Abstract: An illumination system includes a wavelength-transforming device, a solid-state light-emitting element and a filter wheel. The wavelength-transforming device comprises a segment and a wavelength-transforming element disposed on the segment. The solid-state light-emitting element emits first color light in first waveband region to the wavelength-transforming device. The filter wheel is disposed on one side of the wavelength-transforming device for filtering lights via rotating. The first color light is excited as second color light in second waveband region by the wavelength-transforming device, so that the second color light is outputted with the rest of the first color light. The first and second color lights are transmitted through the filter wheel, such that three primary color lights are sequentially projected. The present invention achieves the advantages of reducing cost, simplifying fabricating processes, being available for high working temperature, and further improving image quality without using red phosphor agent or red solid-state light-emitting element.

Abstract: A phosphor device of an illumination system emitting a first waveband light includes a substrate and a phosphor layer formed on the substrate. The phosphor layer includes a first phosphor agent and a second phosphor agent. The first waveband light is converted into a first color light by the first phosphor agent. The second phosphor agent is distributed over the first phosphor agent and mixed with the first phosphor agent, and the first waveband light is converted into a second color light by the second phosphor agent. The first color light and the second color light are integrated into the second waveband light. The difference between the first wavelength peak of the first color light and the second wavelength peak of the second color light is 50 to 100 nanometers. Therefore, the advantages of increasing the purity, the luminance and the luminous intensity of specific color light are achieved.

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.
