Accommodative integrated control of the daylight illuminant and electric light using two or more sensors for the controlled optical distribution

Japanese Patent JP6038120

B2

A system and a method for controlling light distribution in a space including multiple installed light sources (111, 112, 221-223) and an external light source (103, 203). The method includes measuring the luminance levels of light from the multiple installed light sources (111, 112, 221-223) and the external light source (103, 203) at a plurality of measuring areas within the space, controlling the intensity level of each of the installed light sources (111, 112, 221-223) and the amount of light from the external light source entering the space (103, 203) based on the measured luminance levels, and tuning the intensity level of each of the installed light sources (111, 112, 221-223) and the amount of external light entering the space (103, 203) to optimize the conditions such that the mean-squared error between the measured luminance levels and pre-defined target luminance levels for the respective plurality of measuring areas is minimized, and the amount of energy consumed by the multiple installed light sources (111, 112, 221-223) is minimized.
