摘要： A lighting system for an indoor room or space is designed to provide a diffuse, glare free source that illuminates the room from the cornice, or a similar location around the join between the walls and ceiling. This may be achieved via a direct source of illumination at the cornice location, or by projecting illumination from a remote source. The lighting system is further designed to allow for illumination of certain areas of the cornice, and hence the room, whilst leaving other parts dark. There are multiple advantages of an adaptable system such as this, but in particular the lighting conditions can be adjusted for optimum lighting levels, for example dimming selected areas when viewing a television.

摘要： A lamp comprises a thin layer of phosphor (105,113) which is irradiated (46), for example by ultraviolet radiation, by a source which typically comprises a laser diode and a condenser (101,111). This causes the phosphor (105,113) to emit visible light with a Lambertion-type emission pattern. An optical system such as a reflector (102,115) concentrates the light from the phosphor (105,113). The phosphor (105,113) is thermally connected to a heatsink (103,116), of example by a plate (114) of sapphire glass, so as to dissipate the heat produced by the phosphor (105,113). The phosphor (105) may be mounted on a plane reflector (104) disposed on or comprising the heatsink (103) and facing a curved reflector (102) and the radiation source. Alternatively, the optical system may have an optical axis and the phosphor (113) may be substantially flat and inclined with the respect to the optical axis.

摘要： An optical device comprises an input polarizer 4, a patterned retarder 5 and an output polarizer 12. The retarder 5 has regions 8 and 9, at least one of which alters the polarization of light from the input polarizer 4. The output polarizer 7 has a transmission axis 12 such that light passing through the regions 8 and 9 of the retarder 5 and through the output polarizer 7 is matched in amplitude, phase and polarization. Such a device may be used as a switchable parallax barrier with an LCD 2 to provide a display which is switchable between an autostereoscopic 3D mode and a 2D mode with the 2D mode having more uniform intensity across the display.

摘要： A parallax barrier comprises a plurality of parallel vertical apertures or apertures. In a direction transverse to the apertures, the apertures have an optical transmission function which comprises a plurality of sub-apertures so that the function varies in this direction. In general, the function is constant in a direction parallel to the apertures or apertures. Such a barrier may be used with a spatial light modulator such as a liquid crystal display to form an autostereoscopic 3D display.

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.

摘要： An optical device directs light from a light source 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. This device includes a first optical element which converges light from the light source towards an inner portion of the region to be illuminated and a second optical element which diverges part of the light from the first element 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. The second optical element may have a concave multiple-faceted surface comprising plane facets in the shape of an open-base inverted truncated pyramid, contiguous sector-shaped facets, at least some of which are concave, or a face divided into an elongate portion disposed between first and second diverging portions.
