Light source device

The invention provides a light source device. The light source device comprises a reflecting substrate and a plurality of light-emitting elements, the reflecting substrate is provided with a plurality of reflecting grooves. Each reflection groove is provided with a bottom curved surface and a side wall curved surface. The bottom curved surface is defined by a reference curved surface. The side wall curved surface surrounds the bottom curved surface and is defined by a reference paraboloid. The reference curved surface is different from the reference paraboloid. The light-emitting elements are arranged above the reflecting substrate and used for emitting light to the reflecting grooves. 本发明提供一种光源装置，其包括反射基板以及多个发光元件。反射基板具有多个反射槽。各个反射槽具有底部曲面与侧壁曲面。底部曲面由参考曲面定义而成。侧壁曲面围绕底部曲面，并由参考抛物面定义而成。参考曲面不同于参考抛物面。这些发光元件设置于反射基板上方，并用于对这些反射槽发出光线。
