    摘要: Light directing film structure employing at least two layers having different refractive indices and forming a continuous corrugated boundary between major surfaces of the film. The corrugated boundary forms a plurality of alternating facets forming different dihedral angles with a prevalent plane of the film structure. The facets may longitudinally extend along an arcuate or circular path. Light received by a major surface of the film structure is internally redirected by interacting with the facets of the corrugated inter-layer boundary and may be emitted from the opposing major surface towards a new propagation direction which is different from the original propagation direction.

    摘要: A structurally reinforced illumination panel which includes a multiwall structural panel having a pair of optically transmissive sheets joined using transverse ribs that define a series of linear hollow chambers. The linear hollow chambers extend parallel to each other between opposite edges of the panel. The panel further includes two or more strips of a thin and flexible substrate material positioned within the respective chambers, and two or more linear arrays of electrically interconnected LED sources which are distributed over a length of the respective strips and mounted to the surfaces of the strips. A thickness of the optically transmissive sheets is less than 1 mm, and thickness of at least one of the transverse ribs is less than the thickness of the optically transmissive sheets.

    摘要: A retroreflective sheeting which comprises a top transmissive layer including a plurality of parallel channel formed perpendicular to a surface of the layer, and a reflective bottom layer including a specular surface or a corrugated transmitting surface. The corrugated surface includes a plurality of linear prismatic elements extending perpendicular to the channels of the top layer. The top and bottom layers reflect light in orthogonal directions and act cooperatively to retroreflect incident light back toward the source, particularly at high incidence angles.

    摘要: Wide-area solid-state illumination devices and systems employing a light guide formed by a sheet of an optically transmissive material and selectively patterned in designated areas. Printed light extraction features are used to form a plurality of patterned areas are separated from each other and from edges of the light guide by separation areas which are generally free from the light extraction features. One or more light emitting diodes (LEDs) is optically coupled to the light guide and provides a light source. The light guide is sandwiched between a front sheet and a reflective back sheet. The front sheet includes opaque areas and a plurality of optically transmissive areas disposed in registration with the patterned areas.

    摘要: A stepped light guide illumination system employing a planar sheet of an optically transmissive material having a stepped light guiding structure and one or more parallel arrays of channels. Light is input into the stepped light guiding structure using a number of light sources, such as LEDs, located within the channels and coupled to the stepped light guiding structure at multiple locations. Light is extracted from the stepped light guiding structure by two-dimensional patterns of light extraction features provided within the parallel channels and in surface areas of the stepped light guiding structure located between the parallel channels.

    摘要: Wide-area solid-state illumination devices and systems employing a thin and flexible sheet of an optically transmissive material having at least one broad-area surface patterned with light scattering surface microstructures such as microdots of a non-absorbing UV curable ink. Light is input into the thin and flexible sheet using a number of compact solid-state light sources, such as LEDs, optically coupled to one or more edges or to one or two of the broad-area surfaces defining the thin and flexible sheet. Each surface microstructure forms a semi-opaque layer that extracts light from the thin and flexible sheet and causes light emission from both opposing broad-area surfaces of the sheet.

    摘要: A retractable window covering for natural illumination of building interiors by redirecting the incident daylight at angles that promote its deeper penetration into the interior space. The window covering comprises an optically transmissive, flexible polymeric sheet having reflective surfaces incorporated into its material and configured to redirect at least a portion of light propagating through the sheet towards a desired direction. The window covering is operable from a closed to an open position so as to increase or decrease the amount of redirected and/or admitted light.
