The light emitting efficiency and the light emitting effect of the spotlight 100 are improved by arranging two different stages of lens joint modulation. In addition, the first focusing structure 6 and the second focusing structure 7 are connected in a rotating mode to adjust the distance between the two stages of lenses to achieve large-range zooming, and the zoom lens is convenient to operate and simple in structure. Through adopting three-way screw thread on first focusing structure 6 and second focusing structure 7, turned angle is little during the focusing, can fix a position fast, and after the required position of adjustment, can pass through the automatic locking of frictional force, need not to increase extra locking device, reduces shot-light 100's cost.

Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
