Abstract: A lighting system (100) comprising a central lighting device (111), at least one satellite lighting device (121, 131), and a controller (141) for adjusting light settings, is provided. The controller is arranged for transmitting, in response to a user request (140), an association request over a first communication link (142). The central lighting device is arranged for receiving the association request and re-transmitting the association request over a second communication link by means of coded light (112). The satellite lighting device is arranged for transmitting, in response to receiving the association request, its identifier to the central lighting device. The identifier is only transmitted if an association process is enabled. The association process is enabled, in response to a user request, during a limited time period. The central lighting device is further arranged for associating, in response to receiving the identifier, the satellite lighting device with the central lighting device.

Abstract: The present invention relates to alight-emitting panel (1) comprising: a first panel sheet (11), the first panel sheet being optically transparent; a second panel sheet (12); and a cellular support panel (10) sandwiched between the first panel sheet and the second panel sheet. The cellular support panel comprises optically transparent cell walls (13) defining a plurality of tubular channels (14) extending from the first panel sheet towards the second panel sheet. The light-emitting panel (1) further comprises a two-dimensional light-source array (15;16;24;27) comprising a plurality of light-sources (18a-b;19a-b) each being arranged to emit light into at least one of the tubular channels of the cellular support panel. Various embodiments of the present invention provide a cost-efficient light-emitting panel with advantageous light-emission and mechanical properties.

Abstract: In a lighting system, sound levels are detected in the vicinity of at least one lighting unit to determine when there is a sound level above a threshold. The illumination provided by the lighting unit is adapted in such a way as to encourage a reduction of noise generation.

Abstract: An optical acoustic panel 100 for absorbing sound and providing a daylight appearance and a luminaire are provided. The optical acoustic panel 100 comprises a first side 114, a second side 104, a micro perforated foil 110 and a spacing structure 108. The first side 114 receives sound. The second side 104 is opposite the first side 114 and receives light. The micro perforated foil 110 comprises sub-millimeter holes 112, is light transmitting and is arranged at the first side 114. The sub-millimeter holes 112 are entrance holes of a cavity. The spacing structure 108 spaces the first side 114 at a predefined distance from the second side 104. The spacing structure 108 comprises a plurality of light transmitting cells 106.
