PROBLEM TO BE SOLVED: To provide a compound LED light emitting device combining two kinds of a mixed color light emitting section of a multicolor mixed type using a R, G and B LED and a white light emitting section formed of B LED and YAG fluorescent material layer, which prevents trouble of color mixing property due to peak wavelength of monochromatic properties of respective R, G and B LED and can obtain sufficient color mixing property even in an area other than a light emitting front area as a white light source.SOLUTION: An LED light-emitting device for emitting white light with modulation means of a fluorescent material layer combined, and having an LED as a light emitting source includes: a mixed color light emitting section having combination of R, G and B fluorescent material layers modulating a near ultraviolet LED R, G and B; and a white light emitting section combining a YAG fluorescent material layer with a blue LED, and a plurality of white light emitting sections are arranged on a mounting board around the mixed color light emitting section. |
