In the case of glow lamps for underground mining operations, this regulation is not mandatory, but it is here especially in mines exposed to firedamp the replacement of incandescent lamps on luminaires is only permitted when the lighting system is de-energized, which - as has been shown in practice has - but is not followed in all cases.

However, dismantling lighting systems are already known in which each lamp is assigned a special closed-circuit contact as a switching element in such a way that when the lamp is opened, the closed-circuit is interrupted and the ^{entire "B} " lighting circuit is automatically switched off on all poles. These types of lighting systems in mining operations have the disadvantage that the entire mining lighting is switched off for the duration of the replacement of an incandescent lamp and, in mechanized operations, coal extraction is then suspended until it is switched on again.

According to the innovation, it is proposed that every lamp - in particular Strebleuohten for mining operations - with a locking bracket, , i.e. to be provided with a two-pole pressure contact as a switching element « When a luminaire is opened, the Sinbaufaasung automatically becomes all-pole switched off, whereas the others connected to the same circuit Lights remain switched on. The replacement of the incandescent lamp takes place in the de-energized state of the Installation bevel of this luminaire. The lock switch of this Leuohte can either be built into the luminaire itself or outside screwed onto the luminaire, housed in a special protective housing. The latter appears for the sake of better Cable routing within the luminaire for spatial reasons

more advantageous »because such lighting systems are in dismantling areas a plurality of light stalls consist of each other and the source of comfort through a four-core main cable three phase conductors and a core connected to earth potential are · Spazial lines are also being laid »in those * next to the phase conductors within the protective conductor ^ Peraspreohadern laid in isolation are »which means for the Cable laying within each Leuohte even more tree is required.

The figure rises two exemplary embodiments of the arrangement dea interlocking switch on a power supply unit. According to Fig. 1, the locking lever is horizontally in a housing bore inserted from the outside »with the actuator in a special Attachment chain is screwed around the luminaire housing

According to Fig. 2, the interlock switch is vertical in a sprue hook of the Leuohten housing used

The luminaire housing 1 has reinforcements 2 and 3 in addition to the Vf and for sewing on entry nozzles for the lines and the The same wall reinforcement (not shown) for a quiet atros signal contact has a sprue cam 4 or 5 »in this crouch the Verrlegelungaaohalter used and gladly * Fig. 2 with a tubular hatch 7 screwed tight with the interposition of a seal 8 ο Or, as shown in Fig. 1, the locking switch 6 can be inserted horizontally into the housing bore from the outside »with the actuating element in a special add-on housing 9 led aa luminaire housing is flanged
