Light-guiding building installation device for a building, building installation arrangement for a building, and corresponding building

Abstract

Light-guiding building installation device (1) for a building (1), for an arrangement on the building (1) that at least partially penetrates a building boundary (2) of the building (1), with opposing and angled and / or curved light reflectors (22, 23) which together define a light-guiding space (24) extending from a translucent sealed light inlet opening (25) to a translucent sealed light outlet opening (26), with a light absorption device comprising a first light absorption device for absorbing light in the infrared range with a non-variable absorption coefficient and a second light absorption device for absorbing visible light, the absorption coefficient of which is adjustable, wherein the first light absorption device is directed onto at least one of the light reflectors (22,23) applied absorption layer (29) and the second light absorption device is a switching device (30) located in a light guidance path extending from the light inlet aperture (25) to the light outlet aperture (26), which in a first switching position has a first light transmittance and in a second switching position has a second light transmittance different from the first light transmittance, and wherein the switching device (30) has a light-transmitting disk (31) extending from one of the light reflectors (22, 23) to the other of the light reflectors (22, 23), which divides the light guidance space (24) into several light guidance subspaces (33, 34, 35).
