Why does my LED light stay on?

LED bulbs and luminaires are equipped with an electronic circuit called LED driver. … Depending 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. As a result the LED continues to light until the energy stores are discharged.
