Description
Technical Field
[0001] The various examples disclosed herein generally relate to luminaires. Specifically, the various examples disclosed herein relate to wireless communication modules in luminaires, particularly near field communication (NFC) modules. Background Technology
[0002] Traditional solutions for implementing wireless near-field communication in lighting products have limitations due to antenna size and sensitivity to high-permeability materials. This can lead to poor wireless communication performance. Furthermore, high-IP-rating products with metal housings may also present challenges due to high permeability. These limitations make traditional solutions less efficient and less flexible in implementing near-field wireless functionality in lighting products. Summary of the Invention
[0003] Therefore, there is a need for advanced technologies for wireless communication in luminaires that can mitigate or alleviate at least some of the limitations and disadvantages identified above.
[0004] The features of the independent claim satisfy this need. The features of the dependent claim define other advantageous examples.
[0005] The following description of the solutions according to this disclosure relates to the claimed luminaire and the claimed method for assembling and manufacturing the luminaire, wherein features, advantages, or alternative embodiments may be assigned to other claims and vice versa. In other words, the claims relating to the luminaire can be improved with features described in the context of the method, and the method can be improved with features described in the context of the luminaire.
[0006] A luminaire is provided, comprising a housing having an opening. The housing surrounds an interior; in other words, the opening corresponds to an orifice between the exterior and interior of the luminaire, through which the interior of the housing can be accessed from the exterior. In other words, the opening or orifice extends from the exterior to the interior, or connects the interior and exterior, or extends through the housing. The luminaire also includes a display having at least a front surface and a rear surface, the display being positioned within the opening such that the front surface of the display is visible in the viewing direction when a user views the luminaire from outside the housing. Typically, the housing includes the display, wherein the display is arranged within and fixed within the opening of the housing, wherein additionally, an antenna of a wireless communication module is also arranged within or behind the opening, specifically behind the display in the viewing direction, i.e., the area of the antenna overlaps with the interior area of the opening (defined by the opening) and / or the display within the opening.
[0007] In various examples, a luminaire housing may sometimes be referred to as a shell or enclosure designed to house and protect the internal components of the luminaire. In various examples, the housing may include additional functional entities, such as user interface modules or connector modules. An opening in the display (sometimes referred to as a display assembly aperture) allows the display to be assembled within the housing. Depending on the intended use and aesthetic preferences, the housing can be designed in various shapes and sizes. The opening in the housing allows the display to be assembled within the housing with a certain level of protection (IP), thus also providing IP protection for wireless communication modules (particularly the antenna of the communication module behind the display). The interior of the luminaire housing (which may also be referred to as the internal space) is the space inside the housing that houses the components of the luminaire. The housing allows access to the interior, enabling the installation, repair, or replacement of components as needed.
[0008] In various examples, a display can be any electronic screen or panel that presents information, images, or graphics to a user. The front surface (also called the viewing surface or face) is the portion of the display visible to the user. Alternative terms for display may include screen, monitor, or interface. Displays can be of different types, such as, for example, LED, OLED, or LCD, and can be used to present information, graphics, or images to a user. The antenna of a wireless communication module can be designed for various wireless communication technologies, such as Wi-Fi, Bluetooth, RFID, or NFC, and can be positioned near the display, particularly behind the display, to improve signal reception and transmission. Therefore, the communication signals of the communication module or system traverse the display area.
[0009] In various examples, the viewing direction can correspond to a line of sight, where the front surface of the display is visible through the opening when the user looks at the light fixture from outside the housing. In this context, the user's perspective or viewpoint is taken into account. When the user observes the light fixture from an external position, the front surface of the display can be seen through the opening in the housing in the viewing direction. Typically, the viewing direction can refer to any direction or axis from the outside of the light fixture through the opening to the inside of the light fixture. For example, the viewing direction can be described as a direction perpendicular to the surface plane of the display, or a direction along an axis passing through the opening from the outside of the housing to the inside.
