Abstract
The utility model relates to application technology of light emitting diode (LED) semiconductor luminescent devices, in particular to a plastic packaged LED string light. A plurality of LED modules are connected in series through a power supply outgoing wire to constitute the plastic packaged LED string light. The LED modules comprise printed circuit boards and protuberant LED lamps, and the LED lamps are welded on the printed circuit boards. The plastic packaged LED string light is characterized in that the front face of each printed circuit board surrounding each LED lamp is connected with a layer of protuberant poly carbonate (PC) material protective layer by infection molding, a gap ring between each LED lamp and the PC material protective layer is hermetically covered with a layer of transparent solidified glue, and the back face of each printed circuit board is connected with a layer of PC material protective layer by infection molding. The design aims at providing the plastic packaged LED string light which has good heat dissipation and can be used outdoors. Compared with the prior art, the plastic packaged LED string light has the advantages of simple production process, high production efficiency, and the like.
Description
Technical field
The utility model relates to LED light emitting semiconductor device application technology, particularly a kind of plastic packaging LED lamp string.
Background technology
The making of domestic and international similar LED lamp string module at present, the pcb board (printed circuit board (PCB)) that most technologies will be equipped with led light source is embedded in the preformed housing, adopts some glue mode to cover the PCB zone then.The LED module of this method processing must pass through a glue, technologies such as baking, and production efficiency is low; And this process structure weak heat-dissipating also should not be exposed to rainwater for a long time, under sunshine, influence out of doors and use.
Summary of the invention
The purpose of the utility model is that a kind of good heat dissipation of design can be used plastic packaging LED lamp string handsome in appearance again out of doors.
In order to achieve the above object; The utility model is taked following technical solution: a kind of plastic packaging LED lamp string; It is made up of through the power outlet serial connection a plurality of LED modules; Said LED module comprise printed circuit board (PCB) and the weldering high above that the LED lamp; It is characterized in that injection moulding connects the PC material protection layer that a floor height rises on around the front of the printed circuit board (PCB) around the said LED lamp, sealing covers layer of transparent and solidifies glue, injection moulding connection one deck PC material protection layer on the said printed circuit board (PCB) back side in the slit circle between said LED lamp and said PC material protection layer.
The good effect that the utility model compared with prior art has is: because the LED light fixture has little power consumption, the life-span is long, characteristics such as brightness height, and the LED illumination module is replacing incandescent lamp, neon light and fluorescent lamp gradually.In addition, LED lamp string module has flexible good, but characteristics such as color programme-control have the irreplaceable function of power saving fluorescent lamps.LED lamp string module is widely used in indoor outer advertising lamp box, Landscape Lighting field at present.The society that is embodied as of the utility model provides technology simple, and production efficiency is high, and good heat dissipation can be used again out of doors, for condition has been created in the extensive application of LED lamp string module.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1; Present embodiment is made up of through power outlet 2 serial connections a plurality of LED modules 1; As shown in Figure 4; Said LED module comprise high above that of aluminum-base printing circuit board 8 and weldering LED lamp 3, like Fig. 2, shown in Figure 3, injection moulding connects the PC material protection layer 4 that a floor height rises on around the front of the aluminum-base printing circuit board around the said LED lamp 3; Sealing is covered with layer of transparent and solidifies glue 5 in the circle of slit between said LED lamp 3 and said PC material protection layer 4, and injection moulding connects one deck PC material protection layer 7 on the said aluminum-base printing circuit board back side.
The manufacture craft flow process of present embodiment plastic packaging LED lamp string is following:
1, by conventional fabrication processes, make the naked lamp of LED module, as required the naked lamp serial connection of a plurality of LED modules is constituted LED module lamp string, as to be formed;
2, get to be formed LED module lamp string, the LED lamp on the printed circuit board (PCB) of the naked lamp of LED module is faced up, keep flat in the die of mould; There is the protrusion periphery at the punch center on the die of covering, with the LED lamp around, isolate with the injection moulding periphery; By the PC material to peripheral integral molded plastic moulding.The cooling back demoulding is at each self-forming one deck PC material protection layer 4,7 of printed circuit board (PCB) front and back.
3, seal covering in the slit circle of employing transparent glue between said LED lamp 3 and said PC material protection layer 4, form layer of transparent and solidify glue 5, after receipts were done, plastic packaging LED module lamp string completed.
Claims (1)
1. plastic packaging LED lamp string; It is made up of through power outlet (2) serial connection a plurality of LED modules (1); Said LED module (1) comprise printed circuit board (PCB) (8) and the weldering high above that LED lamp (3); It is characterized in that injection moulding connects the PC material protection layer (4) that a floor height rises on around the front of said LED lamp (3) printed circuit board (PCB) (8) on every side; Sealing covering layer of transparent is solidified glue (5) in the slit circle between said LED lamp (3) and said PC material layer (4), goes up injection moulding at the said printed circuit board (PCB) back side (6) and connects one deck PC material protection layer (7).
