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

[0021] Please see Figures 1-3 This utility model provides a technical solution: a xenon lamp test chamber, including a chamber body 4, which is a sheet metal chamber with a painted outer surface for a neat and aesthetically pleasing appearance. A control panel 1, a PLC touch screen, is installed on the chamber body 4, using its internal PLC program to control the entire chamber. Inside the chamber body 4 is a stainless steel inner liner 11, with insulation cotton fixedly connected to each surface of the inner liner 11 to maintain a uniform temperature. Two air vents are located at the rear of the inner liner 11 to allow airflow and circulation, resulting in uniform temperature distribution. Temperature sensors 12 are installed on the sides of the inner liner 11 to sense the internal temperature and feed it back to the control panel 1 for precise temperature control. A rotating hub 8 is installed inside the chamber body 4, and a sample is mounted on the hub 8. The mounting plate 9 and the rotating hub 8 are configured with a three-layer structure (upper, middle, and lower). The sample mounting plate 9 fixes the sample with clips. The inner and outer sides of the rotating hub 8 are respectively equipped with an inner spray pipe 5 and an outer spray pipe 3. The inner spray pipe 5 and the outer spray pipe 3 are installed in the box 4 through a swivel fitting. Both the inner spray pipe 5 and the outer spray pipe 3 are equipped with nozzles 2, so that the spray direction is perpendicular to the sample direction, and the sample can be simulated to be sprayed with water both inside and outside. The box 4 is equipped with a sensor bracket 10, and a light sensor 6 is installed on the sensor bracket 10 to detect the light intensity of the xenon lamp. The rotating hub 8 is fixedly installed with a black plate temperature sensing component 14, which uses a PT100 platinum resistance thermometer as the temperature reference of the sample. The bottom of the inner side of the stainless steel inner liner 11 is equipped with a wiring bracket 7. The top of the rotating hub 8 is connected to a rotating mechanism through a flange 13.

[0022] The rotating mechanism includes a support frame 15. A geared motor 19 is fixedly mounted on one side of the support frame 15. The output shaft of the geared motor 19 is connected to a gear shaft 21 via a coupling 20. A driving bevel gear 22 is fixedly connected to the end of the gear shaft 21. A driven bevel gear 23 is provided on one side of the driving bevel gear 22. A through shaft is fixedly connected to the driven bevel gear 23. Two bearing seats 16 are installed on the outside of the through shaft. Bearings are installed inside the two bearing seats 16. The through shaft is rotatably connected to the bearing seats 16 through the bearings to ensure that the driving bevel gear 22 and the driven bevel gear 23 can mesh stably. The bottom end of the through shaft is fixedly connected to a flange 13. A conductive ring 17 is provided on the top of the support frame 15. Bolts 18 are provided on the conductive ring 17. The conductive ring 17 is a key component for realizing the transmission of electricity and signals between stationary and rotating parts. The moving wire on the hub 8 passes through the through shaft and is connected to the conductive ring 17 to avoid the wire from getting tangled.

[0023] A base 25 is fixedly connected to the center of the stainless steel inner liner 11. A lamp holder 24 is fixedly connected to the top of the base 25. A filter 26 is fixedly connected to the top of the lamp holder 24 through two connecting brackets 30. The filter 26 is made of specially customized glass and filters out wavelengths that do not meet the standard requirements. A lamp tube 27 is installed inside the filter 26. Water pipe connectors are provided at the top and bottom of the lamp tube 27. The lamp tube 27 is connected to a cooling water source through the water pipe connectors, which can cool the lamp tube 27. A fixing bracket 29 is fixedly connected to the wiring bracket 7. The end of the fixing bracket 29 is fixedly connected to the lamp tube 27 through screws 28. The wiring bracket 7 makes the wiring of the upper connector of the lamp tube 27 more neat and does not interfere with other parts.

[0024] During operation, the sample is fixed to the sample mounting plate 9 with clips, the door is closed, and the temperature and irradiance are set on the control panel 1. The test chamber automatically starts working, simulating the illumination conditions. After reaching the set cycle, the equipment automatically stops. The irradiance is monitored by the light sensor 6 and the signal is transmitted to the control panel 1 to control the irradiance of the lamp tube 27. The inner spray pipe 5 and the outer spray pipe 3 simulate water spraying on the sample inside and outside. The blackboard temperature sensing component 14 detects the temperature of the sample and uses it as a reference. The geared motor 19 drives the gear shaft 21 to rotate, which in turn drives the active bevel gear 22 to rotate. The active bevel gear 22 drives the driven bevel gear 23 to rotate, which in turn drives the through shaft to rotate. The through shaft drives the rotating hub 8 to rotate through the flange 13, which in turn drives the sample to rotate, thus automatically testing the sample. The overall structure is simple and easy to operate.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
