Work-place light with fluorescent lamp and low-voltage (LV) lamp

The work light (13) includes a fluorescent lamp (11) and a low-voltage lamp (12), which are alternately operated from a common voltage source. The low-voltage lamp is a halogen lamp (12), and the common voltage source is an AC voltage line supply (10). First devices, preferably a bridge rectifier (D...

Beschreibung
Zusammenfassung:	The work light (13) includes a fluorescent lamp (11) and a low-voltage lamp (12), which are alternately operated from a common voltage source. The low-voltage lamp is a halogen lamp (12), and the common voltage source is an AC voltage line supply (10). First devices, preferably a bridge rectifier (D2-D5) connected to a line supply (10) and a coupled capacitor (Cl), are provided for transforming the line supply AC voltage into a DC voltage. Second devices are provided for transforming the DC voltage into an AC voltage with increased frequency with respect to the line supply. The voltages for the operation of the fluorescent lamp and the halogen lamp are alternatively derived from the produced AC voltage.
