Abstract:
Generally plano rectangular louvers are capable of being ganged in a stacked tiltable array to enhance light re-direction when titled to follow the solar elevation. Combinations of features and optical characteristic avoid optical artifacts and enhance efficiency of light utilization and manufacturing. Different louvers can be combined in alternative ways in such arrays.
Abstract:
An optical article for directing and distributing light including an optically transmissive layer having one or more arrays of TIR channels and a light diffusing element disposed in optical communication with the optically transmissive layer. The TIR channels define reflective surfaces extending perpendicular or near-perpendicular to a prevailing plane of the optically transmissive layer. The TIR channels and the light diffusing element operate concurrently to redirect and redistribute a beam of light received from a light source such as daylight or an LED over a broad angular range.
Abstract:
The present disclosure relates generally to light management constructions comprising microstructured prismatic elements useful in the preparation of room-facing light redirecting films having reduced glare.
Abstract:
A lighting system comprising: a duct providing a light transport passage for transporting light along a propagation direction parallel to a longitudinal axis of the duct, the duct comprising one or more light output surfaces through which light may be emitted, a light collimator having an input end and an output end, a light source arranged to direct light into the input end of the light collimator, a heat sink thermally coupled to the light source, and driver circuit for powering the light source, wherein at least one of the light collimator, light source, heat sink and driver circuit is arranged away from the longitudinal axis of the duct.
Abstract:
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 the light transmission portions including a portion that is convex upwards; 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.
Abstract:
Solar light redirecting glazing units include light redirecting and light diffusing constructions. The solar light redirecting glazing units may include a glazing substrate, a visible light diffusing layer, and a light redirecting layer oriented such that incoming solar light contacts the visible light diffusing layer before contacting the light redirecting layer. The solar light redirecting glazing units may include a glazing substrate, a patterned visible light diffusing layer, and a light redirecting layer. The solar light redirecting glazing units may include two glazing substrates separated by an intervening space with a solar light redirecting layer disposed on one glazing substrate, and a visible light diffusing layer disposed on the other glazing substrate.
Abstract:
The present invention refers to a system including light processing elements, arranged in a respective installation area and combined with a respective construction, at least partially above and/or next to an occupational or passage space, whereby said light processing elements or respective constructions produce a general light distribution over said occupational or passage space, that is more favorable in terms of visual performance and comfort, and that may assist and adjust to activities requiring different levels thereof. The inventive system is used for energy and/or information conversion and distribution, as part of one construction or clusters of constructions, for example disposed along traffic ways.
Abstract:
Lighting devices and methods for providing daylight to the interior of a structure are disclosed. Some embodiments disclosed herein provide a daylighting device including a tube having a sidewall with a reflective interior surface, a light collecting structure, and a light reflector positioned to reflect daylight into the light collector. In some embodiments, the light collector is associated with one or more light-turning and/or light reflecting structures configured to increase the amount of light captured by the daylighting device. Optical elements may allow for the absorption and/or selective transmission of infrared light away from an interior of the daylighting device.
