Description

Technical Field

[0001] The utility model belongs to the technical field of exhibition facilities, and in particular relates to an adjustable LED moving head car exhibition light. Background Art

[0002] At auto shows, in order to create lighting effects and lighting atmosphere, it is usually necessary to install lighting facilities on the booth trusses and stand trusses. With the development of technology and the increasing requirements for lighting facilities in exhibition scenes, traditional fixed lighting facilities can no longer meet the use requirements. People hope that auto show lights have more controllable actions to create better lighting effects and lighting atmosphere, and build better exhibition display effects.

[0003] The moving head lights currently used in auto show scenes are usually equipped with a bracket assembly, and the main part is hingedly connected to the bracket assembly and equipped with a locking assembly. After the auto show lights are installed on the high-position truss, the lamp is manually adjusted to the appropriate direction according to the direction of the on-site lighting, and the locking assembly is used to lock the posture of the lamp. However, the "moving head" of this type of moving head auto show lights only means that the initial posture can be manually adjusted, and the moving head cannot be flexibly adjusted at any time during the exhibition as needed, which limits the lighting effect at the exhibition site. Therefore, it is necessary to develop and design a new type of moving head auto show lights. Utility Model Content
