Abstract

The invention provides a lens focusing structure and a lamp, belonging to the technical field of lighting. The lens focusing structure comprises a shell, a first lens and a second lens, wherein the first lens and the second lens are arranged inside the shell; the axis centers of the first lens and the second lens are at the same straight line; an adjusting rod is arranged along the parallel direction of the axle of the first lens and the second lens inside the shell; the adjusting rod comprises an adjusting part with an external thread and a knob part which drives the adjusting part to rotate; the first lens is fixed on a bracket; the bracket is in threaded connection with the adjusting part; and when the adjusting rod rotates, the bracket moves along the external thread of the adjusting part axially and drives the first lens to move horizontally along the axis direction of the second lens. According to the lens focusing structure, the first lens is driven by the threaded cooperation of the bracket and the adjusting rod to make straight line movement so as to change the focusing state of the light passing through the first lens and the second lens; and the lens focusing structure is easy to manufacture and assemble, the focusing operation is convenient, when being used in the lamp, the lens focusing structure is convenient to repair and change, and therefore, the market competitiveness of the lamp is increased.

Description

technical field [0001] The invention belongs to the technical field of lighting, and more specifically relates to a lens focusing structure and a lamp adopting the focusing structure. Background technique [0002] Lens imaging technology has been used in various occasions. In many occasions, the lens needs to be adjusted to obtain light with variable vergence and divergence, such as in projection lamps. In the existing projection lamps, the focus adjustment of the lens is to convert the rotary motion into a linear motion by opening a spiral groove and a linear groove on the lamp to achieve the purpose of focal length adjustment. However, the existing focusing structure is complicated and the manufacturing The cost is high, the assembly and maintenance are difficult, the efficiency is low, and the focusing operation is not easy, and the practicability is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the ...
