Colour match method of primary colour selection in colour mixing LED luminaires

摘要

A method whereby the chromaticity of primary colours used for additive colour mixing in an LED based luminaire can be defined and selected electronically. A technique is described whereby the user of the luminaire is able to select and store within the luminaire the exact chromaticity produced in relation to any of the primary colours that are typically used by the luminaire when generating coloured light by additive mixing of the primary colours. By allowing the user of the luminaire control over the exact colour coordinates of the primaries used for colour mixing, it is possible to precisely match the colour output of the luminaire to that of other manufacturers or products based on different colour mixing and light source technologies.
