[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, an explosion-proof lamp with wireless control and sensing functions includes a radiator housing 4, a radiator connecting ring 3, and a wiring cavity housing 2. A sealing joint 8 is connected to the outer wall of the wiring cavity housing 2, and an antenna 9 is connected to the sealing joint 8. A driving power supply 14 is provided inside the radiator housing 4. The driving power supply 14 is of model ELG-75. A single lamp controller 12 is provided inside the radiator connecting ring 3. The single lamp controller 12 has a built-in wireless communication chip of model CC2530. A PC cover 5 is provided at the bottom of the radiator housing 4. The radiator housing 4 and the PC cover 5 are connected by a second adhesive bonding surface 405. The detection end of the microwave detection sensor 16 extends through the onboard light source board 15 into the PC cover 5 for detecting the movement of personnel or vehicles.

[0023] The single-lamp controller 12 has an internal control unit, which performs functions such as signal processing, logic judgment, and control command issuance. This control unit can be a single-chip microcomputer, model STM32F030. An onboard light source board 15, model 3030-SMD, is mounted on the bottom of the heat sink housing 4. A microwave detection sensor 16, model RCWL-0516, is located inside the center of the heat sink housing 4. The single-lamp controller 12 is electrically connected to the dimming input terminal of the drive power supply 14, and the output terminal of the drive power supply 14 is electrically connected to the onboard light source board 15. The microwave detection sensor 16 is signal-connected to the single-lamp controller 12. The single-lamp controller 12 receives remote control signals through the antenna 9 and receives signals from the microwave detection sensor 16 to adjust the output parameters of the drive power supply 14 to control the brightness of the onboard light source board 15.

[0024] In use, the single lamp controller 12 receives control signals from a remote control system (such as a smart lighting platform or a factory central control system) via the antenna 9. Based on the received remote control signals, the single lamp controller 12 adjusts the output voltage and current parameters of the drive power supply 14, thereby adjusting the brightness of the onboard light source board 15 and realizing remote intelligent dimming control.

[0025] Meanwhile, the microwave detection sensor 16, located inside the center of the radiator housing 4, can monitor the movement of people or vehicles within the lighting area in real time. When a person or vehicle is detected entering the sensing range, the microwave detection sensor 16 transmits the sensing information to the single-lamp controller 12 in real time via a signal line. The single-lamp controller 12 responds immediately, adjusting the output voltage and current parameters of the drive power supply 14 to automatically increase the brightness of the onboard light source board 15 to meet the instantaneous enhanced lighting requirements.

[0026] The single-lamp controller 12 supports a dual-channel intelligent control mode, which can respond to remote control signals and microwave detection sensor 16 signals respectively according to preset priority logic, prioritizing the immediate response to personnel or vehicle detection triggers. When no one or a vehicle leaves the sensing area, the single-lamp controller 12 reduces the output power of the drive power supply 14 according to preset parameters, restoring the lamp to energy-saving mode, ensuring efficient and safe lighting management.

[0027] like Figures 1-4 As shown, the heat sink housing 4 has a heat dissipation cavity inside. A light source cavity is formed between the bottom of the heat sink housing 4 and the PC cover 5. The light source cavity is connected to the heat dissipation cavity through a wire hole. A wire hole is provided with a wire sealing 404 to prevent pressure superposition.

[0028] During use, a wire-passing seal 404 is installed in the wire-passing hole at the connection between the light source cavity and the heat dissipation cavity to ensure the sealing of the wire connection and prevent pressure buildup. The separation design of the light source cavity and the heat dissipation cavity ensures that the pressure difference between them will not pose a safety hazard to the lighting device.

[0029] like Figures 1-4 As shown, the radiator housing 4 is connected to the radiator connecting ring 3 via the first adhesive bonding surface 403. The radiator connecting ring 3 is connected to the wiring cavity housing 2 via the explosion-proof thread 302. The wiring cavity housing 2 is provided with a wiring cavity cover 1. A stop joint surface 102 is provided between the wiring cavity housing 2 and the wiring cavity cover 1. A first O-ring 11 is provided between the wiring cavity housing 2 and the wiring cavity cover 1. A second O-ring 13 is provided between the radiator connecting ring 3 and the wiring cavity housing 2.

[0030] In use, a radiator connecting ring 3 is provided between the radiator housing 4 and the wiring cavity housing 2, and is connected to the wiring cavity housing 2 via an explosion-proof thread 302. Furthermore, the wiring cavity housing 2 and the wiring cavity cover 1 are connected via a stop-fit ​​surface 102, with a first O-ring 11 ensuring a tight seal, while a second O-ring 13 is located between the radiator connecting ring 3 and the wiring cavity housing 2, further enhancing the seal. These precise connection designs effectively prevent gas leakage inside the equipment, ensuring the explosion-proof performance of the device.

[0031] like Figures 1-4 As shown, the PC cover 5 is provided with several fastening screws 6, which are connected to the radiator housing 4. The wiring cavity cover 1 is provided with several anti-drop bolts 10, the threaded end of the anti-drop bolts 10 is connected to the wiring cavity housing 2. The outer wall of the wiring cavity housing 2 is provided with set screws 7, the end of the set screws 7 abuts against the top of the radiator connecting ring 3 to prevent the explosion-proof thread 302 from loosening.

[0032] In this device, the PC cover 5 is connected to the radiator housing 4 by fastening screws 6, ensuring the robustness of the connection and effective heat dissipation. The wiring cavity cover 1 is connected to the wiring cavity housing 2 by anti-drop bolts 10, and set screws 7 are installed on its outer wall to prevent the explosion-proof threads 302 from loosening due to external force or vibration. These precise connection structures ensure the stability of the device under high pressure, high temperature, and vibration operating environments, enhancing its explosion-proof performance and safety.
