    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 first substrate, a second substrate and a first wavelength-converting material. The first substrate has a first region and a first engagement portion. The second substrate is disposed adjacent to the first substrate and having a second region and a second engagement portion. The second engagement portion and the first engagement portion have complementary shapes. The first wavelength-converting material is disposed on the second region for converting a light in a first waveband into a light in a second waveband. The light in the first waveband is transmitted through the first region, and the light in the second waveband is reflected by the second region. The first region and the second region are staggered, so that the first engagement portion and the second engagement portion are engaged and fixed with each other. As a result, the safety and stability are enhanced, and the noise is reduced.
