Sustainable outdoor lighting system

摘要

A method of generating light involves energizing one or more first light emitting elements (120) thereby generating primary illumination of a first wavelength range over a target area (220), and energizing one or more second light emitting elements thereby generating secondary illumination of a second wavelength range toward the target area during a critical period. Both the primary illumination and the secondary illumination are combined within at least a portion of the target area thereby enhancing at least one visual property within the at least a portion of the target area.
