用于提高基于LED的照明器的效率的折叠光学方法和装置
摘要：
一种混合透镜经由折射和反射来准直光源发射的光。所述透镜的折叠光学元件包括外反射表面、透镜输出表面和中空芯，所述中空芯包括具有弯曲轮廓的侧壁、芯输出边界和芯输入开口，所述光源发射的所述光通过所述芯输入开口进入所述中空芯。所述透镜的反射器接收所述光源发射的所述光，将所述光的第一部分反射到所述折叠光学元件的所述中空芯中，并且将所述光的第二部分直接透射到所述中空芯中，而不会被所述反射器反射。在一个实例中，所述透镜输出表面具有65毫米的直径，所述透镜具有约13.5毫米的厚度(在所述光源和所述透镜输出表面之间)，并且提供具有12度或更小的光束发散角的基本准直的光。
摘要（英）：

A hybrid lens collimates light emitted by a light source via refraction and reflection. A folded optic element of the lens comprises an outer reflective surface, a lens output surface, and a hollow core comprising a sidewall having a curved profile, a core output boundary, and a core input opening through which the light emitted by the light source enters the hollow core. A reflector of the lens receives the light emitted by the light source, reflects a first portion of the light into the hollow core of the folded optic element, and directly transmits a second portion of the light into the hollow core without reflection by the reflector. In one example, the lens output surface has a diameter of 65 millimeters, the lens has a thickness (between the light source and the lens output surface) of about 13.5 millimeters and provides substantially collimated light with a beam divergence angle of 12 degrees or less.
