Abstract:
1. A kind of improved structure of luminous umbrella having a flexible canopy, a shaft, a plate spring, a pressing switch, electric wire, a handle, a battery, a top column, ribs, linkages, the luminous umbrella comprising: linkage members on a slip ring assembly; rib members on a fixed collar assembly; and an umbrella handle illumination assembly, allowing light to be projected to an inner section of the canopy and to illuminate roads ahead for users, said linkage members on said slip ring assembly comprising a base, an LED assembly on a slip ring, insulation wire, multiple electric contacts on a slip ring and a transparent package, said base being made of materials with high heat dissipation capability to provide a heat dissipation function, said LED assembly on said slip ring and related circuit set being fitted on a surface of the base and protected with the transparent package, said surface of the base being composed of multiple annular surfaces of different diameters, said LED assembly on said slip ring and said insulation wire being installed on a top circumferential surface of said slip ring, wherein multiple slots are created on a middle circumferential surface of said slip ring for installation of said linkages as well as for heat dissipation, said heat dissipation function being provided at least by a bottom circumferential surface of said slip ring and a holding surface of said slip ring, said LED assembly on said slip ring comprising multiple sets of illumination emitter of LED and circuits linked together via a combination of series and parallel connections, wherein two end points of the circuit on said LED assembly on said slip ring connect to electric contacts on said slip ring, which are further connected with electric contacts on said fixed collar to form a circuit switch, the flexible canopy can be opened and closed with said linkage members on said slip ring assembly sliding up and down along the shaft, wherein light of the illumination emitter of LED is projected to an inner section of the flexible canopy when said circuit is activated, said rib members on said fixed collar assembly comprising a base, a LED assembly on said fixed collar, insulation wire, multiple electric contacts on said fixed collar and transparent package, said base being made of materials with high heat dissipation capability to offer the heat dissipation function, said LED assembly on said fixed collar and related circuit set being fitted on a bottom circumferential surface of said fixed collar and protected with the transparent package, said surface of the base being composed of multiple annular surfaces of different diameters, wherein multiple slots are created on a middle circumferential surface of said fixed collar for installation of said ribs, on which the flexible canopy can be fitted, said multiple slots also providing said heat dissipation function, said LED assembly on said fixed collar being composed of multiple sets of illumination emitter of LED and circuits linked together via a combination of series and parallel connections, wherein two end points of the circuit on said LED assembly on said fixed collar connect to electric contacts on said fixed collar and wire contacts, which are further connected with electric wires, said electric contacts on said fixed collar being used to connect to said electric contacts on said slip ring to form a circuit switch, wherein light of the illumination emitter of LED is projected to the inner section of the flexible canopy when the circuit is activated, said umbrella handle illumination assembly comprising a base, LED assembly, insulation wire, wire contact and transparent package, said base being made of materials with high heat dissipation capability to provide the heat dissipation function, wherein a surface of the base is composed of multiple annular surfaces of different diameters, wherein a top circumference surface is used for connection with the handle and heat dissipating fins are fitted on a middle circumference surface to provide said heat dissipation function, said LED assembly and said insulation wire are fitted on a bottom circumference surface, said LED assembly being composed of multiple sets of illumination emitter of LED and circuits linked together via a combination of series and parallel connections, wherein two end points of the circuit on said LED assembly connect to wire contacts, which are further connected with electric wires, wherein light is able to illuminate the roads ahead for users when the circuit is activated, said electric contacts on said slip ring coming into contact with said electric contacts on said fixed collar to form a closed-loop circuit when the umbrella is opened, the circuit being activated and the LED illumination device lighting up to project light to the inner section of flexible canopy and illuminating the roads ahead for users when the pressing switch is in a closed state, the circuit being an open circuit and said circuit not being activated when the umbrella is closed.
