摘要: An illumination system (3) includes a solid-state light-emitting element (31) and wavelength-converting device (32). A light (L1) in first waveband is emitted to an optical path (P) by the (31). The (32) disposed on phosphor plate (321). (321) solid mixture having agent binder. weight percent of from 10 70, such that transformed into (L2) second waveband. Under this circumstance, efficiency heat conduction effectively enhanced, thereby enhancing conversion (32), which strong enough be applied rotate with great rigidity. Meanwhile, not only space requirement reduced, but also phenomena hot spot diffusion are avoided, cost difficulty manufacturing significantly reduced.
