Zusammenfassung:Intelligent control of a solid state lamp when coupled to a trailing edge phase cut dimmer switch is provided. On and off cycles of the lamp's power stage switch are enabled during a period when the energy in the bulk capacitor is at its highest levels. During this period a bleeder circuit does not have to be enabled, which results in a greater operational efficiency as compared with normal switching schemes for trailing edge dimmers.
