Abstract

The invention discloses a light source moving device, which is used in a flashlight. The light source moving device sequentially includes a light source, a light source fixing plate, an elastic member, an electromagnet and an electromagnet fixing plate along the direction of the optical axis. The light source is fixed on the light source fixing plate. The iron is fixed on the electromagnet fixing plate, and the elastic piece is arranged between the light source fixing plate and the electromagnet fixing plate; when the electromagnet is energized and has magnetic force, the electromagnet attracts the light source fixing plate, and the elastic piece is compressed on the light source fixing plate and fixed by the electromagnet between the plates; when the electromagnet is powered off, the light source fixing plate is relatively far away from the electromagnet fixing plate under the elastic force of the elastic member. The flashlight is simple and compact. And by pressing the switch button, the function of quickly adjusting the range of the flashlight's irradiation angle, brightness and focal length is realized, and the operation is simple and fast, and the flashlight with the light source moving device is also disclosed.

Description

technical field [0001] The invention relates to the lighting field, in particular to a light source moving device and a flashlight with the light source moving device. Background technique [0002] In homes, workplaces and entertainment occasions, flashlights are often used as a movable light source. Existing flashlights can be divided into two types according to their focusing functions, one is automatic focusing, but the flashlights with automatic focusing are generally larger in size and complex in structure. There is another kind of manual focusing. The existing manual focusing devices generally need to be twisted and rotated by hand to achieve the purpose of focusing. The conversion of this adjustment structure is relatively slow, and the one-handed operation is difficult to realize, and the operation is cumbersome and laborious. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a light source moving device ...
