Abstract:
Disclosed is a retractable lighting fixture having a retractable LED lighting layer. One or more optical layers (40, 240A/B, 340A/B, 440) may optionally be provided over the LED lighting layer (30, 230, 330, 430). The optical layer(s) and the LED lighting layer may optionally be movable relative to one another between at least being in an expanded spaced relation to one another and a compressed relation to one another. One or more LEDs (34, 134, 234A/B, 334A/B, 434) on the LED lighting layer may be individually controllable and such LEDs (34, 134, 234A/B, 334A/B, 434) may be selectively extinguished when they are in a retracted position.
Abstract:
A light output sticker (10) comprises a flexible transparent substrate arrangement (11). A plurality of light source devices (14) are provided on or in the flexible substrate arrangement (11). A conductor arrangement (12) comprises conductor lines which connect to the light source devices. An adhesive layer (15) and release liner (16) are provided for attaching the sticker to an external substrate. The applied sticker is substantially transparent. The sticker of the invention avoids the need to embed the LEDs in a glass structure during the manufacturing of the glass. Instead, the LEDs are part of the transparent sticker, which can be added to a glass (or other material) substrate after manufacture of both the sticker and the glass (or other) material to which it is to be attached.
Abstract:
In a stereoscopic display apparatus having optical directory elements such as lenticular elements (4) extending parallel to each other and being slanted at an angle to one of the rows and columns of picture elements the appearance of so called dark bands is prevented by certain combinations of the slant angle and the lens pitch.
Abstract:
A multi-view display (49) is arranged to provide large viewing zones (23, 24) while producing little or no cross-talk. The display may include a barrier (20) comprising a plurality of colour portions (20a, 20b, 20c) that co-operate with colour filters (19a-19f) in a display panel (14) to selectively direct light to the viewing zones (23, 24). A lenticular screen (30) may be arranged to create or image light lines onto imaging units (32a, 32f) of the display panel (14) that are spaced from one another, so that adjacent units (32a, 32f) are illuminated by light from different lenses (30a, 30b, 30c), directed towards different viewing zones (23, 24). A light source (35) may generate the light at positions aligned with boundaries between adjacent lenses (30a, 30b, 30c). The imaging units may be operated so that units (32a, 32b) displaying information for the first viewing zone (23) are separated from units (32d, 32e) displaying information for the second viewing zone (24) by units (32c, 32f) not used to display information. Adjacent columns of units (32a, 32b) may be used to display information to one viewing zone (23). The viewing zones (23, 24) may be enlarged using a scatterer (36). A switchable diffuser (40) or barrier (48) may be provided so that the display (49) can operate in different multi-view and/or single view modes.
