Claim 10:
11. A method for assembling a lighting device (10), comprising the following steps in chronological order:
a) providing
at least one light source (50),
a light guide (200) comprising an end section (210) with a light entry surface, wherein the light guide (200) is assigned to the at least one light source (50) for guiding light which is emitted by the at least one light source (50) and coupled into the light guide (200) at the light entry surface,
a light guide adapter (300) configured to secure the end section (210) of the light guide (200) and to hold the light entry surface in a final target position with regard to a support frame (400), the light guide adapter (300) comprises a base-section (310) and a securing-section (320), wherein the securing-section (320) of the light guide adapter (300) comprises at least one first engaging-element (320a), the base-section (310) comprises at least one first fastening-opening (311), and
a support frame (400), on which the light guide adapter (300) is mounted, wherein the support frame (400) comprises a mounting-opening (410) for the securing-section (320) and a support frame fastening-opening (411), wherein the mounting-opening (410) has at least one support frame engaging-element (410a) corresponding to the at least one first engaging-element (320a) of the securing-section (320);

b) positioning the light guide (200) in the final target position with regard to the support frame (400);
c) inserting the light guide adapter (300) into the mounting opening (410);
d) bringing the light guide adapter (300) into an end position (P2), such that the at least one first engaging-element (320a) engages with the at least one support frame engaging-element (410a), wherein the at least one first fastening-opening (311) and the support frame fastening-opening (411) are overlapped, so that the at least one first fastening-opening (311) and the support frame fastening-opening (411) receives a fastening-element (110), wherein the light guide adapter (300) secure the end section (210) of the light guide (200) in the final target position; and
e) inserting the fastening-element (110) into the at least one first fastening-opening (311) and the support frame fastening-opening (411), wherein the at least one first engaging-element (320a) is built as first locking-element protruding transversely to a longitudinal axis (A) of the securing-section (320), wherein the at least one support frame engaging-element (410a) is built as a recess corresponding to the at least one first locking-element,
wherein the light guide adapter (300) can be brought into an intermediate position (P1) by inserting the securing-section (320) into the mounting-opening (410), such that the first locking-element (320a) passes through the recess (410a) and the base-section (310) abuts a portion of the support frame (400), which surrounds the mounting-opening (410), and
wherein the light guide adapter (300) can be brought into an end position (P2) by rotating the light guide adapter (300) starting from the intermediate position (P1) around the longitudinal axis (A) of the securing-section (320), such that the at least one first fastening-opening (311) and the at least one second fastening-opening (411) are overlapped, and the fastening-element (110) is received through both the at least one first fastening-opening (311) and the support frame fastening-opening (411).
