FLEXIBLE UNOBSTRUCTED BEAM SHAPING.

摘要

The invention provides a lighting device (100) comprising a reflector (110) and a light source (120) configured to provide in the absence of an optical plate (130) a beam (2) of lighting device light (101) with an original optical axis (102) and an original opening angle (θ), wherein the lighting device (100) comprises said optical plate (130) configured within the reflector (110), wherein the optical plate comprises a light transmissive layer (131) comprising micro optical structures (132), and wherein the lighting device (100) including the optical plate (130) is configured to provide said beam (2) of lighting device light (101) having one or more of (i) a final opening angle (θf) with θf>θ, and (ii) a final optical axis (102f) having a non-zero angle (β) with the original optical axis (102).
