LIGHTING DEVICE

摘要

A lighting device comprising a plurality of optical devices (10) arranged in a planar distribution and a first lens plate (30) is presented. Each optical device (10) comprises at least one radiation source (11) and an optical element (12) being arranged to create a substantially collimated radiation beam (20) from radiation generated by the at least one radiation source (11), and the first lens plate (30) extends along the plurality of optical devices (10) and comprises a plurality of first sub-lenses(31), in which each first sub-lens (31) projects a part of the radiation beam (20) at an illumination window (50), such that the projections of each first sub-lens (31) at least partially overlap. Also, a method for providing such lighting device is presented.
