Description of the new type: [Technical field to which the new type belongs] A lamp current sharing application circuit, especially a connection relationship between a plurality of transformers and a plurality of lamps, for adjusting the electricity generation between the plurality of lamps: Hengzhi's lamp current sharing application circuit. s ”Machine Flat [Previous Technology] Due to technological advances and consumer demand, the size of LCD panels is so large that single-lamp tubes can no longer meet their lighting requirements, so two or more lamps need to be used. In order to ensure the brightness of LCD panels In the same sentence, the current of each lamp must be adjusted so that the amount of current flowing through each lamp is equal to that of the cold cathode fluorescent lamp (CCFL), which is highly unstable and negative: It is difficult to maintain the same lamp impedance, causing = the current cannot be equal. In addition to the uneven current between the lamps, in addition to the unevenness of the current, lamps with too much current will also shorten the length and make the lamps age. The speeds (AgingRate) are inconsistent. However, it is a conventional method to use a differential ballast to adjust two two: = diagrams. It includes a first coil with a first coil ㈣ and a transformer 12 ′ first coil ⑵, one end of which is connected: parent Current source 1Q, the other end is connected to the first tube ⑷ = the other end of the lamp 141 is connected to the reference potential G. and a first position G. As described above, the other end of 42 is connected to the reference Electric first-line ... second ': turn again ^ provides stable current L, ί2 are used for the second differential ballast, which are used separately, and s 141 and the second lamp 142 use M265740, so that the current flowing through the first lamp 142 and the second lamp 142 is balanced. The effect is shown in the picture. Please refer to the second picture, which is a schematic diagram of the equivalent magnetic circuit of the transformer 12 in the first picture. As shown in the second picture, the magnetic core 12 ° includes two side posts. A1 and A2, and the two shoulder posts A3 and A4. When the currents I ,, ^ are the same, t, and f pass through the first coil 121 * the current of the second coil 122 is also equal to '' and '' Baozhou _ L · in the first-coil The magnetomotive force generated by 121 is also equal to the magnetomotive force generated by the current l in the second coil 122, that is, the magnetomotive force in ㈣A1 'and the magnetomotive force in side pillar A2 cancel each other, so the shoulder post A3 and the shoulder There is no magnetic flux in Central A4. At the same time, the magnetic flux in side column A1 and side column A2 ① φ φ 2. The loop can be completed through the outer air gap, but because the magnetic resistance of air gap is very high, this The inductance effect caused by the circuit can generally be ignored. Please refer to the first picture in Figure 2. Please refer to the third picture of McCaw, which is the first picture of the equivalent magnetic circuit connection kg. When the current I! Of the first lamp tube 141 is different from the current 12 of the second lamp tube 142, the magnetomotive force generated by the current h on the first coil 121 and the current l2 on the second coil 122 The generated magnetomotive forces are also different, that is, the magnetomotive forces in the side column A1 and the side master A2 are not equal. The difference between the two is added to the side column A1, record A2, shoulder column A3, and shoulder column M. Low-resistance loop to generate a large amount of magnetic flux ①, the magnetic flux ❿ cuts the first coil ^ and the second wire mesh 122, and induces between its ends-a correction pressure ^ This correction voltage forces the first lamp The current of the tube 141 is equal to that of the current of the first tube 142. ^ Refer to the fourth figure, which is a schematic diagram of a conventional simple circuit using a differential ballast to regulate the complex k-element current. The simple circuit shown in the fourth figure includes M265740 including a plurality of first coils 121 and a second coil. In the transformer 12 of the coil 122, one end of the first coils 121 is connected to a reference potential G, the other end is respectively connected to a first lamp tube 141, and the other end of the first lamp tubes 141 is connected to an AC power source 10. And one end of the second coils 122 is connected to the reference potential G, and the other ends of the second coils 122 are respectively connected to a second lamp tube 142, and the other ends of the second lamp tubes 142 are connected to the AC power source 10. As described above, the AC power source 10 forms a differential ballast through the first coil 121 and the second coil 122 of the transformers 12 to provide stable currents h and I2 to the first lamps 141, respectively. Use with these second lamp tubes 142, so that the current flowing through the first lamp tube 141 and the second lamp tube 142 achieves the effect of balancing. It is limited to the current between the two lamps and cannot be balanced with other lamps. effect. Please refer to the fifth figure, which is another simple circuit diagram for adjusting the lamp current using a differential ballast. As shown in the fifth figure, two lamps are used as an example. The two lamps 31 and 32 are connected in parallel. The high-voltage ends of the two lamps 31 and 32 are connected to an AC power source through a differential ballast element 39. 10. The differential ballast element 39 can generate a correction voltage that is proportional to the mismatch between the lamp currents 131, 132 and can be superimposed on a common drive voltage. Therefore, after the modified driving voltage, the currents 131 and 132 of the lamps can be adjusted appropriately to make them evenly distributed. Although this circuit can ensure that the currents of the two lamps are equal, their structure generally includes a specific shape of the magnetic core and the coil frame, and these magnetic cores and coil frames are not generally standard products, so that in the material arrangement and cost control All are inconvenient. Please refer to Figure 6, which is another simple circuit diagram for adjusting the current of multiple lamps using a differential ballast. As shown in the sixth figure, a plurality of differential M265740 dynamic ballast elements (Ti, T2, and Td are connected to the cross-connect # 'T5'T6'T7) are tree-shaped to achieve the current balance U: 2, L3 , L4, L5, L6, L7. The operation principle is the same as that described in the fifth figure. The conventional shovel _M and official current circuit in the above description has a common gap: when it is above multiple lamps, it can only Application == Can be applied to an odd number of lamps, and the number of lamps in the sixth figure is shown. * Li Bai is different and can only be applied to two times.

