Abstract
In the paper we represent experimental results of the research of human vision sensitivity to pulsed radiation of discrete light emitting diodes (LEDs) of different colors when their dissipated electrical power was the same. We used color components of RGB LED matrix and determined the values of the dissipated power at which resultant LED radiation was perceived as white light. These power values were used to investigate sensitivity of human eye to radiation of each color of RGB matrix. Spectral characteristic of RGB LED under investigation was checked for presence of additional spectral components. The results we obtained give the possibility to develop information systems with concealment of the data transfer process using white light which color components are informative.
