Red and blue double flashing patch LED 2835

Red and blue double flashing patch LED 2835 Light Emitting Diode SMD What is LED drive power The LED drive power supply converts the power supply into a specific voltage and current to drive the LED to emit light. Under normal circumstances: the input of the LED drive power includes high-voltage power frequency AC (ie mains), SMD LED lights low-voltage DC, high-voltage DC, low-voltage and high-frequency AC (such as the output of an electronic transformer), etc. The output of the LED driving power supply is mostly a constant current source that can change the voltage with the change of the forward voltage drop of the LED SMD LED lamp beads. The core components of the LED power supply include switching controllers, inductors, switching components (MOSfet), feedback resistors, input filter components, output filter components, and so on. According to the requirements of different occasions, there are also input over-voltage protection circuits, input under-voltage protection ci…
