摘要: Optical constructions use a low index of refraction layer disposed between a low absorption layer and a high absorption layer to increase confinement of light to the low absorption region of the optical constructions. Low index layers can be used in optical constructions that have multi-tiered light confinement. In these constructions, a first tier of reflection is provided when light is reflected at the surface of a low index optical film which is disposed directly or indirectly on a light guide. A second tier of reflection occurs at the surface of a light redirecting film having appropriately oriented refractive structures.

摘要: An illumination device comprising a plurality of solid state light sources and a concentrating wave length converter arranged to inject light from said light sources through at least one entrance surface and to extract wave length converted light from at least one exit surface, comprising a structured layer provided on said exit surface, said structured layer having a structure period less than 5 micrometers, thereby enabling out-coupling through the exit surface by a combination of refraction and diffraction. In a situation where the angle of incidence on a surface is within a limited range, a combination of refraction and diffraction may provide a superior out-coupling from that surface.

摘要: A light emitting device of the disclosure includes a first light source and a second light source; a light-guiding plate having a first main surface and a second main surface that face each other, a first end surface facing the first light source, and a second end surface facing the first end surface and the second light source; a prism sheet disposed to face the first main surface; and a reflection sheet disposed to face the second main surface. The light-guiding plate includes a plurality of first slope sections and a plurality of second slope sections both provided on one of the first main surface and the second main surface, in which the plurality of first slope sections are provided to allow the light-guiding plate to be thinner in a first direction that extends from the first end surface to the second end surface, and the plurality of second slope sections are provided to allow the light-guiding plate to be thicker in the first direction, and each provided alternately with each of the first slope sections in the first direction. A proportion of area occupied by the second slope sections increases in a predetermined range from the second end surface, as a distance from the second end surface increases.

摘要: An optical system for influencing a light has a first optical element (1), by means of which a plane (E) is defined, wherein the first optical element (1) has a lateral edge region (11) designed for the entry of the light, and a second optical element (2), wherein the second optical element (2) is arranged parallel to the first optical element (1) and has a light outlet region (21) for the exiting of the light. The lateral edge region (11) of the first optical element (1) is designed to reduce the glare of or bundle the light in the plane (E), and the second optical element (2) has an elongate lens element (3), which extends along a longitudinal axis (L) and is designed to reduce the glare of or bundle the light in an additional plane (E'), which is oriented at least substantially perpendicularly to the plane (E) mentioned first.

摘要: A transparent display includes a backlight unit (BLU) that includes a light guide plate (LGP). The BLU is configured to allow light to be transmitted from one surface of the LGP to the other wherein, in at least one selected area, the light transmitted across the LGP is not substantially interfered with from the display image such that both a background behind the display and a display image are viewable to an observer.
