Before the car lamp air tightness test replaced the water test, the car lamp waterproof test was not yet mature in China, and many air tightness tests were in vain, including the leak detectors used. Most small and medium-sized enterprises used leak detectors that were just decorations and did not play any role in actual testing. Today we first look at how to use the Heruis air tightness test on automobile lamps:

There are two main types of car light air tightness testing. One type of car light has its own inflatable port, and the other is a completely sealed light that cannot be inflated inside. The test must use an air tightness tester with high repeatability. You can consult Shenzhen Hiraysi Air Tightness Testing Instrument Co., Ltd. for communication;

1. For lamps with an inflatable port, we can directly connect the Test port of the air tightness tester to the inflatable port of the lamp, block the remaining holes with high-sealing plugs, and then inflate, stabilize and test the entire system, read the data directly through the air tightness tester, and determine the results;

2. For completely sealed lamps, the above method cannot be used at all. Then, we can use the air tightness tester in the sealed test mode to put the lamp into a closed cavity. In the first stage, the inside of the air tightness tester is filled with gas at a certain pressure and the gas is released into the entire system., determine whether there is a very large leakage in the lamp. We call this process to determine whether there is a large leakage. If there is no large leakage, then enter the second stage to inflate, stabilize and test the entire system. The equipment will test and obtain the result value to determine whether the lamp has leakage and obtain the leakage rate of the lamp;

At present, the requirements of the lighting industry are getting higher and higher, and more customers require lamps to meet a certain waterproof level. Traditional water testing is completely unable to adapt to current mass production testing. As the most cost-effective air tightness testing instrument, the air tightness tester is suitable for large-scale online pick-up.Shenzhen Hirays Automation Technology Co., Ltd. has rich experience in precision air tightness testing instruments for lamps and lanterns. While providing air tightness testing solutions and equipment for lamps for a long time, it also has a very professional testing method for waterproof testing of lamps and lanterns. If you have any relevant information, you can contact us for communication.
