Method and device for producing recesses in the coating of transparent components of a lighting device

A method, comprising:

• producing recesses in a coating, the coating including a first coating and a second coating, of a transparent frame surrounding a light guide body of a vehicle headlight, the coating having been deposited on the frame, the recesses being produced by locally removing the coating using a laser beam generated by a single laser beam source, said producing recesses comprising:
• removing the first coating on a front face of the frame using the laser beam that is directed from a front face of the first coating onto the frame to produce recesses in the first coating;
• removing the second coating on an opposite rear face of the frame using the laser beam that is subsequently directed from the front face of the first coating onto the frame and removes the second coating by passing through the frame by subsequently directing the laser beam through recesses formed in the first coating;
• and
• adjusting the distance of the laser beam source to the frame such that the laser beam is focused on the front face of the frame for removing the first coating and is focused on the rear face of the frame for removing the second coating,
• wherein the laser beam is deflected using a scanner system so that recesses are produced on the front and rear face of the frame,
• wherein the first coating and the second coating are removed in a single clamping of the frame,
• wherein the laser beam is not absorbed by a material of the transparent frame and the laser beam is only absorbed by the coating, and
• wherein the recesses produced on the front and rear face of the frame are produced with a same shape.
