Description
Technical Field
[0001] This utility model relates to the field of LED lamp heat dissipation testing, specifically a device for testing the heat dissipation performance of an LED lamp structure. Background Technology
[0002] LED lights, with their significant advantages such as low energy consumption, long lifespan, and environmental friendliness, have been widely used in lighting, displays, and other fields. As the power density of LED lights continues to increase, the heat generated during operation also increases. Excessive temperature can accelerate the light decay of LED chips, degrade color rendering, and even directly affect the lifespan and safety performance of the lamp body. Therefore, heat dissipation performance has become one of the core indicators for evaluating the quality of LED light products. Accurate testing of the heat dissipation performance of LED lights is a crucial step in product development, production quality control, and market access.
[0003] Existing LED lamp heat dissipation performance testing devices typically employ an open testing platform, where the LED lamp is directly placed on a conductive support and powered on. Temperature sensors collect the surface temperature of the lamp or the surrounding environment to assess the heat dissipation effect. However, open testing devices have significant drawbacks: firstly, external airflow can interfere with the temperature field of the testing area, leading to large fluctuations in temperature data and failing to accurately reflect the actual heat dissipation performance of the LED lamp, resulting in poor accuracy of the test results; secondly, they have poor adaptability. When adapting to LED lamps of different models and interfaces, it is necessary to disassemble and rewire, which is cumbersome and prone to damaging the wiring, resulting in poor compatibility and versatility. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a heat dissipation performance testing device for LED lamp structures to address the deficiencies of the prior art.
[0005] The purpose of this utility model is achieved through the following technical solution: a heat dissipation performance testing device for an LED lamp structure, comprising a transparent housing, a conductive testing platform disposed within the transparent housing, a lamp holder mounted on the conductive testing platform, the lamp holder matching the LED lamp to be tested, the positive and negative terminals of the lamp holder being connected to a first straight male plug and a first straight female socket respectively via wires, a power plug disposed outside the transparent housing, the power plug being connected to a second straight male plug and a second straight female socket via power wires, the second straight female socket being plugged into the first straight male plug, and the first straight female socket being plugged into the second straight male plug, a temperature detection mechanism disposed within the transparent housing, the temperature detection mechanism including a temperature sensor arranged within the transparent housing.
[0006] Furthermore, a circular hole is provided on the side wall of the transparent box, through which the power cord passes into the transparent box, and a sealing rubber ring is fixed inside the circular hole.
[0007] Furthermore, the temperature detection mechanism also includes a horizontal lead screw, a detection arm, and a guide rod. The horizontal lead screw is rotatably connected to the transparent housing. One end of the detection arm has a threaded hole, and one end of the horizontal lead screw is threaded into the threaded hole. The temperature sensor is installed at the end of the detection arm away from the horizontal lead screw. One end of the guide rod is connected to the detection arm, and the other end moves through the transparent housing.
[0008] Furthermore, the detection arm includes a support arm and a lifting arm, the threaded hole is formed on the support arm, and the guide rod is connected to the support arm. The lifting arm is mounted on the support arm, the temperature sensor is mounted on the lifting arm, and the lifting arm has the degree of freedom to move along the height direction of the transparent box.
[0009] Furthermore, a vertical lead screw is rotatably connected to the top of the support arm, the lifting arm is threaded onto the vertical lead screw, a guide shaft is fixedly connected to the top of the support arm, the guide shaft moves through the lifting arm, and a cross groove is formed at the top of the vertical lead screw.

[0014] The beneficial effects of this utility model are:
[0015] 1. By creating a closed testing space with a transparent enclosure, interference from external airflow on the temperature field of the testing area is avoided. This ensures that the temperature data collected by the temperature sensor accurately reflects the actual heat dissipation status of the LED, significantly reducing fluctuations in the test data. This provides an accurate and reliable basis for heat dissipation performance evaluation, meeting the stringent requirements for testing accuracy in product development, production quality control, and market access.

Detailed Implementation
[0022] Example 1
[0023] like Figures 1 to 4As shown, a heat dissipation performance testing device for an LED lamp structure includes a transparent housing 1. A conductive testing platform 2 is installed inside the transparent housing 1, and a lamp holder 3 is mounted on the conductive testing platform 2. The lamp holder 3 is matched with the LED lamp to be tested. The positive and negative terminals of the lamp holder 3 are connected to a first straight male plug 4 and a first straight female socket 5 respectively via wires. A power plug 6 is installed outside the transparent housing 1. The power plug 6 is connected to a second straight male plug 7 and a second straight female socket 8 via power wires. The second straight female socket 8 is plugged into the first straight male plug 4, and the first straight female socket 5 is plugged into the second straight male plug 7. A temperature detection mechanism is installed inside the transparent housing 1, including a temperature sensor 9 arranged inside the transparent housing 1. A matching lamp holder 3 is selected according to the model of the LED lamp to be tested, and the lamp holder 3 is installed inside the transparent housing 1. Different lamp holders 3 are equipped with a first straight male plug 4 and a first straight female socket 5. After the lamp holder 3 is assembled, the first straight male plug 4... The LED light is powered by connecting the second straight female socket 8 and the second straight male plug 7 to the first straight female socket 5 inside the transparent enclosure 1, and finally by connecting the power plug 6 to the power source. This allows for the installation of the corresponding lamp holder 3 according to the LED light model, eliminating the need to disassemble and rewire the wires, effectively preventing circuit damage, simplifying the operation process, and improving the versatility and efficiency of the testing device. The temperature sensor 9 provides feedback on the surface temperature of the LED light, detecting the temperature in real time and obtaining a time-temperature relationship graph, which reflects the heat dissipation performance of the LED light. The transparent enclosure 1 forms a closed testing space, preventing external airflow from interfering with the temperature field of the testing area, ensuring that the temperature data collected by the temperature sensor 9 accurately reflects the actual heat dissipation state of the LED light, significantly reducing the fluctuation range of the testing data, providing accurate and reliable basis for heat dissipation performance evaluation, and meeting the stringent requirements for testing accuracy in product development, production quality control, and market access.
