Abstract
A method of controlling light beam angles of light beams provided by a light fixture includes obtaining a narrowest and a widest beam angle values of a beam angle of a first light beam provided by a first cluster of LED-optics units and obtaining a narrowest and a widest beam angle values of a beam angle of a second light beam provided by a second cluster of LED-optics units. The method also includes controlling the first and second clusters of LED-optics units such that the beam angles of the first light beam and the second light beam are bound by a smaller one of the narrowest beam angle values of the beam angles of the first light beam and the second light beam and by a smaller one of the widest beam angle values of the beam angles of the first light beam and the second light beam.

A method of controlling light beam angles of light beams provided by a light fixture, the method comprising:
- obtaining, by a controller, a narrowest beam angle value of a range of a beam angle of a first light beam and a widest beam angle value of the range of the beam angle of the first light beam, wherein a first cluster of LED-optics units is designed to provide the first light beam;
- obtaining, by the controller, a narrowest beam angle value of a range of a beam angle of a second light beam and a widest beam angle value of the range of the beam angle of the second light beam, wherein a second cluster of LED-optics units is designed to provide the second light beam;
- and
- controlling, by the controller, the first cluster of LED-optics units and the second cluster of LED-optics units such that the beam angle of the first light beam and the beam angle of the second light beam are bound by a larger one of the narrowest beam angle value of the range of the beam angle of the first light beam and the narrowest beam angle value of the range of the beam angle of the second light beam and by a smaller one of the widest beam angle value of the range of the beam angle of the first light beam and the widest beam angle value of the range of the beam angle of the second light beam.
A light fixture, comprising:
- a first cluster of LED-optics units designed to provide a first light beam;
- a second cluster of LED-optics units designed to provide a second light beam;
- and
- a controller configured to:
- obtain a narrowest beam angle value of a range of a beam angle of the first light beam and a widest beam angle value of the range of the beam angle of the first light beam;
- obtain a narrowest beam angle value of a range of a beam angle of the second light beam and a widest beam angle value of the range of the beam angle of the second light beam;
- and
- control the first cluster of LED-optics units and the second cluster of LED-optics units such that a beam angle of the first light beam and a beam angle of the second light beam are bound by a larger one of a narrowest beam angle value of the range of the beam angle of the first light beam- and a narrowest beam angle value of the range of the beam angle of the second light beam and by a smaller one of a widest beam angle value of the range of the beam angle of the first light beam and a widest beam angle value of the range of the beam angle of the second light beam.
