Medical lamp with multi-component projector unit |
摘要 |
A medical lamp having a reflector in the shape of an ellipsoid of rotation containing on its interior side a plurality of facets which provide for a largely shadow-free illumination of the area to be lit. An opening is provided in the reflector, which is surrounded by a ring flange. A lamp having a spiral-wound filament therein is inserted into the ring flange so that its bulb is oriented towards the surface of the reflector where the light exits, whereby the spiral-wound filament in the bulb is positioned along the reflector axis. The bulb has a base with a cylindrical portion which is adjacent to a plate flange. The cylindrical portion of the base is encircled by the ring flange of the reflector opening in such a manner that the bulb is secured against shifting in the radial direction of the reflector axis. A clip attached to opposite ends of the reflector contacts the plate flange located at the rear end of the lamp in a locking manner to secure the base to the outer edge of the ring flange and, as a result, the lamp is set in its correct spiral-wound filament position. A major advantage of the present invention is its simple construction and the speed with which the lamp can be changed.
