Embodiment Construction

[0041] This aspect will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and to fully convey the knowledge of this aspect to those skilled in the art scope.

[0042] Reference will be made to showing a cross-section of an acoustic lighting tile figure 1 to describe the acoustic lighting tile according to the first embodiment. The acoustic lighting tile 100 includes a cavity 110 having at least one side wall 120 arranged to form an opening in the cavity 110 . The acoustic lighting tile 100 further comprises an acoustic element 130 , at least one light source carrier 140 , at least one light source 150 , at least one reflecting surface 160 and a diffusing element 170 .

Abstract

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.

Description

technical field [0001] The present invention relates generally to the field of acoustically absorbing lighting devices, and in particular to light emitting acoustic tiles (acoustic lighting tiles). Background technique [0002] Sound levels in a room can be reduced by using acoustic absorbing tiles (also called acoustic tiles). Acoustic tiles are typically arranged in a grid system covering the ceiling of the room. In order to illuminate the room from the ceiling, lighting devices may eg be arranged on the outside of the acoustic tiles (ie on the side of the tile facing the room), between the acoustic tiles in the grid or as a replacement for some of the acoustic tiles in the grid dedicated lighting tiles. Since lighting devices typically absorb less sound than similarly sized acoustic tiles, their presence in the ceiling may adversely affect the acoustic properties of the ceiling and may thereby adversely affect the sound level in the room. Therefore, a compromise is typ...
