[0038] This invention proposes a lighting fixture heat dissipation performance testing system, comprising a frame 1, a lighting fixture positioning assembly 2, and a testing assembly 3. The frame 1 includes a base 11 and a U-shaped frame 12 fixed on the base 11. The lighting fixture positioning assembly 2 includes a support base 21 fixedly mounted on the base 11. A support plate 22 is slidably mounted inside the support base 21. Two symmetrically distributed positioning clamps 23 are slidably mounted on the top of the support plate 22. Guide blocks 24 are fixedly connected to both ends of each positioning clamp 23. Inclined guide grooves 25 are formed on one side wall of the support base 21, and the guide blocks 24 slide within the guide grooves 25. Vertical sliding grooves 26 are formed on the other side wall of the support base 21. Vertical sliding grooves 26 are fixedly connected to both sides of the support plate 22. The vertical slider 27 is slidably connected within the vertical slide groove 26. The top of the support plate 22 has a horizontal slide groove 28. The bottom of the positioning clamp 23 is fixedly connected to a horizontal slider 29, which is slidably connected within the horizontal slide groove 28. When the support plate 22 is subjected to force and descends, the vertical slider 27 will slide along the vertical slide groove 26, which can guide the support plate 22 and ensure its stability. During the descent of the support plate 22, the positioning clamp 23 is simultaneously guided by the guide groove 25 and the horizontal slide groove 28. The two positioning clamps 23 will slide relative to each other along the horizontal slide groove 28 while sliding along the guide groove 25, thereby clamping and positioning the lamp to be tested on the support plate 22.

[0039] The positioning clamping block 23 is equipped with a flexible pressure sensor 210 on its clamping surface. The flexible pressure sensor 210 will feed back the detected pressure signal to the controller 13 in real time. When the pressure signal fed back by the flexible pressure sensor 210 reaches a certain value, it means that the positioning clamping block 23 has clamped the lamp to be tested. At this time, the controller 13 will control the first cylinder 31 to stop, which can prevent the positioning clamping block 23 from using too much force to damage the lamp to be tested.

[0040] Several matrix-distributed springs 211 are fixedly connected to the inner bottom wall of the support base 21. The upper end of the springs 211 abuts against the support plate 22. By setting the springs 211, after the test is completed, the controller 13 can control the first cylinder 31 to retract, so that the first cylinder 31 drives the frame 33 to rise through the connecting plate 32. As the abutting plate 331 gradually moves away from the support plate 22, the springs 211 will push the support plate 22 to rise and reset. As the support plate 22 rises, the two positioning clamps 23 will slide in the opposite direction along the transverse slide groove 28 while sliding along the guide groove 25, releasing the clamping of the lamp to be tested.

[0041] The detection component 3 includes a first cylinder 31 fixedly mounted on the top of the U-shaped frame 12. A connecting plate 32 is fixedly connected to the lower end of the first cylinder 31. A frame 33 is fixedly connected to the bottom of the connecting plate 32. Abutment plates 331 are fixedly connected to the bottom of both sides of the frame 33. A movable frame 34 is slidably mounted on the bottom of the frame 33. A movable block 35 is slidably mounted on the bottom of the movable frame 34. A second cylinder 36 is fixedly mounted on the bottom of the movable block 35. A heat insulation plate 37 is fixedly connected to the lower end of the second cylinder 36. A temperature sensor 38 is mounted on the bottom of the heat insulation plate 37. The frame 33 is equipped with… The drive assembly 39, used to drive the moving frame 34 and the moving block 35, turns on the lamp under test after it is positioned, allowing it to work normally for a period of time. Then, the drive assembly 39 can drive the moving frame 34 and the moving block 35 to move, allowing the temperature sensor 38 to move freely above the lamp under test. When the temperature sensor 38 moves to any random position, the second cylinder 36 can extend, causing the second cylinder 36 to drive the temperature sensor 38 to contact the surface of the lamp under test, thereby detecting the temperature at any position on the surface of the lamp under test and achieving the effect of random detection.

