Abstract: A modular illuminating device comprises at least one frame (1) with the front elastic catches (2) for securing a transparent cover (4) to the frame (1), and the rear elastic catches (3) for fixing the frame (1) to a printed-circuit board (5) with at least one printed circuit module (6) and at least one light-emitting diode module (7) on its front side. The printed-circuit board (5) has multiple equally spaced assemblies comprised of the printed circuit modules (6) and LED modules (7), arranged in a row, or a rectangular matrix, or a honeycomb structure. The power line is printed along the printed-circuit board (5) with offtakes to individual printed circuit modules (6) and LEDs modules (7). Alternatively, the printed power line supplies the AC/DC converter placed at one end of the printed-circuit board (5), and the AC/DC converter supplies individual printed circuit modules (6) and LEDs modules (7) with constant voltage via another pair of leads printed along the printed-circuit board (5).

Abstract: The object of the invention is the lighting fitting using LED-based source of C light, applied for constructing functional frames, backlighting stair treads and stair risers, furniture shelves, backlighting current connectors and lighting traffic routes in buildings and structures. The lighting fitting is supplied by an electrical system and it has a casing (1) with one side open with a source of light (2) placed inside it. On the side of the casing (1) opening, there is an optical fibre element (4) in the form of a shaped plate whose at least two edges (3) and (7) transmit the luminous flux, with one on the side of the light source (2), similarly as the front wall (5) of the optical fibre element (4), while the back wall (6) of the optical fibre element (4) is partly or wholly matted or covered with a light reflecting material or fluorescent material.

Abstract: The object of the invention is a lighting clip used as backlighting of transparent or semi-transparent materials in the form of glass or plastic panes, in particular, glass shelves in a display cabinet or glass desk and table tops. The lighting clip fixed around an edge of a transparent or semi-transparent panel in a removable or permanent way and supplied by an electric power system, characterised by the fact that it is in the form of a section (1), with at least one side open, built of clamping arms (2) and (3) joined with a connector (4) and equipped with at least one source of light (6) placed in the internal space (5).
