The present invention is a supporting structure for decorative Christmas lights. The main structure of the present invention is a center pole with a fixed hub at the top, and a movable hub, which can move along the center pole. A plurality of hanging bars are connected to the fixed hub at one end, and connected to the supportive struts at the other end. The other ends of the supportive struts are hooked to the movable hub. This forms an umbrella-like structure. By moving the movable hub along the center pole, the structure can be easily opened up or display or fold to save storage space. It could also form a multi-level structure and a number of variations. The lights can be hanged, or clipped to the structure. When the structure is implemented with hollow tubes, the lights can be inserted inside the tubes. The different styles of attaching lights to the supporting structure can be combined to achieve various desirable visual effects.
