<p>A lens unit array condenser, comprising: a substrate (3) having a planar bottom surface and a condensing focal point (O) thereabove; a support piece array disposed on the upper surface of the substrate; and a lens unit (1) connected with the support surface of each support piece (2) forming the support piece array. The lens unit is a rectangular plane, and is disposed facing the condensing focal point; the incident light perpendicular to the substrate is reflected from the geometrical center of each lens unit, and the reflected light is condensed at the condensing focal point. The lens unit array condenser has simple manufacturing process, low cost and good condensing effect.</p> |
