    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: A light source (25) for emitting collimated light (29) in particular for a large area luminaire (21) comprises a light guide unit (43) for guiding light by total internal reflection. The light guide unit comprises a plurality of localized light source regions (57) at a main front face (55A) for having light pass there through. The light source (25) further comprises a plurality of light emitting units (41) for emitting light into the light guide strips (91) through respective portions of the at least one coupling face (47) of the light guide unit (43), and a collimation unit (45) extending along the main front face (55A) and comprising a plurality of collimating elements. At least one light emitting unit (41) is configured as a light input coupling assembly (250) to receive collected natural light from a fiber (249) and to provide the received natural light to the light guide unit (43). The light source (25) can be implemented in a sunlight-based illumination system (241) collecting and providing natural light to the light source (25).

    摘要: A lamp includes a variable transmissive film and a light source arranged to transmit light through the variable transmissive film. The variable transmissive film includes an encapsulated dispersion containing a plurality of electrically charged particles and a fluid, the charged particles being movable by application of an electric field and capable of being switched between an open state and a closed state. In some embodiments, one portion of the variable transmission film is in the open state and one portion is in the closed state, thereby allowing light from the source to be shaped, e.g., into a spotlight.
