Abstract (en)

[origin: EP2306075A2] The headlight has a light module comprising a matrix-like arrangement of semiconductor sources i.e. LEDS, a primary lens (3) and a secondary lens. Light emission regions (36, 38, 40) comprising light emission surfaces, which differentiate middle rows (34) in the form of light emission surfaces of adjacent rows (44, 46). A middle light emission region of the middle rows is separated from the adjacent light emission regions of the middle rows by two V-shaped edges during reflection by the secondary lens. The edges are tapered together.
