摘要： A luminaire body for a surgical operation light with an annular reflector has at least two electric light bulbs, a first bulb of which with its socket is associated in normal operation with a given centered position (with respect to the reflector) in the stationary part of the luminaire body, while a second bulb with its socket is situated in a reserve position away from the centered position; in case of a failure of the first bulb the positions of the sockets of both bulbs are changed by an electromagnetically operated turning service such that the second bulb can be turned to the original centered position of the first bulb for reserve-bulb operation after the first bulb has been withdrawn from the centered position. The first bulb is configured as a double-end gas discharge bulb with terminal contacts situated axially opposite one another, which is held and contacted together with the second bulb in the form of an incandescent bulb which, together with the second socket disposed at a distance, is configured as part of the turning system rotatable about an axis for holding and contacting the other end of the gas discharge bulb. In the event of failure of the first bulb the desired change in the positions of the bulbs is brought about by a releasing action and with the aid of a biased torsion spring.
