Abstract

A high-safety head lamp belongs to a cap lamp of miners used in downhole operation which is designed for solving the unreliable and unsafe sealing of cap lamp caused by unreasonable switch structure in current lithium cell semiconductor LED cap lamp. The utility model is provided with an encloser externally, on which a snap and a sunlight transparent board are positioned; a lithium cell, a control circuit board, a reflector and a semiconductor LED are sequentially arranged inside of the encloser. The lithium cell connects with an auxiliary lamp and a main lamp consisted by the semiconductor LED respectively through a circuit switching and a current-limiting resistance. The utility model is characterized in that the circuit switching is a magnetic switch consisted of a reed switch and a magnet control head which are correspondingly positioned inside and outside of the encloser respectively. The magnet control head moves translationally outside the encloser to control the shut and break of the two reeds in the reed switch inside of the encloser, the controlling unit and the controlled unit are in a totally separated condition thus the safety performance of the cap lamp is effectively improved.

Description

High safety miner's lamp

(1) technical field: the utility model relates to lighting, specifically belongs to be used for underground work and to be installed on mine lamp on the cap of ore deposit.

(2) background technology: be installed on the mine lamp on the cap of ore deposit in the underground work, be that the employing lead-acid accumulator is a power supply in the past, incandescent light bulb is a light source, this mine lamp volume is big, Heavy Weight does not meet environmental requirement, and incandescent light bulb temperature height, once fragmentation might cause gas explosion, use dangerous.For improving above-mentioned shortcoming, having occurred the employing lithium battery afterwards again is power supply, semiconductor light-emitting-diode (LED) is the mine lamp of light source, case is arranged outside it, the fore device light-passing board of case, sequence unit lithium battery, control circuit board, reflection shield in the case, the front device semiconductor light-emitting-diode of reflection shield.The output of the operating voltage of being supplied with by lithium battery is connected with semiconductor light-emitting-diode (LED) by contactor and current-limiting resistance.Contactor wherein is the push switch that is installed on the case side wall surface, so will perforate on case, push switch is installed in the perforate, and around switch, adopt the rubber parts sealing.Because the frequent push switch that uses, the sealing between itself and the case is easy to damage, and makes that the sealing condition in the case is unreliable, as situations such as short circuit generation spark, will become the hidden danger of gas accident.

(3) summary of the invention: cause the mine lamp sealing unreliable for solving above-mentioned mine lamp because construction of switch is unreasonable, have the problem of potential safety hazard, the applicant carries out architecture advances to contactor, and the security performance of mine lamp can effectively be improved.

The technical solution of the utility model is as follows:

Outside it case is arranged, the back-end device buckle of case, sequence unit lithium battery, control circuit board, reflection shield in the fore device light-passing board of case, case, the front device semiconductor light-emitting-diode of reflection shield; The positive voltage output end of described lithium battery is connected the negative voltage output head grounding of lithium battery by contactor and current-limiting resistance with the secondary lamp and the king light of partly leading the light emitting diode formation respectively; Described contactor is a magnetic switch, and an end of the tongue tube of magnetic switch is connected with the positive voltage output end of lithium battery respectively, and the other end is connected by the end of current-limiting resistance with described secondary lamp and king light respectively, the other end ground connection of described secondary lamp and king light; The tongue tube of magnetic switch is installed on the control circuit board respectively and the inboard of case, and displacement-type magnet control head is installed in the outside of case in the installation site of corresponding magnetic switch tongue tube.Described semiconductor light-emitting-diode is the light emitting diode that white light adds sodium yellow.

Because contactor is a magnetic switch; the switch block of magnetic switch is a tongue tube; dry spring tube device is in the inboard of mine lamp case; the operation control part part of magnetic switch---magnet control head is installed on the case outside; closing up or disconnecting of two reeds in the tongue tube controlled in the case in the translation outside case of magnet control head, and control piece and controlled product are in the state of isolation fully; avoid perforate on case, so effectively guarantee the sealing property of case.Even there is short-circuit spark to produce in the case, can not extend to outside the case yet, avoid gas accident.And two switch reeds of tongue tube are sealed in the glass shell security when further having improved conducting of switch reed and disconnection fully.Therefore security performance of the present utility model is effectively improved.
