Patent ID: 7762701

Claim:
An automotive rear combination lamp ( 10 ), comprising: an inner cylinder ( 61 ) having a proximal end and a distal end opposite the proximal end, the inner cylinder ( 61 ) comprising a convex cylindrical reflective surface ( 65 ); an outer cylinder ( 43 ) surrounding the inner cylinder ( 61 ), the outer cylinder ( 43 ) comprising a concave cylindrical reflective surface ( 45 ) coaxial with and facing the convex cylindrical reflective surface ( 65 ), the convex and concave cylindrical reflective surfaces ( 65 , 45 ) transversely defining a light propagation region; a printed circuit board ( 31 ) disposed at the proximal end of the inner cylinder ( 61 ); a plurality of light emitting diodes ( 35 ) disposed on the printed circuit board ( 31 ), the diodes ( 35 ) being capable of being electrically powered by the printed circuit board ( 31 ), the diodes ( 35 ) being capable of generating light that propagates longitudinally away from the printed circuit board ( 31 ) in the light propagation region; and an outwardly-flared reflector ( 75 ) disposed at the distal end of the inner cylinder ( 61 ) and adjacent to the light propagation region, for transversely reflecting light that propagates longitudinally in the light propagation region, the flared reflector having an increasing cross-sectional diameter from proximal to distal ends.
