Abstract:
The present invention discloses variable focus spotlight with spin type focusing structure, the variable focus spotlight includes a shell, a driving ring and a focusing module. With the implementation of the present invention, the focusing module slides toward or away from the light source in the shell by rotating a driving ring which pulls the connecting rods penetrating position spiral slits on the shell, so that the variable focus spotlight with spin type focusing structure can easily output a broad beam, a collimated beam, or a beam ranging between the broad beam and the collimated beam according to user's needs to widely promote applications of the variable focus spotlight.
