<P>PROBLEM TO BE SOLVED: To prevent ununiformity in luminance from being caused by asymmetry of orientation characteristics (directivity S) of LEDs, while minimizing a wiring length and maintaining a wiring area for heat radiation. <P>SOLUTION: A plurality of LEDs 3 are mounted on a substrate in such a manner that all directions from anodes of the plurality of LEDs 3 to cathodes of them are identical with one another between the adjacent LEDs 3. Thus, since disposition directions of the respective LEDs 3 are aligned with one another, "lightness" and "darkness" do not alternately appear between the adjacent LEDs 3, and ununiformity in luminance is prevented in an LED module 1 in which the plurality of LEDs 3 are vertically disposed in line. <P>COPYRIGHT: (C)2012,JPO&INPIT |
