ARRANGEMENT FOR A VEHICLE LAMP

Abstract

An arrangement is provided for a vehicle lamp having a flexible printed circuit board, a means of reinforcement of one area of the flexible printed circuit board that is connected to the flexible printed circuit board, an LED that is arranged in this area on the printed circuit board, and a means of shaping light that can be emitted by the LED. The means of shaping light includes at least one light-shaping optical means, and the means of reinforcement is connected to the means of shaping light. The means of reinforcement includes at least one protruding element that comes into contact under tension with a connecting element of the means of shaping light or with a connecting element connected to such means and/or engages an indentation of the connecting element.

Claims

1. An arrangement for a vehicle lamp, the arrangement comprising: a flexible printed circuit board, a means of reinforcement of one area of the flexible printed circuit board, the means being connected to the flexible printed circuit board, at least one LED arranged in the area on the printed circuit board, and a means of shaping light emitted by the LED, said means of shaping light including at least one light-shaping optical means, wherein the means of reinforcement is connected to the means of shaping light, the means of reinforcement including at least one protruding element that comes into contact under tension with a connecting element of the means of shaping light or with a connecting element connected to such means and/or engages an indentation of the connecting element.

2. The arrangement in accordance with claim 1, wherein the protruding element is elastic or has an elastic connection with the other means of reinforcement.

3. The arrangement in accordance with claim 1, wherein the reinforcing means includes more than one protruding element.

4. The arrangement in accordance with claim 3, wherein the at least one protruding element is aligned to a direction opposite to a movement for disconnecting the connection between the reinforcing means and the connecting element.

5. The arrangement in accordance with claim 1, wherein the at least one protruding element is a stamping.

6. The arrangement in accordance with claim 3, wherein the connecting element features at least one indentation.

7. The arrangement in accordance with claim 1, wherein the connecting element includes several neighboring indentations.

8. The arrangement in accordance with claim 1, wherein the at least one indentation of the connecting element features an undercut aperture and that the at least one protruding element engages the undercut.

9. The arrangement in accordance with claim 1, wherein the connecting element features panels opposite each other, between which a holder is formed which accommodates at least part of the reinforcing means.

10. The arrangement in accordance with claim 9, wherein the reinforcing means is clamped between the panels.

11. The arrangement in accordance with claim 9, wherein the protruding element of the reinforcing means engages in the indentations of the connecting element, where the indentations are provided for on the opposite panels.

DETAILED DESCRIPTION OF THE DRAWINGS

[0028] The reinforcing means 1 shown in FIGS. 1 through 7 is a piece of sheet metal bent to be U-shaped with two legs 11 and a bar connecting the legs 12. Holes 14 are provided for in the bar 11 at corners diagonally opposite each other, into which holes structures intended for positioning the printed circuit board towards the reinforcing means or other components, for example mandrels, can be inserted.

[0029] At four places in a transitional area between the bar 11 and the legs 12, tongues 13 in pairs opposite each other are shown as protruding elements. The ends of these tongues 13 extend laterally beyond the legs 12. The tongues 12 can be manufactured by means of punching and bending. The protruding elements 12 can be elastically deformed when little force is applied.

[0030] The means of shaping light features three connecting elements 21, 22 that are shown in FIGS. 5 through 7. These are permanently connected to further areas of the means of shaping light. These further areas are not shown in the Figures. Two connecting elements 21 of the three connecting elements 21, 22 are located at one side of the means 1 of reinforcement. The third connecting element 2 is located on the opposite side. The connecting elements 21 on the one hand and the connecting element 22 on the other hand panels facing each other that form a holder of the means of shaping light into which the means 1 of reinforcement and a flexible printed circuit board fastened in particular to its bar 11 can be arranged. The distance between the panels of the connecting elements 21, 22 is larger than the outer distance of the legs 11 of the means 1 of reinforcement and smaller than the distance between the outer ends of the protruding elements 13.

[0031] The means of reinforcement 1 can, as shown in FIGS. 5 through 7, be arranged in the holder between the connecting elements 21, 22. In this context, the protruding elements 13 are elastically bent with little force such that they come into contact with the panels of the connecting elements 21, 22 by means of a friction connection, bringing about a connection between the flexible printed circuit board and the means of reinforcement on the one hand and the means of shaping light on the other.

[0032] The variant of the means of reinforcement 1 shown in FIG. 8 differs from the means 1 shown in FIGS. 1 through 7 in that it is not U-shaped and consequently does not feature any legs 12. The variant does however feature the tongues 13 or the protruding elements 13 intended for the connection between the means of shaping light and the means of reinforcement which project laterally beyond the bar 11. With these protruding elements 13, it is possible for the variant to be connected to a means of shaping light just as with the means of reinforcement 1 shown in FIGS. 1 through 7.
