Abstract
A lighting fixture comprising a light source, an exit lens and an XY beam manipulating system is disclosed. The XY beam manipulating system is arranged along an optical axis of the lighting fixture between the light source and an outer surface of the exit lens. The XY beam manipulating system is configured to perform movements within a plane and with two degrees of freedom, thereby causing an exiting light beam of the lighting fixture to move in accordance with a selected movement pattern.
Claims15
A lighting fixture comprising:
- a light source;
- an exit lens;
- and
- an XY beam manipulating system, the XY beam manipulating system being arranged along an optical axis of the lighting fixture between the light source and an outer surface of the exit lens,
- wherein the XY beam manipulating system is configured to perform movements within a plane and with two degrees of freedom, thereby causing an exiting light beam of the lighting fixture to move in accordance with a selected movement pattern.
A method for controlling a lighting fixture comprising a light source, an exit lens, and an XY beam manipulating system, the method comprising the steps of:
- selecting a desired movement pattern for a light beam exiting the exit lens,
- obtaining at least one transfer function between the selected desired movement pattern and input parameters for the XY beam manipulating system,
- generating input parameters for the XY beam manipulating system, based on the at least one transfer function, and
- operating the XY beam manipulating system in accordance with the generated input parameters.
