Abstract
A vehicle lamp assembly comprises a light source (16), a light
transmitting outer element (24) and a cylindrical light transmitting
intermediate element (18) disposed between the light source (16) and the outer
element (24) with the light source (16) on its cylinder axis. The intermediate
element (18) has elongate Fresnel prism formations (22) of uniform cross
section on its outer surface which extend in respective planes perpendicular to
the cylinder axis so as to collimate light from the light source (16) into said
planes. A second set of elongate Fresnel prism formations (26, 28), formed on
the outer element (24), is oriented parallel to the cylinder axis of the
intermediate element (18).
