We present a fast step-by-step method to design double free-form LED lens quickly; tiny rectangular light field with high efficiency can be achieved. Lens construction just need to derive two contour lines according to geometrical optics analysis. Le

We have designed a new TIR(Total Internal Reflection) structure for generating an LED lens which can produce a rectangular beam with small divergence angle in two perpendicular directions for an optical guidance system. The lens can control the diver
