FIELD: medicine.
SUBSTANCE: device includes control unit, radiation unit encasing printed circuit with sequential intermittent rows of emission sources with LEDs of blue, red and green emission ranges, including parallel connected element branches with LEDs connected in sequence, and power unit. Control unit includes microcontroller with outputs connected to keyboard, display, digital to analog converters and impulse current stabilisers. Output of each converter is connected to stabiliser input, output of which is connected to emission source with a branch including padding resistor connected in sequence with LEDs. Each row of emission unit includes different LED number, and each emission source carries two or three intermittent LEDs with red, green or blue emission ranges.
EFFECT: simplified control of light-beam therapy device with different emission ranges.
