Abstract
A plurality of groups of Light Emitting Diodes (LEDs), each group being made up of three LEDs with red, green, and blue luminous colors respectively, are mounted at positioning areas of a flexible substrate, on the wiring patterns formed on the top surface of the substrate. A plurality of heat dissipation boards are adhered to the bottom surface of the substrate using an adhesive so as to cover the areas corresponding to the positioning areas of the groups of LEDs.
