Abstract

A method for generating and selecting the colour produced by a colour mixing luminaire involves implementing functionality within the luminaire that automatically generates suitable colour transitions that can be controlled remotely using industry standard control protocols such as DMX or locally using the luminaire's user interface. The colours output by the luminaire may be calibrated with reference to a colour space system, such as by using standard CIE 1931 xyY chromaticity coordinates. The method is particularly suited to lighting fixtures that utilise the wavelength mixing of a plurality of different coloured light emitting diodes (LEDs) to generate a desired colour. The invention solves an inherent problem of unwanted intermediate colour output in such colour mixing luminaires that users encounter when changing from one colour to another or selecting different colours from an in-built colour palette.
