Abstract
A device for supplying luminous energy to a dental instrument to illuminate the area of treatment on a tooth being treated. The luminous energy is applied from a bulb housed in the device through an optical fiber extending through the dental instrument and having an end disposed for receiving the luminous energy from the bulb. Provision is made for energizing the bulb when the device is mounted on an electrical supply cable. A contact arrangement of two conductive studs disposed in a bore of an insulating sleeve and axially biased by a conductive spring to extend from the bore provides for making contact between the bulb and supply cable when the device is mounted on the supply cable. A section of the bore of the sleeve between the ends of the sleeve defines shoulders limiting the axial travel of the studs which have enlarged ends for engaging the shoulders.
