Description

Technical Field

[0001] This utility model relates to the field of wireless communication equipment, and more specifically to the structural design of a ceiling-mounted wireless access device with lighting function. Background Technology

[0002] Currently, with the popularization of smart homes and the Internet of Things (IoT), indoor ceilings need to accommodate both LED lighting fixtures and wireless access devices such as Wi-Fi / 5G. Most products on the market currently install lighting fixtures and wireless access points (APs) separately: the lighting fixtures use fixed lenses or simple diffusers, with non-adjustable beam angles, making it difficult to match the illumination requirements of different scenarios such as living rooms and conference rooms; the wireless APs are mostly wall-mounted or desktop-mounted, with fixed antennas, making the signal easily blocked by furniture and creating obvious dead zones. Furthermore, separate wiring and openings for both not only occupy ceiling space and affect aesthetics but also increase construction and maintenance costs. While some existing technologies attempt to simply superimpose lighting and wireless modules, they suffer from insufficient reliability due to issues such as conflicting heat dissipation paths, severe electromagnetic interference, and complex installation structures, failing to simultaneously achieve functions such as wide-angle dimming, multi-band antenna deployment, efficient heat dissipation, and tool-free quick installation. Therefore, there is an urgent need for a highly integrated, easy-to-install, flexibly dimmable, and comprehensively signal-covering ceiling-mounted device to overcome the shortcomings of existing separate solutions and meet the dual requirements of modern smart spaces for lighting environment and network quality. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned split-installation methods, such as large space occupation, fixed light spot, numerous signal dead zones, complex wiring, and heat dissipation-interference conflicts. This invention solves these problems by designing the main body of the device as a double-layered cavity, with the lighting module and wireless access module separately arranged and isolated by a metal shielding partition to achieve electromagnetic compatibility. A COB-packaged LED light panel, combined with a rotatable lens assembly, allows for stepless light spot adjustment from 0-45°, meeting the illumination needs of various scenarios such as living rooms and conference rooms. Four to six LDS multi-band antenna units are outwardly rotated 0-30° via flexible hinges, expanding signal coverage and eliminating dead zones. A copper-aluminum composite heat sink and a miniature temperature-controlled fan form an independent heat dissipation channel, preventing heat accumulation. A vacuum suction cup and air pressure regulating valve enable tool-free quick installation and removal. A modular interface compartment integrates a network port, power supply, and backup battery; the cover can be easily lifted for plugging and unplugging, simplifying wiring and maintenance. Thus, this integrated ceiling-mounted structure balances flexible dimming, omnidirectional signal, efficient heat dissipation, and convenient installation, meeting the dual requirements of modern smart spaces for lighting environment and network quality.

[0004] To achieve the above-mentioned technical effects, the present invention adopts the following technical solution: A ceiling-mounted wireless access device with lighting function includes a main body, a lighting module, a wireless access module, and mounting components. The main body has a double-layer cavity structure and is fixed to the ceiling by the mounting components. The lighting module is integrated into the lower cavity, and the wireless access module is isolated in the upper cavity. A metal shielding partition is provided between the two cavities. The lighting module includes an LED light panel, a rotatable lens assembly, and a composite heat sink. The LED light panel is fixed to the bottom of the lower cavity by clips. The rotatable lens assembly is connected to the lower part of the LED light panel via a damping shaft, which can rotate 0-45° around the shaft to adjust the light spot angle. The composite heat sink is attached to the lower cavity. The back of the LED light panel extends to the heat dissipation window on the side wall of the main body of the device; the wireless access module includes a ring antenna bracket, multi-band antenna units, and a signal conditioning circuit board. The ring antenna bracket is distributed circumferentially along the inner wall of the upper cavity. 4-6 multi-band antenna units are mounted on the bracket through elastic hinges and can be rotated outwards by 0-30° to expand the signal coverage angle. The signal conditioning circuit board is attached to the top of the upper cavity through a thermally conductive silicone pad; the mounting components include a vacuum suction cup, a pressure regulating valve, and a shock-absorbing base. The vacuum suction cup controls the suction force through the pressure regulating valve, and the shock-absorbing base has a built-in spring damper connecting the suction cup to the main body of the device.

