Abstract

The invention provides a focusing light source and a focusing device with the focusing light source. The focusing light source comprises: a base; a lamp body, which is located above the base; and a focusing assembly, which is arranged on the base, wherein the focusing assembly comprises a driving device, a lens and a transmission part, the transmission part is movably arranged on the base, the lens is located between the lamp body and the base, and the driving device drives the lens to move in the axial direction of the base through the transmission part. According to a technical scheme in the invention, the problem that the adjustment error of an illumination area of the focusing light source is large in the prior art is effectively solved.

Description

technical field [0001] The present invention relates to the technical field of lighting, in particular to a focus-adjusting light source and a focus-adjusting device having the same. Background technique [0002] With the development of science and technology, there are various types of lamps and lanterns. At present, in order to meet the needs of users in different situations, it is necessary to change the illuminated area of ​​the lamp. [0003] In the related art, the distance between the light source and the table is adjusted through the structural rotating shaft of the lamp, or by means of pulleys, so as to realize the purpose of adjusting the illumination area. The above-mentioned adjustment methods all need to be adjusted manually, and the error is relatively large, and it is difficult to ensure the required spot area during adjustment. Contents of the invention [0004] The main purpose of the present invention is to provide a focus-adjustable light source and a ...
