Abstract

The invention relates to a luminaire (1) for illuminating a room (R) and for controlling room acoustics in said room (R). The luminaire (1) comprises: a housing (2) with a cavity (3), a light source (4) arranged in the cavity (3), a rigid transparent cover (5) arranged such that at least part of the light emitted by the light source (4) can be emitted via the cover (5) into the room (R) to be illuminated, a support (6) arranged to support the cover (5), a fastener (7) arranged to fix the cover (5) to the support (6), and a flexible section (8) arranged between the support (6) and the cover (5) and/or between the cover (5) and at least part of the fastener (7) such that the flexible section (8) and the cover (5) are pressed together when the cover (5) is fixed, by the fastener (7), to the support (6). The fastener (7) is arranged to be selectively adjustable between a first position in which the flexible section (8) and the cover (5) are pressed together such that the cover (5) is in a first fixed state in which the cover (5) has a first resonance frequency, and a second position in which the flexible section (8) and the cover (5) are pressed together such that the cover (5) is in a second fixed state in which the cover (5) has a second resonance frequency different from the first resonance frequency. Each of the first and second resonance frequencies is in a range of 300Hz or less.
