Abstract
The utility model discloses an SMT (Surface Mount Technology) LED light bar which adopts a sunken pad, namely the surface of a printed circuit board is drilled with blind holes in which the pad is positioned and SMT LEDs are mounted, so that the thickness of a whole light bar is the same as that of the printed circuit board and is reduced compared with that of the existing light bar; the LEDs are positioned in the blind holes of the printed circuit board and can not be higher than the surface of the printed circuit board, so that the distance between the SMT LED and the surface of the shell is increased after the light bar is arranged inside the shell, the effect after the light overlaps can be improved, and the phenomenon of point light sources can be effectively reduced; and as the SMT LEDs are embedded into the printed circuit board, the phenomena such as collision, friction, extrusion, loosing of the SMT LEDs or damage of the internal structures thereof during transportation can be avoided completely.
Description
Technical field
The utility model relates to a kind of LED lamp bar, specifically relates to a kind of lamp bar that face of weld mounts LED that is used for.
Background technology
Existing surface mount LED (SMD LED) lamp bar generally is the printed circuit board (PCB) that a block welding has some surface mount LED, its structure and manufacturing process are as follows: have some pads that face of weld mounts LED that are used on the surface of printed circuit board (PCB), on pad, brush tin cream, then surface mount LED direction according to the rules is attached on the tin cream of having brushed, the printed circuit board (PCB) that will post surface mount LED then is placed in the Reflow Soldering machine and heats, make the tin cream fusing, again printed circuit board (PCB) is slowly cooled off tin is solidified, thereby realize LED is welded on the printed circuit board surface, as shown in Figure 1.Above-mentioned lamp bar has following defective: as shown in Figure 1, because surface mount LED2 is welded in the surface of printed circuit board (PCB) 1, make that the integral thickness of lamp bar is too thick; As shown in Figure 2, after lamp strip unit is gone into shell 4, because the distance of surface mount LED2 and upper surface of outer cover is too near, make the mixed poor effect of light, and spot light is obvious; And for example shown in Figure 1, because surface mount LED is mounted on the surface of printed circuit board (PCB), in collision, friction, extruding or transportation, can cause the loosening or internal structure disrepair phenomenon of surface mount LED.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of surface mount LED lamp bar, this surface mount LED lamp bar reduced integral thickness, the mixed light of lamp bar effective, effectively alleviate the spot light phenomenon, and the loosening or internal structure disrepair phenomenon of surface mount LED that can avoid colliding, rub, cause in extruding or the transportation.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of surface mount LED lamp bar, have some pads that face of weld mounts LED that are used on the printed circuit board (PCB), printed circuit board surface offers some blind holes, described some blind holes are corresponding one by one with some pads, described pad sinks in its corresponding blind hole, surface mount LED electrically is fixedly connected on the pad in the blind hole, and surface mount LED is arranged in blind hole and does not exceed printed circuit board surface.
The beneficial effects of the utility model are: because the pad of surface mount LED lamp strip adoption depressed, it is the printed circuit board surface drilling blind hole, pad is arranged in blind hole, surface mount LED is mounted in the blind hole, make that the thickness of lamp bar integral body is identical with the thickness of printed circuit board (PCB) plate, reduced thickness than existing lamp bar; Because surface mount LED is arranged in the blind hole on the printed circuit board (PCB) and do not exceed printed circuit board surface, make that lamp strip unit is gone into shell after, surface mount LED and case surface be apart from increasing, the effect after helping light overlapping can effectively alleviate the spot light phenomenon; Because surface mount LED is embedded in the printed circuit board (PCB), the loosening or internal structure disrepair phenomenon of surface mount LED that can avoid fully colliding, rub, cause in extruding or the transportation.
Description of drawings
Fig. 1 is existing surface mount LED lamp bar structural representation;
Fig. 2 is the light excessive effects figure after existing surface mount LED lamp strip unit is gone into shell;
Fig. 3 offers the printed circuit board (PCB) schematic diagram of blind hole for the utility model;
Fig. 4 is the utility model structural representation;
Fig. 5 is the light excessive effects figure after surface mount LED lamp strip unit of the present utility model is gone into shell.
The specific embodiment
Embodiment: a kind of surface mount LED lamp bar, have some pads that face of weld mounts LED that are used on the printed circuit board (PCB), printed circuit board surface offers some blind holes, described some blind holes are corresponding one by one with some pads, described pad sinks in its corresponding blind hole, surface mount LED electrically is fixedly connected on the pad in the blind hole, and surface mount LED is arranged in blind hole and does not exceed printed circuit board surface.
As shown in Figure 3, because the pad of surface mount LED lamp strip adoption depressed, it is printed circuit board (PCB) 1 surperficial drilling blind hole 3, pad is arranged in blind hole, as shown in Figure 4, surface mount LED2 is mounted in the blind hole, makes that the thickness of lamp bar integral body is identical with the thickness of printed circuit board (PCB) plate, has reduced thickness than existing lamp bar; As shown in Figure 5, because surface mount LED2 is arranged in the blind hole on the printed circuit board (PCB) 1 and do not exceed printed circuit board surface, make that lamp strip unit is gone into shell 4 after, surface mount LED and case surface are apart from increasing, effect after helping light overlapping can effectively alleviate the spot light phenomenon; Because surface mount LED is embedded in the printed circuit board (PCB), the loosening or internal structure disrepair phenomenon of surface mount LED that can avoid fully colliding, rub, cause in extruding or the transportation.
