The present invention relates to a mixed-light generation apparatus that generates mixed-light using three or more LED-fluorescent combinations, which can thereby easily realise multi-coloured mixed-light, and can thereby generate mixed-light having a high colour rendering index. The mixed-light generation apparatus of the present invention in this regard is a mixed-light generation apparatus that generates mixed-light by mixing light generated from three or more LED-fluorescent combinations comprising an LED chip and a phosphor layer that is excited by an excitation wavelength of the LED chip and that emits light, wherein three or more of the LED-fluorescent combinations are configured to generate light corresponding to different coordinate values based on the CIE 1931 colour coordinate system, and the mixed-light is configured to be controllable within an area enclosed by three or more of the different coordinate values by respectively controlling driving currents that are supplied to three or more of the LED-fluorescent combinations. |
