Patent ID: 7645061

Claim:
Low beam headlight with at least one light module, wherein the individual light module exhibits at least one light source and at least one primary lens connected downstream of the light source; and wherein the light source is a luminescent diode, characterized in that the low beam headlight ( 10 ; 210 ; 410 ) has at least one secondary lens ( 90 ; 290 ; 490 ), which is connected optically downstream of the primary lens ( 50 ; 250 ; 450 , 650 ) or the primary lenses ( 50 ; 250 ; 450 , 650 ), that both the primary ( 50 ; 250 ; 450 , 650 ) and the secondary lens ( 90 ; 290 ; 490 ) exhibit at least two lens segments ( 61 , 71 , 81 ; 101 , 111 , 121 ; 261 , 271 , 281 ; 301 , 311 , 321 ; 461 , 471 , 481 ; 501 , 511 , 521 ; 661 , 671 , 681 ), which are arranged one over the other, that at least one lens segment ( 61 , 71 , 81 ; 261 , 271 , 281 ; 461 , 471 , 481 ; 661 , 671 , 681 ) of a primary lens ( 50 , 250 , 450 , 650 ) is assigned to a lens segment ( 101 , 111 , 121 ; 301 , 311 , 321 ; 501 , 511 , 521 ) of a secondary lens ( 90 , 290 , 490 ), that at least one lens segment ( 61 , 261 , 461 , 661 ) of the primary lens ( 50 , 250 , 450 , 650 ) and its assigned lens segment ( 101 , 301 , 501 ) of the secondary lens ( 90 , 290 , 490 ) lie outside optical axis ( 25 ) of the light module ( 20 ; 220 ; 420 ; 620 ), that at least light emergence surface ( 64 , 264 , 464 , 664 ) of this lens segment ( 61 , 261 , 461 , 661 ) of the primary lens ( 50 , 250 , 450 , 650 ) exhibits at least one envelope surface that is biaxially curved, and that a sum of radii of curvature of at least one surface element of the envelope surface of this light emergence surface ( 64 , 264 , 464 , 664 ) in two planes that are normal to each other is less than the sum of the radii of curvature of at least one surface element of the envelope surface of at least one other light emergence surface ( 74 , 84 ; 274 , 284 ; 474 , 484 ; 674 , 684 ) of the primary lens ( 50 , 250 , 450 , 650 ) in two planes that are normal to each other.
