摘要： An optical system of an LED variable-focal-length imaging lamp comprises an LED light source module (1), a light-gathering assembly (2), a cutting assembly (3) and a zoom lens group that are successively mounted along a light path. Geometric centers of these components are collinear with a primary optic axis A, and a focus F1 of the light-gathering assembly (2) coincides with a focus F2 of the zoom lens group. The zoom lens group comprises a first zoom lens (4), a diaphragm (5) and a second zoom lens (6). The first zoom lens (4) and the second zoom lens (6) can move back and forth along the primary optic axis A to achieve a variable focal length, and the diaphragm (5) is provided between the first zoom lens (4) and the second zoom lens (6) and has an adjustable clear aperture. Such an optical system may be widely applied in an LED variable-focal-length imaging lamp, to replace an existing LED fixed focal-length imaging lamp with different angles and high-consumption halogen-bubble light source imaging lamp. By designing a diaphragm (5) in a zoom lens group, off-axis aberration can be effectively alleviated, off-axis stray light can be reduced to pass through, and a clearer image can be formed.
摘要翻译：一种LED可变焦距成像灯的光学系统包括沿着光线依次安装的LED光源模块（1），聚光组件（2），切割组件（3）和变焦透镜组路径。这些部件的几何中心与主光轴A共线，并且聚光组件（2）的焦点F1与变焦透镜组的焦点F2重合。变焦透镜组包括第一变焦透镜（4），光圈（5）和第二变焦透镜（6）。第一变焦透镜（4）和第二变焦透镜（6）可以沿着主光轴A前后移动以实现可变焦距，并且隔膜（5）设置在第一变焦透镜（4）和第二变焦透镜（6）并且具有可调节的清晰光圈。这种光学系统可以广泛应用于LED可变焦距成像灯中，以替代现有的具有不同角度的LED固定焦距成像灯和高消耗卤素气泡光源成像灯。通过在变焦透镜组中设计光阑（5），可以有效地减轻离轴像差，可以减少离轴杂散光通过，并且可以形成更清晰的图像。

摘要： A camera lens module in which an optical system is configured to include five sheets of lenses is provided. In the camera lens module, first, second, third, fourth and fifth lenses are sequentially arranged from an object side, and the first lens performs a zooming operation while moving along an optical axis. Accordingly, the optical system is configured to include five sheets of lenses for performance of a zooming operation and to allow only the first lens to perform the zooming operation, so that it is possible to manufacture a high-resolution optical system in a compact size and to perform the zooming operation at a high speed.
