Patent ID: 11953170

Abstract:
Illumination device (ID) for a motor vehicle headlamp. The ID includes a light source for emitting a light beam (LB) with a first vertical extent (VE), an optic body (OB) for guiding the LB, and an optical system for projecting the LB in front of the ID. The OB includes a first pair of optically operative surfaces for guiding the LB coupled into the OB. The first pair of optically operative surfaces consists of a first and second light deflection surface configured to deflect the LB while travelling through the OB. The first and second light deflection surfaces are configured such that light rays forming the LB are essentially parallel to each other and to a main direction after being coupled out of the OB. The outcoupled parallel LB has a second VE in the main vertical cross section, wherein the second VE is greater than the first VE.
