Abstract

The invention is related to a method for assembly a turn signal indicator module mounted into a rear view mirror comprising a housing. A LED, a light guide and a lens of the turn signal indicator module are mounted in steps as:

Mounting the LED on a printed circuit board, fixing the printed circuit board at the light guide to define a strict relation between the LED and the light guide and mounting the light guide, the lens and the housing to form a turn signal indicator module.

Claims

1. Method for assembly a turn signal indicator module mounted into a rear view mirror comprising a housing, at least one LED and at least one light guide and a lens that covers the turn signal indicator module wherein the following steps are realized:

mounting the at least one LED on a printed circuit board;

fixing the printed circuit board at the light guide to define a strict relation between the at least one LED and the end face of the light guide using connection means;

mounting the light guide, the lens and the housing to form a turn signal indicator module, wherein the at least one LED and the end face of the light guide are connected by protrusive connection means.

2. Method for assembly a turn signal indicator module according claim 1, characterized in that the mounting steps are realized in the order of:

a) Mounting the at least one LED on a printed circuit board

b) Fixing the printed circuit board at the light guide to define a strict relation between the at least one LED and the end face of the light guide using connection means

c) Mounting the light guide, the lens and the housing to form a turn signal indicator module.

3. Method according claim 1 characterized in that the light guide and the printed circuit board are connected by a clips mechanism.

4. Method according claim 1 characterized in that the light guide and the printed circuit board are connected by gluing.

5. Method according claim 1 characterized in that the light guide and the printed circuit board are connected by hot-riveting.

6. Method according claim 1 characterized in that the light guide and the printed circuit board are connected by welding.

7. Light guide sub module to be mounted into a rear view mirror comprising a housing, at least one LED and at least one light guide and a lens that covers the turn signal indicator module wherein the following steps are realized:

mounting the at least one LED on a printed circuit board;

fixing the printed circuit board at the light guide to define a strict relation between the at least one LED and the end face of the light guide using connection means;

mounting the light guide, the lens and the housing to form a turn signal indicator module, characterized in that the at least one LED and the end face of the light guide are connected by protrusive connection means; and

wherein the light guide forms projections adapted to lead the light guide in the printed circuit board by leading means and fix it.

8. Light guide sub module according claim 7 characterized in that the projections of the light guide forms hooks for a snap-fit connection to the circuit board.

9. Light guide sub module according claim 7 characterized in that the light guide forms gluing faces to be glued to bumps of the printed circuit board.

10. Light guide sub module according claim 7 characterized in that the light guide forms welding faces to be welded to bumps of the printed circuit board.
