<P>PROBLEM TO BE SOLVED: To provide a luminaire wherein labor for wiring is reduced. <P>SOLUTION: This luminaire is equipped with a circuit board 2 to which a plurality of light emitting diodes and the circuit components of a lighting circuit are mounted. Lands 21a, 21b to which terminals of nine light emitting diodes LED 1-9 are connected are provided on the mounting surface 2a of the circuit board 2, and a circuit 24 to connect the light emitting diodes LED 1-9 in series by wiring patterns 23a-23h which connects between the lands 21a, 21b is composed. In addition, lands 22a, 22b to which the terminals of four light emitting diodes LED 11-14 are connected are provided on the mounting surface 2a, and a circuit 26 to connect the light emitting diodes LED 11-14 in series by wiring patterns 25a-25c which connect between the lands 22a, 22b is composed. The wiring patterns 23a-23h composing the circuit 24 are formed by a route through which they do not mutually cross the wiring patterns 25a-25c composing the circuit 26. <P>COPYRIGHT: (C)2007,JPO&INPIT |
