Abstract
The invention provides a sealing detection device used for detecting a sealing condition of a light-fixture casing. The detection device includes a vacuum machine, a windpipe assembly and a box body. The box body is used for loading water so as to enable the whole light-fixture casing to be immersed in the water of the box body. A first end of the windpipe assembly is in sealing communication with a venthole of the light-fixture casing. The vacuum machine is connected to a second end of the windpipe assembly in a sealing manner so as to enable the vacuum machine to be in communication with the internal part of the light-fixture casing. The vacuum machine is used for extracting air in the light-fixture casing so as to enable a first pressure in the light-fixture casing to be lower than an external pressure. Through determining whether water enters the light-fixture casing immersed in the water, the sealing condition of the light-fixture casing is determined. The sealing detection device and the detection method thereof realize an objective of convenient and rapid detection of the sealing of the light fixture and improvement of detection efficiency. The invention also provides a sealing detection method.
