摘要： A dimmer switch (110-x, 200, 400, 600, 700A, 700B,1200) adapted to be coupled to an alternating current (AC) source and to a load so as to control an amount of power delivered from the AC source to the load, the dimmer switch may include: a triode for AC (TRIAC) (208, 408, 612) coupled between the AC source and the load, and which when triggered conducts to deliver a controlled amount of power from the AC source to the load for a corresponding half-cycle of one or more half cycles of the AC source. The dimmer switch may include first and second triggering circuits (606, 608) configured to trigger the TRIAC when charged after being enabled. One or more of the triggering circuits may be a self-balancing triggering circuit. The dimmer switch may further include a controller (412, 602, 1210) which selects and thereafter enables one or more of the first or second triggering circuits.

摘要： A dimmable ballast circuit for a compact fluorescent lamp controls the intensity of a lamp tube in response to a phase-control voltage received from a dimmer switch. The ballast circuit comprises a phase-control-to-DC converter circuit that receives the phase control voltage, which is characterized by a duty cycle defining a target intensity of the lamp tube, and generates a DC voltage representative of the duty cycle of the phase-control voltage. Changes in the duty cycle of the phase control voltage that are below a threshold amount are filtered out by the converter circuit, while intentional changes in the duty cycle of the phase control voltage are reflected in changes in the target intensity level and thereby the intensity level of the lamp tube.

摘要： A method for operating a fluorescent lamp (5) having a nominal power (WLa) and stabilized with an EM ballast (B) comprises the steps of, during normal operation, short- circuiting the lamp during a closing time interval (CTI) during each current period in order to operate the lamp at a reduced power. The method comprises the step of detecting whether the lamp is stabilized by means of an inductive ballast or by means of a capacitive ballast. If it is found that the ballast is capacitive, the timing of the closing time interval (CTI) is set such that the closing time interval (CTI) has a first closing time segment (CTS1) immediately before a zero-crossing of the current, having a first duration (?1) higher than zero, and a second closing time segment (CTS2) immediately after said zero-crossing of the current, having a second duration (?2) higher than zero.

摘要： The present invention relates to a dimmer control circuit (100) capable to detect whether a phase-cut dimmer is connected using an average signal (VDCI) derived from the mains voltage. The average signal (VDCI) or a signal (VDCI_ls) derived from (VDCI), ranging from a minimum value to a maximum value, is compared to a dimming threshold (Vdim_th) through a phase-cut detecting unit (20). The comparison result is used to control the state diagram of a dimmer control logic (40) by selecting the step dimming mode (STD) or the phase-cut dimming mode (PCD). The output (OUT) of a switching unit (30) is determined by the state diagram of the dimmer control logic (40) in such a manner that the phase-cut dimming mode (PCD) is prioritized above the step-dimming mode (STD) and the maximum level of the STD states is depending on the mains voltage and application adjustable.

摘要： A dimmer switch for controlling the intensity of a dimmable screw-in compact fluorescent lamp provides smooth dimming of the fluorescent lamp and prevents flickering of the lamp due to multiple re-strikes. The dimmer switch prevents multiple re-strikes by avoiding multiple firings of a controllably conductive switching device of the dimmer circuit by limiting the high-end light intensity of the fluorescent lamp. Specifically, the dimmer switch limits the length of a conduction interval of the controllably conductive switching device to less than approximately 75% of each half-cycle. The dimmer switch may include a user-accessible adjustment actuator for changing the dimmer switch between an incandescent operating mode and a screw-in compact fluorescent mode. The dimmer switch may also be operable to automatically change the dimmer switch between the incandescent operating mode and the screw-in compact fluorescent mode by detecting the occurrence of the multiple firings of the controllably conductive switching device.

摘要： A power regulator (20) for use with an AC power source includes a voltage converter (24) having a first input (26) and a second input (29). The first input (26) is connected with the AC power source and receives AC current therefrom. The second input (29) is connected to a controller (22) and receives a control signal therefrom. The voltage converter (24) generates a substantially sinusoidal regulator output signal (28) the amplitude of which is responsive to the control signal. The power regulator (20) also includes a controller (22) having a first input (27) and a second input (25). The first input (27) receives a set point signal. The set point signal determines the amplitude of a substantially sinusoidal reference signal which is substantially in-phase with the regulator output signal. The controller (22) generates the control signal indicative of the instantaneous difference between the regulator output signal and the amplitude of the substantially sinusoidal reference signal. The amplitude of the substantially sinusoidal reference signal is independent of the amplitude of the AC power source and the amplitude of the regulator output signal.
