Abstract
A light-emitting diode (LED) luminaire comprising two sets of LEDs, a phase-amplitude circuit, and an LED driving circuit is used to replace a conventional luminaire with a possible severe temporal light artifact. The phase-amplitude circuit is configured to produce two sets of modulating signals with a predetermined phase retardation between the two. The LED driving circuit is configured to produce two sets of LED driving current in response to the two sets of modulating signals and to drive the two sets of LEDs, resulting in imperceptible visual stimuli at temporal modulation frequencies as a result of possible frequency pre-mix. On the other hand, the imperceptible visual stimuli in another embodiment may cause human brain to perceive modulated lighting stimuli and to demodulate thereof into a benign stimulus in the brain without an apparent flicker, thereby endogenously entraining a gamma oscillation, and drastically reducing eyestrain and visual discomfort.
