An illuminating device (90a) includes a plurality of LEDs (91) and a light guiding plate (93a). The light guiding plate includes a light incident surface (931) and a light output surface (932). A fluorescent material (938) is distributed in an inside of the light guiding plate. The LEDs are used to emit first light of a first wavelength to excite the fluorescent material thereby producing second light of a second wavelength. The LEDs and the fluorescent material are arranged in a manner that the combined first and second light emitted from the light output surface appears to be white light.
