Marine rescue searchlight system with dual-axis azimuth control and gyro-stabilized beam projection

A marine rescue searchlight system with dual-axis azimuth control and gyro-stabilized beam projection, comprising:

• at least one life jacket having a detector and a lifesaving locator, wherein, when the detector detects that the at least one life jacket has fallen into water, the lifesaving locator measures a survival signal containing a survival coordinate and transmits the survival signal through a specific frequency;
• a searchlight installed on a boat and comprising:
• a base having an azimuth control structure and a gyroscope, the azimuth control structure being capable of performing 360-degree horizontal rotation and 270-degree elevation/depression angle adjustment, and the gyroscope is coupled to the azimuth control structure for compensating a tilt angle caused by waves and stabilizing the azimuth control structure;
• and
• an LED light source module coupled to and installed on the azimuth control structure, and provided with a built-in adjustable zoom structure for adjusting a central light intensity and an angle of incidence to emit a beam with a searchlight distance of 10 m˜2 km;
• and
• a control module installed on the boat and having a communication element and a positioning element, the communication element is coupled with the lifesaving locator and the LED light source module via signals, and the positioning element measures and records a boat position of the boat in real time, wherein
• when the control module receives the survival signal, the survival coordinate is used to calculate an azimuth and a distance of the at least one life jacket relative to the boat position, and drive the azimuth control structure to rotate in a horizontal angle and adjust an elevation/depression angle according to the azimuth and the distance such that:
• in a case that the distance is greater than a first benchmark value, the LED light source module is driven to enhance the central light intensity and adjust the angle of incidence to a narrow angle through the adjustable zoom structure to precisely project a beam to a location of the at least one life jacket, and
• in a case that the distance is smaller than a second benchmark value, the LED light source module is driven to reduce the central light intensity and adjust the angle of incidence to a wide angle through the adjustable zoom structure to precisely project the beam to the location of the at least one life jacket.
