Abstract:
Various arrangements for light distribution incorporated as part of a device are presented. A circular light guide may be used that receives light from a plurality of light emitters that can be arranged in a circular pattern. A conical reflector may be used and may be positioned to reflect light emitted from the circular light guide onto an exterior of a case of the device. The conical reflector may reflect light such that light is reflected by the exterior of the case in the shape of a halo into an ambient environment of the device.
