ABSTRACT:
In a lighting unit for projecting forward diverging light emitted from a light source, a prism is disposed forward of the center of the light source. The prism has a first light incident surface through which light emanating obliquely forward from the light source enters the prism, a total reflection surface which reflects forward in total reflection light passing through the first light incident surface, a second light incident surface which is a positive refracting surface and through which light emanating mainly forward from the light source enters the prism and a light emanating surface through which light passing through the second light incident surface and light reflected by the total reflection surface emanate from the prism. A reflecting mirror reflects mainly forward light emanating sideways and rearward from the light source.
