Abstract

The invention discloses a lighting device for a road lighting luminaire and a lighting luminaire comprising the lighting device. The lighting device comprises a reflector (301) which comprises a reflecting surface (3011) formed by revolving a parabolic curve around a first axis (y) through a predetermined angle wherein said parabolic curve has an aperture at its vertex said first axis being co planar with said parabolic curve and extending substantially perpendicularly to the axis (x) of symmetry of said parabolic curve and being located at or outside of said aperture of said parabolic curve. The lighting device further comprises a LED light source (302) which is disposed at an entry to said reflecting surface with said entry corresponding to said aperture of said parabolic curve. In this way light distribution can be controlled in the same way in any plane containing the first axis within the range of the predetermined angle. Moreover the light distribution in any plane containing the first axis (y) can be controlled as desired by designing the parabolic curve accordingly. Thus the lighting device can effectively reduce or eliminate the negative glaring effect and/or achieve satisfying lamination uniformity on the road surface.
