Description

Modular wall lamp TECHNICAL SECTOR The present invention relates to a modular wall lamp that has the special feature of allowing the design of the room to be changed with a simple gesture without the need for tools or technical knowledge. More specifically, the lamp of the invention is designed specifically to integrate ornamental materials or pieces, such as stone pieces like marble, combining functionality, aesthetic customization and ease of component exchange. BACKGROUND OF THE INVENTION In the practical application of the invention, although countless models of wall-mounted lamps are known, these are unalterable devices, whose aesthetic modification requires specialized personnel, as well as the use of specific tools. Therefore, the applicant is unaware of the existence of modular wall lamps that allow easy manual customization, simple and without the need for tools, and that simultaneously offer the possibility of connecting wirelessly to electricity, without the need for a rechargeable battery. EXPLANATION OF THE INVENTION The proposed modular wall lamp fully and satisfactorily resolves the aforementioned problem, based on a simple but effective solution. To achieve this, the lamp's overall structure is divided into two main, complementary modules that are manually joined using a tongue-and-groove system, which determines only one possible position between them. Both modules are preferably made of PETG, a strong, durable material suitable for supporting both electronic components and heavy loads, such as natural stone or a similar stone or agglomerated material incorporated into the lamp as an ornamental element. The modular wall lamp of the invention stands out for its hybrid concept between functional lighting and sculptural and decorative piece, including a magnetic fixing system and distributed electronics, which allows the lamp to be used as an interchangeable, adaptable and visually striking art object. More specifically, the first module forms the structural basis of the system and includes a main housing, designed to be mounted to the wall using pre-drilled anchor points. The housing contains a chamber to accommodate the power, control, and communication modules, as well as two contact points for electrical connection to the second module. The first module also includes a cavity to house a magnet, which will hold the second module in place. This first module is in turn preferably divided into three functional zones or levels: The first level houses the aforementioned magnetic fastening system. More specifically, this level defines a cavity containing a high-power neodymium magnet, located in a housing designed for complete stability. This magnet is responsible for the physical connection to the second module, allowing the ornamental piece (such as a stone piece, which may be quite heavy) to be held securely without the need for visible screws. The second or intermediate level includes the electrical power contacts. Here, two aluminum pins are located, which determine the electrical connection to the second module. These pins, preferably made of aluminum, are adjacent to the neodymium magnet in the first level and function as positive and negative contacts, transmitting power to the second module when the two elements are magnetically coupled. The arrangement and tolerance of the two pins ensure a firm, continuous, and lossless connection. Finally, on a third, larger level, closer to the wall, is the compartment where the system's electronic components are integrated (power modules, control and communication electronics). This third level therefore houses the entire electronic system responsible for powering and controlling the lamp. It includes a compact power supply, management circuitry, relays, converters, and the necessary elements to stabilize the current. The design of the first module optionally incorporates a passive ventilation system with strategically placed ventilation channels that allow airflow and prevent overheating, ensuring prolonged and safe performance. The first module is preferably complemented by a removable back cover that conceals the internal control electronics and features a cross-slot designed to accommodate additional interchangeable decorative elements. These additional decorative elements can be made from materials such as brass, aluminum, wood or resins, allowing the lamp's appearance to be adapted to the user's environment. As for the back of this first module, it optionally integrates additional magnets as complementary magnetic elements to the neodymium magnet, intended to attach an optional spacer. This spacer increases the distance between the first module and the wall when required, allowing the user to adjust the depth or the aesthetic tilt of the lamp. The first module is fixed to the wall using four structural screws that are subsequently hidden with magnetic covers, achieving a clean, minimalist finish with no visible elements. As detailed above, in one embodiment of the invention the entire first module includes small side and rear slots or channels that ensure ventilation of the system to prevent heat buildup. The second module consists of an interchangeable piece that the user can attach or remove according to their choice of ornamental piece or design. This second module includes an optical cover, linked to a housing that