The invention relates to medical engineering, in particular to devices for phototherapy. The device consists of a plastic body with a securing strap on the wrist with integral protruding 12th LEDs on the back side, based on 2 types of spectrum, but with different wavelengths to increase light penetration into the living human tissue and enhancing the therapeutic effect in the prevention and for medicinal purposes. Obverse is a conventional clock dial with one hand, which are located under the four batteries, a control unit and software. With the device arranged laterally 6 buttons and LED trigger timer and one wheel set the timer. Estimated device has the following advantages for the prevention and treatment of SARS and skin diseases: the possibility of using a single-spectrum light with different wavelengths or simultaneous use of multiple spectra for enhancing the therapeutic effect. The device is easy to use, has the size and shape of common household wristwatch that allows during procedures to operate. The device is easy to assemble, cheap to use and well sterilized. Selected batteries provide operation for 50 hours of continuous operation (with a procedure in 30-40 min. In a patient) and can be easily replaced.