At the same time, the other side of the transformers are connected to form a closed circuit. Here, the Hai power source provides the same current to the lamps. The lamp current sharing application circuit used in the creation of electric books has a plurality of embodiments. The-terminal of the lamp is connected to the-one of the plurality of transformer groups = one end of the winding on one side of the transformer and the other end of the winding on one side is connected. To a power source, and the other windings of the transformers in the first plurality of transformer groups are connected in series to form a closed loop. At the same time, the other end of the lamp tubes is secreted to a second plurality of transformer groups. One side of the transformers is connected to the second side, and the other end of the I / Zewu group is connected to the second power source, and the brother: the windings on the other side of the transformers in the plurality of transformer groups are connected in series. Therefore, the first power source is the same as the second power source. The working current reaches these lamps. = Creative department, the closed loop formed by this group in series using the electromagnetic induction characteristics of the inkjet device, so that the current flowing through the winding _ ㈣ 1 is applied to the other side windings On the other hand, / The same day Shouben creative department can be applied to the odd or even number of lamps two, the Asian Ambassador lamp tube to achieve current sharing balance, and then the second brother = :; r coils must have different shortcomings on paper. G 上The number of lamps can only be applied to the power of two. In order to understand the content of the technical review 1 # _, you can understand the characteristics of the abstract and the technical drawings. Only the table test is provided. * ㈣ 与 附 ® 'However ^ " brother Ming It is not used to limit the creation of M265740 system. [Embodiment] = Refer to the diagram of Leqi, which is the schematic diagram of the current sharing and application of the two lamps in this creation. The element of the seventh diagram > + μ " ^ Bad circuit Take two lamps as an example, which includes two lamps 3 L2), one end of the two lamps (LI, L2) is connected to a power source, and the other end is connected to one side of the transformer (Π, Τ2).

Through the transformer (T1, T2) electromagnetic induction characteristics and through these transformers (T1, T2)-side windings (Lis, L entangled closed loop formed by the closed circuit), so that one side winding (Lls, L2s) flows through The currents ix are equal. By using =, the power source Vsec provides the same working current (ii, i2) to the two lamps (U, L2). In the above description, the transformers (T, T2) have winding turns on both sides They are equal and equal transformers. At the same time, the two lamps (LI, L2) can be cold cathode tubes (CCFL) or external electrodes (EEFL). e ▲ Stomach, please refer to the seventh picture, where the transformer (T1, T2) is a two-balanced transformer, so the number of windings E on both sides of the transformer T1 is equal (Nlp = number of windings on both sides of the Mt. Takayama transformer T2). Equal (N2p = N2s), so it can be known that the equivalent inductances on the windings on both sides of the transformer will also be equal, as shown in the following formula G): LIp—Llsj L2p ~ L2s (1) ^ surface type In sub-section (1), LIp and Lis represent the equivalent inductance settings on the windings on both sides of the transformer T1, and L2P and L2s represent the equivalent inductance values on the windings on both sides of the transformer T2. If yes, in the case of transformer T1 and transformer T2, the equation (1) can be written as shown in the following equation (2):, M265740 L1p = L1s = L2p = L2s (2) At the same time, because transformer T1 and The equivalent inductance value of the transformer T2 winding is equal, so the mutual value (MI, M2) generated between the windings on both sides of the transformer (Ti, T2) will also be approximately equal, as shown in the following formula (3) : M1 = M2 (3) In the above formula (3), M1 is the mutual inductance value between the windings on both sides of the transformer τΐ, and M2 is the mutual inductance value between the windings on both sides of the transformer T2.
