    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: The invention relates to a backlighting system (10, 11, 12, 13, 14, 15, 16) and to a display device. The backlighting system comprises a plurality of segments (20, 21, 22, 23, 24) for selectively illuminating a predefined area of pixels of a display device. The backlighting system is configured for selectively controlling the intensity and/or color of the light emitted from the segment, each segment comprising a light source (30). The backlighting system (10, 11, 12, 13, 14, 15, 16) further comprises light barriers (40) for limiting the lateralspreading of the light emitted by the light source (30) towards the neighboring segments (20, 21, 22, 23, 24). The light barriers define grid-lines of a grid, and the light source (30) is arranged at a position on the grid-line which at least partially coincides with at least one of the light barriers. The effect of the measures according to the invention is that by positioning the light source of the segment on the same grid-line as the light barriers, the light from the light source spreads on either side of the light barrier towards the neighboring segments. This enables a predefined overlap of the light emitted by the segment towards its neighboring segments without the need for additional thickness of the backlighting system.

    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.
