Description
Technical field
The utility model relates to the LED paster technique, relates in particular to a kind of clamping thin slice LED paster structure and pasting method thereof, paster when can be applicable to a plurality of LED lamp pearl.
Background technology
Because light-emitting diode is a kind of high efficiency cold light light-emitting component that converts electrical energy into luminous energy, and have advantages such as power consumption is low, the life-span is long, so light-emitting diode is used for electronic product indication purposes mostly.But how light-emitting diode is used for commerce and domestic lighting or decorates still have very big space requirement to fill up.
The novel patent I229948 in Taiwan has disclosed a kind of crystal-coated light-emitting diodes array of packages and encapsulation unit thereof, mainly discloses a light-emitting diode chip for backlight unit and is arranged on the ceramic substrate, and connect the metal connecting line layer on this ceramic substrate; This porcelain substrate is to utilize heat-conducting glue to attach in the depression with a metal body.Under this way; Because this light-emitting diode chip for backlight unit and metal connecting line layer; And it is also two-layer between this metal body across this ceramic substrate and this heat-conducting glue etc.; Therefore, the heat on this light-emitting diode chip for backlight unit and the metal connecting line layer can't be transmitted to soon on this metal body and dispel the heat.Thereby relevant heat radiation way partly in this case, still have again in addition improved space, to meet the high-capacity LED product to the qualitative high request that dispels the heat.
Current; Also there is more and more researchers just being devoted to utilize the assist field intensity that adds of surface activation process and fusion to carry out the LED sealing-in; But they all need heat on entire device or substrate; This can cause unnecessary stress and temperature field to distribute, and above-mentioned sealing technology also is not easy to realize the selectivity bonding, and bonding area and heat affected area are difficult to control.Single traditional paster automaticity still has bigger room for promotion simultaneously, and the light extraction efficiency that on the basis that solves heat dissipation problem, how significantly to improve LED is also very important.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides a kind of clamping thin slice LED paster structure, and it has fabulous heat-sinking capability and light extraction efficiency; The utility model proposes a kind of pasting method of this LED paster structure simultaneously, its can be simultaneously paster to a plurality of LED lamp pearl the time, adapt to automatic batch production.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of clamping thin slice LED paster structure comprises LED lamp pearl and two clamping metals, and wherein two clamping metals are designated as anodal clamping metal and negative pole clamping metal respectively; The two ends of said LED lamp pearl are grasped by anodal clamping metal and negative pole clamping metal respectively, form wall scroll clamping LED assembly.
The LED paster structure of said structure improves its light extraction efficiency if adopt plurality of LEDs lamp pearl greatly to hang down; Simultaneously, it has the characteristic of two-sided bright dipping, has effectively improved the utilance of light source; The LED paster structure of comparing traditional, between LED lamp pearl and substrate, not across insulating barrier/glue, heat-conducting glue or gap, the heat on LED lamp pearl and the conductor layer can be dispelled the heat soon fully, and its heat dispersion is greatly improved; And because the material behavior of metal itself makes the LED paster structure of this structure have certain flexibility and mechanical strength.
The base material of said clamping metal is a foil material, can be Copper Foil, aluminium foil, iron plate or alloy sheet etc.
In order to realize welding required circuit and pad, can do turmeric in the clamping metal surface and handle.
The zone that is used to grasp LED lamp pearl on the said clamping metal is designated as the LED land, and on the relative two sides of clamping metal, preferably, designing one of them side is shiny surface, and the LED land of another side is a groove; This groove has a location and spacing effect to LED lamp pearl; Preferably, its width is slightly less than the width of LED lamp pearl, like this when LED lamp integument when compressing into corresponding grooves, groove has an engaging dynamics to it, improves the reliability of whole paster structure; Need explanation, the degree of depth of groove can not be higher than the thickness of LED lamp pearl, otherwise effective paster LED lamp pearl not only makes the effect of clamping metal lose simultaneously.
Said wall scroll clamping LED assembly is more than one, and the anodal clamping metal of each wall scroll clamping LED assembly is communicated with through cathode conductor layer, and the negative pole clamping metal of each wall scroll clamping LED assembly is communicated with through the cathode conductor layer; Through selecting the number of wall scroll clamping LED assembly, make up its relative position, promptly can design the plane lamina led light source that has conductive pattern.Each wall scroll clamping LED assembly can freely carry out series-parallel circuit as required and connect, and is convenient to the processing of property in batches.
The order of said LED lamp pearl is more than one; It can be on the every wall scroll clamping LED assembly plurality of LEDs lamp pearl to be set, and can also be the many wall scroll clamping LED assemblies that are provided with a LED lamp pearl.
A kind of this method of clamping thin slice LED pasting method comprises the steps:
(1) shiny surface one side with the clamping metal is positioned at the below, in anodal clamping metal and negative pole clamping metal, inserts LED lamp pearl to be installed;
(2) adjustment insert behind the LED lamp pearl the clamping metal towards, make a side that has groove be positioned at the below, cooperate push action, prevent that LED lamp pearl from coming off;
(3) adjustment LED lamp pearl position makes LED lamp pearl be positioned at groove, pushes the clamping metal, pre-fixes the position of LED lamp pearl, forms wall scroll clamping LED assembly;
(4) to anodal clamping metal and the energising of negative pole clamping metal, the welding of switching on forms clamping plane lamina LED paster structure.
Above-mentioned LED method for sealing, operating process is comparatively simple, and paster when being applicable to many LED lamp pearl can adapt to the automatic batch production requirement.
If wall scroll clamping LED assembly is more than two, it has two kinds of methods in the processing of step (4):
First method: earlier will be after all the anodal clamping metals of wall scroll clamping LED assembly in the step (3) pass through the cathode conductor layer through cathode conductor layer connection, all negative pole clamping metals, the welding of switching on again;
Second method: the wall scroll clamping LED assembly that will in step (3), obtain the earlier welding of switching on, again all anodal clamping metals are communicated with through cathode conductor layer, all negative pole clamping metals are communicated with through the cathode conductor layer.
The product properties that above-mentioned two kinds of methods obtain is the same, is difference slightly on the processing sequence.
In any case wall scroll clamping LED assembly can use as LED luminous lamp strip independently, it has the both positive and negative polarity that can connect through lead, through lead or metal pair its carry out also, the connection of series circuit, both can realize design to its circuit.
Beneficial effect: the clamping thin slice LED paster structure that the utility model provides, luminous efficiency is high, heat dispersion is strong, and has certain flexibility and mechanical strength; The clamping thin slice LED encapsulation pasting method that the utility model provides, process is simple, can carry out paster to a plurality of LED wicks, is suitable for producing in batches.
