A projection lamp is a special lamp that uses light to project images on a screen or wall. The principle is similar to showing a movie. It can project the pattern you want on the wall, floor, etc. for advertising, decoration, warning, etc.

And it is usually placed outdoors or exposed to the air, and waterproofing needs to be considered first.The main purpose is to solve the problem that the product fails when exposed to water or the circuit is damaged on rainy days, which affects the viewing experience.

thereforeProjector lamp air tightness testingIt is a necessary process.

According to the customer's requirements, the projector lamp needs to reach IP68 waterproof level. Hirays Technology used the following equipment and solutions for it:

Equipment used: Hirays HC classic seriesAir tightness testing equipment

Solution: Use indirect testing method, test pressure 15Kpa, inflation time 5s, voltage stabilization time 8s, test time 5s. The upper limit of leakage is 0.05Kpa.

Design the test mold according to the projector lamp, place the product to be tested on the mold, start the equipment, press down the upper mold and close the upper mold to seal the product, the instrument will detect the pressure change inside the mold through inflation, pressure stabilization, testing and other processes.When the leakage value is greater than the upper leakage limit, or the pressure does not reach the test pressure, the test result is automatically judged as NG.
