The high power lamp string devices

Technical field

The utility model relates to a kind of high power lamp string devices, refers in particular to a kind of lamp string devices that utilizes light-emitting diode to form.

Background technology

LED (light-emitting diode, light-emitting diode) has that volume is little, low power consumption, long service life, reaction speed reach characteristics such as cold light is luminous soon, meets environmental protection and recyclable, so there is not general fluorescent lamp can cause the problem of mercury pollution to environment.In addition, light-emitting diode is to utilize DC driven thereby regulation and control easily, and can reduce the complexity of circuit design, therefore is widely used in already on the various electronic products.

Please refer to Fig. 1, is U.S. Patent number the 6th, 830, No. 358 disclosed a kind of LED light string devices, and the decorative chain of the multiple occasion of its Chang Zuowei for example uses to increase Christmas spirit when the Christmas festival celebration.As shown in the figure, the structure of LED light string device 10 comprises a plug 12, and its external power supply changeover device 14 utilizes power supply changeover device 14 that alternating current is changed into direct current and is delivered to two LED tandems 16 again, and a tail slotting 18 can use for another plug grafting.Yet,, tend to destroy the aesthetic feeling of whole LED serial because power supply changeover device 14 has certain volume.

In view of this, the utility model provides a kind of more perfect lamp string devices, to overcome above-mentioned disappearance.

The utility model content

A purpose of the present utility model provides a kind of high power lamp string devices, and it makes whole lamp string devices more succinct with being located in the power supply changeover device during plug and tail insert, and can improve the overall aesthetic that decorative effect avoids destroying lamp string devices.

Another purpose of the present utility model provides a kind of high power lamp string devices, and it is to utilize a plurality of light-emitting diodes to form the lamp string structure, has high efficiency and can save electric power again.

According to high power lamp string devices disclosed in the utility model, comprise a plug, its have a conduction inserted sheet group and in establish one first power supply changeover device and will convert a High Level DC Voltage to through conducting electricity an alternating voltage of inserted sheet group thus, one tail is inserted, establish a conducting strip group and a second source transducer in it, reception converts thereof into a low dc voltage through conducting electricity the alternating voltage of inserted sheet group thus, at least one LED serial, the one end connects first power supply changeover device to receive this High Level DC Voltage, the other end then connects the second source transducer to receive this low dc voltage, makes the LED serial conducting.

Compared with prior art, the utlity model has following advantage:

The utilization of the utility model high efficiency lamp string devices is arranged at power supply changeover device in plug and tail insert, and can avoid destroying the overall appearance of lamp string devices again so that whole lamp string devices is more succinct.
