Electronic ballast |
摘要 |
An electronic ballast (EVG) is provided for operating at least one lamp (10), wherein a light sensor (20) for monitoring the brightness of a specific physical area (28) can be connected to the electronic ballast. A control arrangement (12) controls or regulates the brightness of the lamp (10) as a function of an actual brightness value delivered by the light sensor (20) and when the electronic ballast is put into operation automatically identifies whether a light sensor (20) is connected to the connection arrangement (18a, 18b). If no light sensor (20) is connected, the control or regulation of the brightness of the lamp (10) is effected as a function of externally supplied control information
