專利摘要(中)
The present invention discloses a light conversion material with light reflective structure, comprises: a transparent substrate, a plurality of first light conversion films and second light conversion films. Particularly, the second light conversion film is disposed between two of the first light conversion films, and has a refractive index greater than that of the first light conversion film. By such design, when a short-wavelength light is incident on the first light conversion films and the second light conversion films, parts of the short-wavelength light have a reflected light forming at the junction between the two light conversion films, and the reflected light would bounce back to the first light conversion film and/or the second light conversion film, thereby those unconverted short-wavelength light being prevented from directly passing the light conversion material. Briefly speaking, this light conversion material exhibits an outstanding performance on short-wavelength light recycling.
