Beschreibung
Zusammenfassung:	The invention relates to a lighting device for room lighting which has a carrier plate (8) having a reflective assembly surface (89) on which a plurality of light emitting semiconductor chips (1) spaced apart from each other is arranged, and furthermore a translucent or transparent emission plate (20) arranged downstream of the light emitting semiconductor chips (1) in the emission direction and having a light decoupling surface (29) facing away from the light emitting semiconductor chips (1), wherein the emission plate (20) has a plurality of recesses (22) which are each arranged after at least one semiconductor chip (1), and wherein each of the recesses (22) has a diffusor material and/or a wavelength conversion material (21) on the inner surface (28) facing the semiconductor chips (1), and spaced apart from the light emitting semiconductor chips (1).
