Abstract (en)

[origin: EP1107422A2] The method involves changing over to a replacement electricity supply in the event of a supply fault and changing over to the normal supply after the fault is removed. A buffer storage device provides electrical energy for the operation of the discharge lamp (16) during the changeover. The buffer storage device is a capacitor that is at least partly discharged during the changeover. Independent claims are also included for the following: a light, especially for medical applications.
