Abstract: An optical system including a lighting component and a switchable diffuser in optical communication with the lighting component. The optical system may further include a low absorbing optical component. At least one outer surface of the switchable diffuser and/or the low absorbing optical component includes light redirecting structures. When the switchable diffuser is in a first state and the optical system produces a light output, the light redirecting structures are configured to increase the full width at half-maximum (FWHM) of the light output of the optical system in at least one direction by at least 5 degrees relative to that of an otherwise equivalent optical system that does not include the light redirecting structures.

Abstract: A light emitting device includes a plurality of light emitting elements and a light controller. The light emitting elements emit lights. The light controller is disposed on the light emitting elements for the lights passing through to form output lights, and the light controller is switchable in a first state and a second state. A sum of an intensity of the output lights in the first state is greater than a sum of an intensity of the output lights in the second state in an angle ranged from 80° to 100°.

Abstract: A driving apparatus according to an embodiment includes an arm, an operation target, and a brake unit. The arm has one end supported by a support mechanism, and includes an electric driving source. The operation target is attached to the other end of the arm, the other end being an end on the opposite side of the one end, and is enabled to be pivoted by the driving source about one rotational axis intersecting with a direction from the one end to the other end. The brake unit secures immobility of a target gear that is a gear disposed in the arm, and that is a gear being rotated as the operation target is pivoted, when the power supply to the driving source stops.

Abstract: A light source is provided with a digitally addressable lampshade that includes a plurality of regions of controllable opacity. Systems and methods are described for controlling the digital lampshade. In an exemplary embodiment, an addressable lampshade effects a time-varying pattern of changes to the opacity of the regions to generate a lamp identification pattern. A lamp is identified from the patterns by a camera-equipped mobile device. The mobile device then causes the identified lamp to generate a position-determining pattern of light. The mobile device determines its own position relative to the lamp based on the pattern of light received by the camera. The mobile device then instructs the digital lampshade, according to user input, to allow illumination or to provide shade at the determined position of the mobile device.

Abstract: Light-emitting component includes a light source and a dimming element arranged downstream of the light source in a radiation direction. The dimming element includes a dimming layer. The light source includes at least one emitter which is configured to emit light. A brightness of a light emitted by the light-emitting component is adjustable. The brightness is partially adjustable by way of a pulse width modulated and/or amplitude modulated operating signal for the emitter, and the brightness is partially adjustable by way of partial absorption and/or reflection of the light emitted by the emitter in the dimming element. A dimming capability of the dimming layer increases along an extension direction transverse to the radiation direction. The dimming layer is displaceable along the extension direction relative to the light source. A degree of absorption and/or reflection of light emitted by the emitter is variably adjustable.

Abstract: An illuminating, spinning device that includes a housing containing a motor that is electrically connected to a power source and a shaft that extends vertically from the motor. A printed circuit board is connected to the shaft and contains a LED display secured thereto. A base is also connected to the shaft, preferably atop the printed circuit board, and the base and the printed circuit board rotate about the shaft in synchronization. An object is secured to the base adjacent to an LED. The LED display produces a moving animation when rotating about the shaft. The base, object and printed circuit board are further surrounded by an enclosure.

Abstract: The present disclosure provides a pattern projecting lamp and a motor vehicle-in particular, a motor vehicle comprising a pattern projecting lamp. The pattern projecting lamp comprises an optical module configured to provide a projection light beam having a pattern, a support comprising a base and a rotary arm connected rotatably to the base, wherein the optical module is disposed in the rotary arm, and the rotary arm is provided with a light exit for the projection light beam to be emitted through. The pattern projecting lamp can project a light beam having a predetermined pattern at a suitable angle, as tailored to display additional information or provide auxiliary illumination on the vehicle body of the motor vehicle or at a peripheral region of the motor vehicle.

Abstract: A light source assembly for use by a user includes a housing assembly and a moving beam light source. The moving beam light source is positioned substantially within the housing assembly. The moving beam light source generates a source output beam that is directed away from the housing assembly at an angle relative to a rotation axis as a moving output beam while being rotated about the rotation axis. The moving beam light source is a non-visible light source that generates the source output beam having a center wavelength that is outside a visible light spectrum.
