Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:

Fig. 1 is the structural representation of ordinary lamps string.

Fig. 2 is the structural representation of the utility model LED lamp decoration device;

Fig. 3 is the circuit diagram of the surface-mounted integrated circuit of the circuit part in the utility model LED lamp decoration device.

The specific embodiment

The utility model is a kind of LED lamp decoration device that is used on the lamp string.As shown in Figure 1, be in series with a plurality of lamp sockets 2 on lamp string 1, each lamp socket can be installed a bulb 3.As shown in Figure 2, in LED lamp decoration device of the present utility model, comprising the connector 4 that is connected with lamp socket, this connector should be complementary with the lamp socket that is connected, and should comprise respectively that electricity gets an electric shock partly and the coupling of insulated part.Electricity gets an electric shock and partly is meant that connector is corresponding with the contact position of lamp socket, thereby can realize current lead-through; Insulated part is meant cooperating of shape and size between connector and lamp socket, and for example, existing lamp socket generally can be divided into screw socket or bayonet socket, and corresponding connector can be designed to screw socket or bayonet socket form, and its size should coincide, thereby guarantees the sealing and the security that connect.Connector extends derives first extension wire 5, and then is connected to a circuit part 6, and this circuit part comprises the surface-mounted integrated circuit that is used for rectification.Be connected on the lamp group 7 by second extension wire 8, lamp group 7 comprises a plurality of light emitting diodes again.

As shown in Figure 3, circuit part 6 of the present utility model comprises surface-mounted integrated circuit, is used for the High Level AC Voltage input is converted to low-voltage DC.In this integrated circuit, comprising the rectification circuit of forming by four diodes, Zener diode and electric capacity.At ac input end, it is in parallel again after four diodes are connected in twos, wherein an earth connection is derived at the public negative pole place of two diodes, and an output line is derived at the public anodal place of two diodes in addition, at an output Zener diode respectively in parallel and an electric capacity.In preferred embodiment of the present utility model, employed diode model is IN4007.Described Zener diode both end voltage is 3～6V, can select different voltage-stabiliser tubes to obtain different voltage, and the parameter of electric capacity described in the present embodiment is chosen as 100UF and 10V.
