摘要: Proposed is a light emitting apparatus (1) comprising a light source (5) for emitting light and a collimator (40) for arranging the light emitted in an application specific distribution. The light source comprises (i) a semiconductor device (10) capable of emitting light, (ii) a body (20) having a bottom surface (21) adjacent to the semiconductor device (10) and an opposing top surface (22), and (iii) a reflector (30) positioned adjacent the top surface (22). The light emitting apparatus (1) is characterised in that the reflector (30) has a surface larger than the bottom surface (21) of the body (20). This is especially advantageous for creating a given light beam collimation with a smaller collimator or alternatively for creating a collimator producing a significantly narrower light beam.

摘要: An auto-stereoscopic display device which addresses the problem of how to provide an improved three dimensional effect without degrading the resolution of the views. The auto-stereoscopic display device comprises: image forming means having an array of display pixels for producing a display; view forming means positioned in registration with the image forming means and having an array of view forming elements, the view forming elements each being configurable to focus the outputs of groups of the display pixels into a plurality of views projected towards a user in different directions; and view deflecting means positioned in registration with the view forming means, the view deflecting means being arranged to selectably change the directions in which the plurality of views are projected towards the user. The view deflecting means comprise at least one birefringent prism having a first refractive index for light having a first polarization direction and a second refractive index for light having a second polarization direction. The view deflecting means further comprise a polarization switch in registration with the birefringent prism for providing the birefringent prism with display light having the first or second polarization direction. Specific arrangements of the image forming means, the view forming means and the view deflection means provide an even distribution of pixels and virtual pixels associated with the deflected views

摘要: An optical arrangement comprising a light guide (101) having a light-entry portion (103) with a light-entry surface (105), a tapering portion (107) with a light reflecting surface, and a light-exit surface (109). The light-entry portion (103) is arranged to guide light from the light-entry surface (105) in a first direction (x) towards the light reflecting surface (H I), the light reflecting surface being arranged in relation to the first direction (x) so that incident light from the light-entry portion (103) is reflected towards the light-exit surface (109). A light transmitting layer (113) is adapted to transmit light diffusively and arranged to cover at least a portion of the light-entry edge surface (105) of the light guide (101). The arrangement is e.g. suitable for use in a LED based luminaire and allows for efficiency and forming of a light beam able to fulfill glare requirements.

摘要: The present invention relates to an illumination system (200) including a first sub-system (205) comprising a first set (201) of at least two differently colored light sources where the first set (201) has a first spectral distribution, and a first light mixing device (203) arranged in a direction of emission of light from the first set of light sources and configured to mix light emitted by the first set of light sources. The illumination system further includes a second sub-system (206) comprising a second set (202) of at least two light sources where the second (202) set has a second spectral distribution, and a second light mixing device (204), also arranged in a direction of emission of light from the second set of light sources and configured to mix light emitted by the second set of light sources. The light sources are selected such that that the first and the second spectral distribution complement each other, so that a color rendering index (CRI) of light emitted from the illumination system (200) is greater that the CRI of light emitted from each of the sub-systems. Furthermore, the first (205) and the second (206) sub-systems are arranged to emit at least one common color, such as a shade of white.

摘要: The present invention relates to a dual view display device where a display surface is divided into a first and a second sub-section (10a, 10b). A backlighting arrangement is used which provides light with different angular distributions (16a, 16b; 16a′, 16b′) to the different sub-sections. This allows at low cost e.g. in a vehicle the displaying of movies or computer game windows at a part of a display, which part is not visible for the driver of the vehicle.
