Abstract

In this work we describe why we can use colour sensors for a colour feedback control in LED-luminaires. We describe the state of the art sensors for that purpose and why we need to take ageing effects of colour sensors in account. We show how the sensors are characterized and how our approach for dor colour sensor ageing will look like. First characterisation results of a thermal behaviour of a colour sensor is evaluated and discussed.

Farbsensor basierte Farbortregelung in Multikanal LED-Leuchten setzen voraus, dass die spektralen Empfindlichkeiten sowohl der emittierten Strahlung der LED-Leuchte sowie der Tristimuluswerte des Menschen genugen. Hierzu werden die Schwierigkeiten untersucht, welche aufgrund von Alterungserscheinungen der Farbsensoren bei der Farbortbestimmung und der damit zusammenhängenden Farbortregelung entstehen.German
