Abstract: The invention relates to a fire-resistant component (1) which satisfies the requirements of at least class B-15. Such components are known per se and are manufactured as insulated steel structures. In order that the component (1) can be manufactured more easily and with greater versatility in the manner of glass-fiber-reinforced plastic, it is proposed that it is manufactured with multiple layers of phosphate ceramic and also of fibers (7, 8, 9), and that a layer structure of the component (1) comprises at least one layer (4), on the surface thereof which faces towards a potential heat source, which is joined together only partially with a layer (5) arranged thereunder, i.e. remote from the heat source. The invention also relates to a process for producing such a component.

Abstract: The invention relates to a light (1) especially a wall or ceiling light protected from spray water and used to receive at least one long gas discharge lamp (5), said light comprising a closed housing formed by an at least transparent base part (3) which can be mounted in a fixed location and holds electrical devices, and an at least transparent coupling part (2). The base part (3) and the coupling part (2) are injection-molded from the same charges of thermoplastic material in a common mold which is essentially symmetrical in terms of the injection process, and overlap along peripheral edges on both sides, one edge being an insertion edge (10) and the other edge being embodied as a U-shaped receiving element (9) for receiving the insertion edge (10).

Abstract: A luminaire, in particular a wall or ceiling luminaire protected against sprayed or splashed water, for receiving at least one elongated gas-discharge lamp, having an enclosure able to be assembled into a closed form from a transparent lower part which can be mounted in a fixed position and which holds electrical gear and a transparent upper part, is so designed, with the aim of achieving a form for the upper part and lower part which is economical and meets the demands of the market and in which the two are matched to one another in relation to thermal stresses, that the lower part and the upper part are produced from the same batches of thermoplastic plastics material.
