摘要： For the video recording of a field illuminated by a lamp, especially a surgical lamp, where at least one light beam for illuminating the field emerges from a light exit area of a lamp housing in the direction of a predetermined housing axis, the optical axis of a video camera mounted with freedom to swivel a certain distance away from the exit point of the light beam is shifted automatically by a positioning element until the axis at least approximately intersects the light beam in the area of the illuminated field. The positioning element is driven by signals from a control unit. The video camera is preferably shifted in a stepwise manner. The distance to the illuminated field is determined by the fine focusing of the camera by the autofocus function, and then signals are transmitted from the control unit to the positioning element of the camera to compensate for the parallax between the optical axis of the camera and the light beam or beams emerging from the lamp.

摘要： In order to make continuous lamp operation in a failsafe lamp, particularly a lamp for medical applications, having a discharge lamp possible even when changing over between a power supply system (low voltage supply system of, for example, 24 V) and an additional safety power supply (ZSV), a buffer store is discharged in the event of a fault in the power supply for a supply unit for the lamp by changing over to a standby power source, or, once the fault has been eliminated, from the standby power source back to the normal power supply, the buffer store outputting electrical energy to operate the discharge lamp. The electrical energy supplied to the supply unit (EVG) first passes trough a full-wave rectifier and is then supplied to a voltage converter containing the buffer store. The discharge lamp is subsequently supplied with the electrical energy via a power-regulated inverter. Thus, it is ensured that, even for changeover procedures with different current typesnulle.g. from alternating current to direct currentnullthe power regulation of the discharge lamp permits unimpaired, continuous discharge lamp operation. In the event of a fault in the operation of the discharge lamp or its energy supply, a circuit for operating a halogen incandescent lamp as a reserve lamp is completed.
