Abstract: The invention relates to a lamp operating device (10) for operating one or multiple light sources (20-1, 20-2), with a first interface unit (15) for connecting the lamp operating device (10) to a control line (2) and for receiving external control commands corresponding to a first communications protocol, and with a control unit (11) which operates the light source(s) (20-1, 20-2) in accordance with the control commands received via the first interface unit (15). A second interface unit (17) is provided for receiving programming information according to a second communications protocol, wherein the conversion of the control commands received via the first interface unit (15) for operating the light source(s) (20-1, 20-2) is performed by the control unit (11), at least partially taking into account the programming information.

Abstract: The invention relates to a device and a method for controlling the light emission (i) of at least three light sources (21, 22, 23), wherein the light emitted by the light sources (21, 22, 23) is detected in a sequence of measuring periods during a calibration phase, and calculated on the basis of the information on the brightness of each individual light source (21, 22, 23) obtained during the measuring periods. In at least one of the measuring periods, the detected light comes from a plurality of the light sources (21, 22, 23).

Abstract: The invention relates to a light comprising a light source or connection means for a light source, and a transparent panel which extends crosswise to a direction of light emission. An object of the invention is to improve the light in terms of glare suppression. To this end, the transparent panel is provided with a microstructure and light homogenization means are provided. The latter ensure that the brightness of the light entering the panel is approximately equal in all parts of the panel.

Abstract: There is proposed a luminaire (10) with which the exit angle of the light beams is restricted for the purpose of anti-dazzling. Further, in accordance with the invention there is attained in a simple manner and in particular without the employment of a light guide element a uniform emission of light over the entire surface of an optical element (14; 14-1, 14-2) arranged before or in the emission opening (13) of the luminaire (10). The optical element (14; 14-1, 14-2) has a plate-like core (16) of transparent material, which is occupied on one side with microprisms (17) which, with the formation of furrows (18)—starting from their roots—taper.

Abstract: An optical element (10, 10′, 10″) for deflecting light beams (18, 19), which enter and re-emerge from the latter, in such a way that their angle of emergence (&ggr;) is limited, in particular for use as a luminaire-cover, having a plate-like core (11, 11′, 11″) of transparent material which on one side is occupied by microprisms (12, 13) that taper—starting from their root (15)—forming furrows (22), wherein all of the top surfaces (14) of the microprisms form the light-entry face and the other side (21) of the core forms the light-emergence face, and wherein the top surfaces (14) of the microprisms are formed convexly or concavely in a continuous or non-continuous manner, and also a method for producing the optical element (10, 10′, 10″).

Abstract: Illumination arrangement (2), profiled bodies (5) of a light permeable material being formed in a base body (4), which profiled bodies are spaced apart from one another by means of recesses (6). To each profiled body there is applied a luminous means (7) which emits light into the corresponding profiled body. The light is directed internally by the profiled body (5) to an emission surface of the base body (4) in such a manner that it emerges there within a maximum emission angle range, to avoid dazzling an observer. As luminous means (7) a flat fluorescent lamp can in particular be employed.

Abstract: An optical element for deflecting light beams is formed form a plate-like core or element 1 of transparent material having tapered microprisms 2 one side, with furrows 7 formed between the microprisms, the furrows being covered with a reflective layer 12, and a foil 11 of transparent material arranged on a side of the reflective layer remote from the core or element 1.
