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.

Abstract: A wavelength-converting device includes a substrate and a reflective layer. The reflective layer is disposed on the substrate, among which when an operating temperature of the reflective layer is higher than or equal to 130° C., the reflective layer is formed of a first metallic material, and when the operating temperature of the reflective layer is lower than 130° C., the reflective layer is formed of a second metallic material. The reflectivity of the second metallic material is higher than the reflectivity of the first metallic material at room temperature. By forming the reflective layer of the first metallic material and the second metallic material at different operating temperatures, respectively, the decay of the reflectivity is effectively avoided, the reflectivity is optimized, and the converting efficiency of the wavelength-converting device is enhanced.

Abstract: An illumination module includes a lens and a plurality of light-emitting elements. The light-emitting elements are symmetrically arranged in a ring shape around a central axis. A plurality of lights are emitted and transmitted to the lens by the light-emitting elements. The lights, which are incident to the lens, are symmetrically arranged in a ring shape around the center of the lens, so that each of the lights transmitted through and outputted from the lens has the same refraction angle as each other. As a result, the tolerance issues are avoided, the fabrication cost and time cost are reduced, the difficulty of fabricating and designing are reduced, and the energies of the focused light point are equally distributed.
