The basic idea of ​​the invention is to divide the color of the light based on the color dominant wavelength. After dividing the color into different groups, a specific group of colors may be selected based on predetermined criteria. One of the criteria is, individuals is to perceived as higher than the actual temperature of the ambient temperature, the other criteria, individuals may be to perceived as lower than the actual temperature of the ambient temperature. Thereafter, the control signals, control signals for controlling the dominant wavelength of light emitted from the at least one light source by the selected color group is created. Finally, control signals, said generated is transmitted to the light source, thereby controlling the effect on the temperature regulation of the exposed individuals of the light source based on said predetermined reference. The present invention, color illumination is applied to change the perception of the ambient temperature of the person, in that it can save energy for heating and air conditioning systems, it is advantageous. The use of the illumination control device for varying the color of light results in providing a flexible solution. The apparatus because, since it is possible to easily change the environment to perceive the actual cold warmer or more than room temperature.
