Utility model content

To solve the above, the utility model provides a kind of new SMD lamp beads, can remain to meet string simultaneously after packaging The demand of change, required electric current, voltage during so as to change lamp bead normal work.

The technical solution adopted in the utility model is：

A kind of new SMD lamp beads, including pedestal and LED chip, the pedestal are provided with encapsulating table and located at encapsulating tables The upper conducting strip for being used to connect LED chip, the encapsulating table are provided with four conducting strips, and each conducting strip along the encapsulating table by Extend to from inside to outside encapsulating table both sides external formed conductive pin, the conducting strip with two be one group of symmetry arrangement in pedestal On, it is connected with LED chip between every group of two conducting strips, the encapsulated layer covered with packaging LED chips on the encapsulating table.

Preferably, the conducting strip is shaped as L-type or rectangle.

Preferably, the encapsulating table is provided with the locating slot matched with the conducting strip, and the conducting strip is inlayed in positioning Maintain an equal level in groove and with encapsulating table end face.

Preferably, the inside bending in the end of the conductive pin and extend along base bottom.

It is furthermore preferred that the encapsulated layer is fluorescent colloid.

It is furthermore preferred that the pedestal is macromolecule non-conducting material part.

The beneficial effects of the utility model are：SMD lamp beads of the present utility model, four conducting strips are set on pedestal, led Electric piece with two be one group of symmetry arrangement on pedestal, be connected with LED chip between every group of two conducting strips, be packaged into SMD lamps , can be by changing the connected mode realization string of conductive pin and external circuit and switching, so as to change lamp bead normal work after pearl Shi Suoxu electric current, voltage, structure are practical reliable.

Embodiment

In order that technical problem to be solved in the utility model, technical scheme and beneficial effect are more clearly understood, with Under in conjunction with the embodiments, the utility model is described in detail.Specific embodiment described herein is only explaining this practicality It is new, it is not used to limit the utility model.

Embodiment one：

As illustrated in fig. 1 and 2, the present embodiment provides a kind of new SMD lamp beads, including pedestal 1 and LED chip, the pedestal 1 It is provided with encapsulating table and is used for the conducting strip for connecting LED chip on encapsulating table, the encapsulating table is provided with four conductions Piece, and each conducting strip extends to encapsulating table both sides external along the encapsulating table and forms conductive pin, the conducting strip from inside to outside It is one group of symmetry arrangement on pedestal 1, being connected with LED chip, the encapsulating table overlying between every group of two conducting strips with two The encapsulated layer 8 of packaging LED chips is stamped, wherein, encapsulated layer 8 is fluorescent colloid, and pedestal 1 is macromolecule non-conducting material part.

The conducting strip that the embodiment uses illustrates for L-type structure by taking Fig. 2 as an example, and conducting strip is divided into the first conducting strip 2nd, the second conducting strip 3, the 3rd conducting strip 4 and the 4th conducting strip 5, the first conducting strip 2 and the second conducting strip 3 are one group, and the 3rd leads The electric conducting strip 5 of piece 4 and the 4th is another group, and the first LED chip 6 is connected between the first conducting strip 2 and the second conducting strip 3, the Two LED chips 7 are connected between the 3rd conducting strip 4 and the 4th conducting strip 5, the first conductive pin 21 of the corresponding extraction of each conducting strip, Second conductive pin 31, the 3rd conductive pin 41 and the 4th conductive pin 51, the inside bending in end of each conductive pin and along base The extension of 1 bottom of seat.

In order that conducting strip encapsulation is more firm, encapsulating table is provided with the locating slot matched with the conducting strip, the conduction Piece inlays to maintain an equal level in locating slot and with encapsulating table end face.

With reference to this example demonstrates that the utility model string and the method changed：Conducting strip is divided to two groups, every group by left and right All connect a LED chip and encapsulate, when the second conductive pin 31 is connected by external circuit with the 3rd conductive pin 41, first leads When electric pin 21 is connected positive and negative electrode respectively with the 4th conductive pin 51, two LED chips are series connection；When the first conductive pin 21 It is connected with the 3rd conductive pin 41 and connects positive pole, when the second conductive pin 31 is connected with the 4th conductive pin 51 and connects negative pole, two Individual LED chip is parallel connection.So, though internal structure has been fixed after encapsulation, the LED lamp bead product after encapsulation can be with outside Different modes that circuit is connected with conductive pin realize string and switching, required electric current during so as to change lamp bead normal work, Voltage.
