A LED bulb includes a bulb head, a power PCBA of which a bottom is equipped with power pins, a LED PCB mounted to a top of the power PCBA and electrically connecting with the power PCBA, and a cover covered on the LED PCB. The bulb head includes a housing, electrical terminals disposed in the housing and including an anode terminal and a cathode terminal, and a power connection unit mounted to a bottom of the housing and including a bulb base and an anode element. One end of the anode terminal is electrically connected with a top end of the anode element. One end of the cathode terminal projects outside the housing to be electrically connected with the bulb base. The power PCBA is mounted on the housing. The power pins are electrically connected with another two ends of the anode terminal and the cathode terminal. |
