Efficient Halogen Lamp Daylight Simulator for Color Vision Examination

Recently there has been a growing interest in the selection of product colors for design engineering purposes and for quality control. The selection is generally based on color samples and the quality control is carried out with specific measurement instruments. In low quantity production it is common to avoid instrumental color measurement using human control personnel instead. For such subjective color judgment it is necessary to have standardized illumination that is usually produced by high cost daylight simulator lamps. Our aim was to build a cost effective daylight simulator with halogen incandescent light sources that can match the parameters (CCT, CRI, MIvis and Illumination) of the similar but more expensive products.
