Patent ID: 8491153

Claim:
A method of generating light, comprising: energizing one or more first light emitting elements thereby generating primary illumination of a first wavelength range over a target area, wherein the first wavelength range extends from 560 nm to 610 nm; determining whether a sensor indicates that a light threshold level has been attained utilizing a controller, wherein the light threshold level is indicative of scotopic conditions; if the light threshold level has been attained, then energizing one or more second light emitting elements thereby generating secondary illumination of a second wavelength range toward the target area when the one or more first light emitting elements are energized utilizing the controller, such that 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 the portion of the target area, wherein the second wavelength range extends from either 500 nm to 550 nm or from 610 nm to 660 nm; and wherein the one or more second light emitting elements are aimed in a different direction than the one or more first light emitting elements toward the target area to provide radiation patterns having an intensity shift from one area of the target area to another area of the target area in response to the light threshold level having been attained.
