ABSTRACT:
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.
