The tension assist bracket is adapted to keep the floating pulley bracket fixed during installation and is adapted to be removed after the side panel assemblies are attached at the structural opening and the pair of cables are looped through the first, second, and third pulleys of respective tensioning assemblies and attached to a free end of the shade material.

A daylighting panel for integration into a building or larger vehicle comprises a translucent facade element (800) containing a glass sheet 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 equipped with a luminaire (807), characterised in that the inner walls including the rear end are covered by a reflecting layer (808).

A dimmer mechanism is movable by a motor that is powered by solar-charged supercapacitors between a first configuration, in which the dimmer mechanism blocks little of the interior of a skylight tube to maximize light throughput into a room, and a second configuration, in which the dimmer mechanism blocks more of the interior of a skylight tube to reduce light throughput into the room.

An illuminance obtained by light passed through light diffusion type skylight windows is affected by the weather. This is to solve such problems by polarization of lighting devices and control technology in addition to improvements in the quality of skylights themselves, and the advantages of the high natural lighting offered by light diffusion type skylight windows are now being utilized. A set value that is the result of associating a required work surface illuminance for indoors with the work surface illuminance obtained by light passed through light diffusion type skylight windows and the generated power of a photovoltaic power generation panels is set as a reference for a light adjustment signal. In situations such as winter sunsets and rainy weather which are in a range equal to or less than the set value, light adjustment of lighting devices is performed by a signal transmitted from the photovoltaic power generation panels.

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.

The first and second side panels are positioned parallel from one another and are attached to the arcuate shaped roof panel, wherein one of the first and second side panels defines a cavity configured to receive a television monitor. The floor panel configured to connect the first and second side panels to one another. The front panel removable attached to the arcuate shaped roof panel and the first and second side panels. The back panel positioned parallel to the front panel and attached to the arcuate shaped roof panel and the first and second side panels. Each panel includes one or more of inflatable sections.

A skylight assembly in which the skylight, passing sunlight from a building's exterior to an interior of a building, has a translucent flexible membrane selectively extending across the skylight and having at least one graphical image imprinted on the flexible membrane.

A daylighting device according to an aspect of the invention includes at least a daylighting film that includes a base having optical transparency and daylighting portions having optical transparency and provided on one surface of the base. Each of the daylighting portions has a reflective surface by which light incident on the daylighting portion is reflected and the light reflected by the reflective surface and output from a second surface of the base has a characteristic that the light travels toward a space on a side where the light is incident on the reflective surface, the space being one of two spaces divided by a virtual plane as a boundary which is vertical to the second surface of the first substrate and parallel to a direction of the daylighting portion extending, and intervals s between adjacent daylighting portions are set to various values.

The present invention discloses an improved light transmitting plastic panel (100) used in buildings for providing a variable daylight either during a day or in various areas of the building. The light transmitting plastic panel (100) consists of two transparent plates (102A, 102B) and a plurality of transparent hollow cells of V-type (104A, 104B) and rhombus shaped cells (106) located in between these plates (102A, 102B). In particular, a structure of the hollow cells is a repetitive sequence of one rhombus cell (106) in between two V-type cells (104A, 104B). Further, some of the hollow cells are made opaque with a predetermined pattern. With this specific structure, the variable daylight is achieved based on a time of day. In another aspect of the invention, differential daylight is provided for different areas of the building by forming a non-continuous flow pattern of opaque hollow cells across the length of the light transmitting plastic panel (100).
