Definitions
- the present invention relates to a luminaire in connection with a transmission module with antenna for wireless signal transmission.
- Transmitter modules with antennas for wireless signal transmission are known in principle.
- so-called Bluetooth beacons are small signal transmission transmitters, which can be placed as signal generators in the room. These transmit signals at fixed time intervals. If a receiver such as a smartphone with a correspondingly installed application comes within the range of the transmitters placed in this way, the specific transmitter can be identified and its signal strength can be measured. If at least three beacons are within reach of the smartphone, trilateration can be used to calculate the position of the receiver in two-dimensional space, for example. To determine the location in a three-dimensional space, four beacons within range are required. Alternatively, it is also conceivable to place a kind of grid (grid) over the room surface. Field strength information is then initially measured at defined positions of this grid.
- grid grid
- the present invention relates to a luminaire with a luminous module comprising at least one planar printed circuit board with lighting means, a support for receiving the printed circuit boards, a lamp cover which defines a lamp space with the carrier in which the light module is arranged and radiates, and a Transmitter module with an antenna for wireless signal transmission.
- the transmitter module is arranged laterally (preferably on the front side) adjacent to the printed circuit board such that the antenna is placed with respect to the printed circuit boards on the side facing away from the carrier and in the luminaire room.
- the light module has at least two adjacent flat printed circuit boards with light sources, wherein the transmission module is arranged laterally (preferably frontally) to at least one of the circuit boards (ie, at the end of a row of boards) and preferably between the or two adjacent circuit boards, that the Antenna with respect to the printed circuit boards is placed on the side facing away from the carrier and in the luminaire space.
- “Laterally” in the context of the invention means laterally displaced in particular with regard to the surface extension or in the plane of the luminous module or the printed circuit board. that a plurality of transmission modules are provided, wherein these are respectively provided correspondingly between two adjacent printed circuit boards or at least laterally adjacent to a printed circuit board.
- the present invention further relates to a luminaire having a luminous module comprising at least one planar printed circuit board with lighting means, a support for receiving the printed circuit board, a lamp cover which defines a lighting space with the support in which the light module is arranged and radiates, and a transmitter module with an antenna for wireless signal transmission.

- the corresponding transmitter modules of one or more luminaires according to the invention can emit a signal during assembly of the luminaire (s) and for commissioning of the overall system, which in particular includes a number identifying the luminaire or the transmission module .
- a receiving device such as a smartphone or the like
- the signals of the transmission module different lights can be detected. If the room or the building complex is systematically crossed, the system can determine the position of the luminaires on the basis of the received signals and assign them, for example, suitable operating addresses or the like. These can then be deposited, for example, finally in a central controller.
- Another possibility of using the transmission module - in particular in a design of a Bluetooth beacon - is that at a later time, to which the position of the lights is known that signal of the transmission module for indoor localization of devices (such as smartphones) is used ,
- the luminaire according to the first aspect of the present invention is characterized in particular in that the transmitter module is preferably positioned on the carrier or carrier profile of the luminaire, which also carries the luminous modules; in such a way that the lighting modules (such as LED boards) are formed shortened or spaced apart, so that between these two adjacent circuit boards, a (small) gap is formed, in which the transmission module for good transmission of signals on the one hand while low influence of the light radiated light on the other hand can be positioned.
- the lighting modules such as LED boards
- the transmission module for example, on the support or the circuit board is arranged such that it is preferably placed outside of the main emission of the lamp.

- the transmission module can be inserted or pushed into it.
- the transmission module is preferably fastened to a fastening section on or in the fastening region.

- at least the antenna section may be angled.
- the transmitter module is thus preferably angled, so that the antenna, which is preferably provided in an exposed end region of the transmitter module, is placed in the luminaire room in such a way as to enable a sufficiently good signal transmission and at the same time to influence the light output of the luminaire as little as possible.
- the antenna can furthermore be aligned in the direction of the main emission direction of the luminaire, with the antenna section preferably extending parallel to the main emission direction of the luminaire.
- a luminaire can be provided in which the antenna provided for wireless signal transmission is positioned as far as possible at a position in which it can enable the best signal transmission.

- the antenna is thus placed as effectively as possible for signal transmission, with a view to a slight influence on the light output of the luminaire.
- the transmission module and in particular preferably at least the antenna section may have a light-reflecting surface. This may, for example, have a white or white-scattering coating. In this way, any shadowing of the radiated light can be counteracted, since the antenna generally projects beyond the bulbs into the luminaire space.

- the component section is located (at least partially) at the end of the transmitter module opposite the antenna.
- the transmitter module is arranged in a plan view of the lamp centered or laterally of the lamp. With several transmitter modules per lamp, it is also conceivable, a distributed arrangement - preferably evenly distributed arrangement - to provide the transmitter modules to allow a preferred signal transmission.
- the transmission module may further comprise connection lines, which are coupled to a driver of the luminaire and / or an external power source and / or a data line of the luminaire. These preferably extend away from the component section and thus preferably on the back side of the printed circuit boards or of the carrier with respect to the main emission direction of the luminaire.
- the lamp may further comprise an optical element which is arranged in the luminaire space at least partially in the emission direction of the luminous means and preferably together with the carrier defines a blasting chamber.
- This optical element can have light-influencing properties in which, for example, it effects a defined or scattering light-directing and / or has light-converting properties.
- the transmission module can be arranged inside or outside of the blasting room.
- the light cover may be at least partially translucent and preferably transparent. This configuration is particularly preferably provided at least in the main emission direction of the luminaire. If a secondary light output is desired, as an alternative or in addition to a corresponding embodiment in the main emission direction, another region of the luminaire cover can be designed to be translucent accordingly. The light can then reach these areas by means of the optical element or other light influencing elements (for example reflectors). In a preferred embodiment, it is also conceivable that the luminaire can emit light over its entire outer circumference. Even for such an embodiment, it is achieved with the present invention that the antenna module or the antenna of the transmission module as little as possible affects the light output, while it / is simultaneously placed to sufficiently satisfactory signal output.