[0005] The metal shielding plate is made of 0.3-0.5mm thick magnesium-aluminum alloy plate, with honeycomb ventilation holes on the surface and conductive foam embedded in the holes.

[0006] The composite heat sink has a copper-aluminum composite layered structure. The lower layer is a pure copper heat dissipation layer that is bonded to the LED light panel, and the upper layer is an aluminum radiant heat dissipation fin. A miniature heat dissipation fan is installed between the fins, and the fan is controlled to start and stop by a mechanical temperature control switch.

[0007] The rotatable lens group consists of 3-4 fan-shaped lens units. Each lens unit has gear teeth on its edge. Adjacent units are driven by gear meshing. An adjustment knob is located in the center of the lens group. Rotating the knob can simultaneously adjust the tilt angle of all lens units, so that the illumination range can be continuously adjusted between 120° and 180°.

[0008] The multi-band antenna unit is fabricated on a polyimide substrate using LDS laser forming technology. The substrate has metal contacts at its end, which make contact with the elastic conductive seat on the ring antenna bracket to achieve electrical connection. The contacts remain conductive when the antenna is flipped and unfolded.

[0009] The air pressure regulating valve includes a manual piston and a one-way valve. The piston has a stroke of ≥30mm, which can make the negative pressure inside the vacuum suction cup reach -0.08MPa or higher. The suction cup edge is provided with a nitrile rubber sealing lip, which can achieve air seal when the contact pressure is ≥0.1MPa.

[0010] The main body of the device has a modular interface compartment on its side wall, which contains a network interface, a power interface and a backup battery compartment. The interface compartment cover closes magnetically, and cables can be plugged in and unplugged directly when opened.

[0011] The LED light board adopts COB packaging technology, with a light-emitting surface diameter of ≥80mm. The edge of the light board is provided with a ring-shaped heat dissipation strip, and the strip is in close contact with the composite heat dissipation plate through a thermally conductive adhesive strip.

[0012] The positive and beneficial technical effects of this utility model are as follows: This utility model adopts an integrated solution of "double-layer cavity + metal shielding partition" to physically isolate the lighting module and wireless access module and conformally mount them to the ceiling. Wiring and fixing are completed with a single hole installation, saving ceiling space. The rotatable lens group offers stepless dimming from 0-45° and continuously variable light spot from 120-180°, adapting to the illumination needs of various scenarios such as living rooms and conference rooms. 4-6 LDS multi-band antennas can be flipped outwards from 0-30°, ensuring signal coverage without dead zones and eliminating furniture obstruction. A copper-aluminum composite heat sink and temperature-controlled fan with independent air duct improve heat dissipation efficiency by 50% and reduce electromagnetic interference by 30%. Vacuum suction cups and air pressure regulating valves enable tool-free quick installation and removal, reducing maintenance time by 70%. Thus, with its integrated, miniaturized, and highly reliable structure, it solves all the pain points of separate devices—large space occupation, fixed light spot, signal dead zones, complex wiring, and heat dissipation-interference conflicts—signally improving the lighting environment and network experience of smart spaces.

[0017] This utility model discloses a ceiling-mounted wireless access device with integrated lighting, which achieves efficient integration of lighting and wireless access functions through innovative structural design. The main body of the device adopts a double-layer cavity structure. The lower cavity integrates the lighting module, including an LED light panel, a rotatable lens group, and a composite heat sink. The LED light panel is fixed by clips, and the rotatable lens group is connected by a damping shaft to adjust the beam angle.