incorporates a metal counterpiece which acts as a direct receiver for the magnet housed in the first module. This housing also contains two electrical connection pins, complementary to the two pins in the first module. These pins power an LED lighting system that runs around the perimeter of the housing to which the optical cover is attached. This optical cover is made of a translucent material and is integrated onto an ornamental piece. Preferably, the second module is also configured in three levels or sectors, each with a specific function: The first section of the second module has a structure, preferably in the shape of a crescent moon or a right oval, which includes a metal counterpiece that acts as a direct receiver for the neodymium magnet housed in the first module. The thickness of the first section (preferably between 5 and 10 mm) varies according to the diameter and weight of the selected ornamental stone, preferably a piece of stone, which also preferably has a thickness between 20 and 50 mm, thus ensuring a perfectly adapted and secure hold. The middle section of the second module contains two electrical connection pins, preferably made of aluminum, which receive power from the pins of the first module. The pins are designed to withstand repeated use and ensure a safe and stable electrical connection. The third section of the second module contains an LED lighting system and an NFC (Near Field Communication) board. The LEDs are arranged in a circle to generate homogeneous lighting around the ornamental piece. The NFC board allows for electronic communication or automatic activation of the LEDs, depending on the final product configuration. As detailed above, the second module is fixed by four screws (two hidden) to a translucent optical cover, which is responsible for diffusing the lighting homogeneously around the lamp, and which is subsequently attached to the stone piece, whose diameter can vary between 20 cm and 60 cm, with a standard thickness of about 2 cm. The optical cover is attached to a housing, which contains the metal counterpiece that receives the magnet housed in the first module. The housing has two electrical connection pins. These pins are complementary to the pins on the first module, which power the LED lighting system that runs along the housing to which the optical cover is attached. From this structure, the following advantages are derived: Each ornamental piece used is unique, due to the nature of the material employed, which may be stone, characterized by distinct veining, unique tones, and sculptural qualities. This makes each modular wall lamp a singular, almost museum-quality work of art, fusing design, craftsmanship, and technology. The magnetic system and structural modules allow the user to easily remove and replace the ornamental piece (which can be a heavy stone piece), change the second module for another of a different design, updating or replacing ornamental pieces without the need for tools and without the need for batteries. Greater durability and openness to a future catalog of ornamental pieces, such as stone pieces or pieces made of other unique materials, or compatible modules. Interchangeable side decoration: The decorative elements allow you to modify the lamp's appearance without changing the ornamental piece or the lighting system. This expands the possibilities for customization and adaptation to the architectural environment. The system allows users, for a small fee, to send their current decorative piece and receive a different one in return. This model transforms the lamp into a constantly evolving object, more akin to an art collection than a static product. Sculptural and decorative function; the combination of ornamental materials, such as natural, synthetic, or polymer stone, perimeter lighting, and interchangeable modules gives the modular wall lamp an aesthetic character that goes beyond its lighting function. Each lamp acts as a sculptural element with its own presence, suitable for contemporary spaces, galleries, hotels, and high-end design homes. BRIEF DESCRIPTION OF THE DRAWINGS To complement the description that follows and to aid in a better understanding of the characteristics of the invention, according to a preferred embodiment thereof, a set of drawings is included as an integral part of said description, in which, for illustrative and non-limiting purposes, the following has been represented: Figure 1 shows a side-front perspective view of the first module, which is part of a modular wall lamp made in accordance with the object of the present invention. Figure 2 shows a side-rear perspective view of the module in Figure 1. Figure 3 shows a perspective view of the removable back cover of the module in Figures 1 and 2. Figure 4 shows an elevation view of the removable rear cover shown in Figure 3. Figure 5 shows a perspective view of one of the interchangeable decorative elements that complement the first module. Figure 6 shows a front elevation view of the second module. Figure 7 shows, finally, a profile view of the modular wall lamp with the first module and the second module coupled together. PREFERRED EMBODIMENT OF THE INVENTION In view of the figures described, it can be observed how the modular wall lamp of the invention shown in figure 7, is made up of two modules that have a complementary geometry, easily