20080196607 | Method and arrangement for manufacturing optical products with complex three-dimensional forms - A method, an arrangement and computer program product for manufacturing micro-optic surface design with complex, variable three-dimensional forms. A step embossing, step imprinting, a chip bonding or a corresponding device capable of patterning the surface of a target substrate is obtained. The target substrate whereto the micro-optic structures shall be patterned is obtained. A plurality of different stamping tools operable with the device is obtained. Each stamping tool includes one or more surface relief forms defining one or more micro-optic structures. A stamping tool is selected from the plurality of stamping tools by the device. The target substrate is embossed with the selected stamping tool as controlled by the device. The selected stamping tool is optionally heated or assisted by at least one ultraviolet light so as to cure the target substrate during or after the embossing. The selecting and embossing steps are repeated until the micro-optic surface design has been completed on the substrate. | 08-21-2008 |
20080225393 | Light outcoupling structure for a lighting device - A diffractive light outcoupling unit for forming a part of a directive light outcoupling system of a lighting device including a plurality of diffractive outcoupling units. The diffractive light outcoupling units each include a carrier element for accommodating a diffractive surface relief pattern, and a diffractive surface relief pattern including a plurality of consecutive diffractive surface relief forms defined on a surface area of the carrier element arranged to couple light incident on the diffractive surface relief pattern outside the carrier element via interaction involving at least two surface relief forms of the plurality of surface relief forms of the diffractive surface relief pattern so as to enhance the directivity of the coupled light. A diffractive light outcoupling system includes a plurality of diffractive light outcoupling units. A lightguide includes the outcoupling system. | 09-18-2008 |
20080266863 | Ultrathin Lighting Element - An ultra thin lighting element including at least one light source.
