PROBLEM TO BE SOLVED: To allow simple repositioning of an illumination field.SOLUTION: An illumination apparatus comprises at least one light transmitter 12, an optical transmission system 14, an optical system holder 24 for the optical transmission system 14, and a setting device 28. The optical system holder 24 can be moved by the setting device 28, and thereby an illuminated region can be focused at a working distance. In this connection, the optical system holder 24 is fixed at, at least, one fixation point 26 so that the optical system holder 24 is moved relative to the light transmitter 12 in a compulsory guided manner on actuation of the setting device 28, however, maintains its relative position with respect to the light transmitter 12 at the fixation point 26. |
