Method and apparatus for setting a chromaticity coordinate
摘要:
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).
