摘要 | A light source, such as an LED, is provided with a multifaceted reflector to facilitate coupling of emitted light into an optical waveguide such as an optical fiber. In a preferred embodiment, a conventional LED fabricated on one side of a transparent substrate is provided with a series of integral concentric reflecting rings on the opposite side of the substrate. The rings reflect light diverging from the LED toward the central axis of an optical fiber light. |
其他摘要 | 诸如LED之类的光源设置有多面反射器,以便于将发射光耦合到诸如光纤的光波导中。在优选实施例中,在透明基板的一侧上制造的传统LED在基板的相对侧上设置有一系列整体同心反射环。环反射从LED发散的光朝向光纤光的中心轴。 |