coupled and decoupled from each other manually by means of tongue and groove, which determine a single possible position of manual coupling between them, a first module (1), intended to be fixed to the wall, and a second module (2) with a character of coupled-decoupled from the first module (1) by means of a fixing system using complementary magnets More specifically, and as shown in Figures 1 and 2, the first module (1) acts as the wall mounting base and contains a core or chamber where the system's power, control, and communication modules are integrated. It is constructed from a main housing (3) that rests on the wall and is essentially disc-shaped. In the chosen practical embodiment, this housing has a diameter of approximately 185 mm, although these dimensions and shape could vary according to different design criteria without affecting the essence of the invention. The main housing (3) will include four anchor points (4) on the wall, strategically distributed, ensuring a firm, stable and perfectly aligned hold. The main housing (3) is divided into three levels. The first level (5) contains a cavity (6) that houses a high-power neodymium magnet. This magnet ensures the precise attachment of the second module (2) via a magnetic clamping system. This design allows the modules to align automatically and securely during assembly, simplifying subsequent handling and maintenance. For electrical current transmission, the system eliminates visible wiring and uses a direct contact mechanism. To achieve this, two aluminum pins (8) are located at the intermediate level (7), adjacent to the central neodymium magnet. These pins act as electrical conductors, allowing direct current transfer to the second module (2). This contact connection system ensures stable, safe, and durable electrical transmission, reducing the mechanical wear typical of traditional connection systems. The main housing (3) includes a space or chamber on its third level (9), the largest and closest to the wall, where the electronic components are integrated. Thus, the lower two-thirds of the internal volume are dedicated to housing these electronic components: the power, control, and communication modules necessary for the system's overall operation. To ensure optimal thermal performance and maintain the electronic components within their temperature parameters, a passive ventilation system has been implemented using channels (10) located on the side and rear of the first module (1), thereby facilitating the dissipation of heat generated during use. Finally, the entire electronic assembly is protected by a removable back cover (11) included in the first module (1), shown in Figures 3 and 4. This removable back cover (11) provides quick and convenient access to the internal components for maintenance, inspection or upgrade tasks, while ensuring a clean aesthetic finish once the decorative element (13) is installed. The removable back cover (11) has a transverse groove (12) designed to accommodate interchangeable decorations, such as the decorative element (13) shown in Figure 5, which includes an arm (14) that can be inserted into the transverse groove (12). This decorative element (13) can be made of materials such as brass, aluminum, wood, or resins, allowing the lamp's appearance to be adapted to the user's environment. Optionally, a separator element could be placed between the two modules, attachable by means of complementary magnetic elements, which increases the distance between the second module (2) and the wall when the user requires it, allowing the depth or aesthetic inclination of the lamp to be adjusted. This intermediate separator element would be attached to the first module (1) and second module (2) using complementary magnets. Regarding the second module (2), and according to figures 6 and 7, it includes an optical cover (20), responsible for both the lighting and the aesthetic finish of the assembly and linked to a housing in which a metallic counterpiece is established that acts as a direct receiver of the magnet housed in the first module (1), As with the first module (1), in this second module (2) three formally and dimensionally complementary sectors of the levels present in the first module (1) are defined: Thus, in the second module (2) a first sector (15) is defined which includes the metal counterpiece that acts as a direct receiver of the magnet housed in the first module (1), ensuring its correct fixation by magnetic attraction. The complementary configuration between the first module (1) and the second module (2) ensures that they fit together precisely, guaranteeing automatic alignment and a firm hold using the magnetic system. Meanwhile, in the intermediate sector (16) of the second module (2), in the housing that is linked to the optical cover (20), two aluminum pins (8) are established, complementary to the pins (8) provided in the first module (1), and which in the coupling between the first module (1) and the second module (2) make electrical contact, directly transmitting the current to the integrated LED lighting system. The lighting system of the second module (2) consists of a strip of LEDs that runs around the perimeter of the lamp's interior, following its complete outline. This configuration generates a uniform, soft, and continuous light, without any shadows or interruptions in the light