[0010] There are various methods and options available for placing an antenna behind a display within a lighting fixture. In various examples, the antenna of the wireless communication module is positioned behind the display in the viewing direction. The antenna (which can also be called a wireless signal receiver and transmitter) is the component in the wireless communication module that enables the transmission and reception of wireless signals. Placing the antenna behind the display in the viewing direction means that the antenna is located on the opposite side of the display relative to the user's viewing angle, ensuring that it can transmit through an opening but is not visible to the user.
[0011] In some examples, the area behind the display may correspond to an arrangement where the antenna and display completely or partially overlap. Typically, one or more areas of the opening, display, and antenna may partially or completely overlap. For example, the projections of these areas onto a plane perpendicular to the direction or axis extending through the opening may completely or at least partially overlap. In other words, depending on the desired design and function, the antenna may be positioned behind the display to partially or completely overlap with it.
[0012] In other words, the antenna and display components can have spatial overlap, meaning that when projected onto a plane orthogonal to the observer's line of sight, the areas they occupy coincide. The display and antenna are positioned sequentially along the same axis, which intersects both and is typically perpendicular to the observation direction. The display is the first component the observer encounters, while the antenna is located directly behind it and therefore not visible to the observer. The display and antenna are stacked along the same axis.
[0013] In this regard, the antenna extending along the rear display surface can provide sufficient signal reception and transmission while reducing the overall complexity of the luminaire.
[0014] The antenna can be positioned on a plane parallel to the display (in other words, parallel to the area defined by the opening (the opening edge)). This helps optimize antenna performance and maintain a compact design. In some examples, the antenna can be positioned at an angle to the display. In some cases, the antenna can be configured to have the same size as the display to ensure seamless integration of the components. Alternatively, the antenna can be designed to be larger or smaller than the display, depending on the specific requirements of the wireless communication module and the available space within the lamp housing.
[0015] The antenna can be centered or concentrically arranged, aligned with the center of the display, to maintain a balanced appearance and functionality. However, if certain design constraints or requirements necessitate such an arrangement, it can also be located outside the center or in an asymmetrical position, or at an angle to the opening.
[0016] In various examples, the antenna behind the display is arranged inside the housing, specifically adjacent to the rear surface of the display (e.g., the rear surface of the backlight module), and thus also located within or behind an opening within a lamp fixture. The region of the antenna can be arranged such that, along an axis or direction extending through the opening, the region of the antenna is positioned behind the opening, in other words, at least partially overlapping with and / or extending along the opening. Thus, the transmission direction of the antenna can be through the display and through the opening.
[0017] These different options for placing antennas behind the display provide flexibility in the design of the lighting fixtures, which can meet various aesthetic preferences, functional requirements and space constraints, while ensuring effective wireless communication capabilities.
[0018] The provided technology addresses the challenges associated with NFC antenna placement in lighting products. By positioning the NFC antenna behind the user interface display, the invention overcomes the limitations related to available space, material permeability, and design constraints in compact and high IP-rated luminaires. This configuration effectively solves the technical problem of finding a suitable NFC antenna location that does not negatively impact antenna performance or interfere with luminaire design. By placing the NFC antenna behind the display, the invention fully utilizes the available surface area allocated to the display on the luminaire's user interface. This method ensures that the NFC antenna does not occupy additional space and requires no special mechanical treatment, as the display always has a clear view on the lighting product. Furthermore, placing the NFC antenna behind the display does not significantly affect the NFC antenna's magnetic field, allowing the magnetic field to couple through the display and reach the front of the unit. Therefore, users can interact with the luminaire's user interface using NFC-enabled mobile devices to exchange data. Thus, placing the NFC antenna within the luminaire maximizes available space without interfering with antenna performance or luminaire design, and allows for seamless interaction between the luminaire and NFC-enabled devices.
[0019] The corresponding method for assembling the luminaire includes: providing a housing with an opening; providing a display with a front surface; providing a wireless communication module; and assembling the display and the wireless communication module inside the housing. When a user observes the luminaire from outside the housing, the front surface of the display can be seen through the opening, and the antenna of the wireless communication module is arranged behind the display in the direction of observation.
