Light-emitting panel with transparent cellular support panel

摘要

The present invention relates to alight-emitting panel (1) comprising: a first panel sheet (11), the first panel sheet being optically transparent; a second panel sheet (12); and a cellular support panel (10) sandwiched between the first panel sheet and the second panel sheet. The cellular support panel comprises optically transparent cell walls (13) defining a plurality of tubular channels (14) extending from the first panel sheet towards the second panel sheet. The light-emitting panel (1) further comprises a two-dimensional light-source array (15;16;24;27) comprising a plurality of light-sources (18a-b;19a-b) each being arranged to emit light into at least one of the tubular channels of the cellular support panel. Various embodiments of the present invention provide a cost-efficient light-emitting panel with advantageous light-emission and mechanical properties.
