Abstract: The present invention relates to a rope light, comprising: a hose which is provided with a hose body having an outer wall surface and an inner wall surface and a hose channel surrounded by the inner wall surface of the hose body; two bundles of conducting wires embedded in the hose body between the outer wall surface and the inner wall surface, and separated from each other and extending along a length direction of the hose channel; a plurality of light-emitting elements being electrically connected between the two conducting wires and being disposed within the hose channel; and a set of strengthen wire being embedded in the hose body between the outer wall surface and the inner wall surface, and the set of strengthen wire being separated from the two bundles of conducting wires and extending along a length direction of the hose channel.

Abstract: A decorative lighting device, comprising: an illuminating unit; and a light-transparent housing accommodating the illuminating unit, an inner surface of the light-transparent housing having a plurality of optical microstructure elements which refract light emitting from the illuminating unit within an incident angle to emit toward outside of an outer surface of the light transparent housing, the plurality of optical microstructure elements being formed on the inner surface of the light-transparent housing by a position allocation of the optical microstructure elements on the inner surface of the light-transparent housing such that a planar light pattern surrounding the illuminating unit is formed, the optical microstructure elements being provided spreading over the inner surface of the light-transparent housing. Thus, the decorative lighting device of the present invention illuminates special pattern of light.

Abstract: The present invention provides a strengthened decorative light wire. The decorative light wire is for electrically connecting a plurality of lamps. Each decorative light wire comprises a plurality of untwisted conductor wires, an external insulating sheath wraps around the plurality of conductor wires and one or more flat elongated strengthening sheets disposed between a inner surface and a outer surface of the external insulating sheath by enabling the flat elongated strengthening sheet/s to fully or partially, within the external insulating sheath, surround the conductor wires.

Abstract: Disclosed is a wire structure for a decorative light string; a wire body used in the entire light string set is adopted with an insulating outer jacket covering a bundle of metal conductive filaments and a bundle of light and nonconductive non-metallic filaments at the same time to form an wire structure with a diameter close to the one of a wire of a general conventional decorative light string, thereby allowing the wire to increase the tensile strength substantially at a lower cost only increasing the weight and diameter thereof a little bit so as to increase the practicability of the wire of the decorative light string of the present invention.

Abstract: A novel LED lamp string is provided whose LED lamps are protected from current/voltage fluctuation. The gist of the present invention lies in the configuration of a number of resistors series-connected to the LED lamps along the cable of the LED lamp string. With the resistors, the current and voltage along the cable are stable with no sudden high or low, and therefore the LED lamps have longer operational lives.

Abstract: The present invention proposes a LED Christmas light, using an LED bulb with four connection pins to insert in a soft core configured with four slots allowing the four connection pins to be passed through and bended configured on the bottom thereof, and the soft core being inserted in a soft head with four V-typed convex plates in pairs face-to-face and extended to the bottom face thereof configured on the inside thereof, where an engagement partitionment groove is formed between each two adjacent convex plates in the soft head, allowing four metal conducting sheets with a conducting wire to be respectively engaged therewith, thereby allowing one LED Christmas light unit to use an LED bulb with a light source of more than four colors.

Abstract: The present invention provides a coupling structure of a flexible core and a flexible base of a Christmas light string, which is applicable to a Christmas light string, in which a Christmas light is formed of a combination of a flexible core, a flexible base, an LED, and electrical wires and multiple Christmas lights are combined to form a Christmas light string. The features of the present invention are that a flexible core has a bottom on which two bearing seats are formed to support two terminal pins of an LED and having bottom edges in which folding notches are formed in such an arrangement that one is relatively high while the other is relatively low, whereby the two terminal pins of the LED, after being folded about the bearing seats, both provide an extended exposed portion for engagement with the conductive pad of the corresponding electrical wire.