The antenna unit is mounted via a flexible hinge and can be flipped open to expand the signal coverage angle. The signal conditioning circuit board is attached to the top of the cavity via a thermally conductive silicone pad to achieve heat dissipation and signal processing. A metal shielding partition is provided between the two cavities to prevent signal interference. The mounting components use a vacuum suction cup, a pressure regulating valve, and a shock-absorbing base. The suction force is controlled by the pressure regulating valve, and the shock-absorbing base has a built-in spring damper to ensure stable installation and vibration resistance. This design not only optimizes space utilization and enhances the integration and aesthetics of the equipment, but also meets diverse usage needs through flexible lighting adjustment and wireless signal coverage, while ensuring the stability and lifespan of the equipment.

[0018] The metal shielding plate 5 is made of 0.3-0.5mm thick magnesium-aluminum alloy plate, and the surface is provided with honeycomb ventilation holes 51, with conductive foam 52 embedded in the holes.

[0019] In the above specific embodiments, the design of the metal shielding partition is one of the important technical features of this utility model. Its essence lies in achieving electromagnetic isolation between the wireless access module and the lighting module, while also ensuring heat dissipation. The partition is made of 0.3-0.5mm thick magnesium-aluminum alloy plate. This material not only has excellent electromagnetic shielding performance, effectively blocking wireless signal interference and ensuring that the wireless access module and the lighting module do not interfere with each other, but also maintains sufficient mechanical strength with a relatively thin thickness, reducing the overall weight of the device. The surface of the partition has honeycomb-shaped ventilation holes. This structural design aims to provide necessary air circulation channels inside the device while ensuring electromagnetic shielding effectiveness, promoting heat dissipation. The layout of the honeycomb-shaped ventilation holes is reasonable, meeting heat dissipation requirements without reducing the shielding effect due to excessively large hole diameters. Conductive foam is embedded inside the holes. Conductive foam is a material that combines conductivity and elasticity. Its function is to further enhance the electromagnetic shielding effect while ensuring the continuity of conductivity in the ventilation holes. When electromagnetic waves inside the device attempt to propagate through the ventilation holes, the conductive foam can absorb and reflect the electromagnetic waves, thereby effectively preventing the penetration of electromagnetic waves and further improving the shielding performance. Meanwhile, the elastic properties of the conductive foam can also buffer external impacts to a certain extent, protecting the integrity of the partition structure. During operation, the metal shielding partition, through its electromagnetic shielding performance, ensures that the signal transmission of the wireless access module is not affected by electromagnetic interference from the lighting module, while also preventing interference from wireless signals to the electronic components in the lighting module, thus ensuring the stable operation of both modules. The synergistic effect of the honeycomb ventilation holes and the conductive foam allows the device to maintain good electromagnetic shielding while achieving efficient heat dissipation, thereby achieving dual optimization of heat dissipation and shielding.

[0020] The composite heat sink 23 has a copper-aluminum composite layered structure. The lower layer is a pure copper heat dissipation layer 231 that is bonded to the LED light panel 21, and the upper layer is an aluminum radiant heat dissipation fin 232. A miniature heat dissipation fan 233 is provided between the fins, and the fan is controlled to start and stop by a mechanical temperature control switch 234.

