Abstract
A sound absorbing luminaire providing lighting for an interior space environment and managing the acoustics within the environment. The luminaire includes a frame holding an acoustic film and a lighting element, forming a resonant cavity between them. The acoustic film is used for absorbing sound within the resonant cavity, and the lighting element provides light from a light source, such as LEDs, through the acoustic film. An optical film can be mounted in the frame between the acoustic film and the lighting element for providing a desired distribution of light.
