摘要： A backlight is provided for illuminating an at least partially transmissive display. The backlight includes a light source. A light guide receives the light from an edge surface and guides the light by total internal reflection. Groove structures which are located on at least one of the major surfaces of the light guide permit redistribution of light around obstacles that may be present within the light guide structure, thereby maintaining brightness uniformity of the backlight or illumination panel.

摘要： A light output arrangement is provided and may be used as a backlight for a display. The arrangement comprises a bendable light-outputting layer (51), for example, comprising a light-guide, and a bendable light-directing layer (50), for example, comprising a lens array. The layers (50, 51) are fixed together so as to prevent relative lateral movement at the mid-points but otherwise are constrained to bend in conformance with each other. The light-directing layer comprises a plurality of structures, such as lenses (81), which cooperate with, for example, light extraction features (80) in the light guide (51) so as to direct light output from the light-directing layer (50) in substantially the same direction (82, 83) irrespective of bending of the layers (50, 51).

摘要： A backlight is provided for a direct-view display. The backlight comprises a plurality of discrete light sources (11), such as light emitting diodes, spaced from a diffuser (5). The light sources are arranged as sets cooperating with a mirror structure (101), which surrounds the set to form a region. The regions substantially tessellate the area of the backlight. Each mirror structure (101) comprises a plurality of mirror segments which are curved and concave in cross-section perpendicular to the diffuser (5). The mirror segments extend from around the light sources (11) towards the diffuser (5). The edges of adjacent mirror segments of adjacent regions meet at a meeting line such that all of the meeting lines are at the diffuser (5) or between the diffuser (5) and the light sources (11).

摘要： An illumination system comprises at least one light source (2) and a light-guide (1). A first part of the light-guide (1) is defined by a surface (12) for light emission and a back surface (13), and a second part of the light-guide is defined by a light receiving surface (14) and a light reflecting surface (15). The light source (2) is disposed adjacent or substantially adjacent to the light receiving surface (14), and light from the light source enters the light-guide through the light receiving surface (14), and is reflected by the light reflecting surface (15) into the first part of the light-guide. Light is emitted from the waveguide through the surface (12) for light emission, and may be used to illuminate, for example, a display device placed over the surface (12) for light emission. The light source and the light receiving surface are on the same side of the waveguide as the surface for light emission.

摘要： An optical device is provided for directing light from a light source (1) to a region of space, such as the field of view of a camera when the optical device is used as a camera flash unit. The device comprises a first optical element (3) which converges light from the light source (1) towards an inner portion of the region to be illuminated. The device also comprises a second optical element (5) which diverges part of the light from the first element (3) outwardly towards an outer portion of the region to be illuminated so as to achieve adequate central illumination with improved uniformity of illumination across the region to be illuminated. In one example, the second optical element (5) has a concave multiple-facetted surface comprising plane facets (7-11) in the shape of an open-base inverted truncated pyramid. In another example, the second element (5) has a multi-facetted surface comprising contiguous sector-shaped facets (31-38), at least some of which are concave. In yet another example, the second element (5) has a face divided into an elongate portion (40, 60) disposed between first and second diverging portions (41, 42, 61, 62). In a further example, the second optical element (5) is reflective and reflects part of the incident light via the first optical element (3).

摘要： A light source system comprising projection optics, which are capable of producing a far-field image of a light source. The light source comprises a fluorescent medium that when illuminated by light from laser emitters of a first waveband emits light of a second or more wavebands of longer wavelength. The resulting light emission produces a colour perceived as white. The light source is illuminated by a plurality of laser emitters arranged to illuminate the light source in an array-like manner. Control of the output of one or more of the laser emitters results in a variation of the spatial emission distribution from the light source and hence a variation of the far-field beam spot distribution via non-mechanical means.

The backlight comprises an array of primary light sources that emit downwards towards an arrangement of curved mirror surfaces. The light reflected by the mirror surfaces is collimated by an arrangement of lenses. The mirror surface shape, lens shape, primary light source positions and the separation between the lens and mirror surfaces are chosen to ensure a high degree of spatial uniformity as well as collimation.

摘要： A phosphor-based multi-coloured display is provided which includes a spatial light modulator comprising an addressable array of apertures each corresponding to a respective sub-pixel in the display; an array of phosphor regions each indexed to a corresponding aperture of the spatial light modulator; and a backlight which provides quasi-monochromatic light to phosphor within each of the phosphor regions. The phosphor within each of the phosphor regions, upon being excited by the quasi-monochromatic light of the backlight, emits light having a colour different from a colour of the quasi-monochromatic light, through the corresponding aperture of the spatial light modulator.

摘要： An optical device is provided, for example for use as a brightness enhancing film in a display. The device comprises a sheet (31) carrying a plurality of light-concentrating elements in the form of prism-like structures (171). The sheet (31) is non-flat, for example by being bent or curved, in one direction. Each of the prism-like structures (171) has first and second surfaces (34, 35) extending from the sheet (31) and intersecting at a line (33). A line (32) parallel to the viewing direction and passing through the intersection line (33) bisects the opposite surface (36) where it intersects (38) the film (31). When used in a display, such a device provides improved and uniform display brightness across a display of curved or other non-flat shape.
