US 2018/0021593 A1 · Temporally Modulated Multi-LED for Enhanced Subconscious Physiological Responses

Abstract

A light source and a method of generating a light using the light source is disclosed. The light source is configured to produce a plurality of distinct colors in generating the light, one of the distinct colors falling within a blue spectral light band. A light controller modulates the spectral light produced by the plurality of distinct colors. The modulation provides melanopsin contrast in order to increase melanopsin responsiveness of a subject exposed to the generated light and maintains the color temperature, color quality, and color constancy experienced by the subject in a lit viewing environment within an acceptable range.

Dependent claims

A method of generating light using a light source, the method comprising:

generating lighting signals for controlling the light source, wherein the light source is configured to produce a plurality of distinct colors in generating the light, at least one of the distinct colors falling within a blue spectral light band;
modulating the lighting signals to modulate the light produced by the plurality of distinct colors, the modulation being chosen to provide optimal melanopsin contrast in order to increase melanopsin responsiveness of a subject exposed to the light and the modulation being chosen to maintain color temperature and color quality within an acceptable range;
and
applying the modulated lighting signals to the light source and generating the light for thereby increasing the melanopsin contrast responsiveness of the subject exposed to the light.

A method of adapting a pulsed light for general illumination, the method comprising:

providing a plurality of LED channels each generating light, the LED channels including at least four distinctly colored LEDs;
setting a first light mode at a first spectrum to maximally stimulate melanopsin responsiveness of a subject, the first spectrum being formed by light from the at least four distinctly colored LEDs, the first light mode having a light intensity that maximizes melanopsin contrast responsiveness and having a blue light intensity, a red light intensity, and/or a green light intensity that define a color temperature and brightness of the first light mode;
setting a second light mode at a second spectrum to more weakly stimulate melanopsin responsiveness of the subject compared to the first light mode, the second spectrum being formed by light from the at least four distinctly colored LEDs, the second light mode having a light intensity that more weakly stimulates melanopsin responsiveness and having a blue light intensity, red light intensity, and/or a green light intensity that define a color temperature and brightness of the second light mode;
setting the color temperature and brightness of the first light mode to match the color temperature and brightness of the second light mode;
and
modulating between the first light mode and the second light mode to stimulate the subject while maintaining an optimized melanopsin contrast between the first light mode and the second light mode.
