Abstract
Proposed is a light module () comprising at least two primary light sources () capable of emitting a primary color light. This allows the light module to emit light having intensity (Y) and color coordinates (x,y) through additive color mixing of the constituent primary colors. The light module further comprises an modulator () capable of modulating the primary light sources enabling embedment of data in the light emitted. The modulator () is arranged to modulate the color coordinates of the light emitted for embedding the data. This is especially advantageous as the sensitivity of the human eye to changes in color is lower than to changes in intensity. The invention thus advantageously allows embedding the data into the light emitted from the light modules () of an illumination system () without reducing the performance of its primary function as an aid to human vision.
