LIGHT THERAPY DEVICE Russian patent published in 2015 - IPC A61N5/06 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. A light therapy device contains at least one light source; a control device for the control of the light source work; boundary memory, containing information about boundaries, determining the boundaries for the distance (D) and relative angle (φ) of the user's head relative to the light source; a tracking tool for tracking the factual distance and factual relative angle of the user's head and formation of an output signal, showing the measured distance and angle. The control device has an inlet, connected with the memory, for the reception of information about the boundaries and has an inlet, connected with the tracking tool, for the reception of the outlet signal from the tracking tool. The control device compares the output signal from the tracking tool with information about the boundaries and produces a warming signal, when the factual position and/or orientation of the user's head and/or eyes is/are beyond the said boundaries.

EFFECT: construction improvement.