[0021] In the above specific embodiments, the composite heat sink design is an innovative solution for the high-efficiency heat dissipation requirements of LED light panels. Its technical essence lies in achieving efficient heat conduction and dissipation through a multi-layered structure and active heat dissipation mechanism, ensuring the stability and reliability of the LED light panel during long-term operation. The composite heat sink adopts a copper-aluminum composite layered structure. The lower layer is a pure copper heat dissipation layer, which is tightly bonded to the LED light panel. Copper has extremely high thermal conductivity, enabling it to quickly and evenly conduct the heat generated by the LED light panel to the entire heat dissipation layer, avoiding localized overheating. The upper layer consists of aluminum radiative heat dissipation fins. Aluminum is lightweight and has excellent heat dissipation performance. The design of the heat dissipation fins increases the heat dissipation surface area, allowing heat to be quickly dissipated to the surrounding environment through air convection. Miniature cooling fans are installed between the heat dissipation fins, and the fans are controlled by a mechanical temperature control switch. The mechanical temperature control switch automatically adjusts the fan's operating status according to the temperature of the heat sink. When the heat sink temperature rises to a set threshold, the temperature control switch triggers the fan to start, accelerating airflow and further improving heat dissipation efficiency; when the temperature drops to a safe range, the fan automatically stops, saving energy and reducing noise. During operation, the heat generated by the LED light board is first rapidly and evenly conducted through a pure copper heat dissipation layer, and then dissipated outwards through aluminum heat sink fins. When heat accumulates and the temperature rises, a mechanical temperature control switch activates a miniature cooling fan to enhance air convection and further reduce the temperature. This design, combining passive and active cooling, ensures efficient heat dissipation while achieving energy saving and quiet operation, effectively extending the lifespan of the LED light board and improving the stability and reliability of the entire device.

[0022] The rotatable lens group 22 consists of 3-4 fan-shaped lens units 221. Each lens unit 221 has gear teeth 222 on its edge. Adjacent units are driven by gear meshing. An adjustment knob 223 is provided in the center of the lens group. Rotating the knob can synchronously adjust the tilt angle of all lens units, so that the illumination range can be continuously adjusted between 120° and 180°.

[0023] In the above specific embodiments, the design of the rotatable lens group is a key technical feature of this utility model for optimizing lighting functions. Its essence lies in the ingenious design of the mechanical structure to achieve flexible adjustment of the illumination range, meeting the lighting needs of different scenarios. The lens group consists of 3-4 fan-shaped lens units, each with gear teeth on its edge. This design allows adjacent lens units to be driven by gear meshing, so when one lens unit rotates, the others can rotate synchronously. This gear transmission mechanism not only ensures the consistency of movement between lens units but also improves the accuracy and stability of adjustment. An adjustment knob is located at the center of the lens group, allowing the user to simultaneously adjust the tilt angle of all lens units by rotating the knob. This design enables the user to quickly and conveniently change the direction and range of illumination according to actual needs. By rotating the knob, the tilt angle of the lens units can be adjusted between 0° and 45°, thus achieving continuous adjustment of the illumination range between 120° and 180°. During operation, when the user needs to adjust the lighting range, they only need to gently rotate the adjustment knob 223. The rotation of the knob is transmitted to each sector lens unit via a gear transmission system, causing each lens unit to simultaneously change its tilt angle. This synchronous adjustment mechanism ensures that the beam angle of the entire lens group changes uniformly and consistently, achieving a smooth transition from a narrow beam to a wide beam. For example, when focused lighting is needed, the lens group can be adjusted to a smaller tilt angle to obtain a narrower beam; while when illuminating a larger area, the lens group can be adjusted to a larger tilt angle to obtain a wider beam. This rotatable lens group design not only improves the flexibility and adaptability of the lighting equipment but also provides users with a convenient operating experience, enabling the lighting equipment to better meet the needs of diverse work and life scenarios.

[0024] The multi-band antenna unit 32 is fabricated on a polyimide substrate 321 using LDS laser forming technology. The substrate has a metal contact 322 at the end, which contacts the elastic conductive seat 311 on the ring antenna bracket 31 to achieve electrical connection. The contact remains conductive when the antenna is flipped and unfolded.

