As shown in Figure 1, when a ship's hull is shaken by waves, standard searchlights are also shaken. Since the irradiation position shifts, considerable effort is required to maintain lighting a set object. You can reduce the labor of persons operating a searchlight equipped with a stabilizer through the following, because you can maintain lighting in a set direction even when the ship's hull is shaken.
① Store the angle of lifting motion with the control panel.
② Detect the angle of the searchlight's inclination and calculate the difference with the stored angle.
③ Convert the calculated difference in angle to an electronic signal and operate the lifting motor. (If you have a biaxial stabilizer, you can maintain a constant angle for the rotational angle as well, by using a gyro signal.)
