Light-emitting diode (LED) projection lamp with adjustable light range

In order to solve the technical problem that different lighting requirements are difficult to meet in the same range, an adjusting mechanism is arranged, when the irradiation range of the lamp needs to be adjusted, a worm is rotated to drive a worm wheel to rotate, and the worm wheel rotates to drive a threaded rod to rotate, so that the illumination range of the lamp is adjusted. The threaded rod rotates to drive the lens support to move, the lens support moves to drive the concave lens to move, and the concave lens moves, so that the distance between the concave lens and a bulb in the lampshade can be adjusted, the path of light passing through the concave lens is changed, and the size of light spots generated when the light passes through the concave lens is changed. Therefore, the adjustment operation of the irradiation range is completed. 一种带有灯光范围可调式LED投光灯，为了解决在同一范围内难以满足不同的照明需求的技术问题，本发明通过设置调节机构，可以实现在需要对灯具的照射范围进行调节时，通过转动蜗杆带动蜗轮进行转动，蜗轮转动带动螺纹杆转动，螺纹杆转动带动透镜支架进行移动，透镜支架移动带动凹透镜进行移动，凹透镜进行移动，即可实现对凹透镜和灯罩内部灯泡之间的间距调节操
