Abstract

The invention discloses a focusing device of a lamp, which comprises a moving piece, wherein the moving piece is fixedly connected with a lamp holder; the adjusting piece is sleeved outside the moving piece and matched with the moving piece; and the adjusting piece rotates to drive the moving piece to move forwards and backwards so as to make the lamp holder extend forwards or back away for focusing. The adjusting piece is matched with the moving piece, and the adjusting piece rotates to drive the moving piece fixedly connected with the lamp holder to move forwards and backwards to make the lamp holder extend forwards or back away so as to change the axial position of a light source on a light reflector and realize the function of focusing. The structure reduces the appearance volume of the lamp and reduces the manufacturing cost of a shell material of the lamp. The appearance volume of the lamp is reduced, which can effectively improve the transportation capacity at the same time.

Description

technical field [0001] The invention relates to a focusing device, in particular to a focusing device for a lamp. Background technique [0002] Lamps are often used in daily work and life. With the development of science and technology, high-brightness light sources and high-focus lamps have been developed, so that lamps can meet the needs of different users. For example, when working at night, the searchlight light is often focused and projected to the working range to enhance the brightness of the working range; when the flashlight needs to illuminate a certain target object at a fixed point, it can be adjusted to increase the brightness of the target object, etc. . At present, in order to realize the focusing function of the lamps, a focusing device is generally installed on the lamps, and the focusing state of the light is changed by moving the reflector, that is, the focusing function is realized by changing the relative position between the reflector and the light sou...
