Double-ellipsoid road lamp brightness uniformity light distribution lens and road lamp applying same

The utility model provides a double-ellipsoid road lamp brightness uniformity light distribution lens and a road lamp applying the double-ellipsoid road lamp brightness uniformity light distribution lens. The double-ellipsoid road lamp brightness uniformity light distribution lens comprises a big half ellipsoid body and a small half ellipsoid groove, the shape of the small half ellipsoid groove is formed along the section of the long axis, the big half ellipsoid body is a formed shape parallel to the long axis, the thickness of the formed shape is larger than that of the section on the semiaxis, the long axis of the big half ellipsoid body is perpendicular to the long axis of the small half ellipsoid groove, and the section of the big half ellipsoid body and the section of the small half ellipsoid groove are located in the same plane. According to the double-ellipsoid road lamp brightness uniformity light distribution lens, light of an area light source is deflected through the double-half-ellipsoid lens, finally road lamp brightness uniformity light distribution is achieved, the brightness uniformity of road lighting is improved, and light energy emitted by the light source is reasonably applied to the maximum.
