A lighting device (100, 200, 500, 501, 700, 705) is provided comprising a plurality of solid state light sources (120, 220A, 220B, 520, 620, 720) arranged on top surfaces of a plurality of substrates (550, 650, 750). The substrates are at least partly transparent for visible light and form a major part of a housing (110, 210) which defines a cavity (114, 214, 514). The top surfaces of the plurality of substrates face the cavity and each of the plurality of solid state light sources is positioned such that, in operation, each of the plurality of solid state light sources emits light in a direction away from the top surfaces of the plurality of substrates. |
