The specific embodiment

LED lamp string of the present utility model comprises electric wire and at least one LED lamp.The lamp base of described LED lamp is electrically connected with electric wire, and is wrapped to form monolithic construction at the position that connects by the glue seal structure.Described electric wire inserts power supply, for described LED lamp provides power supply.

As shown in Figure 1, be first embodiment of LED lamp string of the present utility model, in the present embodiment, the lamp base of LED lamp 11 is connected with a current-limiting resistance 12 earlier, and then is connected to electric wire 19.Described current-limiting resistance 12 is used to protect LED lamp 11, avoids excessive electric current that LED lamp 11 is caused damage.When making, earlier electric wire 19 is connected with terminal machine with the lamp base of LED lamp 11 or with artificial spot welding, directly form glue seal structure 13 with mould then, this glue seal structure 13 gets up the connecting portion sealed envelope of LED lamp 11 pin and electric wire 19, forms an integral body.In the present embodiment, glue seal structure 13 is the beer head, by the mode that penetrates with plastic cement, can avoid problems such as product loose contact or broken string, and this glue seal structure 13 wraps in the inside with electric wire 19 and LED lamp 11 pin and resistance 12 fully, has favorable waterproof property.Understandable, resistance 12 can concentrate design on circuit board independently, and is arranged on outside the glue seal structure 13.

In the present embodiment, its work flow is: at first, be as shown in table 1 with the parameter adjustment of high-pressure injection moulding equipment;

Table 1

Temperature (℃)		Pressure (Kg/Cm ²)			The injection time (S)	Pine moves back the time (S)	Cool time (S)
Temperature (℃)		Pressure (Kg/Cm ²)						The upper limit	Lower limit	Stagnation pressure	One presses	Two press
180	175	60	31	16				The upper limit	Lower limit	Stagnation pressure	One presses	Two press	6	1	0

Then, check whether current-limiting resistance welds well; Then electric wire and current-limiting resistance are put in the groove of counterdie, covered patrix; Starting device is injected into sizing material in the mould then, forms the beer head, and then LED lamp base, current-limiting resistance, electric wire are encapsulated in the same beer head.

The another kind of way of realization of glue seal structure is for adopting the end socket of encapsulating moulding, and its moulding process flow process is: at first, electric wire welded or beat form of terminal according to production requirement with the LED lamp be connected; Then, matched mould bar is put into the baking box preheating, to prevent when encapsulating encapsulates, producing steam bubble; Then, good in succession LED lamp string sequenced put into the mould bar and begin encapsulating, used resin must be the same with the resin of packaged LED lamp holder, with unfavorable conditions such as the dead lamps of the different LED of the causing lamp of coefficient that prevents from when baking box toasts to expand because of splashing; Then, isotype the anchor clamps of lamp polyphone of having irritated glue are put into baking box together, temperature is controlled at 100-105 ℃, can not turn to be yellow to guarantee lamp holder, and stoving time got final product in about 45 minutes, after baking finishes, can form end socket, and LED lamp lamp base and electric wire are packaged together.At last, the lamp string that oven dry is got well takes out from mould bar and anchor clamps and tests.

In addition, can current-limiting resistance be arranged in the LED lamp, form the LED lamp of built-in resistor, avoided the resistance interruption of external resistance generation, the situation of short circuit, improved the stability of LED lamp string work by in described LED lamp, being packaged with the mode of current-limiting resistance.

The outer wall of described beer head 13 is provided with sucker 14, thereby LED lamp string can be absorbed and fixed on glass or the metope, as shown in Figure 2.As shown in Figure 3, hook 15 can be set on the top of beer head 13, thereby LED lamp string is hung in position.Sucker 14 and hook 15 certainly are set simultaneously, also can select the one setting.

As shown in Figure 4, described LED lamp string can link together a plurality of LED lamp 11 usefulness one wire 19 series, parallel, forms a long strip shape lamp string.The electric wire 19 of this LED lamp string can connect transformer 17, and the incoming transport power supply is for LED lamp 11 provides power supply.Certainly, also can be connected, insert dc source with battery.Can sheathed lampshade 18 in the periphery of each LED lamp 11, play decoration function.Described lampshade 18 can be made with transparent or semitransparent materials such as acrylic, resins.The moulding of described lampshade 18 can design as required, for example is designed to star-like, flower type, radial or the like.

For beer head 13 is connected with lampshade 18, be provided with thread 16 at this beer head 13 near the part of described LED lamps 11, as shown in Figure 1, and the inboard of lampshade 18 is provided with corresponding thread, screws by matching of thread.Also can salient point be set in the position of beer head 13 close described LED lamps 11, the corresponding inboard at lampshade 18 is provided with pit, thereby by the cooperate chucking of salient point with pit.

As shown in Figure 5, be second embodiment of LED lamp string of the present utility model, the difference of itself and a last embodiment is, has increased the setting of control box.Described control box comprises shell and is arranged on the interior circuit board 23 of described shell.

Described shell is made up of loam cake 21 and lower cover 22, can be combined into an integral body by modes such as screw, ultrasonic bonding.For the ease of fixing, be provided with sucker 24 at the sidewall of described shell; Hook 25 perhaps is set at the top of loam cake 21.Sucker 24 and hook 25 certainly are set simultaneously, also can select one and select to be provided with.

Described circuit board 23 is fixedly mounted in the described shell, is connected with transformer 26 and inserts power supply.And described circuit board 23 is provided with the control circuit and the current-limiting resistance of the described LED lamp 28 of control.Insert described shell with LED lamp 28 wire connecting 27, be connected with described circuit board 23.By control circuit and current-limiting resistance, can control LED lamp 28 and glimmer, light by certain rule etc.Wherein, the link position place of the lamp base of LED lamp 28 and electric wire 27 can be tightly connected by the beer head equally; And electric wire 27 can adopt beer head ways of connecting to be connected and sealed with being connected of circuit board 23 equally, improves waterproof effect.

As shown in Figure 6, be the 3rd embodiment of LED lamp string of the present utility model, the difference of itself and first embodiment is that this LED lamp string is provided with the remote control receiving box of control LED lamp 31 work; And LED lamp 31 is a plurality of, and each LED lamp 31 is connected to the remote control receiving box by a wire 32 respectively.In the present embodiment, described LED lamp 31 is " rice " font and distributes, and certainly according to actual needs, is designed to different shape.

Described remote control receiving box comprises shell and is arranged on the interior circuit board 33 of described shell.Described shell is combined into an integral body by loam cake 34 and lower cover 35 by modes such as screw, ultrasonic bonding.For the ease of fixing, be provided with sucker at the sidewall of described shell; Messenger wire 37 and messenger wire grab 38 perhaps are set at the top of loam cake 34.Sucker and messenger wire grab 38 certainly are set simultaneously, also can select one and select to be provided with.
