Description
Technical field
The utility model relates to LED sealing technique, relates to a kind of LED encapsulation structure that effectively can improve moisture protection specifically.
Background technology
Owing to there is space between the conventional P PA support 13 of conventional lights son and the young five metals portion 11 of conventional lights, as Fig. 5, shown in 7, moisture will enter bowl cup inside by this space 14 and cause colloid to peel off, and then break bonding wire, lamp son is finally caused to lose efficacy, because the bending of the support five metals part of the SMD LED of conventional package is too simple, for " 7 " font 12, as shown in Figure 1 and 2, moisture is more inner than being easier to enter the young bowl cup of lamp by the space 14 in the young five metals portion 11 of conventional P PA support 13 and conventional lights, thus reduce the reliability of lamp son, increase the probability that lamp son was lost efficacy.When making the lamp that outdoor LED display screen uses and being young, inner in order to prevent moisture from entering the young bowl cup of lamp by the space 14 in the young five metals portion 11 of conventional P PA support 13 and conventional lights, lamp son is caused to lose efficacy, now commonplace way is the height adding headlight son, deepen the thickness of encapsulating, extend the path that moisture enters the young bowl cup inside of lamp.
Traditional height adding headlight son, deepen the thickness of encapsulating to extend the way that moisture enters lamp son bowl cup inside by the space 14 in the young five metals portion 11 of conventional P PA support 13 and conventional lights whole display screen can be caused thicker, heavier, can give to install and use and bring very large inconvenience, also greatly can increase the cost of lamp son and display screen simultaneously.
Utility model content
The technical problems to be solved in the utility model there are provided a kind of LED encapsulation structure that effectively can improve moisture protection, and this encapsulating structure does not increase LED display thickness, weight and cost to realize extending the while that moisture entering lamp son path as far as possible.
For solving the problems of the technologies described above, the utility model is realized by following scheme:
Effectively can improve a LED encapsulation structure for moisture protection, comprise the young five metals portion of lamp, PPA support, the young five metals portion of described lamp is provided with PIN, and the first corner of the described PIN left and right sides is converted into zigzag.
Further, described PIN is converted into zigzag part and is coated in PPA support.
Further, described PPA support is provided with the Z-shaped groove matched with the zigzag in PIN.
Further, the structure in the zigzag portion that described PIN is converted into is that the upper inferior transverse part of zigzag is parallel, and middle vertical part is vertical with transverse part, and two corners of zigzag are circular arc.
Relative to prior art, the beneficial effects of the utility model are:
1. common surface-mount type light-emitting diode is structurally improved by the utility model, can better prevent entering of moisture, to be applicable to worse service condition.
2. in lamp young five metals part, PIN part is arranged to " Z " font, prolongation moisture enters the path in bowl cup.
3. substantially prolongs moisture enters bowl cup path from the space between PPA and PIN, the moisture access path of the utility model lamp son is young relative to traditional lamp suitable time expand.
4. when doing outdoor LED display screen, use the same encapsulating degree of depth, the utility model lamp son has the protection of deeper PIN, again extends the path that moisture enters the young bowl cup inside of lamp.

Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is explained in detail.
Please refer to accompanying drawing 3 ~ 4 and accompanying drawing 6 and accompanying drawing 8, a kind of LED encapsulation structure that effectively can improve moisture protection of the present utility model, comprise the young five metals portion 21 of lamp, PPA support 23, the young five metals portion 21 of described lamp is provided with PIN 22, first corner of described PIN 22 left and right sides is converted into zigzag 24, the structure of the zigzag that described PIN 22 is converted into 24 is that the upper inferior transverse part of zigzag is parallel, and middle vertical part is vertical with transverse part, and two corners of zigzag are circular arc.Described zigzag 24 part is coated in PPA support 23, and on PPA support 23, be provided with the Z-shaped groove matched with the zigzag 24 in PIN 22.
Please refer to accompanying drawing 1 ~ 2, the PIN left and right sides in the young five metals portion 11 of traditional conventional lights is " 7 " font 12 bending-likes, and the PIN left and right sides in the young five metals portion 21 of lamp of the present utility model is zigzag 24 bending-like (please refer to accompanying drawing 3 ~ 4).
Please refer to accompanying drawing 7 ~ 8, accompanying drawing 7 is encapsulating degree of depth schematic diagram after conventional P PA support coordinates with the young five metals portion of conventional lights, and H1 is the encapsulating degree of depth of conventional lights son in the drawings.Accompanying drawing 8 is encapsulating degree of depth schematic diagram after the utility model PPA support coordinates with the young five metals portion of the utility model lamp; H2 is the encapsulating degree of depth of the present utility model in the drawings; H1 > H2 can be found out from accompanying drawing; and due to the young five metals portion 21 of lamp be zigzag with the junction of PPA support 23; change the access path of moisture; therefore; adopt LED encapsulation structure of the present utility model; same effect can be issued in the situation not increasing any cost relative to traditional approach; with less encapsulating, reach same PIN protection level.
The foregoing is only preferred implementation of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
