  • the lens assembly is driven by the lever 9 and then axially moves with the three connection posts 17 together along the axial direction, without deflection or deformation, so as to achieve desirable focusing consistency and a stable focusing structure.
  • the lever 9 drives, through the connection post 17, the lens assembly to axially move with respect to the light source assembly.
  • a pair of forces in opposite directions is applied on the lens assembly by the connection post 17 and the spring 8, ensuring that the distances from the LEDs 4 in the light source assembly to the lenses 1 corresponding to the LEDs 4 in a one-to-one manner consistently change in the focusing process, that is, achieving focusing consistency.
  • the focusing mechanism implements stable and fine focusing for the LED spotlight with high power, ensures evenness, desirable luminous efficiency, and high brightness of the light spots cast by the LEDs 4, and is appropriate for manufacturing of an LED lamp for a film and television with high power.
