| description | PROBLEM TO BE SOLVED: To provide an illuminating device that can improve brightness of an irradiated surface and quality of illumination on an illuminated surface, and can reduce the number of used kinds of light-emitting diodes to two kinds. SOLUTION: A substrate 23 is provided with a first light-emitting section 31, and a second light-emitting section 37 and a third light-emitting section 41, which are adjacent to the light-emitting section 31 and have a light-emitting area smaller than the first light-emitting section. The first light-emitting section 31 comprises a plurality of first blue LEDs 32 emitting blue light, a first translucent sealing member 33 sealing the blue LEDs 32 and fluorescent material mixed into the sealing member 33 and excited by blue light, and emits light in green or yellow. The second light-emitting section 37 comprises a plurality of second blue LEDs 38 emitting blue light and a second translucent sealing member 39 sealing the blue LEDs 38. The third light-emitting section 41 comprises a plurality of red LEDs 42 emitting red light and a third translucent sealing member 43 sealing the red LEDs 42. COPYRIGHT: (C)2010,JPO&INPIT |
