The invention relates to a class of radiating electron-optical devices which can be used for the beneficial effects of light radiation of the visible spectrum (and close thereto band) on living organisms and biological entities - human, animals, plants, to the products, materials and objects biological origin - for food products, raw materials for the food industry, agricultural seed material, microorganism strains and so forth. The use of utility model is aimed at the return of living organisms and biological objects to a stable life state of the best options after periods of serious negative states (states of illness, depression, depression and so on.), In the case of man this goal - the removal of local muscle spasms, a common disposal of excessive nerve and muscle tension, the effects of stress, chronic fatigue and so on. In this device, the location of the blue light-emitting diodes, green, and red light emission spectra of such organized time: a light emission spectrum of the LEDs are distributed on the working surface of the device - he mounting plate - symmetrically and uniformly periodic, having a period between a certain area. And these gaps are placed LEDs other light emission spectra. Those. location in the area of the circuit board LEDs of different spectrum periodically organized on the principle of close to a checkerboard pattern. During time intervals and interleaving the glow mode 3 different light emitting groups - blue, green and red - organized in frequency mode continuously and sequentially successive outbreaks of different groups of LEDs is in the above sequence. In this phase the active light emitting LEDs of one group coincides with the termination of the phases of the radiation of the other two groups of the LEDs and the duration of such periods can vary - controlled via the device control block. And this alternation is strictly measured periods of time in a clear sequence object light influence exposed to the light of only one of the radi
