[0002] As an important part of modern lighting equipment, spotlights are widely used in various occasions such as home, business and industry. Existing spotlights usually adopt a fixed focal length design, that is, the distance between the light source lamp panel and the light-transmitting mirror is fixed, and the light diffusion focal length cannot be adjusted according to different lighting needs, resulting in a single coverage range and illumination effect of the light, and cannot flexibly adapt to the lighting needs of different environments.

[0003] Since the distance between the light source panel and the light-transmitting mirror cannot be adjusted, the illumination range of the spotlight is fixed and difficult to adjust according to the needs of specific scenes. For example, in a large space that requires wide-angle lighting, a fixed-focus spotlight may not provide sufficient coverage; and in a scene that requires concentrated light, a fixed-focus spotlight may appear too scattered.

[0004] Since the diffusion angle of the light cannot be adjusted, the light may not be focused on the specific area that needs lighting, resulting in light waste and reduced light utilization efficiency.