[0024] Furthermore, a limiting post 24 is fixed at the bottom of the conductive testing platform 2, and a rectangular groove is provided on the inner bottom wall of the transparent box 1. The limiting post 24 is adapted to the rectangular groove. The conductive testing platform 2 can be quickly installed and disassembled through the cooperation of the limiting post 24 and the rectangular groove, which makes it convenient to replace the corresponding lamp holder 3 according to the model of the LED light.
[0025] Example 2
[0026] Based on Example 1, such as Figure 1 and Figure 4As shown, the transparent box 1 has an opening at the top. An annular support platform 20 is fixed to the inner wall of the transparent box 1. A cover 21 is mounted on the annular support platform 20. An annular sealing ring 22 is fixed to the bottom of the cover 21, and the annular sealing ring 22 contacts the annular support platform 20. Multiple limiting rods 23 are rotatably connected to the top of the transparent box 1. The limiting rods 23 contact or separate from the cover 21 by rotation. When the limiting rods 23 contact the top surface of the cover 21, the annular sealing ring 22 is in a compressed deformation state. The opening at the top of the transparent box 1 facilitates the replacement of the lamp holder 3. The cover 21 is used to seal the opening at the top of the transparent box 1. The opening is used to create a closed detection space inside the transparent box 1. Specifically, the limiting rod 23 is rotated to separate the limiting rod 23 from the cover 21. At this time, the cover 21 is no longer blocked by the limiting rod 23, and the lamp holder 3 can be replaced by removing the cover 21. After replacement, the cover 21 is placed on the annular support platform 20, and then the cover 21 is pressed down. Then the limiting rod 23 is rotated to contact the top surface of the cover 21, completing the installation of the cover 21. At this time, the annular sealing ring 22 is in a compressed state, so that a good seal is formed between the cover 21 and the annular support platform 20, ensuring the accuracy of the detection data.
[0027] Example 3
[0028] Based on Example 2, such as Figure 1 and Figure 2 As shown, a circular hole 10 is provided on the side wall of the transparent box 1. The power cord passes through the circular hole 10 into the transparent box 1. A sealing rubber ring 11 is fixed inside the circular hole 10. The second straight male plug 7 and the second straight female socket 8 are arranged inside the transparent box 1, and the power plug 6 is arranged outside the transparent box 1. The power cord is arranged through the circular hole 10, and the gap between the circular hole 10 and the power cord is sealed by the sealing rubber ring 11.
[0029] Example 4
[0030] Based on Example 3, such as Figures 1 to 3As shown, the temperature detection mechanism also includes a horizontal lead screw 12, a detection arm 13, and a guide rod 14. The horizontal lead screw 12 is rotatably connected to the transparent housing 1. One end of the detection arm 13 has a threaded hole 15, and one end of the horizontal lead screw 12 is threaded into the threaded hole 15. The temperature sensor 9 is installed at the end of the detection arm 13 away from the horizontal lead screw 12. One end of the guide rod 14 is connected to the detection arm 13, and the other end moves through the transparent housing 1. The detection arm 13 includes a support arm 16 and a lifting arm 17. The threaded hole 15 is formed in the support arm 16. Above, guide rod 14 is connected to support arm 16, lifting arm 17 is installed on support arm 16, temperature sensor 9 is installed on lifting arm 17, lifting arm 17 has the freedom to move along the height direction of transparent box 1, vertical screw 18 is rotatably connected to the top of support arm 16, lifting arm 17 is threaded on vertical screw 18, guide shaft 19 is fixedly connected to the top of support arm 16, guide shaft 19 moves through lifting arm 17, and a cross groove is opened on the top of vertical screw 18. Since LED lamps are divided into lamp tubes and bulbs... Secondly, to make the test results more accurate, the temperature sensor 9 needs to contact the LED light for testing. For different models of LED lights, the temperature detection mechanism can adjust the height and horizontal position of the temperature sensor 9 so that the temperature sensor 9 can contact and test different models of LED lights. Specifically, after the lamp holder 3 is installed, a screwdriver is used on the cross groove of the vertical lead screw 18 to rotate the vertical lead screw 18. Under the action of the guide shaft 19, the lifting arm 17 moves linearly along the axis of the vertical lead screw 18, thereby adjusting the height position of the temperature sensor 9. Then, the horizontal lead screw 12 is rotated, and under the action of the guide rod 14, the support arm 16 moves along the axis of the horizontal lead screw 12 to adjust the horizontal position of the temperature sensor 9. The two work together to make the temperature sensor 9 contact the surface of the LED light for temperature detection, which can more accurately reflect the working temperature of the LED light and more accurately reflect the heat dissipation performance of the LED light. After the position of the temperature sensor 9 is adjusted, the cover 21 can be installed to carry out the testing operation. In practice, the end of the horizontal lead screw 12 away from the support arm 16 extends to the outside of the transparent box 1, making it convenient to manually rotate the horizontal lead screw 12. The wire of the temperature sensor 9 passes through the wiring hole on the transparent box 1. A sealing ring is installed in the wiring hole to seal the gap between the wiring hole and the wire, so as not to affect the closed detection environment inside the transparent box 1.
