The invention relates to the field of welcome lamps, in particular to a welcome lamp and a control method thereof. The welcome lamp comprises a first projection part, a first light source assembly and a second light source assembly which are rotationally arranged, and a plurality of first films which are circumferentially distributed at intervals are arranged on the first projection part and can sequentially rotate to a first station of the first projection part. Light emitted by the first light source assembly can project patterns contained on the first films to the imaging area to form projection, the multiple first films on the first projection piece sequentially rotate to the first station for projection, and a picture formed in the imaging area shows the flow field dynamic effect. Light emitted by the second light source assembly can also irradiate the imaging area to form background light. Therefore, in the projection process, the projection content can be kept in a normally-on state through the second light source assembly, so that the problem of screen flashing during projection is avoided, and the dynamic projection effect and smoothness are improved.
本申请涉及迎宾灯领域,尤其是涉及一种迎宾灯及其控制方法。迎宾灯包括旋转设置的第一投影件、第一以及第二光源组件,第一投影件上设有多个呈圆周间隔分布第一菲林片,多个第一菲林片能够依次地旋转至第一投影件的第一工位处。第一光源组件发出的光线能过将第一菲林片上包含的图案投射至成像区域以形成投影,随着第一投影件上的多个第一菲林片依次旋转至第一工位进行投影,成像区域形成的画面将呈现流场地动态效果。第二光源组件发出的光线也能够照射至成像区域,以形成背景光。因此,在投影过程中,通过第二光源组件能够使投影内容保持常亮状态,从而避免投影时出现屏闪的问题,以提高动态投影效果和流畅性。
