Without disassembling the lamp, users can wirelessly control the lead screw linear module via a controller to adjust the lamp's position. During the day, when the lamp is not needed, it can be moved into the charging box for safekeeping and protection. When needed, the lamp can be moved out.

[0028] This invention discloses a multifunctional marine lamp, with reference to... Figure 1 and Figure 5 The device includes a lamp mobile housing 1, a charging box 5 at the rear end of the lamp mobile housing 1, lamps 2 symmetrically arranged on both sides of the front and lower surfaces of the lamp mobile housing 1, a controller 3 between the two lamps 2, the output end of the controller 3 being electrically connected to the control end of the lamp 2, the controller 3 including a wireless transmission module, and the controller 3 being wirelessly connected to the user terminal through the wireless transmission module.

[0030] The communication module includes a signal transceiver module and a coupling circuit. The signal transceiver module is connected to the controller 3 through the coupling circuit.

[0031] In a further implementation, refer to Figure 6The power conversion circuit includes a first voltage input terminal, a first diode D1, a first capacitor C1, a second capacitor C2, a first power chip, a second diode D2, a first inductor L1, a third capacitor C3, a first voltage output terminal, a second voltage input terminal, a fourth capacitor C4, a second power chip, a first resistor R1, a second resistor R2, a fifth capacitor C5, and a second voltage output terminal.

[0032] The first voltage input terminal is connected to the cathode of the first diode D1, one end of the first capacitor C1, one end of the second capacitor C2, and the first chip voltage input terminal VIN of the first power supply chip. The other end of the first diode D1 is connected to the other end of the first capacitor C1, the other end of the second capacitor C2, the first chip on / off control terminal ENA of the first power supply chip, the first chip ground terminal GNDA of the first power supply chip, the anode of the second diode D2, and one end of the third capacitor C3 and grounded.

The analog signal input terminal is connected to one end of the third resistor R3 and one end of the fourth resistor R4.

The other end of the sixth capacitor C6 is connected to the other end of the third resistor R3 and the positive input terminal of the operational amplifier U1. The negative input terminal of the operational amplifier U1 is connected to the output terminal of the operational amplifier U1.

[0035] Specifically, this invention selects the AD8608 operational amplifier chip from Analog Devices (ADI). This chip combines many excellent features, providing four-rail input and output while operating on a single power supply. It ensures high speed while maintaining extremely low noise and input bias current, making it widely applicable to various circuits. Since the input impedance of operational amplifiers is generally very high, they are easily affected by external interference when the input pin is floating. Therefore, setting a fourth resistor R2 can ensure that the input terminal forms a loop with the analog ground when the input pin is floating, thus ensuring the stability of the operational amplifier.

[0036] In a further implementation, refer to Figure 2 and Figure 3 The outer walls on both sides of the lamp moving housing 1 are provided with two upper and lower assembly slots 6. The assembly slots 6 are respectively provided with a lead screw linear module 7 and a driven moving part 15. One end of the lead screw linear module 7 and the driven moving part 15 extends into the charging box 5. The lead screw linear module 7 includes a ball screw 13. The end of the ball screw 13 is provided with a lead screw motor. The outer wall of the ball screw 13 is provided with a lead screw slider 14. The lead screw slider 14 is assembled and installed with the assembly slot 6 by screws. The driven moving part 15 is provided with a guide rod 16 inside. The outer wall of the guide rod 16 is fitted with a driven slider 17. When the lamp moving housing 1 moves, it drives the driven slider 17 to move on the guide rod 16, making the movement of the lamp moving housing 1 more stable. Moreover, the combination of rod and slider makes it less likely to be dislodged by vibration and other factors.

[0037] Specifically, the linear screw module 7 drives the lamp moving housing 1 to move, adjusting the lighting range of the lamp 2. Without disassembly, users can wirelessly control the linear screw module 7 via the controller 3, causing the screw motor and ball screw 13 to move the screw slider 14, which in turn moves the lamp moving housing 1, thus adjusting the lighting position of the lamp 2. Compared to traditional manual disassembly and replacement, in situations where the lamp 2 is not needed during the day, it can be moved to the charging box 5 for storage, protecting the lamp 2. When needed, the lamp 2 can be moved out. The two sets of lamps 2, one in the front and one in the bottom, expand the illumination angle and range, allowing users to easily turn on the lamps 2 at the desired location.

[0038] In a further implementation, refer to Figure 2 and Figure 4 The lamp mobile housing 1 has a built-in battery 19 inside, and the charging box 5 has a magnetic charging assembly 8 inside. The magnetic charging assembly 8 includes a magnetic charger 9 located in the middle of its front face. The rear face of the lamp mobile housing 1 has a magnetic charging port 10, and the built-in battery 19 is magnetically charged with the magnetic charger 9 through the magnetic charging port 10. The magnetic charger 9 has an embedded groove 11 on one side, and a pressure sensing plate 12 is installed inside the embedded groove 11. The end of the pressure sensing plate 12 protrudes out of the embedded groove 11. The output end of the pressure sensing plate 12 is wirelessly connected to the input end of the controller 3. The upper surface of the lamp mobile housing 1 has multiple heat sinks 4, which can dissipate heat from the lamp body and battery and other components inside the lamp mobile housing 1.

[0039] Specifically, the built-in battery 19 is used to enable the lamp 2 to continue lighting even when the power is off, thereby improving safety. The battery power module 18 monitors the power of the built-in battery 19 in real time. When the power drops to a set range, the battery power module 18 sends a signal to the controller 3. The controller 3 controls the lead screw linear module 7 to move the lamp moving box 1 into the charging box 5. When the lamp moving box 1 moves to the magnetic charging component 8, it touches the pressure sensor 12, which sends a signal to the controller 3, causing the controller 3 to stop moving backward and magnetically attract the magnetic charging port 10 and the magnetic charger 9 for magnetic charging.
