The present invention generally relates to the field of acoustically absorbing lighting devices, and in particular to an acoustic lighting tiles. Such an acoustic lighting tile (100) comprises a first light source (101) and a light guide panel (102). The first light source (101) is configured to provide, in operation, a first light source light. The light guide panel (102) comprises a bottom surface (111), a top surface (112) opposite to the bottom surface (111), and a first edge surface (113) that extends between the bottom surface (111) from the top surface (112), the first edge surface (113) being configured to receive the first light source light from the first light source (101). The light guide panel (102) comprises a plurality of slits (114), and at least part of each slit of the plurality of slits (114) tapers towards the first edge surface (113).
