    摘要： The present invention addresses the problem of providing a video display device that projects and displays video including starry sky images onto a target surface, that can reproduce the twinkling of stars and that can more faithfully reproduce an actual starry sky. Provided are a light source, a projection lens, a starry-sky projection negative plate, a twinkling negative plate with uneven light-transmitting properties, a starry-sky-end support unit that supports the starry-sky projection negative plate in a location onto which light from the light source is radiated, a twinkling-end support unit that supports the twinkling negative plate between the starry-sky projection negative plate and the projection lens or between the light source and the starry-sky projection negative plate, and an actuation mechanism that rotationally actuates, by power from an actuator, the starry-sky projection negative plate in a state of being supported by the starry-sky-end support unit and the twinkling negative plate in a state of being supported by the twinkling-end support unit. Light that has penetrated the starry-sky projection negative plate and the twinkling negative plate is radiated onto the target surface via the projection lens.

    摘要： A laser projection light includes a housing defining a light outlet window; a grating assembly near the light outlet window, a first laser device, a second laser device, a optical lens used for reflecting a part of laser light from the first laser device along a first direction and permitting the other part of the laser light to pass through, a first optical reflector used for reflecting laser light which has passed through the first optical lens, a second optical reflector located in the first direction, a third optical reflector configured in the second direction, and one or two drive devices having two drive shafts connected with the second optical reflector and the third optical reflector respectively. The second and the third optical reflectors are driven by the one or two drive devices via the two drive shafts to rotate synchronously or unsynchronously.

    摘要： A lighting system for providing a daylight appearance and a luminaire are provided. The lighting system comprises a plurality of light emitters and a plurality of optical elements. Said plurality of light emitters emit a wide light beam. Each optical element of at least a subset of the plurality of optical elements is related to a light emitter of the plurality of light emitters, thereby forming a pair. For each pair it applies that if a light emitter of a pair is arranged in a first relative position with respect to the optical element of said pair, the light emitter and the optical element are configured to emit the wide light beam, and if the light emitter of the pair is arranged in a second relative position with respect to the optical element of said pair, the optical element is configured to collimate a portion of the wide light beam to obtain a collimated light beam, and the optical element is configured to absorb another portion of light of the wide light beam in a predefined spectral range to obtain a blue light emission at light emission angles at least outside the collimated light beam.
