Claim:
An operating room light fixture comprising: a light fixture housing having a light emitting side and an axial light emitting direction; a first lighting unit supported by said light fixture housing and having a radially centrally located first light source and a first lighting unit reflector radially outward of said first light source and directing emitted light axially outwardly for generating an even surface light; a second lighting unit supported by said light fixture housing, said second lighting unit being arranged axially after said first lighting unit in the axial light emitting direction in which the light emerges, said second lighting unit having a second light source substantially coaxial with said first light source disposed in an axial path between said first light source and said light emitting side and a second lighting unit reflector radially outward of said second light source and radially inward of said first lighting unit reflector and directing emitted light axially outwardly for generating an additional in-depth concentrated illumination; a control element having a single control actuation range; and a control unit for controlling a luminous intensity of said first light source and said second light source based on a state of said control element with respect to said single control actuation range to provide a preset luminous intensity control curve corresponding to said control actuation range.
