Abstract
A lighting device having a simplified connection configuration between light sources and a light source driver is provided. A backlight unit 12 according to this invention includes a plurality of LED boards 18 on which LEDs 17 are mounted. The LEDs 17 are light sources. Each LED board 18 includes a connection wiring pattern 27 electrically connected to the LEDs 17 and a through wiring pattern 28 not electrically connected to the LEDs 17. The connection wiring pattern 27 is connected to the through wiring pattern 28 on the other LED board 18. The connection wiring pattern 27 of each LED board 18 electrically connected to the LEDs 17 is electrically connected to the through wiring pattern 28 of the other LED board 18 not electrically connected to the LEDs 17.
Claims14
A lighting device comprising a plurality of light source boards including light sources mounted thereon, each light source board including a connection wiring pattern and a through wiring pattern, the connection wiring pattern being electrically connected to the light source and the through wiring pattern of the other light source board, the through wiring pattern not being electrically connected to the light source, wherein
- each light source board includes a first terminal portion at one end and a second terminal portion at another end, the first terminal portion including a first connection terminal and a first through terminal arranged adjacent to each other, the first terminal portion being provided at an end of the connection wiring pattern, the first through terminal being provided at an end of the through wiring pattern, the second terminal portion including a second connection terminal and a second through terminal arranged adjacent to each other, the second connection terminal being provided at another end of the connection wiring pattern, the second through terminal being provided at another end of the through wiring pattern, and
- the connection wiring pattern and the through wiring pattern include an intersection such that an arrangement of the first connection terminal and the first through terminal in the first terminal portion is different from an arrangement of the second connection terminal and the second through terminal in the second terminal portion.
