A light ring assembly that is designed to provide bright, uniform and homogenized illumination and that can be used with any number of vehicle and non-vehicle lighting applications. According to one embodiment, the light ring assembly includes a housing, a circuit board with a number of individual light sources, a light ring and a lens. Light emitted by the light sources enters an optical input surface on a bottom side of the light ring, is reflected within the body of the light ring so as to mix and become more distributed, and then exits an optical output surface on a top side of the light ring.

A light emitting device is provided comprising: a body; a base portion configured for mounting the light emitting device to a reflector of a headlight or taillight, the base portion being arranged at a first end portion of the body; at least one light-emitting diode arranged at or inside of the body; at least one infrared light source provided at the body and configured to emit infrared light; and a thermal barrier arranged in between the at least one infrared light source and the at least one LED and configured to block at least part of radiation emitted from the at least one infrared light source towards the at least one LED.

An electronic device such as a voice-controlled speaker device may have a housing. A speaker and other input-output components and control circuitry may be mounted within the housing. A set of controlled light-emitting components may emit light that passes through an upper housing wall or other housing structure. Light from the light-emitting components may be spread laterally by multiple light diffusing layers such as a lens diffuser layer having lenses overlapping respective light-emitting components, a textured diffuser layer formed from textured coatings on a substrate, and a volume diffuser layer having light-scattering structures in a polymer layer. The lens layer may be formed from a transparent member with integral lenses having curved inner surfaces and opposing curved outer surfaces and central depressions. A light-guiding portion of the transparent member may guide light to a circular peripheral edge to form an illuminated ring visible through the upper housing wall.

A vehicular lighting device includes a scanning light source that includes a semiconductor light source and a motor, and scans a region in front of the lighting device, with light emitted from the semiconductor light source, in accordance with motion of the motor, and a lighting circuit that changes the light quantity of the semiconductor light source in synchronization with the motion of the motor, during a normal lighting period, so as to obtain a predetermined light distribution pattern. The lighting circuit starts the motion of the motor, in response to a lighting command for headlight flashing during a stop period of the motor, and continuously lights the semiconductor light source asynchronously with the motion of the motor, during a start-up period that precedes the normal lighting period.
