An illumination apparatus is disclosed, comprising: a first light source having a first spectral light distribution with a first light intensity peak about a first peak wavelength, and a second light source having a second spectral light distribution with a second light intensity peak about a second peak wavelength being different from the first peak wavelength, a third light source having a third spectral light distribution with a main light intensity peak about a third peak wavelength being different from the first peak wavelength and from the second peak wavelength, wherein the illumination apparatus is configured to provide adjustment of light intensity of the first light source and of light of the second light source, wherein the illumination apparatus provides an adjustment of light intensity of the third light source to compensate for the adjusting of the relative light intensity between the first light source and the second light source.

Illumination apparatus

The present invention relates to a light control system. The light control system comprising: a plurality of light sources each configured to emit light within a predetermined spectral range, each of the plurality of light sources being configured to illuminate a corresponding sub-portion of a space, a sensor configured to within the space, detect a location of a human or an animal; and a control engine configured to control the plurality of light sources based on the detected location of the human or the animal such that a sub-portion of the space in which the human or the animal is not present is exposed to the light within the predetermined spectral range at a predetermined threshold intensity. A method for exposing a sub-portion of a space with light within a predetermined spectral range at a predetermined threshold intensity is also provided.
