Sealing test, air tightness test and waterproof test cases of lighting

Due to the use environment and conditions of outdoor lighting, lighting manufacturers require that the sealing protection grade of outdoor lighting should reach IP, waterproof grade IP68, IP67, IP66, etc. But there are too many kinds of outdoor lighting, which can be divided into with wire and without wire, with air filling hole and without air filling hole. Therefore, for the manufacturer of this problem, we develop outdoor lighting air tightness detector.

In order to deal with the air tightness test of a variety of lighting, we divide the tester into three parts: tester, gas source and tooling. Because the tester, gas source and tooling are independent, we can equip different tooling according to the shape or details of the product to meet the detection requirements. In other words, as long as the manufacturer is equipped with qualified tooling for the air tightness test, the test can be carried out.

The airtightness test of this outdoor lighting by Harris technology uses compressed air as the test medium and the pressure drop test method to test the airtightness. The internal space of this equipment is only (1.5cc), and it is equipped with imported high-sensitivity pressure sensor, which provides the best environment for detection and achieves high-precision detection conditions.

When the detected lamp has an inflation hole, the air is supplied directly to the product inflation hole. After a certain period of time, the air supply source is cut off, and the pressure change of the product after inflation is monitored by the pressure sensor inside the instrument; If there is no air hole in the product, the mold is designed to package the product, and then the mold is used to quantitatively inflate the product surface, cut off the air source, and the pressure sensor of the internal instrument department is used to monitor the pressure change of the product after inflation, so as to detect the IP protection level of the lighting.

In addition, this outdoor lighting air tightness detector has reached the automatic production standard. It has "positive and negative" pressure forms and 8 Basic test modes, which can be selected or combined. Using 24 bit a / D conversion, 32-bit CPU operation, and fully independent development of industrial control operating system, with full touch human-computer interface. Built in RS232 serial port, RJ45 network port, USB communication interface, LTP external I / O control port, support a variety of communication protocols, enhance the operability of the equipment, only a few seconds to complete the test, improve the efficiency of the manufacturer's test.

At present, the air tightness detector of Harris technology is used in the air tightness detection of outdoor lighting: road lamp, landscape lamp (China lamp, fireworks lamp, cherry lamp, etc.), lawn lamp (stainless steel turf lamp), buried lamp, wall lamp, outdoor spotlight, projection lamp, wall washing lamp, etc.
