Summary of the invention

This case inventor is because above-mentioned known Christmans light string is constructed the restriction that employed decorations light fixture has solid shape, flashing light color and working voltage, change the shortcoming that some special lamp decorations that meet time and occasion use and be difficult to follow one's inclinations: the inventor has studied a kind of applicable various lamp string use that is plugged in, and the Christmas lights that alterating and direct current all can be shared structure.

Main purpose of the present utility model aims to provide the Christmas lights structure that a kind of alterating and direct current can be shared, be on lamp decoration, to add a circuit board with rectification and voltage stabilizing, current stabilization function, make this lamp decoration can be plugged in use in the lump on arbitrary commercially available Christmans light string, and promote the use effect and the decorative effect of this lamp string.

Another purpose of the present utility model aims to provide the Christmas lights structure that a kind of alterating and direct current can be shared, and it has the function that the polychrome flash of light changes, and can further promote the decorative effect of this lamp string.

In order to achieve the above object, the utility model mainly is connected with a circuit board between the LED lamp in this lamp decoration structure and the connection-peg, at least have a bridge rectifier and a voltage stabilizing feedback circuit etc. on this circuit board, power supply is connected to two inputs of bridge rectifier respectively by two leads on the connection-peg, the DC output end of this bridge rectifier then is connected to the voltage stabilizing feedback circuit, is connected to the LED lamp again to form complete loops; In addition, LED lamp wherein must be three-color LED light.

When using according to above-mentioned structure, the power supply of its input must be in circuit board the rectification of bridge rectifier, no matter the power supply of this bridge rectifier input is that alternating current or direct current all can and have fixing both positive and negative polarity output by its acceptance again, and by the direct current of bridge rectifier output again through the effect of voltage stabilizing feedback circuit, to keep it stable voltage and electric current output are arranged, though according to and can make the input these Christmas lights power supply be direct current or alternating current, all can be and can light the LED lamp through the conversion of this circuit board, to reach the use effect and the purpose of expection.

The specific embodiment

Now cooperate graphic detailed description as back for an embodiment:

At first, as shown in Figures 1 and 2, alterating and direct current of the present utility model can be shared Christmas lights structures, this lamp decoration structure mainly has one and is connected in the LED lamp 20 of the special-purpose connection-peg of Christmas lights 10 rear ends, uses (as shown in Figure 5) and must borrow connection-peg 10 that this lamp decoration structure is plugged in the lump on the commercially available Christmans light string with corresponding bulb gang socket; It is characterized in that:

At least have a bridge rectifier 31 and a voltage stabilizing feedback circuit 32 etc. on this circuit board 30, after power supply is connected to two inputs of bridge rectifier 31 respectively by two leads 11 and 12 on the connection-peg 10, the DC output end of this bridge rectifier 31 then is connected to voltage stabilizing feedback circuit 32, is connected to LED lamp 20 again to form a complete load circuit.

As Fig. 2 and shown in Figure 4, LED lamp 20 wherein must be a kind of three-color LED light, this LED lamp 20 is to be packaged with a microcircuit plate 22 in transparent colloid 21, have red in these microcircuit plate 22 upper fixed, blue, the luminescence chip 23a of green three colors, 23b, 23c, and be fixed with a control chip 24 in microcircuit plate 22 bottom surfaces, when the anodal support 25 in this three-color LED light 20 is imported, when forming the loop by 26 conductings of negative pole support again, can see through program default in the control chip 24 and do effectively output, with

control luminescence chip

23a or 23b, 23C etc. are flicker or luminous in the lump in turn, and make the effect of these LED lamp 20 tool mixed light variable colors, can promote the decoration effect of this bulb itself.The transparent colloid 21 of this LED lamp 20 also can directly be made as the jewelry with special appearance or color again, or increases the lampshade 27 that the special appearance of tool is set implement (as shown in Figure 5) outside this LED lamp 20.

Again as shown in Figure 2, voltage stabilizing feedback circuit 32 wherein is to comprise by a long-pending PNP transistor 322 of receiving diode 321, three series connection being formed with the RC match circuit, and can borrow the back coupling load voltage be reached the effect of voltage stabilizing and current stabilization.Or as shown in Figure 3, it is that another of this voltage stabilizing feedback circuit 32 implemented illustration, is that voltage stabilizing feedback circuit 32 electrode input ends at Fig. 2 embodiment get and connect a PNP transistor 322 again, and can reaches the effect of voltage stabilizing and current stabilization equally.

When using according to above-mentioned tectonic association, when using in the lump in the gang socket 41 that must borrow connection-peg I0 this lamp decoration structure to be plugged in commercially available Christmans light string 40 (as shown in Figure 5), 30 bridge rectifier 31 rectifications in circuit board earlier of the power supply of its input, no matter causing the power supply of these bridge rectifier 31 inputs is that alternating current or direct current all can and have fixing both positive and negative polarity output by its acceptance, and get again effect through voltage stabilizing feedback circuit 32 by the direct current of bridge rectifier 31 output, so that the output of its electric current can be kept stable voltage and electric current, but and available energy is lighted the LED lamp 20 that it connects; According to and the utility model in use, the purpose that can peg graft and use with the Christmans light string of the power supply that uses direct current or alternating current, and convenience and mobility that tool uses.In addition, LED lamp 20 in the utility model is to have the polychrome flashing function for three-color LED light, and the profile of this LED lamp 20 also can be made into special appearance, or covers with the decorative lampshade 27 of spherical or special appearance, with practicality and the effects such as novel sense, interest that more can promote this product.

Comprehensive the above, simple structure of the present utility model and can reach and arbitrarily be plugged in effect and the purpose of using in the lump on the Christmans light string that uses direct current or alternating current.
