The light emitting device includes a light-emitting element having, on a substrate, a first electrode, a light-emitting layer, and a second electrode in order from the substrate side. The substrate has a first three-dimensional structure including a plurality of projections in nano order on the surface on the first electrode side. At least the first electrode out of the first electrode, the light-emitting layer, and the second electrode has a second three-dimensional structure modeled on the projections in the first three-dimensional structure on the surface on the side opposite to the substrate one another. | 06-10-2010 |
20120033302 | OPTICAL ELEMENT, METHOD OF MANUFACTURING OPTICAL ELEMENT, ILLUMINATION DEVICE, WINDOW MEMBER, AND FITTING - An optical element includes a first surface, a second surface positioned to face the first surface, and a plurality of reflecting surfaces arrayed in a first region defined by the first surface and the second surface, wherein the reflecting surfaces have a first length in a first direction vertical to the first surface and are arrayed at a pitch in a second direction perpendicular to the first direction, light incident on one of the first surface and the second surface is reflected by the reflecting surfaces toward the other surface, and predetermined parameters satisfy predetermined relational formulae representing conditions for ensuring total reflection at the reflecting surfaces and for avoiding total reflection at a light emergent surface. | 02-09-2012 |
20120092756 | OPTICAL BODY, OPTICAL BODY MANUFACTURING METHOD, WINDOW MEMBER, AND OPTICAL BODY ATTACHING METHOD - An optical body including an optical layer having a belt-like or rectangular shape and having an incident surface on which light is incident, and a reflective layer formed in the optical layer and having a corner cube shape, wherein the reflective layer directionally reflects the light incident on the incident surface at an incident angle (θ, φ), and a direction of a ridge of the corner cube shape is substantially parallel to a lengthwise direction of the belt-shaped or rectangular optical layer. θ is an angle formed by a perpendicular line with respect to the incident surface and the incident light incident on the incident surface or reflected light emerging from the incident surface, and φ is an angle formed by the ridge of the corner cube shape and a component resulting from projecting the incident light or the reflected light to the incident surface). | 04-19-2012 |
20130033873 | OPTICAL DEVICE AND ILLUMINATING DEVICE - To provide an optical device which is capable of improving a light-introduction efficiency, and which may be made thinner. The optical device according to an embodiment of the present invention includes a structural layer including a plurality of reflection surfaces, which reflect light entering the light-incident surface toward the light-output surface. The above-mentioned reflection surface has a first length (h) in the X-axis direction. The reflection surfaces are arrayed in the Z-axis direction orthogonal to the X-axis direction at pitches (p). The reflection surfaces satisfy a relation of h=(2n−1)·p/tan θ, where θ is indicative of an incident angle of light with respect to the X-axis direction, the light being light travelling on an XZ plane out of light entering the reflection surface, and n is indicative of the number of reflection of incident light by the reflection surface, the angle θ being any angle satisfying the range of 6.5°≦θ≦87.5°. | 02-07-2013 |
