Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lighting testing technology, specifically relating to a lighting lifespan testing platform. Background Technology
[0002] Lighting life testing is a process that assesses how long a lighting fixture can operate continuously under normal usage conditions. This testing is crucial for ensuring the quality, performance, and safety of lighting fixtures. By simulating real-world usage environments and conditions, such as temperature variations, power switching frequency, and vibration, potential defects and weaknesses in the fixture can be effectively identified. Furthermore, life testing helps manufacturers optimize product design, improve energy efficiency, reduce costs, and ensure product compliance with relevant regulations and standards. Ultimately, this not only enhances the product's market competitiveness but also improves the user experience and satisfaction.
[0003] A known authorized patent application with application number 202222746176.4 discloses an automated lamp aging test bench: It includes a base and a horizontal plate. The horizontal plate is horizontally supported on the upper surface of the base by support rods at the four corners between the horizontal plate and the base, and the horizontal plate is parallel to the base surface. An industrial control computer is installed in the center of the horizontal plate surface. Five test slots are evenly distributed on the bottom surface of the horizontal plate, and lamp holders are installed inside the test slots. This utility model's technical solution, by setting five test slots with lamp holders below the horizontal plate and connecting them to light bulbs, allows four of the test slots to be covered and locked with four shields of different ventilation effects. This allows the light bulbs to undergo aging tests under different ventilation environments, and the temperature during the test can be monitored by a temperature sensor to determine the specific working time of the light bulb and obtain its lifespan, thus achieving the purpose of automated testing.
[0004] However, in implementing the relevant technologies, the following problems were found in the above technical solutions: when in use, only the service life test can be carried out under specific scenarios, but there is no ability to test under high temperature and high humidity conditions, which makes the test results relatively one-sided and cannot be used as a reference for the final service life determination. Therefore, a lamp service life test bench is proposed to solve the above problems. Utility Model Content

[0025] Example 1
[0026] Please see Figure 1 -4. A lamp life test bench, comprising: a test chamber 1, a base chamber 2, a blower 17, a heating tube 5, a humidifier 18 and a lamp base 20, wherein a connecting plate 3 is fixedly connected to the upper surface of the base chamber 2, and the test chamber 1 is slidably connected to the inner wall of the connecting plate 3.
[0027] The upper surface of the base box 2 is provided with a fixing hole 22, and a fixing arm 21 is fixedly connected to the outer wall of the lamp base 20. The fixing arm 21 is snapped into the inner wall of the fixing hole 22.
[0028] Heating tube 5 is fixedly connected to the inner wall of test chamber 1;
[0029] Humidifier 18 is fixedly connected to the outer wall of the bottom box 1. Humidifier tube 15 is fixedly connected to the output end of humidifier 18. A second connecting sleeve 14 is sleeved on the outer wall of the other end of humidifier tube 15. The second connecting sleeve 14 is threadedly connected to test box 1.
[0030] The technical solution provided in this embodiment is as follows: If a high temperature and high humidity environment is selected for testing, the correct lamp base 20 is first selected, and the lamp base 20 is inserted into the through hole opened in the bottom box 2. After insertion, the lamp base 20 is rotated. When the fixing arm 21 falls into the fixing hole 22, the installation is completed. Then the bulb is installed. Next, the test box 1 is pushed in. After the test box 1 is blocked by the rear plate 6, the pushing is stopped, and the limiting insert 4 is inserted into the through hole opened in the connecting plate 3. Then, the humidifying tube 15 is connected to the test box 1 through the second connecting sleeve 14. Then, the host 19 sets the required temperature and humidity. Then, the heating tube 5 and the humidifier 18 are turned on. The humidified air output by the humidifier 18 is input into the test box 1 through the humidifying tube 15. Then, the temperature sensor 9, the brightness tester 10 and the humidity tester 11 are observed to monitor the temperature and humidity in real time. After the brightness tester 10 detects that the brightness of the bulb has decreased to a certain extent, the host records the time.
[0031] Example 2
[0032] Based on Embodiment 1, in this embodiment: the blower 17 is fixedly connected to the outer wall of the bottom box 2, the output end of the blower 17 is fixedly connected to the air duct 12, the inside of the air duct 12 is fixedly connected to the hot air block 16, the outer wall of the end of the air duct 12 is sleeved with the first connecting sleeve 13, and the first connecting sleeve 13 is threadedly connected to the outer wall of the test box 1.
[0033] The technical solution provided in this embodiment is as follows: If a high-temperature environment is selected for testing, after inserting the limiting insert 4, the air duct 12 and the test box 1 are connected through the first connecting sleeve 13. Then, the host 19 presets the temperature and monitors the time. Next, the sealing plate 7 is pulled out, and then the blower 17 and the hot air block 16 are started. The hot air block 16 heats the air output by the blower 17 and inputs it into the interior of the test box 1 through the air duct 12. After the hot air is input for a period of time, the residual air with a lower temperature inside is discharged. Then, the sealing plate 8 is reinserted, and the temperature sensor 9 and the brightness tester 10 are observed to keep the temperature at the preset value. After the brightness decays to a certain extent, the host 19 records the time.
[0034] Furthermore, a rear plate 6 is fixedly connected to the upper surface of the connecting plate 3, and a limit plate 4 is inserted into the interior of the connecting plate 3.
[0035] Specifically, the rear plate 6 and the limiting plate 4 can fix the position of the detection box 1 to prevent the detection box 1 from accidentally falling off during the detection.
[0036] Furthermore, a ventilation window 7 is provided on the upper surface of the test chamber 1, and a sealing plate 8 is inserted into the upper surface of the test chamber 1, with the sealing plate 8 located directly above the ventilation window 7.
[0037] Specifically, the ventilation window 7 allows the blower 17 to quickly expel the residual air inside the test chamber 1 when it starts up, and the sealing plate 8 can simply seal the test chamber 1 after the air is expelled, making the temperature rise faster.
[0038] Furthermore, a temperature sensor 9 is fixedly connected to the upper surface of the test chamber 1, a brightness tester 10 is fixedly connected to the upper surface of the test chamber 1, and a humidity tester 11 is fixedly connected to the upper surface of the test chamber 1.
[0039] Specifically, the setup of multiple detectors allows for timely and accurate display of the conditions inside the detection chamber, enabling a faster understanding of the environment inside detection chamber 1.
[0040] Furthermore, the main unit 19 is fixedly connected inside the bottom box 2.
[0041] Specifically, the main unit 19 can control the humidifier 18, the blower 17, and the hot air block 16, and monitor the data of the three detectors in real time. After the brightness detector 10 detects that the brightness of the bulb has decayed to a certain extent, it records the time in a timely manner.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
