METHOD FOR TESTING LED EXPLOSION-PROOF LAMP CHAMBER AND STRUCTURE THEREOF

摘要

A method for testing an LED explosion-proof lamp chamber and a structure thereof aim to be used on a LED explosion-proof lamp. The LED explosion-proof lamp includes a shell and a lighting unit connected to the shell. The shell includes at least one chamber, at least one test portion located at one side of the shell and a sealing assembly connected to the test portion. The test portion includes a test aperture which is sealed by the sealing assembly by screwing and communicates with chamber. The test aperture includes a first thread section and a second thread section connected to the first thread section. The sealing assembly includes a sealing ring, a fastener run through the sealing ring and screwed with the first thread section, and a mask member to cover the fastener and screw with the second thread section. Thus, through a test device and the sealing assembly the sealing efficacy or airtightness of the LED explosion-proof lamp can be secured.
