Abstract: A light fixture for illuminating building surfaces or partial surfaces of a building has a housing, a light source on the housing, a focusing optical unit on the housing and separate from the light source for focusing and projecting light emitted by the light source in a direction, a first lens plate in the light path spaced a first distance downstream in the direction of the focusing optical unit, the first lens plate having a plurality of first lenticular lenses arranged thereon, a second lens plate receiving light from the first lens plate and spaced a second distance downstream in the direction from the first lens plate, the second lens plate having a plurality of second lenticular lenses arranged thereon. Each of at least some of the first lenticular lenses is aligned in the direction with a respective second lenticular lens.

Abstract: The invention relates, inter alia, to a light fixture (10) for illuminating building surfaces (17) or partial surfaces of a building, comprising a housing (11), at least one light source, in particular an LED (12, 12a, 12b, 12c) and at least one collimator optical unit (15, 15a, 15b, 15c) for focusing the light emitted by the light source. The particularity of the invention, inter alia, is that in the light path downstream of the collimator optical unit at least two lens plates (18, 19) are provided, on both of which a plurality of lens elements (22a, 22b, 22c, 23a, 23b, 23c) being arranged, in particular grouped, thereon, wherein the spacing (32) between the two lens plates is variable by an adjusting device (20), and wherein the light fixture provides different light distributions (37, 38, 39, 50a, 50b, 50c) in different spacings of the lens plates.

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.

Abstract: The invention shows and describes, among others, a light fixture (10) for illuminating building surfaces, comprising a circuit board (11) on which a plurality of LEDs (12a, 12b, 12c) are mounted, secondary optics (14) that bundle the light emitted by the LEDs, and tertiary optics (16) formed by a planar, translucent element that has light-directing microstructures.

Abstract: A lighting control system has at least one light fixture for illuminating buildings or partial surfaces thereof or goods or objects. Each light fixture has a plurality of light sources that generate light of different colors, and each fixture produces a total light output as a sum or mixture of the light emissions of these light sources. The control system itself has at least one control for adjusting the light emitted by the light source, a color selector that sets the color of the total light output, and a balancer that retains a set color of the total light output when a light output of at least one of the light sources is changed.
