[origin: EP0953800A1] The light guide has a transparent body (3) provided by a tube or a tubular sector, positioned coaxially around the elongate light source (1). This provides grooves (5) extending parallel to its axis, which are equally spaced around the inside surface of the light guide. An Independent claim is included for a lamp with an elongate light source.
