<p>Disclosed is an LED light source wherein an LED chip and a fluorescent body are used. The LED light source is configured such that the chromaticity of synthesized light to be emitted from the LED light source can be adjusted to a predetermined chromaticity, even if the chromaticity of light emitted from the LED chip and the chromaticity of excitation light emitted from the fluorescent body vary. The LED light source (10, 11) is provided with a light emitting section (2), which has the LED chip (21) and the fluorescent body (22), and which emits the synthesized light of the first light (R1) emitted from the LED chip, and the second light (R2) emitted from the fluorescent body by being excited by the first light. Furthermore, the LED light source is provided with reflecting members (a reflector (3) and a reflecting sheet (4)) which emit third light (R3) corresponding to the first light (R1) and the second light (R2) so as to adjust the chromaticity of the synthesized light to the desired chromaticity.</p> |
