ACOUSTIC LIGHTING TILE

摘要

An acoustic lighting tile (100) comprises a cavity (110) having a side wall (120) forming an opening in the cavity (110). An acoustic element (130) absorbs sound incident to the cavity (110). A light source carrier (140) is arranged along the side wall (120) and extends a first distance (D1) along a horizontal direction into the cavity (110). A light source (150) is mounted on the light source carrier (140) and emits light (L1, L2, L3) in a vertical main direction into the cavity (110), away from the opening of the cavity (110). A reflective surface (160) reflects at least a subset of the light (L1, L2, L3) emitted by the light source (150) towards the opening. A diffusing element (170) at least partially covers the opening at a second distance (D2) from the light source carrier (140) and diffuses light passing through the opening. The second distance (D2) is at least as large as the first distance (D1). The distance (D2) between the light source carrier (140) and the diffusing element (170) provides a mixing space which facilitates provision of a more uniform illumination.

1. An acoustic lighting tile comprising:
a cavity having a side wall arranged to form an opening in the cavity; an acoustic element adapted to absorb at least a subset of sound incident to the cavity; a light source carrier arranged in the cavity along the side wall, wherein the light source carrier extends a first distance along a horizontal direction into the cavity; a light source mounted on the light source carrier and arranged to emit light in a vertical main direction into the cavity away from the opening of the cavity; a reflective surface arranged in the cavity and adapted to reflect at least a subset of the emitted light towards the opening; and a diffusing element arranged to at least partially cover the opening at a second distance from the light source carrier and adapted to at least partially diffuse light passing through the opening, wherein the second distance is in a direction perpendicular to that of the first distance and at least as large as the first distance.
