PORTABLE LUMINAIRE |
摘要 |
A portable luminaire includes an optical module, a power source and a housing. The optical module has at least one light emitting diode (LED) that emits light with a wide divergence, a non-imaging optical element and a transparent window. The non-imaging optical element (NIO) has a refractive member located around a LED optical axis and a total internal reflection member located around the refractive member. The refractive member and the total internal reflection member are integrated in a single transparent element having a mutual focal point. The NIO element collects a significant amount of light emitted by the LED with wide divergence located at the focal point to compress the collected light with high efficiency into a required pattern with a generally different angular distribution in a horizontal plane and a vertical plane, and to direct the compressed light outside of the luminaire. |
