Problems solved by technology

[0006] Due to the compressibility of gas, the above method is not sensitive to trace dew gas, it takes a long time to respond, and the test efficiency is low
Furthermore, even if dew is detected, the dew point cannot be judged, and it is impossible to carry out targeted re-covering and maintenance immediately.

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] refer to Figure 1 to Figure 6 , the first embodiment of the present invention is a device for testing the airtightness of lamps, including a water tank 101, a clamping part 102 is arranged on the top of the water tank 101, and a clamping part 102 is used for immersing the clamping part 102 in the water tank 101 and lifting it from the water tank 101. The lifting mechanism 103 also includes a pressurizing device (not shown in the figure, which can be connected with a tapered thread or other gas connection methods in the prior art) for connecting with the vent hole of the lamp to be tested.

[0030] The lifting mechanism 103 includes a lifting component 105 and a lifting motor 1031 , and the lifting motor 1031 drives the lifting component 105 through a screw rod 1032 / nut 1033 .

[0031] The device for testing the airtightness of lamps in this embodime...

Abstract

The invention relates to a lamp air tightness testing device, which comprises a water tank. A clamping part is arranged on the upper part of the water tank. The lamp air tightness testing device further comprises a lifting mechanism used for impregnating the clamping part into the water tank and lifting the clamping part from the water tank, and a pressurizing device for connecting with a vent hole of a lamp to be tested. The lamp air tightness testing device provided by the invention is quick in response, and can immediately represent the positions of dew points.

Description

technical field [0001] The invention relates to lighting technology, in particular to a lamp airtightness testing device for testing lamps in the field of lamp manufacturing. Background technique [0002] Outdoor lamps, such as LED street lamps, need to be waterproof and dustproof, so they need to be well sealed, otherwise the life of the lamps will be affected. [0003] In addition, because the lamps and lanterns will heat up and expand when they are working, if they are completely sealed, the internal air pressure will be too high when they are hot, and the parts may be damaged when they expand, and the most serious ones will explode. Therefore, a ventilation hole is provided on the luminaire. [0004] The entire luminaire must be completely sealed except for the vent hole, where a dustproof and waterproof structure will be set. When the luminaire leaves the factory, it is necessary to check whether the sealing is good, and it is necessary to find out the position where ...
