Plural Load Device Regulation Patents (Class 315/294)
  • Patent number: 11363691
    Abstract: Apparatus and associated methods relate to powering a constant voltage DC load using a rectified output of a lighting ballast. In an illustrative example, the ballast may be configured to operate as a constant-current source. The DC load may, for example, comprise an array of LED strings connected in parallel. The number of LED strings may, for example, be selected to match a power output of the ballast. The number of LEDs in each string may, for example, be selected to match a rectified voltage output range of the ballast. A normally-open thermostat may, for example, be connected in parallel between the ballast and a rectifier and be configured to short-circuit the ballast if the circuit overheats. Various embodiments may advantageously utilize existing power processing functions of an electronic ballast to reduce complexity of a driver circuit for a constant voltage DC source.

  • Patent number: 11297703
    Abstract: Methods and systems for improved dimming of LED based illumination devices are described herein. An AC input voltage provided to an LED driver is rectified and the rectified signal is divided down by a voltage divider circuit to supply electrical power to a dimming interface circuit. The fraction by which the voltage divider circuit divides down the rectified signal is controlled by a Dynamic Input Voltage Compensator (DIVC) based on the peak value of the rectified signal. In this manner, the DIVC increases the range of AC input voltage to the LED driver while maintaining efficiency and stability of the LED based illumination system by reducing the variation of the voltage supplied to the dimming interface circuit over a larger range of AC input voltage.

    Abstract: A pixel-controlled LED light includes a plurality of LED modules and a controller. Each LED module includes at least one LED and a LED drive apparatus. The LED drive apparatus burns a counting ordinal number according to connection sequence thereof. The controller defines the counting ordinal number of the LED modules which need to be changed their light modes as a target value, and sequentially transmits light mode data whose number is greater than or equal to the target value to each of the LED modules. The LED drive apparatuses sequentially receive the light mode data for counting. If the sequence of the light mode data meets to the counting ordinal number of the LED drive apparatus, the LED drive apparatuses identify the light mode data that are met, and after identifying the light mode data, the LED drive apparatuses control the corresponding at least one LED.