[0042] Specifically, the drive assembly 39 includes a transverse screw 391 rotatably mounted within the frame 33 and a motor 392 for driving the transverse screw 391 to rotate. A threaded sleeve 393 is threaded onto the transverse screw 391, and the threaded sleeve 393 is fixedly connected to the top of the movable frame 34. The drive assembly 39 also includes a transverse guide rod 394 fixedly mounted within the frame 33, with a guide sleeve 395 slidably sleeved on the transverse guide rod 394, and the guide sleeve 395 is fixedly connected to the top of the movable frame 34. The drive assembly 39 also includes a reciprocating screw 396 rotatably mounted at the bottom of the movable frame 34 and a gear 397 fixedly connected to one end of the reciprocating screw 396. A gear plate 398 is fixedly connected to one side of the frame 33, and the gear 397 is meshed with the bottom of the gear plate 398. Block 35 is sleeved on reciprocating screw 396 and threadedly engaged with reciprocating screw 396. By setting up drive assembly 39, when the position of temperature sensor 38 is randomly adjusted, motor 392 can be started, causing motor 392 to drive transverse screw 391 to rotate, causing transverse screw 391 to drive screw sleeve 393 to slide along transverse screw 391. Screw sleeve 393 drives moving frame 34 to slide laterally along transverse guide rod 394. When moving frame 34 moves, moving frame 34 will drive gear 397 to roll along tooth plate 398, causing gear 397 to rotate. The rotation of gear 397 drives reciprocating screw 396 to rotate, and reciprocating screw 396 drives moving block 35 to slide longitudinally back and forth, so that temperature sensor 38 can move freely above the lamp under test.

[0043] A controller 13 is fixedly installed on one side of the U-shaped frame 12. The first cylinder 31, the second cylinder 36, the temperature sensor 38, the flexible pressure sensor 210, and the motor 392 are all electrically connected to the controller 13. The controller 13 can control the first cylinder 31, the second cylinder 36, and the motor 392, and can also feed back the temperature and pressure signals detected by the temperature sensor 38 and the flexible pressure sensor 210 to the controller 13 in real time.

[0044] This invention also proposes a method for testing the heat dissipation performance of lamps, comprising the following steps: S1. Place the lamp to be tested on the support plate 22. Control the first cylinder 31 to start and extend through the controller 13. The first cylinder 31 drives the frame 33 to descend through the connecting plate 32. When the lower ends of the contact plates 331 on both sides of the frame 33 touch the support plate 22, the support plate 22 will be lowered by force. Since the positioning clamp 23 is guided by both the guide groove 25 and the transverse slide groove 28 at the same time, the two positioning clamps 23 will slide relative to each other along the transverse slide groove 28 while sliding along the guide groove 25, thereby clamping and positioning the lamp to be tested on the support plate 22. S2. The flexible pressure sensor 210 will feed back the detected pressure signal to the controller 13 in real time. When the pressure signal fed back by the flexible pressure sensor 210 reaches a certain value, it means that the positioning clamp 23 has clamped the lamp to be tested. At this time, the controller 13 will control the first cylinder 31 to stop. S3. Turn on the lamp under test and allow it to work normally for a period of time. Then, control the motor 392 through the controller 13 to drive the horizontal screw 391 to rotate. The horizontal screw 391 drives the screw sleeve 393 to slide along the horizontal screw 391. The screw sleeve 393 drives the moving frame 34 to slide laterally along the horizontal guide rod 394. When the moving frame 34 moves, it drives the gear 397 to roll along the toothed plate 398, causing the gear 397 to rotate. The rotation of the gear 397 drives the reciprocating screw 396 to rotate. The reciprocating screw 396 drives the moving block 35 to slide longitudinally back and forth, so that the temperature sensor 38 can move freely above the lamp under test. When the temperature sensor 38 moves to any position randomly, the controller 13 can control the second cylinder 36 to start and extend, so that the second cylinder 36 drives the temperature sensor 38 to contact the surface of the lamp under test, thereby detecting the temperature at any position on the surface of the lamp under test, achieving the effect of random detection. S4. The temperature signal detected by the temperature sensor 38 is fed back to the controller 13. The temperature value is displayed and recorded on the display screen of the controller 13. After the temperature of multiple locations on the surface of the lamp is randomly detected, the controller 13 plots the temperature curve, takes the average value, and judges the heat dissipation performance of the lamp based on the average temperature.

[0045] In summary, the lighting heat dissipation performance testing system and method can randomly test the surface temperature of the lighting fixture under test, thereby obtaining multiple sets of data and averaging them to make the test results more reliable.

When the moving frame (34) moves, the moving frame (34) will drive the gear (397) to roll along the toothed plate (398), so that the gear (397) generates The self-rotation of the gear (397) drives the reciprocating screw (396) to rotate, and the reciprocating screw (396) drives the moving block (35) to slide longitudinally back and forth, so that the temperature sensor (38) can move freely above the lamp to be tested. When the temperature sensor (38) moves randomly to any position, the controller (13) can control the second cylinder (36) to start and extend, so that the second cylinder (36) drives the temperature sensor (38) to contact the surface of the lamp to be tested, thereby detecting the temperature at any position on the surface of the lamp to be tested, achieving the effect of random detection. S4. The temperature signal detected by the temperature sensor (38) will be fed back to the controller (13). The temperature value will be displayed and recorded on the display screen of the controller (13). After randomly detecting the temperature at multiple locations on the surface of the lamp under test, the controller (13) will draw a temperature curve, take the average value, and judge the heat dissipation performance of the lamp based on the average temperature.
