Abstract:
A rope light structure comprising a plurality of light bulbs connected in series to form light bulb sets, positive and negative pole terminals of the light bulb sets are connected in parallel to core wires on two sides, the core wires on two sides being covered by an inner PVC layer, the light bulbs sets disposed at a hollow area of the inner PVC layer, an outside of the inner PVC layer is further covered by an outer PVC layer; a plurality of first arcuations disposed on an inner edge at the hollow area of the inner PVC layer to form heat sink spaces to increase a useful life of the light bulb sets; and, a plurality of second arcuations disposed between the inner PVC layer and the outer PVC layer to augment a brightness of the rope light to thereby create multiple variations of retracting light, to facilitate heat dissipation and to increase the useful life of the light bulbs.