projection. The LEDs are powered directly from the system's central logic, making it ready for future versions with dimming capabilities or custom programming. In terms of mechanical fastening, the second module (2) features an additional anchoring system using four screws, which reinforces the stability and precision of the assembly. Two of these screws are strategically concealed beneath the electrical connection pins (8) and (8), preserving the exterior aesthetics of the modular wall lamp. The other two screws (17) remain visible and serve to fix the structure of the second module (2) to the optical cover (20). The optical cover (20) is made of a high-quality translucent material, carefully selected to optimize the uniform dispersion of the light generated by the LEDs. This cover acts as a diffuser, preventing glare and providing a clean, elegant, and homogeneous visual finish. The optical cover (20) itself is integrated directly onto an ornamental piece (18), which in one embodiment could be a piece of stone, such as natural onyx marble, and which provides the main decorative component of the wall sconce or lamp of the invention. The ornamental piece (18) used is available in different thicknesses ranging from 20 to 50 mm, allowing the final design to be adapted to the needs of each project or client. Furthermore, if a natural stone such as onyx marble is used for the ornamental piece (18), the chromatic variations derived from its natural origin give each unit a unique and unrepeatable character, reinforcing the aesthetic value and exclusivity of the whole. Based on this structuring, the second module (2) determines a movable piece that the user places or removes according to their choice based on the type of ornamental piece or design. The third sector (19) contains an NFC board, which allows electronic communication or automatic activation according to the final product configuration and powers the LEDs described above. The electrical and control system incorporated into the unit has been designed using an advanced logic approach, based on the use of state-of-the-art microcontrollers and radio frequency identification (RFID) technology. This system allows not only lighting control, but also the integration of identification functions, user customization, and advanced automation. The system's main power supply is provided via an IC320 C8 male-female connector, fully compatible with European household standards, allowing for safe connection to standard 230-240 V AC electrical networks. This AC input is initially processed by a power supply that converts the mains voltage into a stabilized 24 V DC, with a minimum supply capacity of 1 A. This 24 V DC voltage forms the operating basis for all the power electronic modules integrated into the system. From this primary power source, the system incorporates a step-down DC-DC converter module based on high-efficiency Buck technology. This module reduces the 24 V DC to a stable 5 V DC, the voltage required to power the low-power logic control circuits that manage the system. This voltage scaling allows for a high degree of energy efficiency and protects the control components from potential fluctuations in the main power line. The system's logic control core is based on a microcontroller, such as the commercially available ESP32 C3 SuperMini, which handles the central processing functions. Its main tasks include direct communication with the RFID reader, management of activation and control signals, and direct control of relays that operate lighting loads or any other connected actuators. Additionally, the ESP32 microcontroller integrates the possibility of wireless communication via WiFi or Bluetooth, which opens the door to future expansions of the system aimed at advanced home automation, remote control or integration with building automation platforms. The identification system consists of a PN532 RFID reader, configured to operate under the I2C protocol, enabling direct, fast, and efficient communication with the central microcontroller. This reader is compatible with NFC cards and tags, specifically the NTAG215 model with a 504-byte capacity, used as user authentication. Through this system, it is possible to identify authorized users, activate or deactivate the lighting system, and manage other devices according to the programmed logic, giving the modular wall lamp additional functionality beyond simple illumination. For activating electrical loads, the system includes a module with two 5V controlled relays. These relays control both the power supply for internal LED modules and external loads powered from the same 24V DC line or from additional auxiliary power sources. The microcontroller directly manages the control of these relays, allowing for the programming of multiple activation and deactivation scenarios based on the established operating logic. The NFC tags used, model NTAG215, allow the storage of identification data, programming of access permissions, customization of usage scenarios and advanced system management by authorized users. Thanks to this perfectly integrated electronic control system, the modular wall lamp not only offers reliable and efficient performance in terms of lighting, but also incorporates intelligent functionalities adaptable to various contexts of use, both in the residential, commercial or professional sphere.
