How to judge the flashing of LED lamps
1. Confirm whether the driving voltage and current required by the series-parallel number of LED lamps
are within the nominal range of the output parameters of the LED driving power supply. If it exceeds the nominal range, it may cause the problem of light flashing.
2. Confirm the wiring voltage drop range in the entire lighting circuit, that is to say, measure the actual voltage of the lamp bead string farthest from the LED drive power supply, plus the wiring voltage drop should be within the maximum output voltage range of the LED drive power supply. If it exceeds the maximum output voltage of the LED drive power supply, it will cause the light to flicker.
3. Confirm that the working environment of the LED drive power supply is in line with the requirements of its specification. For example, the range of the input AC voltage, too high or too low input voltage will trigger the undervoltage and overvoltage protection of the LED drive power supply; the working ambient temperature has dissipated heat. environment, the working environment temperature is too high or the heat dissipation environment is not ideal, such as airtight, no air circulation and other heat dissipation environments may trigger the overheat protection circuit of the LED drive power supply, thus causing the light to flicker.
4. Confirm whether the control system or dimming system matches the LED driving power supply. Different control systems or dimming systems have different requirements for the LED driving power supply. value, frequency, conformance of the interface.
