It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

Fig. 1 to fig. 3 schematically show according to the utility model discloses a SMD plush copper LED lamp pearl.

As shown in fig. 1 to 3, the utility model discloses a SMD plush LED lamp pearl includes chip 4, support 1, wire 5, support pin 2 and plush lens 6. The chip 4 comprises a red light chip 41, a green light chip 42 and a blue light chip 43, an R area, a G area and a B area are arranged in the support 1, and the support welding table 3 is respectively arranged on the R area, the G area and the B area. The red chip 41, the green chip 42 and the blue chip 43 are respectively soldered on the mount pads 3 of the R region, the G region and the B region. The raised-head lens 6 is encapsulated and formed on the support 1. Preferably, the raised-head lens 6 is encapsulated and formed by the encapsulation glue in an injection mode, so that the molding is convenient. The raised-head lens 6 can be round and matched with the shape of the bracket 1; the raised-head lens 6 may also have an elliptical shape. The support pins 2 are located on the outer side of the support 1 and connected with the chip 4 through wires 5. The utility model discloses a SMD LED lamp pearl is through gathering RGB three primary colors inside same lamp pearl, arrange each other between the different photochromic, send the light of different colours, satisfy the user to the demand of different colours, can solve the single problem of current LED lamp pearl colour, the light that RGB lamp pearl sent simultaneously can strengthen the spotlight effect through plush copper lens 6 to reduce luminous angle, improve the luminous luminance of lamp pearl, can also reach the effect of optimizing the facula.

The number of the support pins 2 is four, the four support pins 2 are symmetrically distributed on two sides of the support, and the four support pins 2 are respectively a common anode pin 21, a red light cathode pin 22, a green light cathode pin 23 and a blue light cathode pin 24. The anode and the cathode of the red light chip 41 are respectively and electrically connected with the common anode pin 21 and the red light cathode pin 22 through wires 5; the anode and cathode of the green chip 42 are electrically connected to the common anode lead 21 and the green cathode lead 23, respectively, through wires 5; the anode and cathode of the blue chip 43 are electrically connected to the common anode lead 21 and the blue cathode lead 24, respectively, through wires 5. Therefore, the cathodes of the red light chip 41, the green light chip 42 and the blue light chip 43 can be led out through different pins, the anodes are connected together, and the chips with different colors emit light with different colors after being electrified.

The material of the lead 5 may be one or more selected from gold wire, silver wire, copper wire and alloy wire.

The gold wire has the characteristic of stable performance, and is generally used for preventing oxidation and ensuring stable contact. The common single-electrode chip is of a vertical structure, the bottom can be directly electrified, so that one electrode is omitted, the electrode is directly arranged on a substrate, and the common red-yellow chip is more. The double lines are mostly in a horizontal structure, the anode and the cathode are arranged on the same plane, and the bottom substrate is insulated, so that the blue-green chip is generally used.

The copper wires comprise single crystal copper wires and palladium-plated copper wires, and are characterized by low price, the copper wires of various specifications used in lead bonding have the cost of only 1/3-1/10 of gold wires, and the copper wires have great application potential in the aspect of reducing the cost. Copper wire is relatively high in strength to gold wire, so that the copper wire is more suitable for fine wire bonding. The disadvantages are that the copper wire is easy to be oxidized, the bonding process is unstable, and the physical parameters such as hardness, yield strength and the like are higher than those of gold and aluminum.

The silver wire is characterized in that the silver wire is easy to store (the copper wire needs to be sealed, the storage period is short, the silver wire does not need to be sealed, the storage period can reach 6-12 months), but the hardness is soft, and the parameter adjustment of a machine table is not very large; the price is lower than that of gold wire and higher than that of copper wire. But is not easy to oxidize, and gas protection is not needed during routing; the pull force is not as strong as that of gold wire, but the light decay time is better than that of gold because silver does not absorb light.

Alloy wires, also known as silver alloy wires, are products that replace traditional gold wires in the LED industry. The alloy wire mainly comprises monocrystalline silver, and the content of the monocrystalline silver is 90% -99%. On the basis of gold wire, a great deal of silver is doped, and palladium and other components for keeping IMC stable are various trace elements. The welding wire has the advantages of low price, lower price than a gold wire, higher price than a copper wire and better weldability when being welded with the silver-plated bracket 1; but requires immature application on old wire bonding equipment or additional nitrogen protection. Has a certain oxidizability, which is the same disadvantage as copper wires, and protective gas is used for packaging.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
