Abstract
The present invention relates to a light-emitting building element () comprising a plurality of solid-state light sources (); and a sound-absorbing element () having an optically reflective side (). The sound-absorbing element () is arranged such that the optically reflective side () faces the plurality of solid-state light sources (), and comprises a plurality of holes () through the sound-absorbing element from the optically reflective side to an opposite side () of the sound-absorbing element. Each of the holes () is configured such that a projection of the hole in a plane parallel to the sound-absorbing element () is smaller than a smallest area of a cross-section of the hole (), the cross-section being perpendicular to a normal of the sound-absorbing element (). By configuring the ventilation holes in this manner, hot air can pass unhindered through the holes, while at least a fraction of the light hitting the hole on the optically reflective side of the sound-absorbing element will be prevented from passing through the sound-absorbing element.
