Description

Technical Field

[0001] The utility model belongs to the technical field of detection devices, and in particular relates to a device for detecting the service life of an LED filament. Background Art

[0002] Lamp life The life of a lamp depends mainly on the degree of burnout of the filament. After long-term use, the filament will gradually wear out due to thermal expansion and contraction, leading to the end of the lamp life. At present, LED lamp products will be powered on and lit after production to test the effectiveness of the filament life. Lamp lighting test is an important step in quality inspection, which can help us ensure the normal operation of the lamp. If the test time is too short, problems with the product may not be discovered, such as short life and poor luminous effect. Too long a test time will waste time and energy, and may also cause unnecessary damage to the lamp. Generally speaking, the lamp lighting test time should be controlled between 30 minutes and 1 hour.

[0003] Currently, LED lamp testing is carried out in a closed test chamber to prevent light source leakage. The operations of loading the LED lamps to be tested into the test chamber one by one and covering them with a lid are rather cumbersome, and the method of disassembling and installing multiple LED lamps deep inside the chamber is easily disturbed by the chamber. In addition, the replacement and disassembly steps of a batch of LED lamps are cumbersome, which results in a long waiting time between LED lamp testing. Utility Model Content
