LED lights flashing common causes and treatment:
Energy-saving lamps, LED lights turn off the power after the flash, check the switch control is zero line. If the wiring is correct, refer to the following methods:
Usually the human eye can perceive light flicker up to 70 Hz, which is not perceived above this frequency. Therefore, in LED lighting applications, if the pulse signal frequency below 70 Hz low frequency components, the human eye will feel flicker. Of course, in a specific application, there are many factors that may cause the LED light to flash.
For example, in off-line low-power LED lighting applications, a common power topology is an isolated flyback topology. In the case of an 8W off-line LED driver reference design that conforms to the Energy Star solid-state lighting standard, the sinusoidal square-wave power conversion of the flyback regulator does not provide constant energy to the primary bias, the dynamic self-powered (DSS) circuit May activate and cause light to blink. In order to avoid this problem, it is necessary to allow the primary bias to be partially discharged in each half cycle, and accordingly, the magnitude of the capacitance and the resistance constituting the bias circuit needs to be appropriately selected.
