    • The invention relates to a collimation arrangement (1, 2, 3, 4) for collimating light emitted by at least one light emitting diode (12, 14) arranged on a planar base (16). The collimation arrangement (1, 2, 3, 4) comprising a collimator (20, 22, 24) and a set of reflective surfaces (50, 52). The collimator comprises a light-ingress window (28, 30) for admitting light emitted by the at least one light emitting diode into the collimator (20, 22, 24), a light-egress window (32, 34) for emitting the light from the collimator (20, 22, 24), and comprises a first edge surface (36), a second edge surface (38), a third edge surface (40, 42, 44) and a fourth edge surface (46, 48). The collimation arrangement (1, 2, 3, 4) is arranged for guiding light emitted by the at least one light emitting diode (12, 14) in a direction of the third and fourth edge surfaces (40, 42, 44, 46, 48) towards the light-egress window (32) via total internal reflection and is arranged for guiding light emitted by the at least one light emitting diode (12, 14) in the direction of the first and second edge surfaces (36, 38) via the reflective surfaces (50, 52). This results in a collimation arrangement of which the width (w) can be easily reduced.

    • A variable reflector device, comprising a reflector (6) arranged to direct light from a light source (7) and a casing (5) containing the reflector (6), a portion of said casing (5) being transparent to light directed by the reflector (6). The reflector (6) is formed by a meniscus (2) at an interface between two immiscible fluids (3,4) contained in said casing (5). According to this design, the spatial distribution of light from the light source is changeable by changing the shape of the meniscus between the two fluids. Since a change in shape of the meniscus is effected by a displacement of fluids rather than of mechanical parts, the change in reflector shape can generally be performed faster and with less energy consumption than is the case with previously known designs. Further, a meniscus between two immiscible fluids can, due to the nature of fluids, take on several different shapes, which is not the case when a solid body reflector is utilised.
    • 一种可变反射器装置,包括布置成引导来自光源(7)的光的反射器(6)和包含反射器(6)的壳体(5),所述壳体(5)的一部分对于由 反射器(6)。 反射器(6)由弯液面(2)在容纳在所述壳体(5)中的两个不混溶流体(3,4)之间的界面处形成。 根据该设计,通过改变两种流体之间的弯液面的形状,可以改变来自光源的光的空间分布。 由于弯液面的形状变化是通过流体而不是机械部件的位移来实现的,反射器形状的改变通常可以比先前已知的设计更快地实现更少的能量消耗。 此外,两种不混溶流体之间的弯液面可以由于流体的性质而承受几种不同的形状,这在使用固体反射体时不是这种情况。
