Abstract: A light ring assembly for a smart-home device may include a plurality of light-emitting diodes (LEDs) and a light guide, where the light guide may include a plurality of cutouts that receive the plurality of LEDs, and a plurality of transmissive sections between the plurality of cutouts where a thickness of the transmissive sections tapers as the transmissive sections extend away from the plurality of cutouts. The light ring assembly may also include an output surface that receives light emitted from the plurality of LEDs through the plurality of transmissive sections, where the output surface is substantially circular.
