Nothing makes space go from splendor to squalor quicker than a flickering bulb.
It’s one of those things that you want to get fixing right away, so here’s a quick rundown of the reasons why your LED might be malfunctioning.
It’s useful to know that LED functions as a computer. It has a binary on and off status and no persistence like traditional light bulbs.
So if the on/off cycle, powered by mains alternating current (AC), is not functioning well, then the human eye sees the LED rapidly turn on and off, which we call flickering.
There are several reasons why the bulb is behaving this way, but mainly:
The low frequency of less than 50 Hz makes the LED bulb flicker. Your LED bulb might be flickering due to loose or incorrect wiring, incompatible dimmer switches, or bulb components such as a defective LED driver.
To cut to the chase, three points of fault usually make lights flicker. The fault could lie in the LED bulb, in the wiring, or in the current regulation.
Sometimes a short wire length within the light fixture could be at fault. It is a good practice to have all wires at least 6” long. Loose wires connecting the bulb, fixture, and switch could all be reasons for a sudden onset of flickering in your LED light bulbs.
Another thing that can cause flickering is the power factor, which is the efficiency of appliances in the circuit.
For example, having incandescent bulbs connected to the same circuit as LED lighting will make LED flicker. The reason is that traditional bulb uses 100% of needed energy, most likely 60W, leaving the rest of the supply for appliances such as LED lamps.
Having a couple of incandescent bulbs will quickly draw all the power leaving none to nothing for your LEDs, which will make them flicker due to the lack of power.
