目β 陰極4管多半疋做為液晶顯不器(LCD)之背光源使用，但礙於 冷陰極燈管形狀係為長條狀，而液晶顯示器(LCD)係為面狀，故若要讓整個 液晶择員示為(LCD)有完整面狀的光源產生，則勢必使用多支冷陰極燈管並排 組成面狀方可達成。所以，如何能讓液晶顯示器整個畫面的亮光均相同， 則所有並排組成的冷陰極燈管需具有相同的輝度才可達成。 一如「第1圖」所示，係為習知平衡電感結構與冷陰極燈管配接簡化電 路不意圖；由圖可看出，習知的平衡電感1〇a、结構，一般係以兩條相同線 從的線體100a(如：漆包線)纏繞相同的醜於一個繞線管化上，並以一個 間隔板110a將其隔開，以及一個穿設該繞線管Ua内且可於該繞線管 内外^生封閉磁路的鐵芯組12a所構成；而在該配接簡化電路示意圖中可 知，右要使该四支(CCFL)冷陰極燈管20點亮，除需以高壓變壓器丨所轉換 ^出的壓驅動外’尚需藉由三個平衡電感術，方可使該四支冷陰極燈 盲20輸出的冗光達成輝度相同的目的。由此可知，此三 此電路中，即為讓此四支冷陰極燈管20達到輝度相同的重千要衡因=在 接者再仔細看此電路示意圖，當高壓麵器！輸出電流於輸入端A後， 赴端A的私流會一分為二給第一輸入端B1及第二輸入端B2(即：A B2 ^Γ'1 ·點的電流+B2點的電流）；但因第一輸入端B1及第二輸入端 里/ 載不同[即冷陰極燈管2〇於生產時，阻值(Ω)的誤差而造成的差 二β弟―輸入端B1與第二輸入端Β2的電流有所不同(即：Β1點的電 1矜入ΓΓ電流）；因電流經過平衡電感池而分流至第—輸入端B1及第 二^入姓上，故此時平衡電感即可發揮作用令第—輸入端B1與第 &的電流達成平衡而相同(即：B1點的電流=B2點的電流）。而當 B1的電流流至第—輸出端C1及第二輸出端Ο後，此時第_ 月⑽的電流會一分為二給第一輸出端α及第二輪出端c2(即⑻點 5 M289904 的電流=CI點的電流+C2點的電流);但因第一輸 _«不同，而使第-輸出端α與第二輸出Most of the cathodes of the cathodes are used as backlights for liquid crystal display (LCD), but the shape of the cold cathode lamps is long, and the liquid crystal display (LCD) is planar, so The entire liquid crystal display is shown as a (LCD) full-surface light source, which is bound to be achieved by using multiple cold cathode lamps side by side to form a surface. Therefore, how to make the brightness of the entire screen of the liquid crystal display the same, then all the side-by-side cold cathode lamps need to have the same brightness to achieve. As shown in Figure 1, it is not intended to simplify the circuit of the conventional balanced inductor structure and cold cathode lamp; as can be seen from the figure, the conventional balance inductor 1〇a, structure, generally two The wire 100a (eg, enameled wire) from which the same line is wound is wound on the same ugly wire and separated by a spacer 110a, and one is passed through the bobbin Ua and can be The core group 12a of the closed magnetic circuit is formed inside and outside the bobbin; and in the schematic diagram of the simplified circuit, it can be seen that the four (CCFL) cold cathode lamp 20 is illuminated right, except for the high voltage transformer. The three voltage-inductive techniques of the four cold cathode lamps are required to achieve the same brightness. It can be seen from this that in the three circuits, the four cold cathode lamps 20 have the same brightness and the same weight. In the receiver, look at the circuit diagram carefully, when the high pressure surface device! After the output current is at the input terminal A, the private stream going to the terminal A is divided into two to the first input terminal B1 and the second input terminal B2 (ie: A B2 ^Γ'1 · point current + B2 point current) However, because the first input terminal B1 and the second input terminal have different loading/loading [that is, the cold cathode lamp 2 is in production, the resistance value (Ω) error is caused by the difference of the two brothers - the input terminal B1 and the second The current at input terminal 有所2 is different (ie: Β1 point of power 1 ΓΓ ΓΓ current); because the current is passed through the balanced inductor pool and shunted to the first input terminal B1 and the second input last name, so the balance inductance can be The function is to make the first input terminal B1 and the current of the & balance the same (ie, the current at point B1 = the current at point B2). When the current of B1 flows to the first output terminal C1 and the second output terminal, the current of the first month (10) is divided into two to the first output end α and the second round end c2 (ie, (8) point. 5 M289904 current = CI point current + C2 point current); but because the first input _« is different, the first output end α and the second output

Similarly It can be seen that the current of the second round input terminal B2 flows to the third round output terminal C3^: TC2 point end C4, after the balance is balanced by the balance inductor, the current of the third round- That is: [3 points of the current 々 point ^ 40 out of the creep C4 mm, ^ electric two =, the current C4 of the current C4", the current = C3 point current two C4 point current). Such as ",, the brightness of the output of the cathode lamp 20 achieves the same purpose. σ ~ four cold touch this feather 4 can know the importance of the 5 Hai balance inductance 1 〇 a in the balance of the cold cathode lamp 20 ^ Into, · Heng inductance ^ can have this effect, but in terms of its construction... cold Yin "tube 20 rounds of light = degree =, then you need to use three conventional balance inductance he, and each = have different iron The core group 12a, the core circuit loss caused by the core group ' will be the sum of the three magnetic circuits of the three balanced inductors, which affects the cold cathode. The power output by the tube 