  • Enhanced lighting
    Patent number: 11906153
    Abstract: Apparatus and methods for enhanced lighting. The apparatus may include a light-transmitting body. The apparatus may include a light projector. The projector may be configured to propagate into the light-transmitting body an incoming incoherent light. The projector may be configured to propagate into the light-transmitting body an incoming visible coherent light. Emerging coherent light within a visible wavelength rage attributable to the incoming visible coherent light may have a first intensity. The first intensity may be greater than a second intensity. The second intensity may be an intensity of any emerging coherent light that is within the wavelength range and is attributable to the incoming incoherent light. Emerging light may be light that emerges from the light-transmitting body.
