Description

Technical Field

[0001] The utility model relates to the technical field of spotlights, in particular to an adjustable spotlight. Background Art

[0002] Spotlights are commonly used focusing devices in photography. When using spotlights, Fresnel spotlight kits are usually installed to adjust the illumination range of the emitted light.

[0003] In order to facilitate the adjustment of the range of light exposure, a light shield is provided on the outside of the Fresnel spotlight set to limit the area and range of illumination.
