| 摘要 | A lighting apparatus includes an input power terminal, a light source element coupled to the input power terminal, and a current bleeder module that is connected to the input power terminal and is configured to draw a current from the input power terminal responsive to a phase cut input power signal received at the input power terminal during a first portion of a period of the phase cut input power signal and is configured as an open circuit so as not to draw current from the input power terminal during a second portion of the period of the phase cut input power signal. | ||

| 主权项 | 1. A lighting apparatus, comprising: an input power terminal; a light source element coupled to the input power terminal; and a current bleeder module that is connected to the input power terminal and comprises a detector circuit that is configured to detect a change in voltage per unit of time of a phase cut input power signal received at the input power terminal, the current bleeder module being configured, responsive to the change in voltage per unit of time of the phase cut input power signal, to draw a current from the input power terminal during a first portion of a period of the phase cut input power signal and being configured as an open circuit so as not to draw current from the input power terminal during a second portion of the period of the phase cut input power signal. | ||
