LAMP UNIT COMPRISING A SHIELD HAVING AT LEAST ONE LIGHT WINDOW

摘要

A lighting unit for a headlight, in particular a motor vehicle headlight, having at least two light sources (1a, 1b), at least one reflector (2a, 2b), which delimits two light chambers (3a, 3b), a bezel (4), and a projection lens (5) having an optical axis (A), wherein a light chamber (3a) is arranged on an upper side and a light chamber (3b) is arranged on an underside of the bezel (4), wherein at least one light source (1a, 1b) is arranged within each of the light chambers (3a, 3b) and the bezel (4) extends substantially as far as a focal plane (E) of the projection lens (5) in order to produce a sharp light/dark boundary in a light exposure produced by the lighting unit, wherein the bezel (4) has at least one light window (7a, 7b), wherein at least one light path (8a, 8b, 8c, 8d) extends outwardly from a light chamber (3a, 3b), through the at least one light window (7a, 7b) and through the projection lens (5).
