Problems solved by technology

[0002] Most of the well-known underground indicator lights are ordinary incandescent lamps or LED lights, which are extremely easy to explode in the flammable and explosive environment underground.
And when used for indicator lights on hydraulic supports or other downhole equipment, its shock resistance and impact resistance are also extremely poor, which cannot meet the needs of downhole operations

Abstract

The invention discloses a mining signal lamp comprising a light-emitting diode, the light-emitting diode is arranged in a cylindrical shell, pouring sealant is placed in the cavity at the wire inlet end of the light-emitting diode in the cylindrical shell, the pouring sealant connect the light-emitting diode and the cylindrical shell fixedly; the external surface of the cylindrical shell is connected with a fastening nut in threads. The invention has the advantages of simple structure and low cost; when in use, not only the brightness is high, but also the properties of anti-explosion and anti-collision required by operation in the pit under the protection of cylindrical shell and pouring sealant.

Description

Technical field [0001] The present invention relates to a signal indicator lamp, in particular to a signal indicator lamp for mining. Background technique [0002] Known underground mine indicator lights are mostly ordinary incandescent lamps or LED lights, which are extremely explosive in an inflammable and explosive environment underground. And when used for indicator lights on hydraulic supports or other downhole equipment, its seismic and impact resistance performance is also extremely poor, which cannot meet the needs of downhole operations. Summary of the invention [0003] The purpose of the present invention is to provide a signal indicator lamp for mines with large brightness, explosion-proof and impact resistance. [0004] In order to achieve the above objectives, the present invention can adopt the following technical solutions: [0005] The mine signal indicator of the present invention includes a light-emitting diode, the light-emitting diode is arranged in a cylindrica...
