ACOUSTIC PANEL WITH LIGHTING PROPERTIES Russian patent published in 2017 - IPC E04B1/86 F21V33/00 

FIELD: construction.

SUBSTANCE: acoustic panel comprises one or more long cavities. Each cavity has a first cavity wall, a second cavity wall and a cavity opening between the first cavity wall and the second cavity wall, and the rear end of the cavity. One or more elongated cavity accommodates at the rear end of the cavity a light source having a light emitting surface. The light source is configured to emit a light source that can be emitted from the cavity opening. The first wall of the cavity or the second cavity wall hides the giving off light surface of light source at a time when acoustic panel there is normal to acoustic panel. The acoustic panel also contains sound-attenuating material. The acoustic panel additionally comprises a support frame that holds light sources at the rear end of the cavity. For one or more of the extended cavities, it is provided that the first wall of the cavity and the second wall of the cavity converge on the cone towards the rear end of the cavity and set the angle (γ) of the cavity opening having a value in the range 0°<γ<90°.

EFFECT: invention allows to improve illumination and soundproofing of office premises.
