Abstract

A lighting device comprising a housing with a light emission window and, opposite thereto, a reflector. A planar light transmissive carrier arranged in between the light emission window and the reflector and comprising, at least on a side facing towards the reflector, a grid of a plurality of light sources. The plurality of light sources comprise a first group of first light sources and a second group of second light sources. Each first light source has a respective first emission orientation in a respective first direction away from the reflector and each second light source has a respective second emission orientation to issue light towards the reflector, which light, after reflection, is redirected into a respective first direction. The lighting device is able to provide accent lighting and/or diffuse lighting issued by light sources arranged on one planar carrier.
