Mine downhole gapless power failure emergency lighting circuit

Abstract

The invention relates to a mine downhole gapless power failure emergency lighting circuit. The safety of workers in a downhole can be seriously affected after lighting lamps stop working due to the fact that mine downhole power failure occurs or circuit failure occurs. The mine downhole gapless power failure emergency lighting circuit comprises a lighting lamp H1, one end of the lighting lamp H1 is connected to a second pin of a load transducer LSE, a third pin of the load transducer LSE is connected to an emitting electrode of a triode VT and a positive electrode of a direct-current power source E, a fourth pin of the load transducer LSE is connected to a resistor R1, a fifth pin of the load transducer LSE is connected to a resister R2, a base electrode of the triode VT is connected after the resister R1 and the resister R2 are switched on, a collector electrode of the triode VT is connected to a relay J, the relay J is connected to the negative electrode of the direct-current power source E, and the direct-current power source E is connected with a contact of the relay J and a direct current lamp H2 in parallel. The mine downhole gapless power failure emergency lighting circuit can enables a circuit of an emergency light source to be switched on by using the load transducer when a power failure or a circuit failure occurs, and the switch of the lighting lamp and the emergency light source is nearly ceaseless.

Description

technical field [0001] The invention relates to an emergency lighting circuit, in particular to an emergency lighting circuit for power failure without gaps in underground mines. Background technique [0002] Mine roadway lighting is the lifeline to ensure the normal production of mines, and it is also one of the main measures for mine safety production. However, due to the environment and use status of mine roadways, there are many inconveniences in mine roadway lighting. Once the downhole power failure or circuit failure causes the lighting to stop working, it will seriously endanger the safety of the staff in the downhole. Contents of the invention [0003] The object of the present invention is to provide an emergency lighting circuit for emergency lighting without gaps in underground mines that can quickly provide emergency light sources in the event of power failure or circuit failure. [0004] The technical scheme adopted in the present invention is: ...
