Estimation and First Ageing Results of Colour Sensors for a Feedback Control in Multichannel LED-Luminaires

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
