Lighting module and lighting kit
Disclosed is a lighting module ( 10 ) comprising a carrier ( 20 ) having a major surface ( 21 ) including a plurality of first regions ( 23 ) and a plurality of second regions ( 25 ), each second region being adjacent to a first region. The lighting module also has a plurality of light engines ( 40 ), each light engine being located in a first region of said carrier, and an optically transmissive light exit structure ( 50 ) facing the major surface and being spatially separated therefrom. Each first region is covered by a separate cover ( 30 ) that is optically transmissive and acoustically reflective. Each cover has a surface portion with a surface normal ( 31 ) under a non-zero angle (θ) with the surface normal ( 51 ) of the light exit structure so that it is shaped to reflect sound waves ( 33 ) towards an adjacent second region ( 25 ). Each second region has an acoustically absorbent member ( 35 ) arranged to absorb said reflected sound waves. Also disclosed is a lighting kit ( 100 ) comprising a plurality of such lighting modules.
1. A lighting module comprising:
a carrier having a major surface; and
an optically transmissive light exit structure facing the major surface and being spatially separated therefrom;
wherein the major surface of the carrier includes a plurality of first regions and a plurality of second regions, the plurality of first regions and the plurality of second regions being arranged in a checkerboard pattern on the major surface, and each second region being adjacent to a first region;
wherein each first region of said carrier has at least one light engine;
wherein each first region is covered by a separate cover that is optically transmissive and acoustically reflective;
wherein each cover has a pyramidal shape comprising a surface portion with a surface normal under a non-zero angle with the surface normal of the light exit structure so that it is shaped to reflect sound waves towards an adjacent second region; and
wherein each second region of said carrier has an acoustically absorbent member arranged to absorb said reflected sound waves.
2. The lighting module of claim 1 , wherein the acoustically absorbent member has a light-reflective coating.
3. The lighting module of claim 1 , wherein the acoustically absorbent member comprises at least one of a foam material, glass wool and a micro-perforated member.
4. The lighting module of claim 1 , wherein the carrier is made of an acoustically absorbent material.
5. The lighting module of claim 1 , wherein each first region comprises an acoustically absorbent recess housing the at least one light engine.
6. The lighting module of claim 5 , wherein the acoustically absorbent recess has a light-reflective inner surface.
7. The lighting module of claim 1 , wherein the light exit structure is a cloth spanning the major surface.
8. A lighting kit comprising a plurality of lighting modules of claim 1 , wherein the lighting modules are configured to be coupled to each other.
9. The lighting kit of claim 8 , further comprising a cloth for spanning across the lighting modules when coupled together in order to obscure said lighting modules from direct view.