20. -, =21 The current of the cold cathode lamp 20 of three or more is required to be achieved by using two well-balanced inductors 10a, and each of the balanced inductors requires each bobbin. Na and iron core group 12a can be combined with the line body to form a flat m:1 system, resulting in a lot of material costs and waste of manufacturing man-hours. Really light bribes to decide the money - the big subject. The purpose is to solve the above problems and avoid the problem. The new type, the magnetic flux and the magnetic flux direction are the same, which can reduce the difference between the multiple M289904 and the same power and brightness. The same purpose ^."b(ccfl) uses 'to make each cold-cathode tube achieve a high-round tube inside and outside the formation of a magnetic contact ς group through the bobbin and can be placed on the winding = upper foot, which Each of the flats is provided with a plurality of wires for inputting and outputting currents, and i-body two of the same number of turns are provided with two identical wires that are blocked by the spacer plate, and The two ends of the line body are electrically connected to each of the connecting legs respectively. More than one of the same: 3: In this new type of loss Balance _ 'Because you can provide more than two conventional cold-cathode tubes, you need to use more than two to achieve, so you can take the shirt ~ ^ type multi-output balance electric m gamma - one can take the effective and painful manufacturing hours And material cost. Figure 2 is a schematic diagram of the appearance of the new multi-output balanced inductor. For example, the multi-output balanced inductor 10' of the bungee diagram is used to generate the same current output for each cold two. L1) Multi-output balanced inductor with the same brightness 10 'The balance inductor 10 is the best structure of the two e-type spliced iron core group 12 (this type is the new eve = other jobs), its towel, Wei line There are three mutual insulations on the #u: the inductance zone m' each of the balance inductance zones (1) is provided with a spacer 11〇, and each of the balance inductance zones m is provided with four wires for inputting and outputting currents. a foot m, the terminal leg (9) is embedded in the bobbin 11 and both ends are respectively exposed on the upper and lower sides of the bobbin 11; in addition, each of the balanced inductor regions 111 is respectively disposed at the interval The two phases of the plate 11〇 block === line body such as: enameled wire), and the line body The end system is respectively connected with each of the connecting legs (9) d. If yes, the outer casing of the wire-wound bobbin u can be wrapped with a casing 13 and then combined with two E-shaped irons. The core group 12 is disposed through the bobbin u to form a closed magnetic circuit inside and outside the winding officer 11; or the outer tube u is not covered with the casing U, so that the two E-shaped marriages can be M289904 The assembled iron core group 〖2 is provided with the bobbin 1 and the inner tube 11 forming a seal-way, which constitutes the multi-output balance inductor of the present invention. The figure shown in Figure 3 is the new multi-output balanced inductor structure and the aim. It can be clear that the new (four) fine balance inductor: the balanced inductance region 111' of the mouth of the mouth is interposed, and each of the balanced inductor regions 111 is provided with a partition plate 11G, and each of the balance inductance regions ill is provided with four The wheel 1 and the output electric slave are connected, and on each of the balanced inductor regions m, a wire body 100 (such as an enameled wire) with a resistance of the spacer plate is respectively wound and respectively connected to each of the connecting legs 1〇1 Electrically connected, and then the input terminal A, the first input terminal B1 and the second input terminal B2 of each of the pins 101 are like the input terminal A and the first input terminal B1 of the ""1" diagram> The second input terminal B2 & each point is connected to the high voltage (4) 1 to reduce the current/current, so that the single-recording balance can be achieved to reduce the magnetic path loss caused by a plurality of different conventional balances. And the magnetic sense ^ makes the four cold cathode fluorescent tubes 2G have the high output power and the same brightness, and the purpose of the effective ribs 'work time and material cost. The detailed description above is specific to the possible embodiments of the present invention, but the embodiment and the limitation of the special fiber B of the present invention are equivalent to the equivalent implementation of the spirit of the technique.
