Abstract:
An acoustic and illuminating ceiling panel includes a layer of acoustic absorbent material, the layer including a main inner face intended to be pointed toward the inside of the room, and light sources on the main inner face that is optionally covered by a voile fabric and/or coated, with a paint, wherein the light sources include organic light-emitting diode (OLED) modules with a luminous efficacy greater than or equal to 60 lm/W, and wherein a number and size of the OLED modules are adapted so that the ceiling panel provides an acoustic absorption coefficient αw greater than or equal to 0.7.
