See also Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, Fig. 2 is the schematic diagram of the embodiment one of the utility model LED conducting wire frame structure.Fig. 3 is the schematic diagram of the embodiment two of the utility model LED conducting wire frame structure.Fig. 4 is the schematic diagram of the embodiment three of the utility model LED conducting wire frame structure.Fig. 5 is the schematic perspective view of the utility model LED conducting wire frame structure through plastic shaping.
See also shown in Figure 2, the embodiment one of the utility model LED conducting wire frame structure, it is to be arranged with array way by a plurality of lead frame unit 30 to form, each lead frame unit 30 is to comprise again: a metal framework 31 and a metal base 32.
Can further have at least one first perforation, 323 and one extension 324 on first metallic plate 321, first perforation 323 is arranged on first metallic plate 321,324 of extensions are for outwards to protrude along the end of first metallic plate 321, and are arranged on the side of first conductive feet 33.First perforation 323 is all at the plastics that help the interlock ejection formation, so that plastics and LED conducting wire frame structure 20 are combined closely with the function of extension 324.Because LED conducting wire frame 20 is after the plastics injection molding, outside the extension 324 of first metallic plate 321 still can be exposed to, so the extension 324 on first metallic plate 321 can further have one second perforation 325, can help the polarity of identification light-emitting diodes pipe electrode by second perforation, 325 setting on the extension 324, so that providing of DC power supply to be provided.
Second metallic plate 322, it is to be oppositely arranged with first metallic plate 321, and and 321 of first metallic plates be formed with an opening.Second metallic plate 322 is the 3rd frames 313 that are installed in metal framework 31 by one second conductive feet 34, and second conductive feet 34 is that the 3rd frame 313 to metal framework 31 extends from the end of second metallic plate 322, and is connected with the 3rd frame 313.Also can have at least one first perforation, 323 and one extension 324 again on second metallic plate 322, first perforation 323 is arranged on second metallic plate 322,324 of extensions are for outwards to protrude along second metallic plate, 322 ends, and are arranged on the side of second conductive feet 34.First perforation 323 and extension 324 be all in order to helping the interlock plastics when LED conducting wire frame structure 20 ejection formations, in order to fixedly LED conducting wire frame structure 20 and plastics.
After LED package is finished, be to be to be connected with second conductive feet 34 with external power source by first conductive feet 33.When first conductive feet 33 was the negative electrode pin, then second conductive feet 34 was the anode pin.Same, when first conductive feet 33 was the anode pin, then second conductive feet 34 was the negative electrode pin.
See also Fig. 3, shown in Figure 4, LED conducting wire frame structure 20 can further have pair of engage members 315 or two pairs of strutting pieces 315, and is installed in second frame 312 and the 4th frame 314 of metal framework 31 respectively.When the plastics ejection formation, owing to metal base 32 and strutting piece 315 all can be coated by plastics, thus can support plastics with help by the setting of strutting piece 315, and can avoid causing LED conducting wire frame 20 distortion in the plastic shaping process.
See also shown in Figure 5ly, can form a plastic casing 50 behind the plastics injection molding, and because first metallic plate 321 and 322 of second metallic plates of metal base 32 are formed with an opening, so plastic casing 50 is formed with a perforation in the opening corresponding section.So can insert a cooling base 60 in this perforation by the below, and, can make metal base 32 reach thermoelectricity and separate with cooling base 60 by the setting of cooling base 60.
Cooling base 60 central authorities are formed with a groove, can be as the crystal bonding areas 70 of placing LED wafer, and cooling base 60 is to help the LED wafer heat radiation.In addition, plastic casing 50 is formed with several wire welding areas 80 at crystal bonding area 70 peripheries, makes first metallic plate 321 of metal base 32 and second metallic plate 322 partly expose, and provides the LED wafer behind the solid crystalline substance to carry out bonding wire.
As shown in Figure 5, in plastic casing 50 can be coated on part metals pedestal 32 and part strutting piece 315, the strutting piece 315 of both sides is in order to help to support peripheral plastic casing 50, but strutting piece 315 is not connected with metal base 32, in other words, strutting piece 315 is electrically to separate with metal base 32, so when external power supply on metal framework 31, strutting piece 315 can't form the galvanic circle with metal base 32.
When LED conducting wire frame 20 through the plastics ejection formation, again that LED wafer is solid brilliant in crystal bonding area 70 and after finishing routing, because first metallic plate 321 and 322 of second metallic plates of metal base 32 are formed with an opening, and electrically connect with metal framework 31 by first conductive feet 33 and second conductive feet 34 respectively, so can allow first metallic plate 321 or second metallic plate 322 electrically separate by thrusting one of them of first conductive feet 33 or second conductive feet 34 with metal framework 31.So that can directly on metal framework 31, connect the positive pole or the negative pole of DC power supply, and connect opposite electrode in first conductive feet 33 that is thrust or second conductive feet 34, whether normally luminous to detect light-emitting diode.
By this, but a plurality of light-emitting diodes on the batch detection LED conducting wire frame 20, and do not need each light-emitting diode is all dashed from metal framework 31, carry out independent detection again after becoming single light-emitting diode, so can reach and detect a large amount of light-emitting diodes simultaneously, and then shorten the efficient that promotes processing procedure detection time, reach the purpose that promotes the light-emitting diode production capacity.
Only the various embodiments described above are in order to the characteristics of this creation to be described, its purpose is had the knack of this operator and can be understood the content of this creation and implement according to this making, and the claim of non-limiting creation, the equivalence of finishing modified or modification so all other do not break away from the spirit that this creation discloses, and must be included in the claim of the following stated.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in the scope that does not break away from technical solutions of the utility model, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solutions of the utility model content, foundation technical spirit of the present utility model is to above any simple modification that embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