[0020] The assembly process can involve a variety of techniques and tools, depending on the specific design and components of the luminaire. This may include securing the display and antenna to the housing using screws, adhesives, press fits, or other fastening methods. Furthermore, the assembly process involves electrically coupling various components, such as the control PCB, FPC connectors, and wireless communication modules, to ensure the proper functioning and operation of the luminaire.
[0021] The method can be further modified to assemble any of the luminaires described in this disclosure.
[0022] It should be understood that, without departing from the scope of this disclosure, the features mentioned above and those to be explained below may be used not only in the corresponding combinations indicated, but also in other combinations or individually. Specifically, without departing from the scope of this disclosure, the features mentioned above and those to be explained below may be used not only in the corresponding combinations indicated, but also in other combinations or individually.

[0023] Those skilled in the art will recognize and understand these and other objects of the invention from the detailed description of the preferred embodiments and the following drawings, in which similar reference numerals refer to similar elements.

[0028] Figure 5 The steps of a method for assembling a luminaire are illustrated schematically according to various examples. Detailed Implementation
[0029] In the following description, embodiments of the invention will be illustrated in detail with reference to the accompanying drawings. It should be understood that the following description of the embodiments should not be considered limiting. The scope of the invention is not intended to be limited by the embodiments or drawings described below, which should be considered as illustrative examples of a general inventive concept. Unless otherwise specifically indicated, features of various embodiments may be combined with each other.
[0030] The accompanying drawings should be considered schematic representations, and the elements shown in the drawings are not necessarily shown to scale. Rather, the various elements are shown such that their function and general purpose will be obvious to those skilled in the art. Any connection or linkage between functional blocks, devices, elements, or other physical or functional units shown in the drawings or described herein may also be achieved through indirect connections or linkages.
[0031] The following describes a technique involving the use of existing surface areas of a display included in the housing of a luminaire to enable wireless communication of the luminaire more efficiently and flexibly.
[0032] Traditional solutions for implementing wireless communication in lighting products have limitations due to antenna size and sensitivity to high-permeability materials. This can lead to poor wireless communication performance or even complete failure. Furthermore, high-IP-rating products with metal casings also pose challenges to wireless communication signals. These limitations make traditional solutions less efficient and less flexible in implementing NFC functionality in lighting products.
[0033] Enabling NFC in lighting products can be challenging due to the need to find suitable locations for NFC antennas. NFC antennas must be sized to achieve optimal coupling distance with NFC-enabled mobile devices. NFC antennas should not be placed behind materials with high magnetic permeability, as this will prevent magnetic fields from reaching the antenna from the NFC-enabled device. It's best to avoid placing NFC antennas near materials with high magnetic permeability, as this can negatively impact antenna performance. This limits the possibilities for placement that avoids interference with the antenna. For example, in moving head lights, the available space for user interface components is often limited because cable connections, menu buttons, and displays are located on the same side of the base. This is especially true for moving head lights with compact base designs. For high IP-rated products with metal housings, placement can be a significant challenge, as it requires the housing surface to be free of materials with high magnetic permeability.
[0034] According to the present invention, the surface area already allocated to the display on the user interface of the lighting fixture is used. Therefore, the NFC antenna does not occupy more space and requires no special mechanical treatment, since the display always has a clear view on the lighting product.
[0035] Figure 1 The luminaire 10 is illustrated schematically according to various examples.
[0036] exist Figure 1 The image shows an overview of a moving head light 10. The light 10 includes a base 14 and a moving head 13. The base 14 of the light 10 includes a user interface module 100 with a display 110. Within the base 14 and the user interface module 100, the housing 11 of the light 10 includes an opening 12 in which the display 110 is arranged and sealed.
[0037] The assembly of the display 110 and the housing 11 has an IP rating that prevents solid objects and water from entering the housing 11.
