The transformer has a coil base with a primary line area and a secondary line area on it, and a plurality of terminals are provided at both ends for connecting the wires of the winding. and soldered to the circuit board. Due to the continuous advancement of technology and the demand for high brightness of LCD displays, some manufacturers have increased the number of lamps used in the backlight module of LCD displays, and the number of transformers used will also increase. In this way, Not only the size of the liquid crystal display becomes larger, but also the relative weight becomes heavier. Therefore, some operators will use a single transformer to drive multiple lamps. If the above-mentioned transformer is used to drive multiple lamps, the voltage of the transformer must be increased to match its high power output; therefore, using a single transformer to drive When there are multiple lamp tubes, the primary coil and the secondary coil are wound on the same bobbin, so that the winding area of the primary coil is limited. Therefore, if the voltage output is increased according to the needs of the transformer, the primary wire area and the secondary wire area The number of coils on the transformer must be increased, which leads to an increase in the thickness of the transformer and a relative increase in its overall volume.

Secondly, when the load power increases, the primary coil part will have an obvious temperature rise problem, which may cause the transformer to overheat. If the wire diameter of the primary side winding coil is thickened, the problem of temperature rise can be solved slightly, but the thickness of the coil is increased, which makes the thickness of the transformer even more; in addition, in the above common transformers, if it is necessary to consider The safety isolation between the primary coil and the secondary coil on the same bobbin is more difficult in the withstand voltage of the high-voltage winding, which has a relatively adverse impact on the manufacturing and cost of transformer parts. Therefore, how to solve the above-mentioned problems has always been an urgent solution and improvement that the industry needs to seek.
