Lighting equipment with optimal stimulation of non-visual functions

摘要

The lighting equipment comprises a lighting device with a plurality of light sources for delivering white light having a tunable light spectrum, and a monitoring and control device that controls the light sources in a modulation cycle for modulating the light spectrum, which cycle comprises a first period where the light spectrum is red-enriched, a second period where the light spectrum is gradually modulated from red to blue, a third period where the light spectrum is blue-enriched, and a fourth period where the light spectrum is modulated gradually from blue to red. The control device is arranged to detect reception of a signal indicating a human presence, and, in response, reinitializes the modulation cycle when the modulation cycle is in the first period, or gradually modulates the light spectrum from blue to red when the modulation cycle is in the second, third or fourth period before reinitializing the modulation cycle.
