Embodiment Construction
[0054] According to one aspect, the specification relates to a lighting system for generating an output light beam representing natural light of an object.
[0055] In the art the expression "natural light" is understood as light having spectral characteristics similar to the light from the sun reaching the earth. This light has a natural spectral curve, defined as a function of light intensity as a function of wavelength. As is known to those skilled in the art, the spectral profile of light from the sun can vary depending on several factors, such as time of day, time of year or geographic location.
[0056] Several standards are known in the art to provide spectral references for natural light. For example, the International Commission on Illumination (hereinafter referred to as "CIE") has established a well-defined "D" series of daylighting standards representing natural light under different conditions. A well-known standard is CIE Illumination D65, which stands for the ...
