    摘要: A dimming light emitting diode (LED) system comprises an LED driver. A switch-mode power supply controller is coupled to the LED driver to drive an LED light source array. The LED driver is configured to output an LED drive command to the switch-mode power supply controller to dim the LED light source array based on one or more LED parameters. The one or more LED parameters include a photometric response parameter, a gamma parameter, an aging parameter, a temperature parameter, or any combination thereof.

    摘要: LED driver apparatus and methods may include a sensing circuit for adjusting an output based on either a pulse width modulation dimming control or an analog dimming control. An LED driver apparatus and methods may also include a sensor for a parameter such as temperature and for recording such parameter, for example as a function of time. A setting unit for an LED driver apparatus can be used to sense and/or adjust settings in the LED apparatus even when the LED apparatus is not independently powered.

    摘要: Methods and apparatus are described that can provide improved power factor correction and total harmonic distortion, efficiency and/or direct feedback of load current variations to a power source inverter. In one example, a power supply, for example, a ballast, can have an input circuit, an output circuit and an inverter circuit coupled between the input circuit and the output circuit. A current feedback circuit is coupled between the output circuit and the inverter circuit and configured to feed current back to the inverter circuit through a transformer stage separate from the inverter as a function of a current level in the output circuit.
