Abstract:
There is provided a light-emitting acoustic panel that may be mounted in a ceiling. The light-emitting acoustic panel comprises a sound-absorbing layer and a light-transmissive layer arranged in parallel such that a space is formed in-between. In the space a light source and a reflector are arranged such that light emitted by the light source is redirected by the reflector and emitted towards a reflective side of the sound-absorbing layer. There is further a duct arranged through the light-emitting acoustic panel. In the duct, devices providing functionalities such as sensing, sound, lighting may be arranged. The outer surface of the duct, facing the space between the sound-absorbing layer and the light-transmissive layer comprises a specularly reflective surface.
