A light guide 205 for a lighting apparatus comprises an elongate and substantially transparent member having opposed ends 220, 221. A longitudinal portion 222 of an outer surface 223 of the member is linearly recessed symmetrically about a transversal main axis 224 of the member. A transversal distance 225 of the recessed portion 222 relative to a longitudinal portion 226 of the outer surface opposed to the recessed portion 222 increases progressively in either direction away from the transversal main axis 224 of the member. A lighting apparatus comprises the light guide 205 and two light sources 210 located adjacent respective and opposed ends of the member. |