[0038] The lamp 10 also includes a wireless communication module ( Figure 1 (Not shown), particularly wireless communication modules (or transceivers) for short-range communication, especially active or passive components for wireless (short-range) communication systems. For example, such passive components may be referred to as contactless identification elements or wireless identification elements, encompassing a series of passive elements that store information and respond to signals from active devices in a contactless communication system. Wireless communication modules may be, for example, near-field communication (NFC) tags or radio frequency identification (RFID) tags. The arrangement of components within the lamp housing will be described in further detail below. Antenna 121 is arranged in an opening behind the display, as will be described in further detail below.
[0039] Figure 2 The illustrations are based on various examples, including... Figure 1 The user interface 100 of the lamp 10 has a display 110.
[0040] Figure 2 A front view of the user interface module 100 is shown, illustrating a display 110 and its front surface 111. The display 110 is located inside the housing 11 such that the front surface 111 is visible through the opening 12 in the viewing direction when the user of the luminaire 10 views the luminaire 10 from outside the housing 11. The user interface module is assembled into the luminaire housing 11, which in this respect can be referred to as part of the housing 11, and the opening 12 for the display 110 is provided therein.
[0041] In various examples, the magnetic coupling of the standard display 110 does not significantly affect the magnetic field of the NFC antenna, so the NFC antenna can be additionally arranged behind the display 110 within the opening 12. Therefore, one or more NFC antennas can be placed on the back of the user interface display 110 in the lamp 10. This allows the magnetic field to couple through the display and outward through the lamp housing to the front of the unit. Thus, NFC-enabled mobile devices can interact with the user interface of the lamp 10 to exchange data.
[0042] Figure 3 The illustrations are based on various examples. Figure 2 A top view of the user interface 100.
[0043] exist Figure 3 The image shows the back of the user interface module 100 as seen from the inside of the lamp towards the outside, where the NFC antenna 121 of the wireless communication module 120 can be seen. The NFC antenna 121 covers the area of the opening 12 and the rear surface of the display.
[0044] The display is located within opening 12, allowing the user of the luminaire 10 to see the front surface through opening 12 in the viewing direction when viewing the luminaire 10 from outside the housing 11. In this example, the display is sealed within the opening and provides an IP rating for the luminaire. The NFC antenna 121 of the wireless communication module is arranged in a stacked configuration with the control PCB and the display, as combined... Figure 4 Further described. The wireless communication module may include multiple components, which may include an antenna, a control circuit system, and connectors to additional components on a separate control PCB or arranged on a PCB assembly of the user interface 100.
[0045] It can be seen that the NFC antenna 121 extends at least partially parallel to the area of the opening and the display.
[0046] The NFC antenna 121 is manufactured as a flexible printed circuit board (FPC) and bonded to the rear surface of the display 110, allowing for a simple, flexible connection to user interface PCB assemblies typically used in display components. It can also be FR4-based with standard board-to-board connectors. The antenna 121 has adhesive on its back side for secure attachment to the back of the display 110.
[0047] Figure 4 The illustrations are based on various examples. Figure 2 A cross-sectional view of the user interface 100.
[0048] exist Figure 4 The image shows a cross-sectional view of the display 110 and the antenna 121, showing the antenna 121 and the rear surface of the display 110 arranged directly adjacent to each other. A flexible connector 122 to the control PCB of the user interface 100 is also shown. The antenna 121 is positioned behind the display 110 in the viewing direction.
[0049] Antenna 121 is bonded to the backlight module of display 110. Antenna 121 is electrically coupled to a control PCB within housing 11 via a flexible printed circuit (FPC) connector 122, and is mechanically separated from the PCB via the FPC. The control PCB is arranged substantially parallel to antenna 121 and spaced a predetermined distance from antenna 121. For example, the control PCB and antenna 121 may be arranged at a distance along the viewing direction, or perpendicular to each other.
[0050] from Figure 4 As can be seen, the control PCB (i.e., the PCB assembly of the user interface module 100) is arranged in parallel with the display 110 and the antenna 121, and is separated from the antenna by an air gap bridged by a flexible connector (122).
[0051] Figure 5 The steps of a method for assembling a lamp 10 according to various examples are illustrated schematically.
