Abstract
The invention provides a lighting system (), wherein the lighting system () comprises np system sections (), wherein n≥2, wherein each system section () comprises a light source array section (), a collimator section (), and a Koehler integrator section (), wherein: for each of the system sections () applies: the light source array section () comprises a plurality of section light sources () configured to provide light source light (); the Koehler integrator section () comprises a section entrance face () and a section exit face (), wherein the section entrance face comprises a plurality of section entrance lenslets () shaped according to an section entrance surface pattern (), and wherein the section exit face () comprises a plurality of section exit lenslets () shaped according to a section exit surface pattern (), and wherein the section entrance face () is configured in a light receiving relationship with the plurality of section light sources () via the collimator section (); each of the plurality of section light sources () have a light emitting surface (), wherein the light emitting surface () has a first axis of elongation Aand an aspect ratio RS, wherein RS>1; each first axis of elongation Ahas an angle αAto an averaged first direction of the axes of elongation A, wherein α≤5°; the section entrance surface pattern () comprises a section entrance tessellation () of an entrance lenslet shape, wherein the entrance lenslet shape has a rotational symmetry of order nA, wherein n≥2, wherein the entrance lenslet shape has an entrance aspect ratio Rand wherein R≤RS; the section exit surface pattern () comprises a section exit tessellation () of an exit lenslet shape, wherein the exit lenslet shape approximates the light emitting surface (), wherein the exit lenslet shape has an exit aspect ratio R, wherein Ris selected from the range of 0.8*RS−1.2*RS; and at least two system sections () of the system sections () are rotated relative to another for 360°/n/k+(360/n)*n, wherein m is anon-negative integer, and wherein k is selected from the range of 2-12.
