Acoustic luminaires
A luminaire can include a power source housing that houses at least one light fixture component. The luminaire can also include a light engine tray disposed proximate to the power source housing. The luminaire further can include a first acoustic feature coupled to the power source housing and the light engine tray, where the first acoustic feature comprises a first side wall having a first configuration, where the first configuration of the first side wall absorbs sound.
1. A luminaire comprising:
a power source housing that houses at least one light fixture component;
a light engine tray disposed proximate to the power source housing;
an air chamber disposed, at least in part, between the power source housing and the light engine tray; and
a plurality of acoustic features comprising a first side wall and a first baffle, wherein the first side wall and the first baffle absorb sound, wherein the first baffle is disposed within the air chamber, wherein the first baffle divides the air chamber into multiple portions, and wherein the first side wall is coupled to the power source housing and the light engine tray,
wherein the first side wall, the power source housing, and the light engine tray form the air chamber.
2. The luminaire of claim 1 , wherein the plurality of acoustic features comprises compressed polyethylene terephthalate.
3. The luminaire of claim 1 , wherein the first baffle is non-planar.
4. The luminaire of claim 1 , wherein the first side wall has a non-parallel orientation relative to an adjacent side of the power source housing.
5. The luminaire of claim 1 , wherein the plurality of acoustic features further comprises a plurality of extensions that extend from the first side wall.
6. The luminaire of claim 1 , wherein the plurality of acoustic features further comprises a second side wall coupled to the power source housing, wherein the second side wall is opposite the first side wall with respect to the power source housing, wherein the second side wall further forms the air chamber.
7. The luminaire of claim 1 , wherein the plurality of acoustic features further comprises an adjacent wall coupled to the power source housing, wherein the adjacent wall is adjacent to the first side wall.
8. The luminaire of claim 1 , wherein the air chamber is filled, at least in part, with a material that comprises at least one of a group consisting of fiberglass, wool, and cork.
9. The luminaire of claim 1 , wherein the air chamber is open-ended.
10. The luminaire of claim 1 , wherein at least part of the first side wall is adjustable by a user.
11. The luminaire of claim 1 , wherein the first baffle is oriented in parallel with the first side wall.
12. The luminaire of claim 11 , wherein the first baffle has a first length that is less than a second length of the first side wall.
13. The luminaire of claim 1 , wherein the first baffle is coupled to the power source housing and the light engine tray.
14. The luminaire of claim 1 , wherein the plurality of acoustic features further comprises a second baffle disposed within the air chamber.
15. The luminaire of claim 1 , wherein the plurality of acoustic features further comprises an additional first side wall that forms an air chamber with the first side wall.
16. A luminaire comprising:
a power source housing that houses at least one light fixture component;
a light engine tray disposed proximate to the power source housing;
a first side wall coupled directly to the power source housing and the light engine tray on a first side, wherein the first side wall absorbs sound, and wherein the first side wall has a first outer side surface;
a second side wall coupled directly to the power source housing and the light engine tray on a second side opposite the first side, wherein the second side wall absorbs sound, and wherein the second side wall has a second outer side surface; and
an air chamber disposed, at least in part, between the power source housing, the first side wall, the second side wall, and the light engine tray,
wherein the first outer side surface of the first side wall and the second outer side surface of the second side wall, when viewed cross-sectionally along their length, are antiparallel with respect to each other, and
wherein the power source housing and the light engine tray avoid direct physical contact with each other.
17. The luminaire of claim 16 , wherein the first side wall and the second side wall are symmetrical with respect to each other along a vertical axis when viewed cross-sectionally along their length.
18. The luminaire of claim 16 , wherein the first side wall comprises a base and a plurality of protrusions that extend outward from the base, and wherein the base is coupled to the power source housing and the light engine tray.
19. The luminaire of claim 16 , wherein the first outer surface of the first side wall is anti-planar.
20. The luminaire of claim 16 , wherein the first side wall has a thickness that varies along its height.