[0052] The method begins at step S10. In step S20, a housing for the luminaire is provided, the housing including an opening through which access to the interior of the housing is made. In step S30, a display having a front surface is provided. In step S40, a wireless communication module is provided. In step S50, the display and the wireless communication module are assembled inside the housing, optionally partially within or extending through the metal housing, wherein the front surface of the display is visible in the viewing direction through the opening when the user of the luminaire views the luminaire from outside the housing, and the antenna of the wireless communication module is arranged behind the display in the viewing direction. The method ends at step S60.
[0053] Based on the above, the following general conclusions can be drawn:
[0054] The antenna can extend at least partially parallel to the display. This antenna arrangement can improve signal reception and transmission by increasing the effective surface area for wireless communication. The antenna can be designed in various shapes and sizes and can be made of a variety of materials, such as copper or other conductive materials.
[0055] The luminaire may include a base and a head movable relative to the base, wherein a display and a wireless communication module are arranged within the base. Including a movable head provides greater flexibility in guiding light output, allowing for adjustment of the luminaire's focus as needed. The base houses the display and wireless communication module, enabling a compact design and protecting components from external damage.
[0056] The antenna can be positioned directly adjacent to the rear surface of the display in the viewing direction. Positioning the antenna close to the rear surface of the display reduces the overall thickness of the luminaire and improves signal reception and transmission performance. This arrangement also helps minimize interference between the display and the antenna.
[0057] The assembly of the display and housing can have an IP (Infrared) rating to prevent the ingress of solid objects and water. An IP rating ensures the luminaire is protected from solid objects such as dust or debris and water, thus enhancing its durability and making it suitable for various indoor and outdoor environments. A specific IP rating can be selected based on the intended use and the required level of protection.
[0058] The wireless communication module may include a wireless communication module for short-range communication. Short-range communication enables communication with nearby devices (such as smartphones or tablets) for control or data transmission purposes. The module may support various short-range communication technologies.
[0059] Typically, short-range communication systems (such as Near Field Communication (NFC) or Radio Frequency Identification (RFID) systems) are wireless communication technologies that enable identification, tracking, and data exchange between active components (such as transceivers or readers) and passive components (i.e., NFC / RFID tags) over short distances using radio waves.
[0060] In an NFC / RFID system, an active component (transceiver / reader) sends signals to a passive component (tag). The tag, storing information, responds by transmitting its stored data back to the active component. The active component then processes the received data for various applications, such as inventory management, access control, or control purposes. RFID systems can operate at various distances and frequencies, making them suitable for a wide range of applications, including supply chain management, asset tracking, and transportation.
[0061] Wireless communication modules may include Near Field Communication (NFC) tags. Including NFC tags enables contactless communication with compatible devices, facilitating pairing, data transfer, or control functions. This provides users with additional convenience and functionality. Typically, tags for contactless communication systems can refer to passive components of the contactless (wireless) communication system and may include antennas and control circuitry (such as integrated circuits).
[0062] The wireless communication module may include radio frequency identification (RFID) tags. RFID tags enable luminaires to communicate with or use RFID transceivers or devices, thereby achieving the purpose of identifying, tracking, or controlling specific luminaires. This function is particularly useful in commercial or industrial applications.
[0063] In a typical wireless communication module, an NFC / RFID tag may contain an integrated circuit (IC) and an antenna, which work together to facilitate wireless communication with an active reader or transceiver. The IC (also known as a control circuitry or microchip) is responsible for processing and storing information, while the antenna enables the tag to receive and transmit signals. The antenna can be arranged such that most of its area is located within an opening, in other words, behind the display and / or opening of the housing. In some examples, the overlap between the antenna and the opening and / or display can be greater than 20%, or 40%, or 60%, or 80%, or 90%, or equal to 100% (i.e., the entire antenna area is positioned within the opening and behind the display). And the IC can be arranged behind the display / opening in the same manner as the antenna.
