Abstract
Abstract A video system having a video processor mounted to a frame, a viewing probe coupled to the video processor that has an imaging device at its distal end, and an illumination apparatus coupled to the viewing probe. The illumination apparatus includes a lamp assembly containing a light source. The lamp assembly also contains first and second heat sink members thermally coupled to the light source. Each of the heat sink members are electrically conducting and electrically insulated from the other. The first and second heat sink members are electrically coupled to the electrodes respectively of the light source. The illumination apparatus further includes a housing containing an opening configured and dimensioned to permit the insertion of the lamp assembly therein. The illumination apparatus further includes a receptacle disposed within and supported by the housing and having first and second electrical conductors. The illumination apparatus further includes resilient clips, connected to the first and the second heat sink members to the first and second conductors of the receptacle respectively, upon insertion of the lamp assembly into the housing. Therefore, the light source can be actuated upon application of a power supply to the first and second electrical conductors of the receptacle.
