As the first level of lamp protection, the lamp shell plays an indispensable role in achieving waterproofing of the lamp. Therefore, in order to ensure that the lamp meets the waterproof level standard, sealing testing of the lamp shell during production is essential to reduce the influence of water, pollutants, dust, etc. during use of the lamp.Hirays Technology will provide application examples of the lamp housing sealing tester this time to provide suggestions for lamp housing sealing testing. The following is a demonstration of application examples.

1. Display of lamp casings tested by Hiraysi Technology

​ 

From the picture we can see that the lamp is a long strip and is a structural waterproof component.The lamp shell is a closed type. The light source is enclosed by a light-transmitting cover. The fixed part of the light-transmitting cover is tightly sealed and isolated from the outside world. The air inside and outside cannot circulate. There are no inflatable holes. Sealing glue and sealing rings are used as joint materials.

2. Key points of lamp shell sealing test

1. Due to the particularity of the lampshade structure, an indirect detection method is required.

2. Test within the specified pressure that the lampshade can withstand

3. In order to protect the lampshade shell, non-destructive testing must be carried out

4. This sealing test is a normal temperature test to avoid the impact of temperature on the sealing test.

3. Introduction to Hirays Technology’s lamp shell sealing test solution

Due to the special structure and curved shape of the lamp casing, Hirays Technology adopted an indirect detection method.First, customize the corresponding mold for the lamp shell and fix it to the tooling.This mold can effectively fix the curved lamp housing.Before testing, put the lamp shell into the mold, and then start the tester. When the upper and lower molds will be closed, a sealed space will be formed inside the mold, which isolates the external environment and prevents the shell from being damaged or affected during the test.The following is the sealing tester of Hirays Technology lamp housing.

Secondly, in terms of controlling the detection pressure, the precision pressure sensor built into the Hirays sealing tester strictly monitors the air pressure changes in the mold and controls the detection pressure within the detection pressure range that does not damage the lamp shell.Finally, after a series of calculations, the gas leakage value can be obtained. Based on the leakage value, the airtightness and IP waterproof level of the lamp housing can be detected.

In addition, this lamp housing sealing tester meets automated production standards.It has two pressure modes, "positive and negative", and 8 basic test modes, which can be selected individually or combined.It uses 24-bit A/D conversion, 32-bit CPU operation, and a completely independently developed industrial control operating system, combined with a full-touch human-computer interaction interface.Built-in RS232 serial port, RJ45 network port, USB communication interface, LTP external I/O control port, supports multiple communication protocols, enhances the operability of the equipment and improves the efficiency of the manufacturer's detection.The following is a diagram showing the detection details.

At present, Hirays Technology's outdoor lighting air tightness tester is used in: road lights, landscape lights (Chinese lanterns, fireworks lights, cherry blossom lights, etc.), lawn lights (stainless steel turf lights), underground lights, wall lights, outdoor spotlights, floodlights, wall washers and other lamp shells, circuit boards, wires, etc. for sealing testing.
