A kind of New LED dewdrop lamp
Technical field
The utility model relates to decoration or lighting field, particularly relates to the New LED dewdrop lamp that a kind of structure is simply firm, cost is low, production efficiency is high, illumination effect is good, easy to use.
Background technology
Traditional LED dewdrop modulated structure is: be coated with on the enamel covered wire of insulating lacquer layer at two, remove insulated paint at interval of the position of certain distance being carried out polishing and expose platform-like brazing point, LED chip is fixed on platform-like brazing point, superfine wire electrode is stamped to be electrically connected LED chip and brazing point, then at the coated layer of transparent insulating cement in periphery of LED chip, wire electrode and brazing point again in LED chip He on brazing point.
The advantage that the LED dewdrop light fixture of said structure has lamp body tiny, is adapted to wrap over the enterprising luggage decorations of various modeling lamp.But the LED dewdrop lamp production requirement of this kind of structure is very meticulous, and cannot accomplish that rapid batch is produced, thus cause that yield is low, cost is high.
Its main object of LED dewdrop lamp is used to alternative traditional LED string, and namely with the LED string that a wired in series plural number vertical LED is made, traditional its production process of LED string is tired many, and volume is larger; The main purposes of LED string is for dressing a Christmas tree, lamp body because of LED string is heavier and relatively thick, thus by LED string stitch to Christmas tree time, need to bind a lot of band (being also bundling article or cable strap) between the branch of LED string and Christmas tree, use very inconvenient.
As from the foregoing, traditional LED concatenate produce and use very inconvenient, and existing LED dewdrop lamp exist cost high and cannot rapid batch produce problem, thus also cannot substitute traditional LED string fast.
In sum, be necessary to do further Improvement and perfection to existing LED dewdrop lamp.

Further, be mixed with spread powder and/or toner in described colloid and/or guide-lighting cell-shell, being mixed with spread powder can spread the light of LED better, reaches the effect of extensive angle, uniformly light-emitting; Be mixed with toner, can accomplish the effect of various glow color under the prerequisite not changing LED color, if LED is white light entirely, the colloid that diverse location LED is corresponding and/or guide-lighting cell-shell are mixed with the toner of different colours, homochromy LED can be realized and send out effect not only, convenient for production.
Further, described FPC is corrosivity printing FPC or non-corrosive FPC.
Further, described non-aggressive flexible circuitry plate structure is: two flat conductor upper and lower surfaces of being rolled by round metal silk are fitted with upper film and lower film respectively, wherein goes up film and has pad mouth in the position of welding LED.Adopt this structure, because round metal silk can be linked to be a volume, thus also can do very long with the flat conductor of wire calendering, the non-aggressive FPC adopting this flat conductor to make also can do very, and unlike traditional corrosivity printed wire because 0.5 meter long can only be accomplished by technology and equipment restriction, soldered with the corrosivity printed substrate of these 0.5 meter long, one, operation bother, its two, can not ensure connect after flexible circuitry in alignment.
Because adopting the FPC of strip as the welding supporting body of LED, FPC itself is not only elongated but also soft and lightweight, can directly be wrapped on the branch of Christmas tree, easy to use, does not need band stitch.Relative to traditional LED lamp string, lot of materials can be saved; Relative to traditional LED dewdrop lamp, can produce by rapid batch.
It is pointed out that and implement arbitrary product of the present utility model non-required to reach above institute effective simultaneously.

Detailed description of the invention
Referring to figs. 1 through the utility model preferred embodiment one shown in Fig. 5, a kind of New LED dewdrop lamp, comprise plural LEDs 1 and strip FPC 2, described plural LEDs 1 is spaced from each other and is welded on FPC 2, and described every LEDs 1 overlaps all respectively guide-lighting cell-shell 3.The light that can send LED1 carries out leaded light and diffusion, to improve the lighting angle of LED1.
Described guide-lighting cell-shell 3 inside is hollow, for covering LED1.
Described LED1 is adopting surface mounted LED, and specification adopts 3528 adopting surface mounted LEDs, and the height H of described guide-lighting cell-shell 3 is more than the twice of adopting surface mounted LED height h or twice, in the present embodiment, and the preferred 6.5mm of guide-lighting cell-shell height.
With reference to shown in Fig. 3 and Fig. 5, described guide-lighting cell-shell 3 is in semielliptical shape, described LED1 is cube shaped adopting surface mounted LED, the inner diameter that guide-lighting cell-shell 3 corresponds to the LED1 top side location position of V point (namely in Fig. 5) is slightly less than the cornerwise length of LED1 end face, the drift angle of a part for guide-lighting cell-shell 3 inwall and the LED1 end face position of V point (namely in Fig. 5) is made mutually to push up press contacts, thus realize guide-lighting cell-shell 3 and be sticked on the drift angle position of V point (namely in Fig. 5) of LED1 end face, realize that guide-lighting cell-shell 3 is physical to be fixed on adopting surface mounted LED 1; Adopt adopting surface mounted LED 1, can realize adopting surface mounting technology utilize paster machine to paste LED fast and carry out Reflow Soldering, rapid batch can be realized and produce.
Colloid 4 is filled with in the inner space that described guide-lighting cell-shell 3 and LED1 and FPC 2 surround, colloid 4 can be epoxy resin or silica gel, colloid 4 can carry out astigmatism to the light that LED sends better, simultaneously, colloid also can make guide-lighting cell-shell 3 be bonded on LED1 and FPC 2 more firmly, and colloid 4 can also cover LED1 solder joint, reach better insulation effect.
Be slightly less than the width of FPC bottom described guide-lighting cell-shell 3 along the length W of FPC 2 width, the bottom of guide-lighting cell-shell 3 can be covered by LED1 and FPC 2, thus above-mentioned colloid 4 is not easily overflowed bottom guide-lighting cell-shell.
Be mixed with spread powder in described colloid 4, can certainly be mixed with spread powder in guide-lighting cell-shell 3, being mixed with spread powder in colloid 4 can spread the light of LED1 better, reaches the effect of extensive angle, uniformly light-emitting;
Toner can also be mixed with in described colloid 4 and/or guide-lighting cell-shell 3, the effect of various glow color can be accomplished under the prerequisite not changing LED1 color, if LED1 is white light entirely, the colloid 4 that diverse location LED1 is corresponding and/or guide-lighting cell-shell 3 are mixed with the toner of different colours, homochromy LED1 can be realized and send out effect not only, convenient for production.
Described FPC 2 is non-corrosive FPC, can certainly be corrosivity printing FPC.
Described non-aggressive FPC 2 structure is: two flat conductor 5 upper and lower surfaces of being rolled by round metal silk are fitted with upper film 6 and lower film 7 respectively, wherein goes up film 6 and has pad mouth 8 in the position of welding LED1.Adopt this structure, because round metal silk can be linked to be a volume, thus also can do very long with the flat conductor 5 of wire calendering, the non-aggressive FPC 2 adopting this flat conductor 5 to make also can do very, and unlike traditional corrosivity printed wire because 0.5 meter long can only be accomplished by technology and equipment restriction, soldered with the corrosivity printed substrate of these 0.5 meter long, one, operation bother, its two, can not ensure connect after flexible circuitry in alignment.
The above, just preferred embodiment of the present utility model, the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with equal means, all should belong to protection domain of the present utility model.
