摘要： A system for controlling solid state lighting including a source to supply any one of a range of AC or DC voltages to a plurality of light strings. The source includes a power factor correction circuit 14 for controlling the power factor to the system and a separate transformer for each light string. The current can pass through each LED string is independently limited by each corresponding LED driver circuit. The current through each LED string can be modified according to a feedback monitor system that measures parameters such as LED characteristics, forward current, temperature, and LED output intensity/color. Each LED string has an independent sensor that monitors the voltage across each switching device in the corresponding LED driver circuits and utilizes a control unit to control the voltages supplied by each corresponding transformer through control signals in response to the monitored switching device voltages.

摘要： A high intensity discharge (HID) ballast circuit comprises a trigger circuit, a power half-bridge self-excited oscillation circuit, which is arranged to enable self-excited oscillation by energizing an angle capacitor Cgs with a Miller capacitor Cdg of a power MOSFET when an original single pulse output by the trigger circuit is excited, and then output self-excited oscillation signals; and a filter loop which is arranged to match impedance for the self-excited oscillation signals, thereby converting a low-impedance voltage source to a high-impedance constant current source. The inherent phase relationship of the power MOSFET is utilized, and oscillation signals are generated by a power half-bridge self-excited oscillation circuit, and then impedance matching for the oscillation signals is performed by the filter loop, and finally an HID lamp is triggered. As a result, damages to human eyes caused by stroboscopic effect can be avoided and electro magnetic compatibility test can be passed.

The first period continues for at least two cycles, each cycle including a first sub-period during which the current is maintained in one polarity and a second sub-period during which the current is maintained in an opposite polarity. The second sub-period is shorter than and subsequent to the first sub-period. The second period, during which the current is maintained in a constant polarity, is as long as or longer than the first sub-period.

摘要： In one embodiment, a fluorescent lamp dimming circuit includes power factor correction control, dimming control, and switching devices. The power factor correction control may be connected to power factor correction circuitry that produces a regulated DC buss. The dimming control circuit may be connected to the input of the fluorescent lamp dimming circuit for producing a driver signal whose frequency varies depending on the input voltage waveform perhaps as modified by a dimmer. The control circuit may produce a drive signal with a duty cycle profile to drive switching devices. The switching devices invert the DC buss voltage to an AC voltage waveform for driving a resonant tank circuit. The resonant tank circuit may include an inductance, a capacitance, and the impedance of a fluorescent lamp. The AC voltage waveform when applied to the resonant tank circuit may cause the fluorescent lamp to dim based on the dimmer setting.
