    摘要: A power converter includes first and second circuit modules, a first capacitor, a second diode and a control module. The first circuit module includes a switching element in parallel with a first diode. The second circuit module includes a first inductor and the first circuit module. The inductor is in series with the first circuit module. The first capacitor is in parallel with the second circuit module. The second diode includes a first terminal and a second terminal, where the first terminal is in series with the second circuit module and the first capacitor, and the second terminal is coupled to a second power terminal. The control module varies one or more of the first capacitor and the first inductor based on at least one of a current of a load circuit or an input voltage. A resonating waveform is generated by a resonant circuit of the second circuit and is used by the control module to turn off the switching element under zero-current and zero-voltage conditions.

    摘要: An LED lamp includes an optical part, a heat dissipation part and an electric part. The optical part includes main and auxiliary LED light sources thermally attached to the heat dissipation part. The electric part includes a rechargeable battery and a circuitry for converting an external AC power source into first and second DC power sources. The auxiliary LED light source is connected to the first DC power source for providing an auxiliary illumination when the external AC power source is normally supplied or to the rechargeable battery for providing an emergency illumination when the external AC power source is interrupted. The main LED light source is connected to the second DC power source for providing normal illumination when the external AC power source is supplied normally. Photoelectric switches are also provided for controlling the action of the auxiliary LED light source.
