    Abstract: A laser light source comprises a laser source and a ceramic phosphor tile having a light entry face for receiving laser light from the laser source for laser pumping by the laser light. A reflective coating is formed over a face opposite the light entry face. A metal layer is provided between a heat sink and the ceramic phosphor tile, wherein the metal layer has a melting point below 120oC. The metal layer thus becomes a liquid during operating temperatures, and this reduced strain on the phosphor layer while maintaining thermal contact.

    Abstract: 本发明提供的发光设备包括第一光源、第二光源、二向色镜、波长转换装置、第一光路调节装置或第二光路调节装置以及第一散射光学系统。在本发明中，通过使用第一散射光学系统可以改善出射光的混光效果。通过单独调节第一光源和第二光源的功率可以实现发光设备的出射光的色温的自由调节。还可以在第二光源中使用可出射不同主波长的光的激光器来提高发光设备的出射光的显色指数。本发明中的第一光源出射的光全部用于激发波长转换装置，相比于现有技术方案，本发明中所提供的发光设备可以在不增加光学扩展量的情况下实现更高光通量的输出，如果在第一光源中配合使用偏振选择元件，则可以再进一步提高发光设备的光通量的输出。
