Colour consistency refers to the average amount of variation in chromacity among a batch of light sources. In human terms it refers to the amount of perceived variation in colour in lighting of any variety.
Lighting applications today demand consistency of colour, and the larger and more complex the installation, the more critical the issue of colour consistency becomes.
Binning is a post-manufacturing testing and sorting process that makes it possible for manufacturers to select LEDs (or more accurately, groups or bins of LEDs) that conform to stated specifications – minimizing variation at the LED level and resulting in higher consistency.
However, when two or more channels are mixed together – or when multiple channels are used to create white light (e.g., RGB, RGBW, RGBA) the consistency of the luminaire output can still vary as much as 10 – 15 MacAdam ellipses, resulting in noticeable colour shifts. This variation points to the need for a new, even more stringent approach to consistency – one designed to meet the needs of increasingly sophisticated dynamic colour lighting applications.
Chromasync is an advanced algorithm from Philips Color Kinetics that delivers improved colour consistency from luminaire to luminaire by adjusting the node’s colour point. With Chromasync enabled, colours are more consistent, regardless of the specific LEDs used, date of manufacture, and other manufacturing variables.
