摘要： A brightness enhancing structure for a reflective display. A plurality of transparent hemi-beads form a film substantially covering and protruding inwardly from the structure's inward surface. A corresponding plurality of microstructured toroidal lenses are provided on the structure's outward side. Each lens is optically coupled to an adjacent one of the hemi-beads to redirect incident light rays toward the adjacent hemi-bead, such that the redirected light is totally internally reflected by the hemi-bead and reflected back in a direction approximately opposite that of the incident rays. This substantially reduces undesirable dark, non-reflective circular regions of each hemi-bead which would otherwise exist in the absence of this invention.

摘要： An optical switch for controllably switching an interface between a reflective state in which incident light undergoes total internal reflection and a non-reflective state in which total internal reflection is prevented. In one such switch a cell contains a fluid. One side of the cell forms the light incident interface. A membrane is suspended in the fluid. One pair of electrodes is applied to opposite sides of the membrane. Another electrode pair is applied to the cell's interface side and to the cell's opposite side. A variable voltage potential is applied between selected ones of the electrodes. Application of the voltage potential between selected ones of the membrane and cell electrodes moves the membrane into optical contact with the interface, producing the non-reflective state. Application of the voltage potential between other selected ones of the membrane and cell electrodes moves the membrane away from optical contact with the interface, producing the reflective state.

摘要： Image display apparatus incorporating an enclosure having substantially opaque, substantially reflective interior surfaces. A light source emits light rays within the enclosure. An image-bearing surface is mounted in a front portion of the enclosure. The image-bearing surface bears a predefined image having transmissivity and reflectivity characteristics which vary as a function of position on the image-bearing surface, such that a substantial portion of the image is substantially non-transmissive and substantially reflective, and the remaining non-substantial portion of the image is substantially transmissive and substantially non-reflective. Accordingly, substantially all of the light rays which strike the reflective interior surfaces or strike the reflective portion of the image bearing surface are reflected within the enclosure, and substantially all of the light rays which strike the transmissive portion of the inward face are emitted through the image-bearing surface, thereby increasing luminance brightness of the image on an outward face of the image-bearing surface by repeated reflection of the reflected light rays within the enclosure until the reflected light rays strike the transmissive portion of the image-bearing surface.

摘要： A light guide light extraction mechanism can be formed in a predetermined maximum length to yield a predetermined light emission characteristic. Any shorter length segment removed from a predetermined end of the extraction mechanism and installed in a light guide of that shorter length causes the shorter length light guide to exhibit substantially uniform surface brightness. This obviates the need for cumbersome trial and error development of a different light extraction mechanism for each such shorter light guide.

摘要： An outer prism light guide surrounds a cover which in turn surrounds a light source. The outer guide is formed of prism light guide wall material having uniform shape in cross-sections perpendicular to a first octature symmetry direction, with its optical center line parallel to the first octature symmetry direction. Surfaces of the wall material are substantially in octature relative to the first octature symmetry direction. A surface normal vector at any point on any internal surface of the material is either substantially parallel or substantially perpendicular to a first notional line extending from the point through and perpendicular to the optical center line. The cover has cylindrical symmetry about the optical center line to intercept a substantial portion of light emitted by the source. The cover is formed of prism light guide wall material, with surfaces of the cover wall material substantially in octature at any point on the cover relative to a second, spatially variable octature symmetry direction, which, at the point, is perpendicular to the first octature symmetry direction; and, perpendicular to a second notional line extending from the cover point through and perpendicular to the optical center line. A surface normal vector at any point on any outer surface of the cover is either substantially parallel or substantially perpendicular to the first octature symmetry direction. The cover is confined to a region sufficiently close to the optical center line to substantially prevent propagation of light rays incident on an inside surface of the cover to and through the light guide wall material.

摘要： The lighting panel has a first face for receiving light from a source and a second face. The panel includes a first and a second sheet of transparent dielectric material. Each sheet has a smooth surface on one side and is corrugated on the other side. The surfaces forming the corrugations intersect at 90.degree. the smooth surface on the first side is at 45.degree. to the surfaces of the corrugations on the other side of each sheet. The smooth surface of the first sheet forms the first face of the panel, the corrugated surface of the first sheet is adjacent to the smooth surface of the second sheet, with the direction of the corrugations on the second sheet set at a predetermined angle .alpha. to the direction of the corrugations on the first sheet. Light thus enters the smooth surface of the first sheet and emerges from the corrugated surface of the second sheet. The sheets may be substantially planar. At least one of the sheets may also include light release mechanisms. The angle .alpha. may be set at substantially 90.degree., or may be varied to produce a desired light directionality.

摘要： The prism light guide is a longitudinal hollow structure made of transparent dielectric material. The structure has substantially planar inner and outer surfaces which are in "octature". The hollow structure is formed of one or more longitudinal sections which may be bonded together with an adhesive having a refractive index similar to the refractive index of the sections. The cross-section of each section is preferably constant along the length of the section, and the surfaces in each section are flat and polished smooth. One preferred light guide includes a rectangular or square hollow structure made of four longitudinal wall sections bonded together. Each wall section has a planar inner surface and an outer surface having 90.degree. angle longitudinal corrugations. The dielectric material is acrylic plastic or optically clear glass and the light guide includes an outer jacket for protecting the outer surface.

摘要： Sunlight redirector (30) incorporates closely proximate mirror arrays (32, 34) having parallel, uniformly spaced, longitudinal mirror segments (38, 44). Prismatic sheet (36) is positioned behind and closely proximate second array (34). Segments (38) extend in first direction (x). Segments (44) extend in second direction (y) perpendicular to direction (x). Segments (38, 44) have normal vectors (42, 48). Segments (38) are interconnected for simultaneous pivotal movement (40), such that their normal vectors (42) remain parallel. Segments (44) are interconnected for simultaneous pivotal movement (46), such that their normal vectors (48) remain parallel. Arrays (32, 34) redirect incident light toward sheet (36), which redirects the light into a desired fixed direction, e.g. parallel to the sunlight redirector's normal vector (50). Segments (38, 44) may have inward and outward segments (60A, 60B) which can be adjustably positioned to maximize redirection of incident sunlight rays in a desired direction.

摘要： An optical structure placeable between a backlight array of point light sources and a planar display. The structure distributes light emitted by the point light sources to uniformly illuminate the plane of the display, without introducing significant viewing parallax. The emitted light is partially collimated within a preferred angular viewing range, maximizing the display's luminance when viewed from the normal direction. The structure is highly reflective, such that a substantial portion of any non-emitted light rays are internally reflected by the structure, increasing the likelihood that those rays will be subsequently emitted by the structure.
