Abstract

An electro-optical device (100) capable for providing a photobiomodulation effect in a user of the device (100), having at least one electro-optical element (EL1) arranged to emit electromagnetic radiation having a peak emission wavelength between 700-1400 nm, a control circuit (120, 130), and a driver circuit (110). The control circuit (120, 130) has a timer (135) configured to determine an on-period for the electromagnetic radiation emitted by the electro-optical element (EL1), and/or has a dose calculation unit configured to determine an accumulated dose of the electromagnetic radiation at the user. The control circuit (120, 130) is configured to instruct the driver circuit (110) to shut off the electro-optical element (EL1), if a predetermined maximum on-period is exceeded, and/or if a predetermined dose of the electromagnetic radiation at the user is exceeded.
