Abstract: A basic idea of the invention is to categorize color of light into groups on the basis of dominant wavelength. After the colors have been categorized into different groups, a particular group of colors may be selected on the basis of a predetermined criterion, one criterion being that an individual is to perceive the ambient temperature as higher than it actually is, while another criterion may be that the individual is to perceive the ambient temperature as lower than it actually is. Thereafter, a control signal is generated for controlling the dominant wavelength of light emitted from at least one light source in accordance with the selected group of colors. Finally, the generated control signal is transmitted to the light source(s) to be controlled, for emitting light of the selected group of colors, thereby influencing the thermoregulation of an individual being exposed to the light of the selected group of colors on the basis of the predetermined criterion.

Abstract: A basic idea of the invention is to use different properties of light (101), such as e.g. intensity and color temperature, to influence physiological thermoregulating parameters of a vertebrate (102), for example a human being, being exposed to the light. At least one particular physiological thermoregulating parameter (e.g. skin temperature) of an individual is being measured and supplied to a controller (103) for comparison with a desired target value of the measured parameter. The property of light can then be adjusted to regulate the actual value of the thermoregulating parameter of the individual being exposed to the light. Thus, a dynamic device (100) for influencing the thermoregulation of an individual by using different properties of light is provided.
