摘要： An acoustic lighting tile (100) comprises a cavity (110) having a side wall (120) forming an opening in the cavity (110). An acoustic element (130) absorbs sound incident to the cavity (110). A light source carrier (140) is arranged along the side wall (120) and extends a first distance (D1) along a horizontal direction into the cavity (110). A light source (150) is mounted on the Slight source carrier (140) and emits light (L1, L2, L3) in a vertical main direction into the cavity (110), away from the opening of the cavity (110). A reflective surface (160) reflects at least a subset of the light (L1, L2, L3) emitted by the light source (150) towards the opening. A diffusing element (170) at least partially covers the opening at a second distance (D2) from the light source carrier (140) and diffuses light passing through the opening. The second distance (D2) is at least as large as the first distance (D1). The distance (D2) between the light source carrier (140) and the diffusing element (170) provides a mixing space which facilitates provision of a more uniform illumination.

摘要： A lighting panel comprises a light source and a light modifying panel positioned over the light source, in the form of a set of protrusions over the base, the protrusions facing the light source. The protrusions comprise circular/elliptical/polygonal cylinders or cone sections with a small cone taper angle.

摘要： A space control system and a detection system are disclosed. The detection system is configured for distinguishing a moving living object, e.g. a human being, from a moving machine object in a space. The system comprises an imaging apparatus configured for producing a plurality of images over time of at least a part of the space. The images have a good spatial resolution. The system also comprises a processor configured for determining motion signals of the moving living object and the moving machine object from the plurality of images. The processor is configured to transform the motion signals to a frequency domain and distinguish in the frequency domain between motion signals related to moving living objects and motion signals related to the moving machine objects. Accordingly, the system is enabled to detect at least one of the living object and the machine object in the part of the space on the basis of the distinguished motion signals.

摘要： A lighting device comprising: a first radio transceiver for connection to at least one further lighting device via a first wireless network; a second radio transceiver for connection to a network device via a second wireless network; a memory storing credentials assigned for use by the second transceiver for communication with the network device; and a control module configured to: detect that the lighting device is to operate as a bridge, instead of a further lighting device, to allow data to be exchanged between the at least one further lighting device and the network device; obtain credentials that have been established for use by the further lighting device to communicate with the second network; and modify the credentials stored in memory such that the credentials associated with the further lighting device are assigned for use by the second transceiver, thereby configuring the lighting device to operate as the bridge.

摘要： An apparatus (200, 300, 400, 500) includes a lighting driver circuit (210, 310, 410, 510) and a housing (220, 420, 520) in which the lighting driver circuit is disposed. The lighting driver circuit is configured to receive an input voltage (10) between a pair of input terminals (305) and in response thereto to supply power to one or more light sources (20). The housing has an electrically insulating inner surface (222, 422, 522) and an electrically insulating outer surface (228, 428, 528) and an electrically conductive electromagnetic shield layer (226, 426, 526). The electrically conductive electromagnetic shield layer is disposed between the electrically insulating inner surface and the outer electrically insulating surface. The lighting driver circuit is electrically connected to the electrically conductive electromagnetic shield layer of the housing.

摘要： Methods and apparatus for detection and notification of pressure waves are described herein. A lighting unit (100) may include one or more light sources (104) such as LEDs, a pressure wave sensor (106), a communication interface (108), and a controller (102) operably coupled with the one or more LEDs, the pressure wave sensor, and the communication interface. In various embodiments, the controller may be configured to receive a signal from the pressure wave sensor, the signal representative of one or more pressure waves detected by the pressure wave sensor. The controller may be configured to determine, based on the signal received from the pressure wave sensor, that the detected one or more pressure waves satisfy a predetermined criterion. The controller may be configured to transmit, to one or more remote lighting units via the communication interface, notification that the predetermined criterion has been satisfied.
