Stress-reducing lighting

Abstract

Apparatus, systems, and methods are provided for stress reduction and/or other beneficial health effects in a human by controlling one or more properties of lighting observed by the human, such as color (or wavelength) and/or intensity. Area lighting (e.g., for a room, a portion of a room, a vehicle) and/or specific equipment (e.g., medical equipment and devices) may incorporate an apparatus or system provided herein. During operation, a lighting fixture or other source outputs lights in selected regions of the visible light spectrum, such as an amber region (e.g., 570-680 nm), a red region (e.g., beyond 680 nm), and a green region (e.g., 510-540 nm), while eschewing other regions (e.g., below 510 nm). Light emitted from a system or apparatus may account for some, most, or all radiant flux encountered by the human, and the stress-reduction benefit may be verified via biological or biometric examination.
