[0014] In various embodiments described herein, a self-coiling light structure is designed for ease of deployment and storage, providing a solution to the common problem of tangled decorative lights. By enabling automatic retraction and compact storage, this system reduces setup time and enhances usability and can be used for a wide range of lighting applications.
[0015] FIG. 1 illustrates a side view of the self-coiling light structure in accordance with an embodiment of the invention. As shown, coil la consists of a flexible elongate body, which may comprise wire, rope, plastic, or a combination of these materials. The elongate body is configured to transition between a coiled and expanded state, allowing for compact storage and efficient deployment. A power-conducting element lb extends along the length of the elongate body, supplying electrical power to a plurality of LED lights 1c that are positioned at standard intervals. A male power end le and a female power end If enable electrical coupling to a power source or interconnection with additional light structures. A protective outer shell 1g encases at least a portion of the elongate body, enhancing durability and resistance to environmental factors such as moisture, temperature fluctuations, and mechanical stress. In some embodiments, the outer shell is designed for outdoor use, offering protection against UV exposure, rain, and extreme temperatures.
[0016] FIGS. 2 and 3 illustrate the self-coiling light structure in its retracted and extended states, respectively. FIG. 2 depicts coil la in a retracted state, where the shape-memory material within the elongate body biases the structure toward the coiled (or retracted) configuration. FIG. 3 shows the structure in its extended position, where an external force has caused the elongate body to stretch to its full length. Upon the removal of this external force, the structure automatically returns to its coiled state, preventing the structure from tangling and facilitating storage of the structure.
[0017] FIG. 4 is an axial view illustrating the internal components of the self-coiling light structure. The structure includes an outer shell 4a, which serves to protect internal components from environmental and mechanical damage. A power-conducting material 4b extends along the length of the structure, ensuring continuous power supply to LED lights 4d, which are positioned at regular intervals.
