Abstract: According to the present disclosure, a concrete casting system including a large number of individual concrete casting boxes is provided. The concrete casting system has a grid-like structure in which the individual concrete casting boxes are arranged at the intersection points of the grid-like structure. Two respectively adjacent concrete casting boxes are connected to one another by means of a spacer. Each concrete casting box has a housing which has at least one opening in a direction perpendicular to the direction of extent of the grid-like structure. The concrete casting system is designed such that it can be rolled up or folded.

Abstract: A lamp includes a tubular glass bulb with open end sides, at least one elongate carrier, inserted into the glass bulb, for at least one light strip, at least one elastic diffuser layer which is introduced into the glass bulb, and two bases which are fitted onto the open end sides of the glass bulb. The at least one light strip has a strip-shaped circuit board with a front-side conduction structure and with at least one semiconductor light source which is electrically connected thereto. The conduction structure is electrically connected to at least one of the bases. The at least one diffuser layer arches over the at least one semiconductor light source and the at least one conduction structure in a contact-free fashion at least over a length between the bases. The at least one diffuser layer is latched to the at least one carrier.

Abstract: An elongate light source (1) having at least one elongate lamp (3) with two ends, which has a light-guiding element (2; 4; 5) at at least one end.

Abstract: An operating method, in particular a dimming method for a discharge lamp. In order to set the maximum brightness, two outer electrodes (5,6), for example, are used to generate in the discharge lamp a dielectrically impeded discharge which, through the formation of xenon excimers, emits UV radiation which is converted into light with the aid of fluorescent materials (2). In order to permit intense dimming of the discharge lamp, two cold cathodes (3, 4) are used to generate a xenon low-pressure discharge emitting UV beams, and the dielectrically impeded discharge is switched off. Both types of discharge are preferably excited by high-voltage pulses which are generated by an operating unit (7). Dimming is preferably performed by blanking pulse trains.

Abstract: The invention relates to a lighting apparatus having a translucent, light-diffusing panel (1), with at least one aperture lamp (2,3) arranged along one edge, extending in a straight line, of the light-diffusing panel (1) and mounted to rotate about its cylindrical axis in a mounting (6,7) and having a screen (4,5) for the at least one aperture lamp (2,3). By rotating the at least one aperture lamp (2,3) about its axis, the light input into the translucent, light-diffusing panel (1) is influenced.
