Method and apparatus for setting a chromaticity coordinate
First Claim
1. A method for setting a color locus of a luminaire comprising at least one phosphor-converted light-emitting diode and at least one monochromatic light-emitting diode, wherein the method comprises the steps of:
- setting a current for the at least one phosphor-converted light-emitting diode;
setting a pulse width modulation for the at least one phosphor-converted light-emitting diode; and
setting a current or a pulse width modulation for the at least one monochromatic light-emitting diode.

Abstract
A method for setting a color locus of a luminaire (110) comprising at least one phosphor-converted light-emitting diode (103, 105) and at least one monochromatic light-emitting diode (104), wherein the method comprises the steps of: setting a current for the at least one phosphor-converted light-emitting diode (103, 105) setting a pulse width modulation for the at least one phosphor-converted light-emitting diode (104); and setting a current or a pulse width modulation for the at least one monochromatic light-emitting diode (104).

14. An apparatus for setting a color locus of a lamp or luminaire comprising:
-
at least one phosphor-converted light-emitting diode; at least one monochromatic light-emitting diode; a control unit, which detects a brightness and/or a temperature of the light-emitting diodes via at least one sensor and drives a driver in such a way that; a current can be set for the at least one phosphor-converted light-emitting diode; a pulse width modulation can be set for the at least one phosphor-converted light-emitting diode; and a current or a pulse width modulation can be set for the at least one monochromatic light-emitting diode. - View Dependent Claims (15, 16, 17, 18, 19)
