<P>PROBLEM TO BE SOLVED: To provide a printing system (100) for printing digital images on a photosensitive medium (140) by using a light source (20) using various LED (Light Emitting Diode) arrays for the purpose of exposure energy. <P>SOLUTION: The printing system (100) may form print images of one color at a time or may simultaneously use all colors by continuous adjustment. The arrangement of the separated LEDs (32) may include the high-density systems molded by condensing cones (41) which are arranged as multiplexed cone structures (141) accompanied by parabolic type reflectors (65) or collimator lenses (36). The large-area LED (46) may alternately be arranged on, for example, an inclined mounting surface and may thus be used. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