[0064] In a typical NFC / RFID tag, the control circuitry is embedded in the tag's substrate, which can be made of various materials such as paper, plastic, or even metal. The antenna, typically made of conductive materials like copper or aluminum, is attached to the IC via direct attachment or the use of conductive adhesive. Depending on the required operating frequency, range, and application, the antenna can take on various shapes and configurations.
[0065] Passive NFC / RFID tags operate by harnessing energy from the electromagnetic field generated by an active reader or transceiver. When a tag approaches a reader, the antenna captures the energy from the reader's radio waves and uses it to power the IC. The IC then modulates the electromagnetic field to transmit the stored data back to the reader, enabling wireless identification, tracking, and data exchange.
[0066] In the context of FPC (Flexible Printed Circuit), passive contactless identification elements (such as NFC / RFID tags) can be integrated into flexible circuit systems to enable wireless communication with active readers or transceivers. FPC provides a thin, lightweight, and flexible substrate for control circuit systems and antennas, making it suitable for space-constrained or mechanically dynamic applications.
[0067] The control circuitry system, or integrated circuit (IC), is mounted on a flexible polymer substrate, typically made of materials such as polyimide. The IC is responsible for processing and storing information, and it can be connected to other electronic components on the FPC using conductive traces.
[0068] The antenna that enables the tag to receive and transmit signals is also integrated into the FPC. It can be manufactured using conductive materials such as copper or silver, and patterned onto a flexible substrate using various techniques such as etching or screen printing. The antenna design is influenced by factors such as operating frequency, range, and application requirements.
[0069] When an FPC-based NFC / RFID tag approaches an active reader or transceiver, the antenna captures energy from the reader's radio waves and uses it to power the control circuitry. The IC then processes the input signal and modulates the electromagnetic field to transmit the stored data back to the reader.
[0070] The antenna can make direct contact with the display's backlight module. By placing the antenna in direct contact with the backlight module, the thickness of the lamp can be further reduced, and signal reception and transmission performance can potentially be improved. This arrangement also helps with heat dissipation from the backlight module.
[0071] The antenna can be connected to the control printed circuit board (PCB) inside the housing via a flexible printed circuit (FPC) connector. This connection method allows for greater flexibility in the positioning of the antenna and control PCB within the housing. FPC connectors can be designed in various lengths and configurations, providing versatility for the assembly and layout of lighting components.
[0072] The control PCB can be arranged substantially parallel to the antenna and spaced a predetermined distance from it. This arrangement helps minimize interference between the control PCB and the antenna while also providing a compact design. The predetermined distance can be determined based on the specific requirements of the lighting fixture and the wireless communication module.
[0073] The antenna can be implemented as a flexible printed circuit board (FPC). Using an FPC as an antenna allows for flexible, lightweight design and easy integration into the luminaire housing. This also enables the antenna to adapt to various shapes and sizes, providing versatility for the overall design of the luminaire.
[0074] The antenna can be implemented as a printed circuit board (PCB). PCB-based antenna designs can provide a more robust and durable structure, which is beneficial in certain applications or environments. PCBs can be designed in various shapes and sizes to suit the specific requirements of lighting fixtures and wireless communication modules.
[0075] The antenna can be glued to the back surface of the display. Using adhesive to attach the antenna to the back surface of the display can further reduce the overall thickness of the fixture and potentially improve signal reception and transmission performance. This attachment method also simplifies the assembly process and reduces the need for additional fasteners or connectors.
[0076] It should be understood that the described technologies have been described with regard to user interface panels assembled in luminaires including displays; however, it is clear that they can be used not only with user interface panels but also with any display of the luminaire. It is even possible that the light-emitting openings of the luminaire can replace the display for wireless communication. Furthermore, any communication module and / or antenna can be used based on any communication standard, thus allowing its assembly within luminaires with improved connectivity.
[0077] Although the disclosed technology has been described with respect to certain preferred embodiments, equivalents and modifications will occur to those skilled in the art upon reading and understanding the specification. This disclosure includes all such equivalents and modifications and is limited only by the scope of the claims.
[0078] To illustrate, the above has disclosed various scenarios related to lighting fixtures, and similar technologies can be applied to any other packaged electronic device.
