<p>A surgical light assembly employs three fixed, coaxially-arranged curved reflectors with a single movable light source mounted for limited movement along the axis of the reflectors to focus the light. The light source and at least the reflective surfaces of two of the reflectors are enclosed so that convective currents over these surfaces are precluded. The light is cooled by a heat sink mounted in heat transfer relation with the light source, with the heat sink having a major surface exposed to atmosphere to dissipate heat. Glare is minimized by precluding direct viewing of the light source from outside the light assembly.</p> |
