Patent ID: 7810975

Claim:
A light unit comprising: a light emitting diode ( 20 ) having a light emitting chip ( 22 ; 23 ; 24 ; 25 ) as a light source for emitting light in a direction of light propagation ( 15 ); primary optics ( 30 ) optically connected to said light emitting diode ( 20 ) to receive the light emitted therefrom; and a secondary lens ( 91 ) optically coupled to said primary optics ( 30 ) for further directing the light emitted by said light emitting diode ( 20 ); wherein said primary optics ( 30 ) includes a fiber-optic element ( 31 ) widening in the direction of light propagation ( 15 ), said fiber-optic element ( 31 ) having a bottom surface ( 71 ) and a cover surface ( 51 ), each having an oppositely curved section ( 76 , 62 , respectively) adjacent to a light entry surface ( 32 ) of said fiber-optic element ( 31 ) wherein one of said curved sections ( 76 , 62 ) includes an inflection point ( 66 ) and one of said curved sections ( 76 , 62 ) has at least two curved surface sections ( 72 , 73 ) arranged offset relative to each other defining an angled transition area ( 75 ) extending therebetween.
