Automatic detection waterproof air tightness and inflation protection method of outdoor lamp

Abstract

The invention discloses an automatic detection waterproof air tightness and inflation protection method of an outdoor lamp. The automatic detection waterproof air tightness and inflation protection method of the outdoor lamp comprises the following steps that an air nozzle of an air extraction inflation mechanism and an air vent of the lamp are sealed; the lamp is filled with air and subjected toleakage detecting, the lamp is filled with the air through a compressor, and an air pressure difference value in the lamp is detected so as to judge the waterproof air tightness of the lamp; the lampis vacuumized and subjected to leakage detecting, and the lamp is vacuumized by the compressor to detect the air pressure difference value in the lamp so as to judge the waterproof air tightness of the lamp; the vacuumized lamp is filled with nitrogen; the nitrogen in a nitrogen tank is decompressed by a buffer gas tank first and then pressurized by the compressor, and the lamp with qualified waterproof air tightness is filled with nitrogen; and a vent hole is sealed with a waterproof joint. According to the automatic detection waterproof air tightness and inflation protection method of the outdoor lamp, the waterproof air tightness and inflation protection of the lamp are continuously carried out, the time consumption is short, the waterproof air tightness is detected under the positive pressure state and the negative pressure state of the lamp, the waterproof air tightness is quickly and effectively detected, and the detection accuracy is high; and the anti-oxidation of the lamp is good, and the service life of the lamp is prolonged.

Description

technical field [0001] The invention relates to the technical field of lamps, and more specifically relates to an automatic detection of waterproof and airtightness and an inflatable protection method for outdoor lamps. Background technique [0002] In recent years, the proportion of outdoor lamps in the lamp market has been increasing, and outdoor lamps have relatively high waterproof performance requirements. Usually, the waterproof performance of the lamps is tested before they leave the factory. The traditional detection method is to test the lamps. Water shower, and then manually observe whether there is water seepage inside the lamp, and then dry the qualified lamps, which is relatively time-consuming, inaccurate detection data, large footprint, and high cost; in addition, there is air inside the lamp, because normal air There will be a small amount of water in the lamp. After the lamp is used for a long time, the air in the lamp will produce water vapor with the tempe...

[0002] In recent years, the proportion of outdoor lamps in the lamp market has been increasing day by day, and outdoor lamps have relatively high requirements for waterproof performance. Usually, the waterproof performance of lamps is tested before they leave the factory. The traditional detection method is to test the lamps. Water shower, and then manually observe whether there is water seepage inside the lamp, and then dry the qualified lamps, which takes a relatively long time, has inaccurate test data, occupies a large area, and is expensive; in addition, there is air inside the lamp, because normal air There will be a small amount of moisture in the lamp. After the lamp is used for a long time, the air in the lamp will produce water vapor with the temperature change, which will damage the internal components and light source of the lamp, and shorten the life of the lamp.
