A chassis for a light source for medical/surgical applications comprises a lamp assembly having a support plate slidable through a housing door into chassis mounted rails or slides and having fixed thereon lamp heat sinks having the form of mounting plates with heat dispersing fins projecting therefrom. The supporting plate further includes or supports plugs which mate with corresponding plugs in the rear as the plate is inserted on the rails and pushed back onto stops, providing secure, aligned positioning. The heat sinks that hold the lamp in position are slotted so as to resiliently secure and electrically contact the lamp under the action of first and second resilient clamps which position the lamp in predetermined alignment and allow for thermal expansion, for example, of the sapphire window. Light from the lamp is projected along a path through heat filters to an output turret assembly which allows for selection of different fiber optic cables connected to plural connectors on the turret. An attenuator in the beam path cooperative with manual and automatic controls allows adjustment of the light intensity manually or from an automated source such as a video camera seeing a field of view illuminated by light provided from the source through a connected fiber optics system. A printed circuit board is located in a part of the system partially separated by an air baffle. First and second fans apply cooling air from one rear panel portion across the optics and around the baffle over the power supply circuit board and out through louvers in an opposite rear panel portion.
