In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structure chart of LED of the present utility model;
Fig. 2 is the circuit diagram of LED string of the present utility model;
Fig. 3 is the circuit diagram of the utility model with the LED string of plug and socket;
Fig. 4 is the circuit diagram that the utility model connects the LED string of light-controlled transformer.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, LED string of the present utility model adopts inner concave shape LED 1, and described LED 1 has two lamp bases, 5, two lamp bases 5 and is connected to the wire 4 be connected with adjacent LED lamp 1.For ensureing the seal of LED 1, LED pin 5 is socketed with lampshade 3 with the junction of wire 4, and described lampshade 3 is closed shaping by injection machine, lampshade 3 one end seals up the connecting portion of LED 1 base and lamp base 5, and the other end seals up the outer wall of two wires 4.
As a preferred embodiment, between two LED pin 5, be also provided with insulated column 2, the short circuit caused with the contact between avoiding due to lamp base 5.Described insulated column 2 top is connected with the base of LED 1, and the lower end of described insulated column 2 is provided with the draw-in groove holding wire 4.
As shown in Figure 2, described LED 1 adopts the mode of first rear series connection in parallel to be connected in series.As a preferred embodiment, described LED string comprises 10 LED groups, and 10 LED groups are connected successively, and each LED group includes 5 LED, 1,5 LED 1 composition LED parallel with one another groups.Adopt this connected mode, reduce the all-in resistance coefficient of lamp string, make current loss less, compared with traditional LED lamp series system, not only overcome because the self-resistance coefficients such as LED are larger, produce voltage distribution inequality after series connection, cause the phenomenon of lamp string brightness irregularities, and significantly can also save electric wire.The lamp string of 10-100 LED can save 50-60% electric wire, and the lamp string of 100-1000 LED can save 40-50% electric wire.According to actual needs, LED group can be set to 11,12 or more by those skilled in the art, and LED can be set to 6,7 or more according to actual needs.
