  • Patent number: 11262048
    Abstract: An illumination system can produce a dynamically variable illumination pattern. The illumination system can include a light guide. The illumination system can include projection optics, which can contribute to the illumination pattern at relatively low beam angles (i.e., beam angles formed with respect to a surface normal of the light guide). The projection optics can include individually addressable light-producing elements that can direct light through one or more focusing elements. A controller can control which of the light-producing elements are electrically powered and can therefore control the illumination pattern contribution from the projection optics. The illumination system can also include scattering optics, which can contribute to the illumination pattern at relatively high beam angles. The scattering optics can direct light out of the light guide over a relatively large surface area, which can help reduce glare when the light guide is viewed directly.
