The invention relates to a luminaire that enables the use of more sparsely distributed light sources, having a uniform fixture surface brightness and good color mixing. The luminaire comprises first and second light guide layers (10, 11) optically coupled together by at least one optical coupler (12a, 12b), which allows the passage of light from the first (10) to the second light guide layer (11). The luminaire also comprises a plurality of light sources (16a, 16b), each of which being arranged such that light emitted by the light source (16a, 16b) is coupled into the first light guide layer (10) at an interface surface (17)arranged substantially perpendicularly to a longitudinal axis of the first light guide layer (10). The luminaire further comprises a scattering element (14) adapted to cause light to be emitted from an emitting surface of the second light guide layer (11). By providing two optically coupled light guide layers (10, 11), one for receiving light emitted by the light sources (16a, 16b) and the other for emission, greater opportunity for dispersion and color mixing of the light is provided.

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 1D arranged first prisms having first prism axes, and a second layer having a second prismatically shaped top face with a plurality of 1D arranged second prisms having second prism axes. The first and second prism axes are in a crossed configuration. In a direction from the first collimator face to the second collimator face, the index of refraction of material upstream of the first prismatically shaped top face is larger than that of material downstream of the first prismatically shaped top face, and the index of refraction of material upstream of the second prismatically shaped top face is larger than that of material downstream of the second prismatically shaped top face.

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.

The illumination system has an array of light sources (1, 1′, . . . ) such as an array of light emitting diodes arranged in a pre-determined manner in a first plane (11), wherein dsource is a characteristic dimension of the spatial arrangement of the light sources in the first plane. An array of associated lenses (2, 2′, . . . ) is arranged in substantially the same pre-determined manner in a second plane (12). Each lens has substantially the same focal distance flens. The array of lenses is provided at a plane distance dplane from the array of light sources. The plane distance dplane is substantially equal to the focal distance flens of the lenses. The illumination system has displacement means for displacing the array of lenses with respect to the array of light sources so as to obtain a plurality of directional light beams projecting spots on a projection plane arranged at a projection distance dprojection from the illumination system, wherein dprojection≧10×dsource and dprojection≧10×dplane.
