Abstract
An optical wavelength-converting device used for converting a first waveband light includes a substrate, a phosphor layer and a composite reflection layer. The phosphor layer is disposed on the substrate for converting the first waveband light into a second waveband light. The composite reflection layer includes a first reflection layer and a second reflection layer. The first reflection layer is disposed between the substrate and the phosphor layer and adjacent to the substrate for reflecting the second waveband light, such that the second waveband light is transmitted through the phosphor layer so as to be outputted. The second reflection layer is disposed between the first reflection layer and the phosphor layer for adjusting the reflection spectrum of the first reflection layer, thereby enhancing the reflection rate of the composite reflection layer. As a result, the output efficiency of the wide-angle and wide-spectrum light is increased.
