Abstract:
A luminaire body for a medical light comprising at least two bulbs, a first bulb of which, in normal operation with its socket, is associated with a given centered position in the stationary part of the luminaire body, and a second bulb with its socket is in a reserve position away horn the centered position, and in ease of failure of the first bulb the positions of the sockets of both bulbs can be changed by an electromagnetically operated turning device so that the second bulb can be turned to the centered position for reserve bulb operation after the first bulb is withdrawn from the centered position, wherein first bulb is configured as a gas discharge bulb with terminal contacts axially opposite one another, which is held and contacted at one end in a first socket together with a second bulb configured as an incandescent bulb, which together with a second socket arranged at a distance for holding and contacting the other end of the gas discharge bulb, is configured as part of a turning device rotatable about an axis, while by a releasing procedure a rotation of the turning device can be produced by means of a torsion spring biased between the turning device and a fixed part of the luminaire body.
