  • Patent number: 10939522
    Abstract: Systems and methods include receiving a desired light color temperature-time function. A first drive signal parameter is selected for a first light source having a first color temperature and a second drive signal parameter is selected for a second light source having a second color temperature. The drive signal parameters are selected to create a color temperature for a value of the desired light color temperature-time function. First light is emitted from the first light source and second light from the second light source. The first light and the second light combine to form blended light at the color temperature for the value from the desired light color temperature-time function.
