Description of the invention

The subject of the invention is a lighting module designed to create lighting strips both outside and inside buildings.

From US 5,130,909, an emergency lighting strip is known to be placed along the floor to indicate an escape route in public buildings. The strip is in the form of a strip with spaced LED elements covered with a protective light transmitting cover.

The Polish patent specification PL 184066 describes a flexible electrically conductive element for indicator light devices, consisting of an elongated flat electrically conductive part made with the technique of printed circuits, on which electronic components with LED diodes are attached. The flexible conductive element is covered with a ribbon of colored foil surrounding the electronic components and is suitable for installation in a vinyl floor.

From the Polish patent application P.369255, a lighting fixture is known to be used as illumination from the internal surfaces of transparent or translucent materials, especially glass shelves in shelves or glass tops of tables and desks. The mount has an inner ring provided on both sides with lids with an outer diameter greater than the outer diameter of the ring, and at least one source, preferably in the form of an LED, is provided on the outer side of the inner ring.

From the Polish application for a utility model no. 115764, a lighting fixture is known for illuminating objects, furniture or rooms inside a building. The cylinder-shaped body made of plastic with an edge cut at one end has two holes on the mounting surface for mounting the luminaire. A hole is cut from the front side, in which a light source is mounted, in the form of a set of semiconductor light diodes soldered on a circular-shaped printed circuit board and mounted in a transparent plastic cover. A lighting fixture according to the Polish application for utility model No. 115765 has a similar structure, differing in the rectangular shape of the printed circuit board.

The disadvantage of the known solutions is their complicated structure, high labor consumption associated with their assembly in the destination places, replacement of damaged elements of the composition and high installation costs.

The lighting module according to the invention comprises a fixing profile with a cross section similar to the letter "U" with arcuate arms flared outwards at the ends, in which is situated a fixture containing a printed circuit board with LED diodes. The fitting is composed of two parallel, longitudinally cut and connected with each other along the entire length by the edges of the pipes. The pipe protruding beyond the fixing profile has an annular cross-section, and the second pipe fixed in the profile has a rectangular cross-section with two opposing arched walls connected by its bottom. The inner surfaces of these walls are equipped with longitudinal channels in which the printed LED plate is located. The bottom of the housing rests on longitudinal projections made on the inner surfaces of the legs of the mounting profile.

Both ends of the tubular fixture are closed with plugs protecting its interior. At the ends of the housing, there are cutouts at the bottom of the housing, in which there are gaskets with openings for power cables.

The advantage of the solution is the simplicity of construction, easy installation of modules on the facilities intended for this purpose, low installation and operating costs while maintaining resistance to weather conditions and ensuring safe use. The thin wall of the luminaire provides effective light transmission, the color of which depends on the color of the luminaire material.

The subject of the invention is shown in the embodiment in the drawing, in which Fig. 1 shows a lighting module in cross-section, and Fig. 2 shows the module in longitudinal section.

The lighting module consists of two separate parts: the fixture 1 and the mounting profile 2. The fixture 1 consists of two parallel pipes 3, 4 cut longitudinally and connected with each other along their entire length by edges. The tube 3 made of a material transmitting light has an annular cross-section, while the tube 4 has a cross-section similar to a rectangle with two opposing walls 6 connected by a bottom 5 arched arched. The walls 6 of the fixture 1 on the inner surfaces are provided with longitudinal channels 7, in which the edges of the printed circuit board 8 are located with LEDs 9 arranged along the board 8 every 20 mm. The tube 4 of the fixture 1 is situated in the fixing profile 2 with a cross-section similar to the letter "U" with the arcuate arms 10 flared at the ends 11 outwards. The inner surfaces of the arms 10 are provided with

There are longitudinal projections 12 on which the bottom 5 of the housing 1 rests. To the ends of the housing 1, plugs 13 are glued tightly closing the interior of the housing 1. At the ends of the housing 1 in its bottom 5 there are cut-outs in which gaskets 14 are placed. holes for the power wires 15 connected to the printed circuit board. One pair of wires 15 terminated with a plug 16 is used to power the LEDs, the second pair of wires 15 terminated with a socket 17 is used to connect with a plug 16 of the next module.

In another solution, instead of connecting modules with sockets and plugs, it is possible to solder the ends of the wires and protect the connection with heat-shrinkable sleeves.

The ends of the module can be straight or cut at any angle, which allows them to be arranged in ribbons of any shape. The profiles are attached to the wall, floor or shelf, and then the fittings are pressed into them, placing the cables in the bottom part of the profile.
