Luminaire assembly comprising: a light source (100), a support (200) for carrying the light source, a protector (300) for protecting the light source (100) from external environmental influences, the protector (300) having an open top (310) for accommodating the support (200), a bottom (320) facing the light source (100) and a peripheral wall (330) between the open top (310) and the bottom (320). The peripheral wall comprises a transparent or translucent portion. The light source is configured to send light in use through said portion of the peripheral wall. The protector is provided with a light absorbing surface arranged inside of the protector and facing the light source. The light absorbing surface is configured such that in use part of the light emitted from the light source is absorbed by the light absorbing surface to reduce upward light pollution.
