Background
The searchlight is a device, which has a strong light source and a concave mirror capable of intensively projecting light to a specific direction, is used for remote illumination and search, can concentrate an emergent light beam in a small solid angle by virtue of a reflector or a lens to obtain larger light intensity, and is mostly rich in foot stands or movable carriers, and large searchlights even have special trucks as carriers in consideration of the volume, weight and convenient operation of the device. At the present stage, an airport runway can be provided with a large number of searchlights to guide an airplane to land, if a power failure accident happens suddenly, airport personnel are required to drive a vehicle carrying a large-scale searchlight to arrive at the airport runway, and the airplane above the airport runway is guided to land, but the traditional searchlights generally have limitations, the searchlights are limited in irradiation angle, omnidirectional irradiation cannot be realized, the positions of the vehicles need to be continuously adjusted while the irradiation angle is adjusted, in addition, workers manually adjust the irradiation angle of the searchlights, a large amount of physical strength and mental concentration force needs to be consumed, and misoperation is easy to occur.
Chinese patent document No. 201610926182.4 discloses a marine searchlight, which is characterized in that: the LED lamp comprises a lamp barrel, wherein a reflecting bowl, a motor and a movable support are arranged in the lamp barrel, the movable support comprises a ball screw and an L-shaped connecting piece, one end of the L-shaped connecting piece is fixed at the bottom of the reflecting bowl, the other end of the L-shaped connecting piece is in threaded connection with the ball screw, the motor is arranged at the bottom of the lamp barrel, and the ball screw is coaxially connected with an output shaft of the motor; the lamp tube is internally provided with a fixed support and a bulb, the bulb is fixed on a central shaft of the lamp tube through the fixed support, the fixed support comprises a connecting rod and annular connecting pieces which are respectively sleeved at two ends of the bulb, and two ends of the connecting rod are respectively in threaded connection with the annular connecting pieces and the wall of the lamp tube; the top end of the lamp tube is open, and a light-transmitting sheet seals the top end opening of the lamp tube. It has the problems that: the searchlight only supports the pitching motion in the vertical direction, but cannot realize the steering motion in the horizontal direction, so that the irradiation angle is limited, and in addition, when the searchlight is actually used, a worker needs to manually control the pitching motion of the lamp tube, so that the labor intensity is high.
