Abstract
A number of red LEDs, green LEDs, and blue LEDs are mounted on one surface of a polygonal flexible multilayer substrate. The LEDs are connected in series according to color. A red feeder terminal, a green feeder terminal, a blue feeder terminal, and a common terminal are provided on each of at least three sides of the periphery of the flexible multilayer substrate. Circuit patterns for connecting LEDs at the high-potential end of the red, green, and blue series-connected LEDs respectively to the red feeder terminals, green feeder terminals, and blue feeder terminals are provided to the flexible multilayer substrate. Also, a circuit pattern for connecting LEDs at the low-potential end of the red, green, and blue series-connected LEDs all to the common terminals is provided to the flexible multilayer substrate.
