New description: [New technology field] The drive circuit, and the kind of drive circuit, especially related to the kind of light-emitting diode, need not consider the polarity matching problem between the light-emitting diode and the power supply. [Prior Art], the main input _: ^ turn the wafer composition, the semiconductor material will pass through the various techniques lx ^ pn structure. The light-emitting diode is applied to the library = display. For example, traffic status indicators, continuous indicator lights, light strips, thin and light message boards, and the like. In addition to the consumption of the light-emitting diode, the LED can also extend the position of the indicator light. Because the indicator light is composed of a number of light-emitting diodes, so when the first diode of the μ is burned, it does not affect the overall operation of the indicator light. Since the voltage-current characteristics of the light-emitting diode are similar to those of a normal diode, the relationship between the electric current and the current is approximately an exponential curve, so a small voltage will generate a large current. Further, the temple considers the characteristics of the light-emitting diode, so it is difficult to use an AC power to supply power to the light-emitting diode. Because such a job may exceed the maximum amount of current, the first diode is burned. Because • current is in logarithm _, and the entire working area of the polar body, the voltage can be considered constant. - The existing light-emitting diode bulb can't be directly under the AC power supply, and then the electric power wire (or the rectification H) is used to make the AC power to be directly riding. Because additional equipment is needed to convert AC power into DC power, the overall manufacturing cost of M324374 is higher. [New content] The main purpose of this new model is to provide a kind of LED driving circuit. There is no need to consider the polarity matching problem between the LED and the power supply. In order to achieve the above, a light-emitting diode driving circuit disclosed in the present invention is
