Abstract (en)
[origin: WO2008061767A1] The present invention relates to an operation or examination lighting unit with at least one first and at least one second light source which have a common optical system, and a control unit which can control the brightness of the first light source separately from the brightness of the second light source, and which by means of variable control of the brightness of the first and of the second light source causes a change of geometry, in particular a displacement and/or variable focusing of the total light field produced by the operation or examination lighting unit.
