Zusammenfassung:PURPOSE: A lighting apparatus is provided to remove an easy color change and a color coordinate yield by using a wavelength conversion member in which a fluorescent substance and a transmitting substance are mixed. CONSTITUTION: A lighting apparatus(2) includes at least one LED(22), a solid wavelength conversion member(23), a support unit(24), and a reflecting member(21). The wavelength conversion member includes a fluorescent substance(232) which converts wavelength of light come from an LED. In both sides of the wavelength conversion member, grooves are formed. The support unit detachably supports the wavelength conversion member placed in an upper part of the LED. The bearing unit includes a support stand(242) and a spring unit(243). The support stand has protrusions inserted into the grooves. The spring unit deflects the support stand in the direction in which the spring unit is engaged with the grooves. The reflecting member is arranged to surrounds at least one LED.
