Detailed description of the invention
Fig. 1 is the top view of the LED lamp bead of double-side provided by the invention.
Fig. 2 is A-A cross-sectional view in Fig. 1.
Specific embodiment
The present invention provides a kind of LED lamp bead of double-side, to keep the purpose of the present invention, technical solution and effect more clear
Chu defines, and the present invention is described in more detail as follows in conjunction with drawings and embodiments.It should be appreciated that tool described herein
Body embodiment only to explain the present invention, is not intended to limit the present invention.
Fig. 1 and Fig. 2 are please referred to, the present invention provides a kind of LED lamp bead of double-side.Part shown in dotted line indicates in Fig. 1
It cannot be observed directly from outside.The nouns of locality such as "upper" as described herein, "lower" are the visual angles based on Fig. 2, it is therefore intended that are convenient for
It illustrates, and does not lie in the restriction present invention.Attached drawing is only used for explaining the LED lamp bead of the LED lamp bead double-side of the double-side
Structural principle, it is not proportional to actual product.
The LED lamp bead of the double-side include first electrode 21, second electrode 22 and insulation ontology 1, ontology it is upper
Portion offers the first recess 101, and the lower part of ontology offers the second recess 102, first recess 101 and the second recess 102
It is interconnected；First electrode is located at the bottom of the first recess；The upper surface of first electrode 21 has split first LED chip
31, second electrode is located at the top of the second recess；The lower surface of second electrode 22 is provided with second LED chip 32；First
LED chip is connect with first electrode 21 and second electrode 22 respectively by gold thread (41 and 42), and the second LED chip passes through gold thread
(43 and 44) are connect with first electrode 21 and second electrode 22 respectively；Fluorescent glue 5 is filled in first recess and the second recess.On
It states the first recess and the second recess is commonly called as " bowl ", be used as reflective.The first recess known to attached drawing is up big and down small and cross section is
Circle, and the second recess is up-small and down-big and cross section is circle；First recess and the second recess.In actual use, the first electricity
Pole and second electrode are used as anode and cathode.It is equably mixed with fluorescent powder in fluorescent glue, but does not limit the tool of fluorescent powder herein
Body parameter, because the present invention does not limit actually luminous color.
As shown in Fig. 2, further, first electrode is located at the top of second electrode, non-interference, the first LED chip 31
Positioned at the middle part of 101 bottom of the first recess；Second LED chip 32 is located at the middle part at 102 top of the second recess.The setting is so that
One LED chip and the second LED chip position are placed in the middle, therefore it is more uniform to shine, and practical luminous efficiency is higher.
As shown in Figure 1, first electrode 21 includes the first vertical arm 211 and the first transverse arm 212, second electrode 22 includes second perpendicular
Arm 221 and the second transverse arm 222；222 width of first transverse arm 212 and the second transverse arm are equal." cross " described herein, " perpendicular " are only
It is only easy for illustrating, is not used in restriction invention.By the first vertical arm of setting and the second vertical arm, heat-conducting effect can be improved, it can
The heat that first LED chip and the second LED chip generate is conducted to ontology, achievees the purpose that heat dissipation, guarantees the first LED chip
With the service life of the second LED chip.First vertical arm and the second vertical arm distinguish protruding ontology for connecting external circuit.
Preferably, first electrode 21 and second electrode 22 are made of copper, and ontology 1 is made of ceramic, and are further ensured that thermally conductive
Effect.
Further, the upper surface of the fluorescent glue 5 is concordant with the upper surface of ontology 1, the lower surface of fluorescent glue 5 and ontology
1 lower surface is concordant；The upper and lower surfaces of ontology have been covered each by one layer of silica gel 6, and certainly, silica gel 6 also covers fluorescent glue 5
Lid.By covering one layer of silica gel, waterproof action is played, the service life of lamp bead is improved.
Further, the side wall of the first recess 101 and the second recess 102 is frosting, the first recess and the second recess
Side wall be respectively arranged with silver coating (11 and 12).Since frosting is arranged, so that the connection between silver coating and frosting is more
Add securely, avoids silver coating breakage, falls off.
Preferably, the roughness Ra of the side wall of the first recess 101 and the second recess 102 is 50~80 microns.
Preferably, the respectively arranged silver coating of the side wall of the first recess and the second recess (11 and 12) is mirror surface silver lustre.
Due to mirror surface silver lustre reflective function with higher, luminous efficiency is further improved.
By above-mentioned analysis it is found that compared with prior art, the first LED in the LED lamp bead of double-side provided by the invention
The light small part that chip issues can be shot down after being reflected down after the second recess, and the second LED chip issues
Light small part be reflected upward after can be projected upwards after the first recess, due to not set transparent substrate, avoid
Light is absorbed by transparent substrate.Further, since the first recess and the second recess are provided with, so that light is from upper and lower faces
It projects, avoids light from distributing from side, improve the luminous efficiency of lamp bead upper and lower surface.Further, due to the first electricity
It is shifted to install in pole and second electrode height, so that the first LED chip and the second LED chip can be centrally located, from
And the light that lamp bead upper and lower surface is issued is more uniform.
It, can according to the technique and scheme of the present invention and its hair it is understood that for those of ordinary skills
