In motor vehicles the problem often arises that additional lighting is required in the cabin, in places where a voltage supply and the mounting thereof in the cockpit can not satisfactorily be resolved. A plug-in rechargeable lamp ( 1 ) has thus been developed, which may be plugged into the 12V or 24V cigarette lighter socket with a light diode ( 13 ) as light source, which gives a multi-application light source which may be used anywhere. The use of a light diode renders the lamp insensitive to shock effects and contributes to the lifespan thereof. The threshold voltage of the light diode ( 13 ) is optimally matched to the final discharge voltage of the applied accumulator cells, such that a fill discharge of the accumulators is practically excluded. |
