Color-changing LED bulb

A color-changing LED bulb that comprises a light-emitting component, electrified components that are mounted below the light-emitting component, a lampshade that covers the light-emitting component, a component loading board having a power cord extending from the loading board, connected to the electrified components and including input lines, a chip bridge rectifier, a chip resistor, an IC chip and multiple light beads of different colors mounted at the top of the component loading board, the chip bridge rectifier being connected in parallel with the input lines, the chip resistor is connected in a series circuit with the chip bridge rectifier, the IC chip controlling light emission of the bead, a switch for controlling a light output from the bulb and capable of being turned on and off, a detection block for detecting the turning on of the switch;

• and a lighting control block for controlling the light beads, the lighting control block including a memory circuit for counting a number of times that the switch is operated so that, if there is at least a predetermined interval between switch activations, the next time that the switch is operated, the same color is displayed.
