In order to provide an LED light emitting device that can easily control a color temperature of white light, the LED light emitting device is provided with a plurality of types of light emitting parts that: respectively have LED elements that emit ultraviolet radiation or violet color visible light, and phosphors that absorb the ultraviolet radiation or violet color visible light to emit colored light; and emit the colored light, wherein: the colored light emitted by the plurality of types of light emitting parts become white light when all mixed with each other; the LED elements of the plurality of types of light emitting parts are all the same ones, and mounted on a single base material; and two or more light emitting parts overlap with each other in their parts.

LED light emitting device

On the light radiation device X A side, a box structure is provided in which a lens is held one by one proximate to or close to the light emission end of each optical fiber. On the light source device side, a common casing houses a first light source lens that generally collimates the radiation light beams radiated from an LED and a second light source lens that condenses the light beams from the first light source lens and introduces the condensed light beams to the light introduction end of the optical fiber bundle. Thus, the current demands of tests on a piece of work can be fully satisfied in view of the light condensing area and the light condensing efficiency while making the best of the characteristics of the illumination system in which the light radiation device and the light source device are separated with an intervention of the optical fibers.
