    摘要： A projector includes a light source, an integrating rod, an image panel, a beam shaper, and an actuator mechanically connected to the beam shaper. The image panel is configured to display an image at a displayed aspect ratio. The beam shaper includes multiple prisms shaped and oriented such that when the beam shaper intersects an optical path of the illumination between the integrating rod and the image panel, the illumination transmitted by the beam shaper is collinear with the illumination incident on the beam shaper. The actuator is configured to switch the projector between (i) a first configuration, in which the beam shaper does not change an aspect ratio of the illumination, and (ii) a second configuration, in which the beam shaper intersects the optical path between the integrating rod and the image panel and changes the aspect ratio of the illumination.

    摘要： An artificial and an artificial skylight is provided. In particular a device is provided that includes a collimating lens having a focal plane and a focal point. The focal plane is flat or curved dependent on given optical properties of the lens. The device further includes a sheet having a lens-facing front side and an opposing back side. The sheet is semi-transparent and has an image thereat, at least at the lens-facing front side. The image is located at about the focal plane of the lens. The device further includes at least one lamp located at the back side of the sheet, the sheet being between the collimating lens and the at least one lamp. The at least one lamp is configured to emit light towards the back side of the sheet, at least a portion of the light transmitted through the sheet towards the collimating lens.

    摘要： The invention relates to a wavelength conversion element, comprising: a phosphor layer comprising one or more phosphors and a first host material; and a particle layer comprising one or more dielectric interference particles and a second host material, wherein the phosphor layer is substantially free of dielectric interference particles and the particle layer is substantially free of phosphors. The one or more dielectric interference particles are formed from alternating thin film layers of at least one high index material and at least one low index material, and a high index material is a material with a lower speed of light when light passes through the material and a low index material is a material with a higher speed of light when light passes through the material. Further a method for generating white light is disclosed.
