Parallel to the base 16 extends from the shorter leg 14 a tab 18 path. At the bottom of the tab 18 are in longitudinal extension, parallel to the U-shaped profile extending grooves 20 intended. On the top of the tab 18 and the base 16 are ripples 22 provided, which in this embodiment also a groove-like depression 21 leave free, and also extend parallel to the longitudinal direction of the profile.

The distance S between the legs 12 . 14 of the U-shaped profile corresponds approximately to the diameter D of an LED tube 26 as he is in 2 is shown. Typical dimensions of the lighting fixture 10 are as follows. The length of the longer thigh 12 For example, it may be 1.5 cm and the length of the shorter leg 0.8 cm. For example, while the spacing of the two legs may be 1.2 mm, the extent A of the lighting fixture may be 10 be perpendicular to its longitudinal extent, for example, 5 cm, this measure of the sum of the depth T of the tab 18 (ie the extent perpendicular to the longitudinal extent of the U-shaped profile) and the width of the base 16 corresponds to the U-shaped profile. In particular, the depth of the tab 18 However, it can also be adapted to the particular requirements of the specific application, as explained below by way of example for a step.

The LED tube 26 , which in the embodiment shown has circular cross section, comprises a series of light emitting diodes (LEDs) 28 on, at regular intervals along the LED tube 26 are arranged and over supply lines 34 be supplied with electrical power. The LEDs 28 and the supply lines 34 are molded in plastic, so that a circular cross-section results in a diameter D. Due to the use of plastic, the entire assembly is very flexible and can be adapted to different shapes by appropriate bending of the hose 26 be adjusted.

In 4a Such a geometry is shown in the cross section of the stairs. The LED tube 26 is essentially according to the arrangement of 1b used. By illuminating the faces 42 the stairs 36 Ensures that the steps are clearly visible and accidents in the dark can be effectively prevented. Of course, the lighting can also be used for aesthetic purposes.

4b shows an arrangement in which in particular the tread 40 a stage 36 is illuminated. This is the LED tube 26 such in the lighting fixture 10 used as it is in 1a is shown.

In both cases it becomes clear that an optimal lighting of the step is possible without blinding a user. When using the lighting fixture according to the invention on a step, as for example in the 4a and 4b is shown, it also proves to be advantageous if on the upper side parallel to the longitudinal extension of the lighting fixture 10 Riffel 22 extend, which can serve as a sliding brake on the step.

In the in 4c embodiment shown has the tab 18 such a depth T that they cover the entire tread 40 covers and insofar even represents a tread. An embodiment according to 4d Provides that in the front area of the tread 40 a paragraph 41 is provided, one of the tab 18 corresponding height and depth T has. The tab 18 then lies in the paragraph 41 so that the tread 40 the stage 36 is just. In 4c and 4d is the lighting area 32 not specified, but can, for example, as in the 4a or 4b be set.

In 5 an embodiment is shown in which light can escape not only through the open side of the U-shaped profile, but also by additionally provided light exit openings 44 that go along the base 16 of the U-shaped profile are arranged. In this way, not only the already described illumination of the face 42 the stage 36 or the tread 40 the stage 36 possible, but also an additional lighting, which points upwards. This is to increase safety or may be used for aesthetic purposes.

For this purpose, in this embodiment, for example, an adhesive strip in the groove 21 on the top of the tab 18 intended. Of course, another type of attachment can be selected. In cross-section of 6 It is clear that with the illumination arrangement according to the invention, the entire work surface on a kitchen cabinet 48 can be illuminated, especially because of the one leg 14 of the U-shaped profile is shorter than the diameter D of the LED tube 26 , Because the other leg 12 the U-shaped profile is longer than the diameter of the LED tube, on the other hand, a glare of a person in front of the kitchen cabinets, however, avoided.

7a shows how a lighting fixture according to the invention 10 on a board 50 with adhesive tape 38 can be glued. This is particularly advantageous if, for example, a shelf is to be illuminated, as in 7b is visible. A thing 52 which is located on the shelf is, with the illumination arrangement according to the invention mainly on the illumination area 32 illuminated when the lighting fixture holder 10 on the shelf 50 is attached. Alternatively, the lighting fixture holder 10 also be mounted below the shelf, as for example in the case of the kitchen top cabinet 46 in 6 is shown. Deviating from the arrangement of 7b can the lighting fixture holder 10 Finally, from the bottom of a shelf 50 glued or fastened to a shelf above the with the fixture holder 10 provided shelf 50 to illuminate.

Even in the applications described with shelves and cabinets and other applications, the lighting fixture holder, in particular the tab 18 , have such dimensions that the mounting surface, so for example, the shelf surface or the kitchen cupboard underside, is completely covered. Likewise, a shoulder for receiving the tab may be provided on the attachment surface, as explained above the example of a step.

8th shows another embodiment in which no LED tube 26 is used, but a so-called LED neon element 54 , This consists essentially of an opaque plastic part of the illustrated cross section, in which LEDs are also cast. Here is a direct dazzling lighting due to the opaque plastic is not possible, the only diffuse lighting passes. The lighting fixture holder 10 can also be used, and such a LED neon element 54 to keep it stuck.

In the present description, various examples of the advantageous application of a lighting arrangement according to the invention are described. Of course, the individual embodiments and applications can also be used together or in other combinations. For example, it is possible that even when using a lighting arrangement according to the invention in the illumination of shelves, as with reference to 7a and 7b is explained, lighting fixture 10 with additional light emission openings 44 be used.
