摘要： The invention provides an autostereoscopic display device having an adjuster for adjusting the direction of a light beam (5). The adjuster (1) has an off-state and on-state and comprises a stack (10) of layers. The stack (10) comprises a first solid material layer (100) having a first optic axis (111), a second solid material layer (200) having a second optic axis (211), and switchable birefringent twisted nematic liquid crystal material (30) or chiral nematic liquid crystal material. Further, the stack includes a first interface (130) between the first solid material layer (100) and birefringent material (30) and a second interface (230) between the second solid material layer (200) and birefringent material (30). In the off-state, the birefringent material (30) at the first interface (130) is configured to have an optic axis parallel to the first optic axis (111) and the birefringent material (30) at the second interface (230) is configured to have an optic axis parallel to the second optic axis (211). In the on-state, the birefringent material (30) at the first interface (130) is configured to have an optic axis perpendicular to the first optic axis (111) and the birefringent material (30) at the second interface (230) is configured to have an optic axis perpendicular to the second optic axis (211).

摘要： A multi-view display is switchable between single view and multi-view modes, and uses lenticular means (9) arranged over the display panel which comprise birefringent electro-optic material (62) adjacent a non-switchable optically transparent layer (60). The non-switchable optically transparent layer (60) has a refractive index (n) substantially equal to the extra ordinary refractive index of the birefringent electro-optic material (62).In the single view mode, the birefringent electro-optic material (62) defines a non-switched state, and the polarization (64) of the light output from the display panel and incident on the lenticular means is linear and aligned with the optical axis of the birefringent electro-optic material (62) at the surface where the display output light is received. In the multi-view mode, the birefringent electro-optic material (62) defines a switched state in which the optical axis is aligned perpendicularly to the display output surface.

摘要： The invention relates to a luminaire for road illumination, said luminaire (1) comprising a housing (3) containing a light source (5) provided with optics (6). The luminaire further comprising a sensor unit (7) adapted to measure optical properties of the surrounding of the luminaire and a calculation unit adapted to calculate the parameters for controlling the light output of the luminaire based on the optical properties measured by the sensor unit. According to the invention, the sensor unit is adapted to measure specular and diffuse reflection properties of the surrounding of the luminaire. These optical properties allow determining the type of weather or the road condition and adjustment of the light output of the luminaire, thus improving the road safety.

摘要： According to an aspect of the invention, a lighting device (100) for illuminating a secondary surface (200), thereby providing indirect illumination via reflection from the illuminated secondary surface is provided. The lighting device comprises a light source, a collimator arranged to collimate light from the light source, and redirecting means (120) arranged to redirect at least a portion of the collimated light into a range of directions towards the secondary surface. The intensity of redirected light increases with the angle of the direction of the redirected light relative to a normal to the secondary surface from a first intensity value to a second intensity value. The ratio of the second intensity value to the first intensity value is between 25 and 400. The present invention uses the concept of shaping the light intensity distribution of the lighting device in order to increase the possible illumination area of the lighting device.
