[origin: CN111351006A] The invention relates, inter alia, to a light fixture (10) for illuminating building surfaces (17) or partial building surfaces, comprising a housing (11), at least one light source, in particular anLED (12, 12a, 12b, 12c), and at least one collimating optics, in particular collimating optics (15, 15a, 15b, 15c) for collimating the light emitted by the light source. A particular feature is that at least three lens plates (18, 19) are provided in the light path behind the collimating optics, on each of which lens plates a plurality of lens elements (22a, 22b, 22c, 23a, 23b, 23c, 69a, 69b, 69c,70a, 70b, 70c) is arranged, in particular grouped, wherein the relative spacings (32, 75) between one of the two outer lens plates, in each case, and the central lens plate, can be changed by means of at least one adjustment device (20), and wherein the light fixture provides different light distributions (37, 38, 39, 50a, 50b, 50c) in different mutual spacing positions of the lens plates.
