摘要： In a circuit arrangement for operating light sources, inexpensive technologies for power factor correction can be used in combination. Owing to the combination of a dual charge pump and a valley fill circuit it is also possible to adhere to relevant standards for rated current harmonics even at rated powers of over 25 W whilst maintaining low component loading.

摘要： An LCD apparatus includes a light source generating light, a driver circuit and an LCD panel. The driver circuit includes a driving voltage control section and a driving voltage generating section. The driving voltage control section senses an environmental temperature and outputs a control signal having a level which is adjusted based on a comparison of the environmental temperature to a reference temperature. The driving voltage generating section is electrically connected to the driving voltage control and generates a driving voltage based on the control signal. The LCD panel displays an image by using the light generated from the light source. Channeling that induces deterioration of display quality is prevented by adjusting an operating frequency of the light source according to the environmental temperature.

摘要： A LED driver includes a high frequency inverter and an impedance circuit. The high frequency inverter operates to produce a high frequency voltage source whereby the impedance circuit directs a flow of alternating current through a LED array including one or more anti-parallel LED pairs, one or more anti-parallel LED strings, and/or one or more anti-parallel LED matrixes. A transistor can be employed to divert the flow of the alternating current from the LED array, or to vary the flow of the alternating current through LED array.

摘要： The power supply (20) for LEDs provides power to a LED light source (10) having a variable number of LEDs wired in series and/or in parallel. The power supply (20) uses current and voltage feedback to adjust power to the LEDs and provides protection to the LED light source (10). A feedback controller (27) compares sensed current and sensed voltage to a reference signal and generates a feedback signal, which is processed by a power factor corrector (124) to adjust the current flow through the transformer supplying current to the LEDs. A LED control switch (24) clamps a peak of the current to the LEDs to provide further protection to the LED light source (10). A short/open detection circuit (30) indicates any detection of a “LED outage” of the LED light source (10).
