The present disclosure provides lamination transfer films and use of the lamination transfer films, particular in the fabrication of architectural glass elements, such as those used in Insulated Glass Units (IGUs). The lamination transfer films may be used to transfer functional layers and structures. The lamination transfer films may include a support film that can be removed during the transfer process, and the transferred materials are primarily inorganic. The resulting transferred structures on glass generally have high photo- and thermal-stability, and therefore can successfully be applied to the glass surfaces that are interior to the cavity within an IGU. The lamination transfer films can also be patterned such that macroscopic patterns of microoptical elements can be applied on a glass surface.

Microoptical layers, glazing units including the microoptical layers, and transfer tapes that may be used to provide the microoptical layers are provided. The transfer tape includes a removable template layer having a structured surface, a backfill layer having a first surface disposed on at least a portion of the structured surface of the template layer, and a microstructured surface opposite the structured surface. The microstructured surface together with a layer disposed on the microstructured surface is an anisotropic diffuser.

An object is to provide a daylighting sheet which efficiently performs daylighting and in which, when the daylighting sheet is applied to a window of a building or the like, it is possible to see an outdoor side. The daylighting sheet includes a translucent base material layer; and a light deflection layer that is formed on the base material layer, and the light deflection layer includes: light transmission portions that are aligned along one surface of the base material layer so as to be able to transmit light, each of which including a groove at a portion being in a light entering side in a position where the light transmission portion is arranged in the opening portion of a building; and light deflection portions that are formed between the light transmission portions and filled with a material whose refractive index is lower than that of the light transmission portions.

There is provided a light collecting device comprising a concave portion for receiving incoming light. The concave portion comprises a reflective inner surface for directing at least partly the incoming light toward a focal spot, which is defined by a geometry of the concave portion. A light guide holder is held in place at the focal spot and holds a light-receiving end of a light guide, inside its annular shape. It holds the light-receiving end toward the concave portion to substantially capture the incoming light directed toward the focal spot. The concave portion can be a dish or a lamp reflector. The light guide holder can be held in place by arms having pads that rest on or hold the concave portion.

A light-diffusion member includes a plurality of cylindrical lenses arrayed in a prescribed direction, wherein the cylindrical lenses are arrayed in a first direction and extended in a second direction that is perpendicular to the first direction, the cylindrical lenses each have a curved lens surface, and the lens surface has a height that continuously changes with a prescribed period in a cross-section of the cylindrical lens taken along a second imaginary plane that is perpendicular to a first imaginary plane containing both the first direction and the second direction and that is parallel to the second direction.

A device comprising a dimmable panel comprising a plurality of individually dimmable cells attached to a window glass, an optical sensor to detect an image of one or more objects, a computation unit, communicably coupled to the dimmable panel and the optical sensor, to: i) cause to darken one or more cells of the plurality of individual dimmable cells of the dimmable panel, ii) cause the optical sensor to capture an image of the one or more objects, and, iii) determine, based on the image, whether a shadow is cast on the one or more objects due to the one or more darkened cells.

An electromagnetic radiation collecting and directing apparatus is described herein. The electromagnetic radiation collecting and directing apparatus facilitates directing light from an exterior of a structure to an interior of a structure. The directed light is then distributed as necessary within the structure for heating, illumination, or is stored for use at a later time.
