As we all know, the quality testing requirements for LED lighting products are constantly improving. The waterproof level is an important quality indicator. How to ensure the qualification rate of the waterproof level of the lamps can use air tightness testing equipment.

IP XThe second character code indicates the protection level against water ingress. IP 65 is dust-tight (no dust can enter) and water-spray-proof (water spray from all directions of the housing has no harmful effects).Noise) refer to GB4208-2008 IP66 means that the product is completely protected against the intrusion of foreign objects, and can completely prevent dust from entering, and can withstand the impact of violent waves orWhen there is a strong spray of water, the amount of water entering the appliance should not cause harmful effects.The IP67 waterproof test is to protect the cabinet from short-term immersion under standard pressure.When immersed in water for a short period of time, there should not be enough water to cause damage.There is a detailed description in GB 4208.This level is relatively highWaterproof grade.Generally, it is placed in a water depth of 1 meter and tested for half an hour.IP68 waterproof test is: guaranteed to work in 10 meters of water depth for 2 weeks.No water will enter; it can be put into 100 meters of water and tested for 12 hours of damage, and the product can still maintain good performance.

At present, the air tightness tester of Hiraysi is very stable for the grade detection of lamps. The detection principle is to do aA relatively sealed tool, then put the lamp into the tool, and then use the air tightness detector to inflate or exhaust the tool.Then the testerThe change in air pressure inside the device can determine the IP waterproof rating based on the air pressure difference.
