An electronic device includes an electromagnetic radiation source having an axis, a set of optics disposed about the axis, a reflector disposed about the axis non-symmetrically, and a controller configured to operate the electromagnetic radiation source while controlling a beam steering orientation (e.g., rotation) of the reflector. The reflector is disposed to reflect electromagnetic radiation emitted by the electromagnetic radiation source. The set of optics is disposed to shape electromagnetic radiation emitted by the electromagnetic radiation source and direct electromagnetic radiation received from the reflector into a panoramic field of view about the axis.

The remote testing device has a second wireless transceiver and remote testing device logic that receives the test command from the host testing device and executes the test command on the system component.

The present invention relates to a light emitting device having an optical part. The optical part comprises at least a first portion comprising a first light input face for receiving first light rays from a first light source and transmitting the first light rays directly toward a light output face so that the light exits the optical part. The optical part further comprises a second light input face for receiving second light rays light from a second light source and transmitting the second light rays toward said light output face so that they are reflected at least one time by total internal reflection on a first zone of said light output face before exiting the optical part through a second zone of said light output face.

A lens for distribution of light predominantly toward a preferential side from a light emitter having an emitter axis. The lens has a faceted output region, a smooth output surface and at least one reflective surface which reflects light through total-internal-reflection (TIR) toward the faceted output region. The faceted output region is formed by pairs of transverse surfaces each surface of which redirects the received light to provide a composite illuminance pattern. The lens may further have faceted input surfaces at least partially defining a light-input cavity about the emitter axis. The faceted input region are formed by pairs of transverse surfaces each surface of which redirects the received light.

The present disclosure relates to a light diffusion characteristic and a light reflection characteristic, and a light source device, a backlight unit, and an electronic device that include the lens. By causing the light emitted from the light source of the light source device to have both light diffusibility and light directivity using the lens including a lower layer portion having a light diffusion characteristic and an upper layer portion having a light reflection characteristic, it is possible to improve a light emission characteristic of the light source device, and when an optical gap is reduced due to the thickness reduction of the backlight unit, the image quality of the backlight unit can be improved.
