<p>A vehicle lamp comprising a light source (10) and a Fresnel lens (12) arranged to collimated light from the light source (10). The Fresnel lens (12) has a zone (16) carrying annular reflecting prism formations (18), and a concave reflector (26) positioned surrounding the light source (10) and extending towards the periphery of the lens (12). The reflector (26) is shaped so as to reflect light from the light source (10) on to the radially outer faces of the reflecting prism formations (18) at an angle such that it is collimated by the reflecting prism formations (18). <IMAGE></p> |
