摘要： A liquid crystal display apparatus (500) including a liquid crystal display (LCD) panel (502), a light emitting assembly (501) arranged to illuminate the LCD panel, and a light conditioning element (510) between the light emitting assembly and the LCD panel. The light emitting assembly includes a planar optical conductor (158) characterized by a length and a width. The optical conductor has a light input surface (225), light transmission control elements (151) and well defined light extracting optical elements (157) configured to redirect light received at the light input surface out from the optical conductor. The light transmission control elements divide the optical conductor into independently operable light emitting regions (152). An LED light source (156) is optically coupled to each of the light emitting regions adjacent the light input surface of the optical conductor. Each LED light source is small relative to the length and width of the optical conductor.

摘要： A lighting assembly that includes a cornuate light guide and an annular light extracting and redirecting member. The light guide has a radial light input surface, an axial light input region, radial light output region and a flared region between input region and output region. Light input at the light input surface propagates to and within the light output region by total internal reflection at major surfaces of the light guide. The light extracting and redirecting member has a light extracting element in optical contact with an annular region of one of the major surfaces of the light output region, and a reflective light redirecting element to axially redirect the extracted light with a defined light ray angle distribution.

摘要： A lighting assemble has an edge-lit light guide having a light output surface through which light is extracted by light extracting optical elements. The extracted light has a maximum intensity at low light ray angles relative to the light output surface. A light redirecting member has an arrangement of light redirecting optical elements configured to redirect the extracted light incident thereon to provide a pattern of redirected light. A light focusing member has light focusing optical elements having an angular acceptance range. The redirected light has light ray angles within the angular acceptance range of the light focusing optical elements and is perceived as a pattern of light. The extracted light not redirected by the light redirecting member has light ray angles outside the angular acceptance range of the light focusing optical elements and is not perceived, or is perceived as background light.

摘要： A lighting assembly includes a light guide and light source. The light guide includes light input regions, at least one of the light input regions associated with an optical modifying characteristic, and the light guide is configured to propagate light by total internal reflection. The light source is located adjacent the light input regions. The light source and light input regions are variably positionable relative to one another to vary a location at which light is incident on the light input regions such that light emitted from the light source is selectively apportioned between the light input regions. A characteristic of the light output from the lighting assembly is modified based on the optical modifying characteristic of the at least one of the light input regions and the relative positioning of the light source and the light input regions.

摘要： Optical elements with small increments in average density are formed in a substrate by laser micromachining using a variable aperture and a pattern mask set of pattern masks each having of shape-defining elements whose density differs among the pattern masks in first density increments. A laser light beam passes through a combined mask formed by the variable aperture and one pattern mask selected from the pattern mask set. The variable aperture controls beam size and the pattern mask spatially modulates its intensity. A focusing element focuses light from the combined mask on a small averaging region of the substrate. Different combinations of the size of the aperture mask and the selected pattern mask are used in combination at respective averaging regions of the substrate. The resulting average densities of the optical elements vary among the averaging regions in increments that are small compared to the first density increments.

The light source is at an apex region between two side surfaces and is configured to input light to the light guide. The side surfaces comprise a stepped reflective side surface extending from the apex region and comprising a first reflective step and a second reflective step, and an output side surface extending from the apex region and comprising a first output region and a second output region. The first reflective step is configured to reflect a first portion of input light through the first output region. The second step is configured to reflect a second portion of input light through the second output region.
