Abstract:
A lighting device having a cell structure (101) of polygonal cells (105), which is a heat sink, and light sources (103) arranged to be cooled by the cell structure. The light sources are arranged in at least some of the cells, one light source in each cell. The light sources are attached to the cell structure and electrically connected with the cell structure, which in turn is arranged to provide the light sources with power.
