The article deals with the main circuitry and software aspects of the creation a LED dynamically controlled system of high-quality lighting with the broad range of color temperatures Tc = 1700 – 10,000 K as a part of experimental installation of the hardware-software complex for impact on a person’s functional status. The findings of investigation on impacts of lighting with a different color temperature on a human body are given. These studies were based on changes in indicators of electrical activity of the brain, heart work, arterial blood pressure and other parameters. Processing of measurement data revealed efficiency and a nature of influence of light with different color temperatures on psychophysiological and functional status.
