The invention relates to a light-emmiting component having organic layers, in particular to an organic light-emmiting diode. The first negative voltage supply line is connected to a level shift circuit, and is level-shifted to a voltage at a higher level relative to that of a second negative voltage which is output from a negative voltage generator circuit via a second negative voltage supply line. The fan also delivers airflow to a central bypass passage located inward of the compressor. The electromagnetic module includes a control circuit with one or more application specific integrated circuits for converting an input voltage from the dry battery to an operating voltage sufficient to power the light emitting diode. The first and second colors are different or the first and second shapes are different.
