More Information
Summary:The invention provides a lighting device (1000) comprising a multi-layer PCB stack (100) comprising n stacked layers (110), wherein n≥2, wherein k layers (110) of the n stacked layers (110) each comprises a PCB (200) with a solid state light source (10), wherein 2≤k≤n, wherein the solid state light sources (10) are configured to generate light source light (11), wherein the layers (110) are shaped and stacked such that the light source light (11) of a 5 light source (10) of any of the PCBs (200) is at least partly not physically blocked by any of the other PCBs (200).
