双聚焦手电筒
摘要：
公开的是优化泛光束与聚光束两者的光输出与光束聚焦的手电筒。所公开的手电筒包括外壳构件与透镜，该透镜包括适配成使光束成形为聚光束的第一聚焦元件与适配成使光束成形为泛光束的第二聚焦元件。第一LED被定位成引导光穿过第一聚焦元件，第二LED被定位成引导光穿过第二聚焦元件。第一LED具有比第二LED更小的管芯，并且第一LED与第一聚焦元件之间的距离比第二LED与第二聚焦元件之间的距离更大。
摘要（英）：

Disclosed are flashlights that optimize the light output and beam focus of both a flood beam and a spot beam. The disclosed flashlights include a housing member and a lens including a first focusing element adapted to shape a light beam into a spot beam and a second focusing element adapted to shape a light beam into a flood beam. A first LED is positioned to direct light through the first focusing element, and a second LED positioned to direct light through the second focusing element. The first LED has a smaller die than the second LED, and the distance between the first LED and the first focusing element is greater than the distance between the second LED and the second focusing element.