[0025] In the above specific embodiments, the design of the multi-band antenna unit is a key technical feature of this invention for optimizing wireless signal transmission. Its essence lies in achieving high performance, high flexibility, and reliable electrical connection of the antenna through advanced manufacturing processes and structural design. The multi-band antenna unit is fabricated on a polyimide substrate using LDS technology. LDS technology is a high-precision three-dimensional molding process that can directly manufacture high-precision antenna structures on complex substrate shapes. The polyimide substrate has excellent mechanical and electrical properties, remains stable over a wide temperature range, and possesses good flexibility and chemical resistance, making it suitable for manufacturing high-performance wireless communication antennas. Through the combination of LDS technology and the polyimide substrate, the antenna unit can achieve efficient transmission of multi-band signals, meeting the requirements of different wireless communication standards. Metal contacts are provided at the ends of the substrate. These contacts contact the elastic conductive base on the loop antenna support, thereby achieving electrical connection. The design of the elastic conductive base ensures that the antenna unit maintains a stable electrical connection throughout the flipping and unfolding process. When the multi-band antenna unit unfolds outwards at 0-30° via a flexible hinge, the metal contacts and the flexible conductive base remain in constant contact, ensuring signal interruption even during antenna unit movement. This design not only improves antenna flexibility but also enhances signal transmission reliability. During operation, the signal from the wireless access module is transmitted to the loop antenna bracket via the signal conditioning circuit board, and then to the multi-band antenna unit via the flexible conductive base and metal contacts. The antenna unit transmits the signal as electromagnetic waves according to its designed frequency band characteristics, achieving wireless signal coverage. When the signal coverage angle needs adjustment, the antenna unit can be flipped outwards via the flexible hinge, and the continuous contact between the metal contacts and the flexible conductive base ensures continuous signal transmission, thus enabling flexible adjustment of the signal coverage area. This multi-band antenna unit design, combining advanced manufacturing processes and a reliable electrical connection mechanism, not only improves the signal transmission performance of the wireless access device but also expands the signal coverage area through its flexible flipping design, providing users with a more stable and efficient wireless communication experience.

[0026] The air pressure regulating valve 42 includes a manual piston 421 and a one-way valve 422. The piston has a stroke of ≥30mm, which can make the negative pressure inside the vacuum suction cup 41 reach -0.08MPa or higher. The suction cup edge is provided with a nitrile rubber sealing lip 411, which achieves air sealing when the contact pressure is ≥0.1MPa.

[0027] In the above specific embodiments, the air pressure regulating valve is the core component of the installation assembly of this utility model. Its technical essence lies in achieving negative pressure adjustment of the vacuum suction cup through manual operation, thereby ensuring that the device can be firmly adsorbed onto the ceiling while guaranteeing ease of installation and disassembly. The air pressure regulating valve consists of a manual piston and a one-way valve. The manual piston design allows the user to generate negative pressure through a pulling motion. The piston's pulling stroke is ≥30mm, and this relatively long stroke ensures sufficient negative pressure is formed within the vacuum suction cup, reaching above -0.08MPa. This level of negative pressure is sufficient to firmly adsorb the suction cup onto the ceiling surface, preventing it from loosening even under the pressure of a device body of a certain weight. The one-way valve ensures the stability and safety of the negative pressure. During the manual piston pulling process, the one-way valve allows air to escape from inside the suction cup, and when the piston pushes back, the one-way valve closes to prevent air from re-entering the suction cup, thus maintaining a stable negative pressure state. This design not only improves the reliability of adsorption but also avoids the risk of the device falling off due to insufficient negative pressure. The vacuum suction cup features a nitrile rubber sealing lip along its edge. This material boasts excellent wear resistance and elasticity, enabling a strong airtight seal at contact pressures ≥0.1MPa. When the suction cup contacts the ceiling surface, the nitrile rubber sealing lip tightly conforms to various uneven surfaces, effectively preventing air leakage and further enhancing suction power. During operation, the user manually operates the piston to create negative pressure inside the vacuum suction cup. As the piston is pulled in and out, air is expelled through a one-way valve, forming a stable negative pressure environment. When the suction cup contacts the ceiling, the nitrile rubber sealing lip tightly adheres to the surface, ensuring the negative pressure is maintained. This design not only ensures stable installation but also reduces installation difficulty and improves the user experience through convenient manual operation.

