Embodiment Construction

[0121] figure 1 A flow chart is shown of a method 100 according to the invention for controlling a lighting fixture with a subtractive color mixing system for emitting light with a target color, the method comprising:

[0122] - receiving (102) target information indicating (such as defining) said target color,

[0123] - calculating (104) a target control set point for each of the plurality of color subtractive filters based on:

[0124] - the target information, and

[0125] - calibration data, said calibration data for the sets of control set points being indicative of luminescent colour,

[0126] - controlling 106 each of said color subtractive filters according to each calculated target control setpoint for each of said color subtractive filters.

[0127] figure 2A structural diagram of a lighting device 200 is shown (wherein "lighting device" and "lighting fixture" may be understood interchangeably throughout this application). The lighting device comprises a cooli...

Abstract

A method for controlling a lighting fixture having a subtractive color mixing system for emitting light having a target color. The method includes receiving target information indicative of, for example, defining the target color, calculating a target control setpoint for each of the plurality of subtractive color filters based on the target information and calibration data, the calibration data for a plurality of sets of calibration control setpoints indicative of a luminescence color, and controlling each of the subtractive color filters according to each of the calculated target control setpoints for each of the subtractive color filters.

Description

technical field [0001] The present invention relates to a method for controlling a lighting fixture, and more particularly to a method for controlling a subtractive color mixing system of a lighting fixture based on calibration data, but also to a corresponding control device, a lighting fixture system and its use. Background technique [0002] Lighting fixtures may be used to create various light effects and / or mood lighting in connection with, for example, concerts, live performances, television shows, sporting events, or as architecturally installed lighting fixtures to produce various effects. [0003] Lighting fixtures can be expensive, can be imprecise in emitted colors, and can be inconsistent, such as differences in properties (such as one or more emitted colors) between different lighting fixtures. [0004] Accordingly, an improved method for controlling a lighting fixture, and more particularly, a method for controlling a subtractive color mixing system of a light...
