20130093862 | AUTOSTEREOSCOPIC DISPLAY DEVICE - A switchable autostereoscopic display device comprises a first LED display panel, an array of non-switchable lens elements and a second LED display panel. This arrangement avoids the need for a switchable lens array to implement a switchable 2D/3D display. The first LED display panel can simply be turned off so that the lens array does not play a role in generating a 3D output. The second LED display panel then produces the desired 2D image. | 04-18-2013 |
20130322090 | COLLIMATOR COMPRISING A PRISMATIC LAYER STACK, AND LIGHTING UNIT COMPRISING SUCH A COLLIMATOR - The invention provides a collimator comprising a first collimator face, a second collimator face, and a stack region. The stack region comprises a first layer having a first prismatically shaped top face with a plurality of | 12-05-2013 |

20150219305 | Lighting device, lens, system and method - A lighting device comprising at least four optical devices. Each optical device has an associated light source and comprises a first surface with a plurality of micro sized facets. Each facet has a respective orientation and said plurality of facets has an optical axis which extends parallel to the normal vector to an average orientation of all said respective orientations. The optical devices are divided over at least two sets of optical devices which are designed to mutually issue a different pattern during operation as the optical devices of different sets are arranged in a mutually alternating manner. | 08-06-2015 |
20150233540 | Optical device, lens, lighting device, system and method - An optical device comprising a first surface with a plurality of micro sized facets, each facet having a respective orientation. Said plurality of facets having an optical axis which extends parallel to the normal vector to an average orientation of all said respective orientations. The plurality of facets comprising at least a first and a second group of facets, each group is formed by a respective number of at least twenty-five compactly arranged neighboring facets. Each group is arranged to generate during operation a respective, mutually identical whole pattern. Each facet in a respective group is arranged to display a sub-pattern of said respective whole pattern. The whole patterns are mutually superpositioned. | 08-20-2015 |
20150241609 | OPTICAL DEVICE, LENS, LIGHTING DEVICE, SYSTEM AND METHOD - An optical device comprising a first surface with a plurality of micro sized facets, each facet having a respective orientation. Said plurality of facets having an optical axis which extends parallel to the normal vector to an average orientation of all said respective orientations. The plurality of micro-sized facets comprises a meaningful pattern forming sub-set of facets. Said sub-set has at least one feature chosen from: equal orientation (tilt and azimuth), similar color, similar marking(scratching, frosting, ribbing), similar spacing with adjacent facets. | 08-27-2015 |
