It is an object of the present invention to permit division of an LED wiring board into various sizes to permit its use before and after the division, and also simplify operation of this division and simplify circuit design. More specifically, in the present invention, wiring patterns (P4) and (P5) for energizing LEDs (21) are formed in a planar direction of the LED wiring board (2). Division grooves (2M) for dividing the LED wiring board 2 into a plurality of sub-boards are formed on the front surface of the LED wiring board (2) in a perpendicular direction and are provided in a manner such as to cross the wiring patterns (P4 and P5) in the planar direction. Use with the entire board before the division by the division grooves (2M) is possible, and use with division elements divided along any of the division grooves 2M is also possible. |
