摘要： A hand-held surgical light assembly is provided with a light source, and a handpiece which is adapted to be grasped and manipulated by a user. The handpiece has a light guide with a proximal end optically connected to the light source, and a distal end which projects outwardly from said handpiece so as to direct light guided thereby onto a field of view determined by manipulation of the handpiece by the user. The handpiece includes a switch assembly which is operatively coupled to the light source to allow user selection between at least two different light intensities (e.g., essentially on/off) discharged by said light guide onto the field of view. In preferred forms, the switch assembly includes an electrically conductive inner core and an electrically conductive outer tubular elastomeric member concentrically positioned in surrounding, but spaced relationship, with the inner base. When contact between the inner base and the outer elastomeric member is made, switch circuitry changes the visible light intensity of the visible light generated by the light source, e.g., by either directly modulating the current to the lamp itself, or by providing an electrically operable shutter assembly which masks the light generated by the light source. The former embodiment is especially well suited for surgical lights which are self-contained (i.e., have the light sources contained in the handpiece), while the latter is especially well suited for surgical lights which have remotely positioned light sources.
