  • Night vision imaging system (NVIS) compatible lighting with an adjustable melanopic photopic ratio
    Patent number: 12349250
    Abstract: A lighting system and assembly comprising a controller in operable communication with a light unit. The controller is configured to apply a lighting condition using the light unit for a target light color below an upper level of NVIS radiance while controlling a Melanopic-Photopic (M/P) ratio associated with the target light color, and also determine a color mixing for producing NVIS Green A light and NVIS white light for a plurality of levels of NVIS radiance which are less than a maximum NVIS radiance level for a set of M/P ratio values at an upper allowable limit and a set of M/P ratio values at a lower limit.

  • Exterior aircraft light unit and aircraft comprising the exterior aircraft light unit
    Patent number: 9718560
    Abstract: An exterior aircraft light unit for emitting light of a first wavelength and light of a second wavelength, different from the first wavelength is disclosed. The exterior aircraft light unit has an integrated optical structure, which in turn has a first light source configured to emit the light of the first wavelength, a second light source configured to emit the light of the second wavelength, the second light source being positioned adjacent to the first light source, and an optical element for shaping a light emission distribution of the integrated optical structure. The optical element is arranged with respect to the first light source and the second light source in such a way that it affects both the light of the first wavelength and the light of the second wavelength.

  • Products and methods that simulate changes in tooth color
    Patent number: 6461158
    Abstract: A reflective device is provided. The reflective device includes a reflective layer and a first region which reflects light to form an image that simulates a change in tooth color of at least a portion of a viewer's tooth.
