Abstract
An LED bulb is described. The LED bulb comprises a shell, a plurality of LEDs within the shell, a driver circuit connected to the plurality of LEDs, and a base connected to the shell. The driver circuit comprises a first input to receive AC voltage, a second input to receive AC voltage, a neutral input, a power supply circuit connected to the plurality of LEDs, and a brightness control circuit. The brightness control circuit is connected to the first input, the second input, and the power supply circuit. The brightness control circuit is configured to output a modified AC voltage to the power supply circuit. The modified AC voltage is created by blocking a portion of a cycle of AC received by the first or second input. The blocked portion is based on whether the first input, the second input, or the first and second inputs are both hot.
