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:
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:
Various embodiments may relate to a device for the surface treatment of a substrate, including a processing head, which is mounted rotatably about an axis of rotation, and which comprises multiple gas outlets, which are at least partially implemented on a radial outer edge of the processing head.
