The AC power supply through a resistance capacitance step-down unit after this, signal display and a bridge rectifier, it is used to charge the battery, the switch, when the switch is open, closed ahead, a group of light emitting diode connected to the work below, this is due to the reverse cutting diode D5 check, above a group is not working; when the switch is closed due to backward, forward by D5, the two groups of light emitting diodes are given the same power and work. That’s the flashlight. There are two different kinds of light<\/a>. The main function of D5 is to use its reverse cut-off characteristic to limit the work of a part of the circuit to achieve the function of regulating the light source.
\nThe following nutrient is called a power supply circuit, which is called a working circuit. The detailed principle description, is the most basic concept, in any one of the information on the basis of electronic or application of the information, there is interest, then you can find a.<\/p>\n","protected":false},"excerpt":{"rendered":"
