    摘要: A waveguide (40; 51; 61), arranged to guide light from at least one light source (53a-c), the waveguide comprising at least one guiding edge (43; 50a-c; 60) adapted to contain the light in the waveguide (40; 51; 61), and an extraction edge (44; 50d) adapted to enable extraction of the light from the waveguide (40; 51; 61), wherein the guiding edge (43; 50a-c; 60) is configured to reflect the light on its way towards the extraction edge (44; 50d). The guiding edge (43; 50a-c; 60) is further configured such that a direction (xr1, Xr2) of reflection of a ray of light impinging on the guiding edge (43; 50a-c; 60), in a given direction (xi) of incidence relative to a general direction (X0) of extension of the guiding edge (43; 50a-c; 60), is dependent on a position (P1, P2) of incidence along the guiding edge (43; 50a-c; 60). The waveguide may be configured such that virtually no light is lost through back-scattering or unintentional extraction or outcoupling through the at least one guiding edge.

    摘要: A window assembly (100,110,120,130) for irradiating infrared light (L) comprises a light guide (5) for infrared light (L), which is formed by a gap between a first transparent substrate (2), having an exterior surface and an interior surface, which faces the light guide (5), and a second transparent substrate (3) substantially parallel to the first transparent substrate (2) and having an exterior surface and an interior surface, which faces the light guide (5) and the interior surface of the first transparent substrate (3). A first and a second reflective layer (12,13), that are both substantially reflective for infrared light (L), extend over the interior surfaces of respectively the first and the second transparent substrate (2,3). The second reflective layer (13) is provided with an opening (21) through which at least part of the infrared light (L) exits the light guide (5). In one embodiment, the window assembly further comprises an infrared light source (1) for directing the infrared light (L) into the light guide (5). In this way the infrared light (L) leaves the light guide (5) in one main direction through the opening (21) of the second reflective layer (13) and through the second transparent substrate (3), thereby generating heat in one main direction only.

    摘要: A display unit comprising electro-wetting pixels (1300) is provided. The inventive pixels (1300) provide bistable or multi-stable pixel states and thus facilitates passive matrix addressing. For this purpose an additional electrode (1305) is arranged for each multi-stable state. Consequently, each pixel comprises one counter electrode (1306) and at least one pair of address and retain electrodes (1304, 1305). In order to activate a pixel, an address potential is applied to the address and retain electrodes (1304, 1305) in relation to the counter electrode (1306), and in order to deactivate a pixel the potential is removed. In order to retain a current pixel state a retain potential is applied to only the retain electrode (1305) in relation to the counter electrode (1306); the current pixel state, be it active or passive, will then be preserved and the retain potential configuration thus provides a bistable pixel state.
