A solar mounting frame for a ventilator apparatus includes: a solar mounting frame having four sides mounted to the ventilator; and a side solar mounting frame having two L-shaped angle rails to mount a solar panel.

A ceiling illumination window is provided with a transparent prism, and a reflecting member provided on a second edge of the transparent prism. Further, the transparent prism is installed in such a way as to enable light incident thereon at an angle, relative to a normal line to first and second transparent plates, that is at least equal to a prescribed angle to be reflected at a third edge using a critical angle. In addition, when light is incident at an angle at least equal to the prescribed angle relative to the normal line, the transparent prism emits the light toward an indoor ceiling side using at least two types of optical path having different numbers of reflections, using reflection at least one of the transparent prism surface and the reflecting member, and when light is incident at an angle less than the prescribed angle, the transparent prism allows the light to be transmitted through the third edge.

A translucent construction element comprising a layer of translucent substrate, which contains a surface structured with nanoplanes of inclined angle relative to the substrate plane, and coated with an interrupted metallic layer covering at least a part of said nanoplanes, is characterized by a high density of interruptions in the metallic layer of low thickness; the periodicity of interruptions in the metallic layer generally is from the range 50 to 1000 nm and the thickness of the metallic layer typically is from the range 1 to 50 nm. The construction element may be integrated, for example, into windows, plastic films or sheets or glazings, especially for the purpose of light management.

This invention presents a solar light collecting and guiding system for stabilizing the output light intensity, wherein the system comprising an array of converging lenses and optical fibers for collecting light focused by converging lenses. The fibers and the lenses are in one-to-one correspondence wherein the input end of an optical fiber is located in the focus position of the corresponding converging lens, and the axis of the optical fiber overlaps with the principal axis of the corresponding converging lens. The system is equipped with a sunlight tracking positioning device for synchronized motion, wherein the device is applied to tracking the sun light ray vertical incident into the central converging lens. The system has the function of outputting stable light intensity, that is, it can effectively reduce the variation of the collecting efficiency caused by the positioning deviation between the incident angle of sunlight and the designed input angle.

The lighting device includes a lighting film including a prism layer configured to emit incident light toward a prescribed direction as emitted light and a double-sided adhesive adhering to at least a part of an outer periphery of the lighting film and including both surfaces having adhesiveness on a side of the incident light and a side of the emitted light, wherein at least one of a peeling strength and a shear bonding strength on the side of the incident light is less than that on the side of the emitted light.

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.

A lighting device capable of manipulating a wider range of parameters to reproduce various light sources. A light source unit includes, for example, a liquid crystal panel and a backlight, and each pixel is a light source capable of adjusting innumerable hues and intensities capable of adjusting hue and intensity. A lenticular lens includes an array of a plurality of lenticules, and is arranged such that a plurality of light sources capable of adjusting hue and intensity is associated with each lenticule. In addition, on the outer periphery of the cylindrical portion of each lenticule, a partition is formed to block emission light from the pixel below the adjacent lenticule, thereby preventing repetition.

An optical article for illuminating building interiors including a reflective grid and a light diffusing element positioned between the reflective grid and a light source. The reflective grid includes one or more arrays of transverse reflective surfaces and is configured to partially transmit and partially redirect incident light over a broad angular range.

A daylight redirecting window film formed by a flexible multi-layer film laminate with a total thickness of less than one millimeter and configured to be applied to an indoor-facing window surface of a building facade. The window film includes a pair of outer film substrates flanking a light redirecting core layer. The core layer includes a parallel array of channels defining total internal reflection (TIR) surfaces and linear optically transmissive structures protruding transversely thought the core layer and bonded to the outer film substrates. A light output surface of the outer film substrate which is disposed on an indoor-facing side of the laminate includes a two-dimensional pattern of light scattering microstructures which are configured to spread light at least in a plane that is perpendicular to the channels. The TIR surfaces intercept and reflect a portion of sunlight propagating through the core layer such that the window film redirects that portion of incident sunlight towards a plurality of divergent directions, forming relatively high bend angles.
