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.

Abstract: An illumination system includes a solid-state light-emitting element and a wavelength-converting device. A first waveband light is emitted to an optical path by the solid-state light-emitting element. The wavelength-converting device is disposed on the optical path and includes a phosphor plate. The phosphor plate is a solid mixture having a phosphor agent and a binder. The weight percent of the phosphor agent is from 10 to 70, such that the first waveband light is transformed into a second waveband light. Under this circumstance, the efficiency of heat conduction of the phosphor plate is effectively enhanced, thereby enhancing the converting efficiency of the wavelength-converting device, which is strong enough to be applied to rotate with great rigidity. Meanwhile, not only the space requirement is reduced, but also the phenomena of hot spot and heat diffusion are avoided, such that the cost and difficulty of manufacturing the wavelength-converting device are significantly reduced.
