Project Details

Description

Flicker, more correctly temporal light modulation (TLM), has once again become a problem with the introduction of LED-based lighting technology. TLM has a negative effect on human health in the form of irritation, headaches, eyestrain and migraine.
This study aims to investigate neurological effects of TLM on the brain, such as visual stress and headache. This by exposing research subjects to different frequencies and waveforms of TLM at the same time as the brain is examined in an MRI camera
(Magnetic Resonance Imaging) with fMRI (functional MRI) technology. Currently, there are only limit values for the visual flicker, no limit for neurological impact. The negative consequences of TLM today constitute an obstacle to wide and rapid adaptation of the new kind of LED lighting technology, and a threat to the health and well-being of a significant subgroup of sensitive individuals, and thereby an obstacle to potential energy saving.
