Background technology:

LED, light-emitting diode is a kind of can be the solid-state semiconductor device of visible ray by electric energy conversion, and it directly can be converted into light electricity.The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a support, and one end is negative pole, and the other end connects the positive pole of power supply, makes whole wafer by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is P type semiconductor, and inside it, occupy an leading position in hole, and the other end is N type semiconductor, at this side mainly electronics.But time these two kinds of semiconductors couple together, between them, just form a P-N junction.When electric current acts on this wafer by wire time, electronics will be pushed to P district, and in P district, electronics is with hole-recombination, then will send energy with the form of photon, the principle of LED luminescence that Here it is.And the wavelength of light i.e. the color of light, be determined by the material forming P-N junction.

LED light source because of have use low-tension supply, power consumption less, applicability is strong, stability is high, the response time is short, environmentally safe, the advantage such as multicolor luminous, become main flow lighting source of new generation, LED instead of existing incandescent lamp, fluorescent lamp etc. gradually as the LED lamp tube, LEDbulb lamp etc. of lighting source, along with high efficiency, the LED market demand of low cost, the trend of the integration packaging LED become gradually, how encapsulation factory is switched to integration packaging by the small-power packing forms of routine fast just seems particularly important.

China Patent No. " 201220646714.6 " discloses a kind of multifunctional unit LED support, and its advantage is: the multiple wafer of accessible site in die bond portion, can realize integration packaging; Die bond portion area design is enough large, for better heat radiation, realizes better radiating effect; Wafer can also adopt RGB integrated wafer, is directly welded in crystal bonding area, makes all-colour LED.Its weak point is: the light that LED wafer sends there will be mixed light problem, affects rgb color effect; Its die bond portion package cavity size can not adjust, and can not hold large-sized LED wafer, have limitation to LED luminescence.

Utility model content:

In order to solve the problem, it is simple that the utility model provides a kind of structural principle, solving the mixed light problem of RGB, can also regulate the size of package cavity simultaneously, be convenient to encapsulate large-sized LED wafer, strengthens the technical scheme of the illumination effect of LED:

A kind of multifunctional unit LED lamp holder, mainly comprise insulating support main body and be connected to insulating support main body and outward extending six conductive pins, the connection all of six conductive pins has multiple die bond portion for placing LED wafer, die bond portion is provided with package cavity, bottom is provided with plastic cement seat, six conductive pin produced by insert molding are in plastic cement seat, plastic cement seat is provided with weld part, weld part comprises the first bending part and the second bending part, the wrap direction of the first bending part is contrary with the opening direction of package cavity, second bending part is coated on outside plastic cement seat to side bending, and this second bending part extending laterally out from the first bending part, the wrap direction of the second bending part is vertical with the wrap direction of the first bending part, die bond portion arranges three, be respectively the first die bond portion, second die bond portion, 3rd die bond portion, first die bond portion, second die bond portion, 3rd die bond portion is located on the same line.

As preferably, six conductive pins of setting are respectively the first conductive pin, the second conductive pin, the 3rd conductive pin, the 4th conductive pin, the 5th conductive pin, the 6th conductive pin.

The beneficial effects of the utility model are:

(1) the utility model improves on basis before, and arranged point-blank in multiple die bond portion, the light that LED wafer is sent there will not be the skew of light source in visual effect, can not produce mixed light problem.

(2) the utility model improves on basis before, on the plastic cement seat adopted, the wrap direction of weld part is contrary with the opening direction of package cavity, reach the object of the size regulating package cavity, be convenient to encapsulate large-sized LED wafer, strengthen the illumination effect of LED.

Fig. 2 is die bond portion of the present utility model front view.

Embodiment:

For making goal of the invention of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, execution mode of the present utility model is described in further detail.

As shown in Figure 1 and Figure 2, a kind of multifunctional unit LED lamp holder, mainly comprise insulating support main body 1 and be connected to insulating support main body 1 and outward extending six conductive pins, the connecting portion of six conductive pins has multiple die bond portion 2 for placing LED wafer, die bond portion 2 is three, is respectively the first die bond portion 22 of die bond portion 21, second, the 3rd die bond portion 23.Die bond portion 2 is provided with package cavity 3, and bottom is provided with plastic cement seat 4, six conductive pin produced by insert molding in plastic cement seat 4.

Six conductive pins arranged are respectively the first conductive pin 11, second conductive pin 12, the 3rd conductive pin 13, the 4th conductive pin 14, the 5th conductive pin 15, the 6th conductive pin 16.First conductive pin 11, the 6th conductive pin 16 connect the first bottom, die bond portion 21 respectively; Second conductive pin 12, the 5th conductive pin 15 connect the second bottom, die bond portion 22 respectively; 3rd conductive pin 13, the 4th conductive pin 14 connect the 3rd bottom, die bond portion 23 respectively.

In the present embodiment, existing basis is improved, the first die bond portion 22 of die bond portion 21, second, the 3rd die bond portion 23 are arranged on same straight line.After LED wafer correspondence is installed in the die bond portion 2 on the connecting portion of six conductive pins, because these die bond portions are located on the same line, then LED wafer also will be located on the same line, its light sent there will not be the skew of light source, also can not produce mixed light problem, effectively can keep the consistency of whole RGB in visual effect.、
