    • A power conditioning circuit in a light bulb efficiently converts an Alternating Current (AC) input voltage into Direct Current (DC) power for operating LEDs in the light bulb. The power conditioning circuit discharges capacitors when a voltage level of the input voltage drops below a given voltage necessary to operate the LEDs. The capacitors are then recharged when the input voltage is high enough to power the LED. The capacitors are configured to operate as voltage dividers while being charged thus reducing a peak voltage level of the output voltage used for powering the LEDs. The reduced output voltage reduces the overall amount of energy used by the light bulb and reduces the amount of heat radiated by the light bulb.
    • 灯泡中的功率调节电路将交流(AC)输入电压有效地转换成直流(DC)电源,以在灯泡中操作LED。 当输入电压的电压降低到操作LED所需的给定电压时,功率调节电路对电容器进行放电。 然后当输入电压足够高以为LED供电时,电容器被再充电。 电容器被配置为在被充电时作为分压器操作,从而降低用于为LED供电的输出电压的峰值电压电平。 降低的输出电压降低了灯泡所使用的能量的总量并且减少了由灯泡辐射的热量。
