Described lamp string is that one group of LED lamp is in series, described full-wave rectification conversion equipment comprises the part bridge-type rectifier that places the wiring board in attaching plug and the supply socket and be connected two commutation diodes compositions on each wiring board, and this two parts bridge-type rectifier is combined into complete bridge-type rectifier.

Described lamp string is combined by the connection in series-parallel of two groups of LED lamps at least, be provided with wiring board in described attaching plug and the supply socket, all be connected with the part bridge-type rectifier that two commutation diodes are formed on described two wiring boards, connect by two LED lamp lamp holders between adjacent lamp string with four line structures, also be connected with the part bridge-type rectifier that other two commutation diodes are formed between described adjacent lamps string, two groups of part bridge-type rectifiers in described attaching plug and the supply socket and the part bridge-type rectifier between each adjacent lamps string constitute the full-wave rectification conversion equipment of a complete AC-DC.

The maintenance and the replacing of LED lamp for convenience, the lamp holder of described LED lamp is split detachable assembly structure is set.

The shell of described LED lamp is to adopt the PS plastics of the strong transparency or the PE plastics of translucence (primary colors).

The three-phase type connected structure is all adopted in described attaching plug and supply socket.

Compared with prior art, the beneficial effects of the utility model are:

(1) the utility model decorated light string structure full-wave rectification conversion equipment, the fluctuation of voltage is reduced greatly, thereby make the lamp string no longer produce flickering, improved the reliability of LED lamp, brightness and service life, and at whole ac cycle, it is luminous to drive the lamp string, be about to alternating current (AC) and be converted to direct current (DC), thereby greatly improved the utilization rate of power supply.

(2) bridge-type rectifier in the utility model is hidden in former and later two plugs, not only can reduce by a lead, there is not the commutation diode structure again on the lamp string simultaneously, greatly improve the aesthetics of lamp string, and reduced the electric wire consumption to greatest extent, greatly reduced production cost.

(3) the utility model can be taken advantage of a situation the attaching plug of each bar decorative chain and supply socket to connect and is combined into different decorative chains by actual needs, and the scope of application is wide, and Practical Performance is strong.

(4) the lamp string can adopt the LED lamp of different colours in the utility model, lamp string for two or more color alignment, the user can rearrange its color combination flexibly, it designs the hommization that more becomes, thereby produce unique one's own lamp string, as adornment, because user's self participation has improved lamp string enjoyment in use greatly.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in detail:

Fig. 1 is the circuit diagram of the utility model embodiment one described improved LED decorated light string structure;

Fig. 2 is the decomposition texture schematic diagram of LED lamp in the utility model;

Fig. 3 is the assembly structure schematic diagram of LED lamp in the utility model;

Fig. 4 is the circuit diagram of the utility model embodiment two described improved LED decorated light string structures.

The specific embodiment

Embodiment one:

As shown in Figure 1, a kind of improved LED decorated light string structure described in the utility model, comprise attaching plug 1, supply socket 2, and be connected lamp string between attaching plug 1 and the supply socket 2, one group of lamp string that described lamp string is formed by connecting by some LED lamps, be provided with in the described attaching plug 1 alternating current is become galvanic full-wave rectification conversion equipment, specifically, this full-wave rectification conversion equipment comprises the wiring board that is built in attaching plug 1 and the supply socket 2, and be connected two commutation diode D on this two wiring board, two commutation diode D part bridge-type rectifiers wherein, two parts bridge-type rectifier is promptly formed complete bridge-type rectifier, to realize the effect of all-wave AC-DC in the cycle.

The maintenance and the replacing of LED lamp for convenience, as Fig. 2, shown in Figure 3, the lamp holder of described LED lamp 3 is the detachable assembly structure that split is provided with.The LED lamp 3 of fabricated construction is because its operability flexibly, and the user can replace the lamp holder that damages with standby lamp holder at any time, improve the use value of lamp string greatly, has avoided making because of the damage of a lamp holder the awkward situation that a cluster of lamps, ornamental is scrapped of putting in order; In addition, because the resistance that the lamp string uses all is built in the attaching plug (on the lamp string not strip resistance), when comparing traditional assembly structure resistance and LED lamp being welded together, the LED lamp of strip resistance damages the back if replace (non-resistance) with standby lamp holder, will cause the lamp string to wear out rapidly and burn owing to lamp resistance that string adds is not enough.

In the utility model, the shell of LED lamp adopts translucence (primary colors) PE plastics to make, use the shell of PE material luminous soft pure, more because its outstanding colour mixture effect, for seven-color LED, use PE shell can produce effect like a dream, as festival lamp luster, increase its celebrating atmosphere effectively, greatly improved the sight and the decorative effect of LED lamp string.In addition, the shell of LED lamp also can adopt to have very strong transparent PS plastics and makes, and shell is provided with the rib structure, make the illumination effect of shell be better than common material greatly, more can show glittering and translucent starlight effect, greatly improved the sight of LED lamp string, can have been liked by consumers in general.

In the utility model, the three-phase connected structure is all adopted in described ground attaching plug and supply socket, it can be built in bridge-type rectifier in attaching plug and the supply socket easily, it not only can provide direct current for the lamp string, can also save a lead, thereby improved the aesthetics of lamp string, and saved production cost.

In addition, in attaching plug 1 or supply socket 2, can also be connected with current-limiting resistance R,,, and reduce production cost of products to greatest extent therefore to large batch of providing a great convenience property of production owing to directly do not connect resistance on the LED lamp string.

Embodiment two:

Present embodiment and the foregoing description one are basic identical, and its difference is: as shown in Figure 4, described lamp string is for to be combined by the connection in series-parallel of two groups of LED lamps.

In the present embodiment, be provided with wiring board in described attaching plug 1 and supply socket 2 are also equal, and all be connected with the part bridge-type rectifier that two commutation diode D form on two wiring boards; In addition, have the LED lamp lamp holder of four line structures and two other commutation diode D1 by two between the two adjacent LED lamp strings, these two commutation diodes are the part bridge-type rectifier also, set part bridge-type rectifier constitutes the full-wave rectification conversion equipment of a complete AC-DC respectively between two groups of part bridge-type rectifiers of described attaching plug 1 and supply socket 2 and each lamp string, with realize alternating current all-wave can both be complete in the cycle become direct current, greatly improved the utilization rate of power supply.

The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or distortion are not broken away from spirit and scope of the present utility model, if these changes and distortion belong within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and distortion.
