Zusammenfassung:	A converging lens with a multiple-curvature compound surface is revealed. The converging lens includes an incident surface and an emission surface. A crest-line along X axis and a crest-line along Y axis are on the emission surface, crossed each other and dividing the emission surface into four curved surface sections. The X-axis curvature as well as the Y-axis curvature of each curved surface section can be the same or different. An angle theta between the crest-line along X axis and the X-axis ranges from 0~30 degrees. Thereby light from a light sources passes through the converging lens and projects to produce a light pattern required. The converging lens is used in concentrator modules and lighting fixtures.
