![]() This can also take from a few seconds to several minutes. ![]() ![]() As a result the LED continues to light until the energy stores are discharged. These components can serve as a storage for electrical energy.ĭepending on the design of the driver circuit, these components may still be active when the input voltage is switched off by pressing the light switch. The driver contains various components including capacitors and inductors. This generates the operating current required for the LED ( light emitting diode). A common reason for flickering T8 LEDs is a loose connection within the circuit. Check your lamps, wires, ballast/driver, and tombstones for bad connections or loose wires. LED bulbs and luminaires are equipped with an electronic circuit called LED driver. The first step to identifying the problem is to evaluate your current setup. According to its wattage this leads to the afterglow effect from a few seconds to several minutes. Depending on the semiconductor material used, the luminescent layer can store a certain amount of energy in the form of visible light for a certain period of time. To produce white light usually blue light emitting diodes are used with an additional luminescent layer (phosphor layer). However, if the lamp goes out immediately when it is removed from the socket, the cause must be found in the electrical installation. If the bulb continues to glow weakly after removal, it is due to the luminescent layer or the LED driver. You can easily check this by removing the illuminant from the socket immediately after turning off the light switch. The first two reasons can be found in the LED light itself.
