Illumination device

摘要

Today the use of false ceilings is decreasing as it involves to high energy consumption. The tendency nowadays is to have bare concrete ceilings onto which luminaires are mounted, which often causes acoustical problems. The invention deals with these acoustical problems and relates to an illumination device (1) comprising a concave reflector (2) bordering with an outer edge (3) a light emission window (4). The reflector has a reflective surface (7) facing the light emission window. The illumination device further comprises lamp holding means (8) for accommodating a light source (9) and being positioned in between the reflective surface and the light emission window. The illumination device is characterized in that the reflector is made of acoustically absorbing material.
