The present invention is a rope light structure, wherein several sets of light bulbs in series connection are disposed inside the hollow area of a transparent inner layer of polyvinyl chloride (PVC hereafter), the positive and negative pole terminals of the said several sets of light bulbs are connected in parallel with two core wires on two sides, an inner edge of transparent inner PVC layer is mounted with several arcuations, an outer layer thereof is covered by a transparent outer PVC layer disposed with several arcuations, thereby several arcuations are formed between the inner and the outer layers to define heat sink space for the light bulbs to facilitate the heat dissipation of the light bulbs so as to increase useful life of the light bulbs, to augment the brightness of the rope light so as to make multiple variations of refracting light.
A rope light structure comprises of several light bulbs connected in series to form light bulb sets, the positive and negative pole terminals of several light bulb sets are connected in parallel to the core wires (power source) on two sides, the core wires on two sides are covered by an inner PVC layer, several light bulb sets are disposed at the hollow area of the inner PVC layer, the outside of the said inner PVC layer is further covered by an outer PVC layer;
