Patent ID: 8360615

Claim:
A light module comprising: at least one light emitting diode (LED) for emitting light with wide divergence; and a reflective light transformer being rotationally symmetrical and having a vertex located on an axis of symmetry coincident with an optical axis of the LED, wherein in order to obtain high efficiency, a surface profile of the reflective light transformer is defined by an equation R (α;θ)= F{I s (α); I p (θ)} wherein R(α;θ) is the surface profile of the reflective light transformer, α is an angular coordinate relative to an axis of symmetry of the reflective light transformer belonging to a domain of the LED, θ is an angular coordinate relative to an orthogonal axis to the axis of symmetry belonging to a pattern domain, I s is a light source spatial intensity distribution, I p (θ) is a required intensity distribution across an emitted pattern, and F{ } is an arbitrary functional determined by a method of design, wherein the reflective light transformer collects light emitted by the LED, compresses, redistributes, and directs collected light with high efficiency in an omnidirectional pattern with pre-calculated intensity distribution.
