Abstract

The invention discloses a spotlight. The spotlight comprises a fixing box; the fixing box is internally provided with a transmission cavity, a worm is rotationally installed between the left inner wall and the right inner wall of the transmission cavity, and the end surface of the left side of the worm is fixedly provided with a rotary knob; the upper portion of the transmission cavity is providedwith a rotary cavity in a communicating mode; when shading plates need to be used for shading, a motor is started to drive a threaded rod to rotate, the threaded rod rotates to drive a threaded blockto move rightwards, the threaded block moves rightwards to drive a fixing rod to move rightwards, thus, the fixing rod pushes the shading plates to get close to each other for shading through a connection rod and a push rod, rotating of the shading plates can be adjusted through the motor, and the shading function is achieved through the shading plates without manual adjustment; and in addition,the light ray emitting angle of the spotlight can be adjusted by turning the rotary knob quite conveniently.
