DETAILED DESCRIPTION OF THE EMBODIMENTS

(15) With reference to FIGS. 1-12, the invention discloses a novel LED lamp string and a novel hose lamp applying the lamp string. The hose lamp is formed by a front connector 50, a tail plug 60, a hose 30 and at least one serial lighting LED lamp string 1 arranged in a through slot 35 of the hose 30. Two main wires 32 and 32′ are plastic-packaged on the hose 30, and connection wires connected with two ends of the serial lighting LED lamp string 1 are respectively connected with the corresponding main wires 32 and 32′.

(16) Wherein, the LED lamp string is a serial lighting LED lamp string 1, and the serial lighting LED lamp string 1 is formed by serial connection of a plurality of connection wires 10 wrapped by insulation films and a plurality of LED lighting chips 11 respectively welded between adjacent connection wires 10.

(17) With reference to FIGS. 5, 6 and 7, each LED lighting chip 11 comprises a chip body 12 and a wiring bottom plate 13 for fixedly arranging the chip body 12. The lower end surface of the wiring bottom plate 13 is straight and flat, and is provided with two lower end surface electrifying welding areas 13′. Specifically, a welding process can be performed by an elargol material (silver plastic). Block pins 10′ facing the outside are formed at the tails of the front ends of the connection wires 10. The block pins 10′ can be formed by bending or cutting in a process of machining and disconnecting a whole connection wire. And each LED lighting chip 11, the welded points of the connection wires 10 at two corresponding sides thereof and the corresponding block pins 10′ are tightly wrapped and plastic-packaged by small insulation plastic bodies 5.

(18) Of course, the block pins 10′ can be preferably formed by clamps or other devices after the connection wire is cutoff. For example, with reference to FIGS. 8 and 9, the front ends of the connection wires 10 are flattened by a die, and the block pins 10′ with cake-like clamping sections can make the structure of lamp string more fixed.

(19) Also with reference to FIGS. 10 and 11, the front ends of the connection wires 10 at two sides pass through the block pins 10′ of the clamping sections formed by winding and bending. They may pass through the block pins 10′ with the clamping sections formed by winding and bending up and down as FIG. 10, and may pass through the block pins 10′ with the clamping sections formed by winding and bending horizontally as FIG. 11. Of course, the block pins can be wound and bent by other angles instead of a horizontal and up-and-down manner, and due to these manners, the lamp structure can be fixed well. The adopted structure manner that the block pins are provided with the clamping sections formed by flattening or winding and bending is a very preferable technical means for solving the technical problem of the invention.

(20) Preferably, extending sections for connecting the wires 10 with the LED lighting chips 11 are downward sloped, and form slope sections 18.

(21) More than one half of the slope section is wrapped by the small insulation plastic body 5, so the bottom is more tightly wrapped.

(22) Of course, the extending sections for connecting the wires 10 with the lighting chips 11 are straight as shown in FIG. 12.

(23) Wherein, the connection wires 10 wrapped by insulation films are enameled wires.

(24) Preferably, the LED lighting chips 11 are strip-shaped, the long ends thereof and the lamp string are in the same direction, and the LED lighting chips are more compact in structure, and more firm and reliable when being stressed.

(25) Preferably, the front ends of the connection wires 10 wrapped by the insulation films to be welded on the same lighting LED chips 11 go deep into and get close to the straight and flat center of the lower end surface of the wiring bottom plate 13, so as to achieve the aim of being tightly wrapped by the small plastic body 5, and the two front ends are still insulated without conduction.

(26) Of course, the above embodiments are not limitations to the invention, and other equal technical schemes should be in the protection scope of the invention.
