Abstract

The invention belongs to the LED application field, and especially relates to an illumination circuit and explosion-proof lamp with a gas alarm function; the illumination circuit is respectively controlled by an illumination switch and a detection switch, so illumination and alarm functions can be singly used or combined for usage; the explosion-proof lamp having the illumination circuit with gas alarm function can be used for explosion-proof place inspection tours, so illumination problems in inspection can be solved, and combustible gas leakage detection and alarm function can be provided, thus further improving perception degree for dangers by work people; the work people can timely take prevention measures and inform other work people to flee from the dangerous place, thus ensuring work people life and public property safety, and reducing losses.

Description

technical field [0001] The invention belongs to the field of LED applications, in particular to a lighting circuit and an explosion-proof lamp with a gas alarm function. Background technique [0002] At present, due to improper pipeline or human operation in explosion-proof places such as coal mines and petrochemicals, it is easy to cause leakage of combustible gases such as gas. These combustible gases are colorless and odorless, and it is difficult to detect when leakage occurs. In this case, if you can't find out and take effective measures as soon as possible, serious safety accidents will occur, causing heavy losses to life and property. Contents of the invention [0003] In view of this, the purpose of the present invention is firstly to provide a lighting circuit with gas alarm function to solve the technical problem that the gas leakage in the explosion-proof place is not easy to be found in the prior art. This circuit can detect the gas concentration in the explos...
