Description

Technical Field

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

[0002] Spotlights are lamps that use condensers or reflectors to focus light. Spotlights have a relatively simple light pattern, strong illumination, and a narrow illumination range, making it easy to focus on a specific area in the scene. Spotlights can be aimed in multiple directions and are not easily affected by weather conditions. They are mainly used in studios, stadiums, construction sites, parks, and other scenes.
