Description

Technical Field

[0001] This utility model relates to the technical field of xenon lamp test chambers, specifically a xenon lamp weather resistance test chamber. Background Technology

[0002] In the working circuit of a xenon lamp, the capacitor is a core component, and its performance directly affects the discharge stability and lifespan of the xenon lamp. In low-pressure applications such as external lighting for spacecraft and anti-collision lights for high-altitude drones, xenon lamps and their associated capacitors must withstand the harsh conditions of low-pressure environments. Therefore, the production process of xenon lamps and their associated capacitors requires testing under low-pressure conditions using a test chamber. However, existing xenon lamp test chambers still have some problems:

[0003] Commercially available xenon lamp test chambers have poor internal heat dissipation capabilities. When testing large batches of xenon lamps and their associated capacitors, excessive heat can easily accumulate inside the device, increasing the test variables under low-pressure conditions, making the tested products more susceptible to damage, and leading to distorted test results. Utility Model Content

[0031] The usage and advantages of this utility model: The working process of this xenon lamp weathering test chamber is as follows:

[0032] See Figures 1-7 The material rack 7 is used to place the xenon lamps and their matching capacitors to be tested. The user rotates the threaded fastening wheel 5 on the fastening rod 4.
