REFLECTOR ASSEMBLY AND BEAM FORMING

摘要

A beam forming apparatus for forming a beam in a forward direction including a first reflector arranged to receive light from said source and to reflect it rearward, and a second reflector arranged to receive light from said first reflector and to reflect it forward. The rearmost reflector is hyperbolic in form, and the front reflector is advantageously elliptical. This arrangement offers multiple different beam patterns of varying and controllable concentration to be achieved in a consistent and predictable manner.
