NAVIGATION LIGHTS CONTROL DEVICE Russian patent published in 2023 - IPC G08G3/00 G01R31/08 

FIELD: navigation equipment.

SUBSTANCE: device for monitoring the operation of navigation lights. The device contains a photodetector, a generator and a power source. The power supply inputs are connected to the supply conductors of the electric lamp. The lamp is installed in the navigation light. The power supply output is connected to the generator. The generator input is connected to the photodetector output. The output of the generator is connected to one of the supply conductors of the electric lamp. The supply conductors of the electric lamp installed in the navigation light are connected to the corresponding switch. Each decoder cell is connected to the common wire of the switch and contains a capacitor, with which the primary winding of the transformer is connected in series. The secondary winding of the transformer is connected to the corresponding inputs of a bridge rectifying circuit, the corresponding output of which is connected to the gate of the field-controlled transistor. The source of the transistor is connected to the first terminal of the constant voltage source. The drain of the field-controlled transistor is connected to the first terminal of the potentiometer and the first terminal of the relay coil. The second terminal of the potentiometer is connected to the input of the LED, the output of which is connected to the second terminal of the constant voltage source, to which the second terminal of relay coil is also connected. The relay's opening contact is connected in series with the closing contact of the corresponding switch.

EFFECT: automatic control of the operation of the vessel's navigation lights is achieved.
