Abstract
A luminaire includes a speaker positioned at a first depth within a luminaire housing and capable of generating an audio output from a speaker diaphragm. The luminaire also includes a light source that generates a light output. Further, the luminaire includes a light guide assembly positioned at a second depth within the luminaire housing different from the first depth. The light guide assembly includes an acoustically transparent area positioned along a sound path from the speaker diaphragm, and the light guide assembly extracts the light output from the light source and directs the light output away from the luminaire.
