Abstract

The invention discloses a focusing lamp comprising a front lamp cap, a rear lamp body and a focusing device. The focusing device is arranged between the lamp cap and the lamp body and rotates to drive a light source in the lamp cap to move back and forth for focusing. The invention realizes the focusing function by changing the axial position of a light source corresponding to a reflector so thatthe exterior size of the lamp can be reduced, and the manufacture cost of a lamp shell material can be decreased without adjusting the position of the reflector. Meanwhile, the exterior size of the lamp is reduced to effectively improve the transportation capability.

Description

technical field [0001] The invention relates to a lamp, in particular to a lamp with a focusing device. 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. The focusing device changes the focus state of the light by moving the reflector, that is, the focusing function is realized by changing the relative distance between the reflector and the light sou...
