    摘要: Proposed is a luminaire (1), comprising light sources (10) and optical elements (20). The light sources (10) are arranged in a first (11) and a second array (12), while the optical elements (20) are arranged in a first (21) and a second section (22). The first ‘light sources’ array (11) and the first Optical element’ section (21) form a first group (31), and the second array (12) and the section (22) form a second group (32). The luminaire (1) is characterized in that the optical elements (20) of each group are arranged to have different beam shaping characteristics, and the arrays (11,12) are arranged to be individually addressable. This is especially advantageous in illumination applications where the control of the beam shape is required or desired. Advantageously, the invention provides a luminaire (1) capable of adjusting the beam shape without using an adjustable optical system. Moreover, the control bandwidth of the light sources limits the speed with which the beam shape can be adjusted.

    摘要: An autostereoscopic display device uses a converged backlight output, and the convergence is performed with a light converging arrangements (60,62) which preferentially converge light inwardly along a certain axis perpendicular to the elongate axis of the lenticular elements (11). This means that the amount of light directed at large angles sideways between the lenticular elements (11) is reduced to a minimum. This reduces the amount of light tunneling within the lenticular array and therefore improves the display output, in particular the brightness and contrast.

    摘要: A display device is provided with a display screen (30) for displaying image information, having a predetermined number of luminescent picture elements (35). In operation, an electron beam (45) is generated by an electron gun (40) and entered into a two-dimensional slalom guide (10), wherein the beam is guided in two mutually perpendicular directions by means of slalom focusing. Subsequently, the electron beam (45) is extracted from a selected cell (56) of the slalom guide (10) towards a corresponding picture element (35). The path of the electron beam (45) in the slalom guide (10) can be fully customized within the guidance plane. Preferably, the guidance plane extends substantially parallel to the display screen (30).
