OPTICAL DEVICE, LIGHTING DEVICE AND LUMINAIRE

摘要

The invention relates to an optical device comprising a mutually spaced first and second optical layer, each comprising reflective, refractive and/or total internal reflection (TIR) purposely oriented, non-scattering shaping elements. The optical device is configured to a) transform light from a light source into a beam of uniform, pre-shaped light by the first optical layer, and subsequently b) fine-tune and condense said beam of uniform, pre-shaped light into a beam of uniform, end-shaped, condensed light by the second optical layer. Optionally a third optical layer is provided to subsequently collimate the beam of uniform, end-shaped, condensed light into a parallel beam of uniform, end-shaped, collimated light. The invention further relates to a lighting device comprising said optical device and to a luminaire comprising said lighting device.
