[0021] The lighting fixture proposed in this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the explanation of the embodiments of the present invention. Furthermore, the structures shown in the drawings are often part of the actual structure. In particular, different figures may emphasize different aspects and sometimes use different proportions.

[0022] like Figure 1 As shown, this utility model provides a lighting fixture, which is mainly used for lighting in homes, offices, or squares. The LED light source switch function can be obtained by scanning the top light diffuser of the lighting fixture with the NFC function of a mobile phone, thereby adjusting the LED light intensity.

[0023] A lighting fixture with NFC functionality includes a lamp body assembly, a circuit board, and an NFC antenna. The NFC antenna includes an NFC antenna mount 5 and an NFC antenna assembly 6. The NFC antenna assembly 6 is attached to the upper surface of the NFC antenna mount 5 using double-sided adhesive. The NFC antenna mount 5 is fixed to the electronic component layer of the PCBA circuit board assembly 4 using hot melt adhesive. The NFC antenna assembly 6 includes an NFC coil 610, and a first feed line 640 and a second feed line 650 on the NFC coil 610 are soldered to the surface pads of the PCBA circuit board assembly 4. The overall module composed of the NFC antenna mount 5, the NFC antenna assembly 6, and the PCBA circuit board 4 is then fixedly assembled into the housing 2 using the PCBA circuit board assembly 4.

[0024] In this embodiment, the lighting fixture is installed on the control panel. The control panel is a wall-mounted panel or an integrated device panel. The control panel has mounting holes that match the external threads of the housing 2, and the lighting fixture is screwed in and fixed through the external threads of the housing. The power cord on the reverse side of the PCBA circuit board assembly 4 is connected to a common power source to form a current path, which can control the LED light to turn on and off under the action of a switch. With this configuration, the NFC antenna assembly 6 is matched and connected to the NFC function of the mobile terminal when the operator uses it. The operator can scan the light diffuser 1 on the top of the lighting fixture using the NFC function of the mobile phone to obtain the LED light source switch function, and can adjust the LED light intensity. The main purpose of adjusting the light source intensity through the NFC function is to achieve energy saving and environmental protection.

[0025] The lamp body assembly includes a light diffuser 1, a housing 2, and a waterproof sealing ring 3. The light diffuser 1 is made of transparent polycarbonate material with a frosted inner surface. It is embedded in the upper surface of the housing 2 using an in-mold injection molding process, achieving light transmission. The secondary injection molding process ensures a zero-gap fit, thus achieving waterproofing. The housing 2 is made of plastic alloy composite material. The outer surface of the housing 2 has striped anti-slip textures to enhance its anti-slip function, and the outer surface of the housing 2 has an external thread structure for easy installation and fixation. The waterproof sealing ring 3 is located at the bottom of the housing 2 and mates with the mounting panel of the lighting fixture. This increases the product's sealing performance, improves its waterproof rating, and extends its service life.

[0026] PCBA circuit board assembly 4 includes control circuitry, a micro-switch controller, an LED array, a power module, and resistive components. These components are soldered to the surface of PCBA circuit board assembly 4 using SMT (Surface Mount Technology). PCBA circuit board assembly 4 is then secured to the inner cavity of housing 2 with anti-loosening screws to prevent water droplets from entering the circuitry and affecting product functionality, thus improving safety and reliability.

[0027] Specifically, the NFC antenna assembly 6 includes an NFC coil 610, a ferrite core 620, and double-sided adhesive tape 630. The NFC coil 610 is configured as a single-strand copper coil with a wire diameter ranging from 0.19mm ± 0.01mm, using a single-sided 4 (6 layers) double-layer alpha winding. The wire diameter, number of turns, and number of layers of the NFC coil 610 can be adjusted according to the actual electrical performance parameters of the product. The ferrite core 620 can use a core thickness of 80μm, 100μm, or 120μm, with a permeability P = 130~180@100KHz. This refers to the permeability of the ferrite fluctuating between 130 and 180 H / m under an alternating magnetic field at a frequency of 100KHz; the testing standard allows for permeability fluctuation within a certain range. Specific specifications can be selected based on the actual electrical performance parameters of the product. Double-sided tape 630 is available in thicknesses of 0.05mm, 0.10mm, or 0.15mm, and models can be selected from 3M series, Tesa series, or other brands.

[0028] Furthermore, the NFC coil 610 is attached to the upper surface of the double-sided adhesive 630, and its components are then attached to the upper surface of the ferrite 620. The resulting NFC antenna assembly 6 is then attached to the NFC antenna mounting base 5 via the double-sided adhesive 630 on the back of the ferrite 620. The NFC antenna mounting base 5 is made of transparent polycarbonate material. The NFC antenna is then fixed to the upper surface of the PCBA circuit board assembly 4 using UV adhesive to prevent it from detaching due to the heat generated by the LED beads on the PCBA circuit board assembly 4.

[0029] In this embodiment of the invention, the PCBA circuit board assembly 4 provides power to its surface LED bead array, enabling it to emit light. Multiple LED beads on the surface of the PCBA circuit board assembly 4 emit light through the diffuser 1. During use, the operator can, according to the environment and desired light intensity, use their mobile phone's NFC function to approach the surface of the diffuser 1, identify the NFC antenna assembly 6, and thus achieve data matching and connection. This allows the operator to obtain control over the circuit switches on the PCBA circuit board assembly 4 and adjust the light source size as needed. In actual use, the operator can scan the QR code in the product manual with their mobile phone to download and install the accompanying mobile application. When it is necessary to turn the LED light on or off, or adjust the LED light, the operator can approach the mobile phone with their mobile phone to select control commands through the mobile phone software interface. The mobile phone's NFC chip generates a radio frequency signal according to the operation command, which is received by the NFC antenna assembly 6 inside the lamp, and the signal is transmitted through I... 2The C-bus transmits data to the main control chip, which parses the instructions and outputs a PWM (Pulse Width Modulation) dimming signal to adjust the LED lights. Real-time status data can be fed back to a mobile phone via load modulation. This lighting fixture not only allows for short-range wireless communication control via mobile terminals such as smartphones, eliminating the need for wiring and making installation and maintenance more convenient, but also features a waterproof and sealed design, improving the product's waterproof rating and lifespan, and enhancing its safety and reliability.

[0030] In summary, this utility model provides a lighting fixture with NFC functionality. The lighting fixture includes a lamp body assembly, a circuit board, and an NFC antenna. The lamp body assembly includes a diffuser 1, a housing 2, and a waterproof sealing ring 3. The circuit board is fixedly installed within the inner cavity of the housing 2. The NFC antenna includes an NFC antenna mount 5 and an NFC antenna assembly 6, with the NFC antenna assembly 6 located above the NFC antenna mount 5. The NFC antenna is fixed above the electronic component layer of the circuit board.
