Abstract: A colorful rope light characterized by colored transparent cladding interposed between a lighted core and an extruded clear cover. The cladding can include selected lengths of tubing, including shrink tubing and longitudinally slit tubing, as well as wrapped strips of transparent colored material. The cladding can also be provided with various color patterns. One or more units of the rope light can each have multiply colored portions, facilitating a wide variety of effects.

Abstract: A colorful decorative light is disclosed. The colorful light includes a length of flexible core provided with mini-bulbs and wires electrically connecting to the mini-bulbs, and a substantially transparent outer covering encasing the core. In addition, a colorful and transparent cladding is arranged between the core and the outer covering, in order to provide a fancy decoration.

Abstract: A decorative optical fiber includes a flexible thread made of an optical medium, a substantially transparent cladding encasing the flexible thread of the optical medium, and a protective covering encasing the cladding. The cladding is made of a material having a lower index of refraction than that of the optical medium, and the protective covering is substantially transparent and has a rugged outer face.

Abstract: An optical fiber tube includes a core material having multiple nylon filaments twisted with each other in a helical manner, a plurality of single strand optical fibers mounted around the core material and twisted with the core material in a helical manner, a tubular protective film mounted around the plurality of single strand optical fibers, and a plastic sleeve mounted around the protective film.

Abstract: A lamp connector includes a terminal base connected between two opposed ends of adjacent lamps and an enclosure receiving the two opposed ends and the terminal base. The enclosure is composed of a first part and a second part opposed to each other. The first part of the enclosure has a cross section shaped as an "L" and the second part of the enclosure has a cross section shaped as an inverted "L" so as to define a cuboid space therein for receiving two adjacent lamps with rectangular cross sections. The first part and the second part further have a series of ribs extending from an inside wall thereof for fastening the two opposed ends of the lamps. Also, each lamp has two series of bulbs arranged in a manner that the bulbs of one series are staggered with those of the other series so that it provides a subdued light effect under the control of a control circuit.