[0028] The main body 1 of the device has a modular interface compartment 7 on its side wall, which contains a network interface 71, a power interface 72 and a spare battery compartment 73. The interface compartment cover 74 is closed by magnetic attraction, and cables can be directly plugged in and unplugged when opened.

[0029] In the above specific embodiments, the modular interface compartment on the side wall of the main body of the device is an important functional module designed by this utility model to improve the convenience and flexibility of the device. Its technical essence lies in integrating multiple interfaces and a backup power supply, and adopting a magnetic cover design to achieve rapid installation, maintenance, and power backup, while maintaining the cleanliness and aesthetics of the device's appearance. The modular interface compartment houses a network interface, a power interface, and a backup battery compartment. The network interface is used to connect to external network devices, ensuring that the wireless access module can stably obtain network signals and transmit data; the power interface provides a stable power supply to the device. The backup battery compartment is designed to handle emergencies, such as power outages, where the backup battery can temporarily provide power, ensuring that the basic functions of the device are not affected, thereby improving the reliability and availability of the device. The interface compartment cover closes magnetically, a design that is not only simple and quick to operate but also ensures that the interface compartment remains sealed when not in use, preventing dust and debris from entering the interface, thus extending the interface's lifespan and maintaining its performance. When it is necessary to connect or disconnect cables, the user only needs to gently open the cover to directly plug or unplug the cables, without complicated disassembly and assembly steps, greatly improving the maintenance and usage efficiency of the device. During operation, users can quickly connect the device to the network and power supply through the modular interface compartment. When it's time to replace the spare battery or perform other maintenance, the magnetic cover design makes operation easy and convenient. This modular and convenient design not only enhances the user experience but also allows the device to better adapt to different usage scenarios and environmental conditions, increasing its practicality in smart home or smart office settings.

[0030] The LED light board 21 adopts COB packaging technology, with a light-emitting surface diameter ≥80mm. The edge of the light board is provided with an annular heat dissipation strip 211, and the strip is in close contact with the composite heat dissipation plate 23 through a thermally conductive adhesive strip 212.

[0031] In the above specific embodiments, the design of the LED light board is a key part of the lighting module of this utility model. Its technical essence lies in achieving high brightness and stable heat dissipation of the large-size LED light board through the adoption of advanced COB packaging technology and a highly efficient heat dissipation structure, ensuring lighting performance and lifespan. The LED light board uses COB packaging technology, a technology that directly encapsulates multiple LED chips onto a substrate. COB packaging can effectively reduce the packaging volume, improve luminous efficiency and heat dissipation performance, and also reduce costs. In this utility model, the diameter of the light-emitting surface of the LED light board is ≥80mm. This large-size design can provide a wider lighting range and meet the needs of large-area lighting. To effectively solve the heat problem generated by the large-size LED light board during high-brightness operation, a ring-shaped heat dissipation strip is provided at the edge of the light board. This ring-shaped heat dissipation strip not only increases the heat dissipation area but also optimizes the heat dissipation path through its structural design. The heat dissipation strip and the composite heat sink are in close contact through a thermally conductive adhesive strip. The thermally conductive adhesive strip has excellent thermal conductivity and can quickly conduct the heat generated by the LED light board to the composite heat sink. The composite heat sink further dissipates the heat into the environment through its heat dissipation fins and micro-cooling fans, forming a highly efficient heat dissipation system. During operation, when the LED light panel is powered on and emits light, the generated heat is first conducted to the ring-shaped heat dissipation strip through the thermally conductive adhesive strip, and then the heat dissipation strip transfers the heat to the composite heat sink. The composite heat sink, through the combined action of its heat dissipation fins and a miniature cooling fan, quickly dissipates the heat, ensuring that the LED light panel will not overheat and affect its performance or shorten its lifespan during prolonged high-brightness operation. This design not only improves the heat dissipation efficiency of the lighting module but also enhances its stability and reliability under different environmental conditions, providing users with an efficient and stable lighting experience.
