An emission enhancement structure having at least one energy augmentation structure; and an energy converter capable of receiving energy from an energy source, converting the energy and emitting therefrom a light of a different energy than the received energy. The energy converter is disposed in a vicinity of the at least one energy augmentation structure such that the emitted light is emitted with an intensity larger than if the converter were remote from the at least one energy augmentation structure. Also described are various uses for the energy emitters, energy augmentation structures and energy collectors in a wide array of fields, especially in the field of solar cells and other energy conversion devices.

A 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. Light directly louvers, films, sheets and panels deploy a grooves that re-direct exterior sunlight for deeper penetration into rooms and building interiors. Absorbing structure are combined with films or panel that while reducing total interior illumination, reduce the potential for annoying glare at low solar elevations.

In various embodiments, a transom light arrangement may include a transom, which is arranged between a construction element and a transom light, a light source arrangement, which is mounted at least one of on or in the transom, with the light source arrangement or the transom defining a horizontal plane, and a screen structure. The light source arrangement and the screen structure are arranged relative to one another and are configured such that a spatial region above the horizontal plane is illuminated using the light source arrangement.

In one aspect, a system for collecting light directed through an architectural opening includes a plurality of optical fibers positioned within the architectural opening. A portion of light from a light source is absorbed by the plurality of optical fibers. One or more optical fibers of the plurality of optical fibers are configured to transmit the absorbed light to one or more light collection elements.

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.

Window glass having sun-facing daylight redirecting optical structures with an embedded surface diffuser patterned on them. The optical structures are generally linear and formed from a repeating unit cell. Each unit cell has a base, two or more peaks opposite the base, and at least one curved side between the base and the peaks. The other sides between the base and the peaks can be substantially straight, curved, or a series of facets approximating a curve.

A daylight illumination system for integration into a building or larger vehicle comprises a translucent facade element (800) containing a glass sheet and a light redirection element (302 or 708), and a light transport channel (801) for guiding light about horizontally into an interior of the building, the light transport channel comprising one opening attached to the interior side of said facade element and at least one opening towards the interior of the building, characterised in that the light redirection element (302 or 708) is formed as a structured polymer film or sheet attached to a glass sheet of the facade element (800) and is configured for changing the direction of incident light into the about horizontal light transport channel.
