PURPOSE: A conversing lens with a multiple-curvature compound surface, a collector module including the same, and a lighting device are provided to generate a beam with a light pattern and light intensity which satisfy lighting conditions. CONSTITUTION: A conversing lens includes an incident surface(11) and an emission surface(12). At least one point source(2) is arranged on one surface of the conversing lens. A crest line of an X axial direction and a crest line of a Y axial direction are divided into four curvature surfaces. A first curvature surface and a second curvature surface cross the crest line of the X axial direction. The first curvature surface and a fourth curvature surface cross the crest line of the Y axial direction. |
