Patent ID: 7942558

Claim:
An optical device for the targeted reproduction of light emitted from LED light sources ( 6 ), comprising at least two individual optical parts of which one is a first individual optical part ( 10 ) in the form of a solid waveguide and a further individual optical part ( 10 ″) which mechanically connects to the LED light source, said first individual optical part ( 10 ) tapering in the z-direction, in a Cartesian coordinate system, proceeding from an x-y plane, characterized in that, said first individual optical part ( 10 ) has a longitudinal extent in the y-direction that is smaller than or equal to its longitudinal extent in the z-direction and smaller than or equal to its longitudinal extent in the x-direction, said first individual optical part ( 10 ) comprising first and second planar outer surfaces ( 14 ) opposing in the x-z plane, said first individual optical part ( 10 ) further comprising third and fourth planar or non-planar outer surfaces ( 16 , 20 ) substantially opposing in the x-y plane, said first individual part ( 10 ) further comprising fifth and sixth opposing outer surfaces ( 7 ) curved in a convex manner with regard to the y-z plane, said third and fourth outer surfaces ( 16 , 20 ) being square, and said fifth and sixth outer surfaces ( 7 ) being curved such that said fourth outer surface has an extent in the x- direction that is smaller than the extent of said third outer surface, wherein the face of said fourth outer surface ( 20 ) adjacent to the LED light source ( 6 ) contains a cut out ( 22 ) for refracting and transmitting the light from the source ( 6 ) towards the other faces of said first individual optical part ( 10 ).
