Abstract
Disclosed is an LED bead composed of an SMT (surface mount technology) base and batwing light spot lens. The LED bead is composed of a batwing light spot lens body, an LED chip, an SMT base body and a bonding pad. The batwing light spot lens body is arranged above the chip and is fixed above the SMT base, the LED chip is installed above the SMT base, and the bonding pad is arranged under the SMT base. The LED bead is mainly used in the field of LED bead packaging, and the LED bead is mainly installed on lamps of an LED street lamp and an LED tunnel lamp.
Description
Technical field
The present invention relates to LED lamp pearl, especially the LED lamp pearl of SMT pedestal and batswing tab hot spot lens composition.
Background technology
What Chinese patent notification number: CN201751679U told about is in cylindrical base, to place LED chip, bimodal lens (being batswing tab hot spot lens), two leg electrodes of support shape.This structure has following drawback:
1, two leg electrodes be generally flatiron manual welding on PCB, because being first welds a pin, then weld another pin, there will be two legs to be uneven; Or at lamp pearl work adstante febre, two leg stress are changed.These all can cause cylindrical base and PCB there is no plane close contact, and lamp pearl radiating effect is bad.
2, two leg electrodes be generally flatiron manual welding on PCB, being not suitable with SMT paster, to be welded in batches PCB upper, manual welding is time-consuming, and solder joint is large, waste scolding tin.Even if want paster welding, because two leg supports are easily out of shape when punch process and tool encapsulation or the packaging, with cylindrical base not in one plane, cause the phenomenon appearance such as weldering not go up, rosin joint, welding point defect rate is high.
3, two leg electrode sizes are excessive, increase PCB area; Cylindrical base, leg support volume are excessive, preponderance, and these all can produce waste of material.
Summary of the invention
The present invention installs LED chip and batswing tab hot spot lens on SMT paster pedestal, and SMT paster pedestal contacts with PCB closely, lamp pearl good heat dissipation effect; Pad below SMT paster pedestal is smooth little with the variation of PCB welding stress, and reliability is high, welding point defect rate is low, and scolding tin consumption is few; SMT paster base size is lightweight, saves material.(LED lamp pearl volume-diminished 40% ~ 60%, weight saving 60% ~ 80%).
The present invention is mainly made up of batswing tab hot spot lens, LED chip, SMT paster pedestal, pad, and batswing tab hot spot lens are arranged on above SMT paster pedestal, and both combine becomes external overall.LED chip is installed in the middle of above SMT paster pedestal, and batswing tab hot spot lens cover is on LED chip.Below SMT paster pedestal, pad is set.
The present invention is mainly used in LED lamp pearl encapsulation field, and lamp pearl is mainly arranged on the light fixture of LED street lamp, LED Tunnel Lamp.
The invention has the beneficial effects as follows: only because making existing cylindrical bimodal lens LED lamp pearl into LED lamp pearl that SMT paster pedestal combines with batswing tab hot spot lens, LED lamp pearl of the present invention and PCB welding are easily, contact tight good heat dissipation, adapt to batch jobs, the low reliability of welding point defect rate is high, saves material.
brief description of the drawings:

Fig. 2 is top view of the present invention;
Fig. 3 is cutaway view of the present invention.
Sequence number explanation in figure: 1, batswing tab hot spot lens, 2, LED chip, 3, SMT paster pedestal, 4, pad.
Detailed description of the invention
On SMT paster pedestal 3, LED chip 2 is installed, batswing tab hot spot lens 1 be placed in the top of LED chip 2 and be fixed on SMT paster pedestal 3 above, SMT paster pedestal 3 arranges pad 4 below.
