摘要： Techniques are disclosed for measuring an amount of flicker produced by a light source. In one embodiment, a flicker measuring device includes a photo sensor to measure the amount of light produced by the light source, a dedicated processor to receive and process data from the photo sensor, a memory bus coupled to an analog-to-digital converter (ADC) and to a first memory, and a direct memory access (DMA) bus coupled to the ADC and to a second memory. In another embodiment, a flicker measuring system uses a light sensor, an associated circuit and a portable computing device (PCD), such as a smart phone, to measure an amount of flicker produced by a light source by sending an electrical signal from the light source and associated circuit via an audio output to an audio sub-system of the PCD, so that the PCD may calculate the flicker value.

摘要： Solid state lighting systems are disclosed for providing uniform brightness of LEDs serially connected in a string. In some embodiments, the LEDs can be powered directly from the mains such that no switch-mode power supply or the output storage elements associated therewith are needed. In some such cases, a linear regulator and switches can be used to control the current through the LEDs to provide uniform brightness. Other embodiments can be used with a switch-mode based driver topology and/or storage elements coupled in parallel with clusters of the LEDs. In any such cases, control logic (e.g., microcontroller or other suitable controller) can be used to control the switches accordingly to provide uniform brightness, and in some cases, to mitigate the implications of having no SMPS output storage element. In some embodiments, the switching pattern provided by the control logic is random, although other switching patterns can be used.

摘要： Techniques are disclosed for assessing the conditions of LEDs and power supplies of solid state lighting systems. The techniques can be used, for example, to measure the capacitance of an output capacitor C in a switch-mode power supply (SMPS), and to measure the condition of the LEDs being driven by that power supply. In some cases, this assessment can be implemented in a lighting controller that controls the lighting system, which may be configured to simultaneously determine C and the conditions of LEDs. In one example case, the techniques can be implemented, for instance, in a micro-controller operating the lighting system. A lighting system implementing the techniques can be periodically assessed so as to provide real-time diagnostic capability. Numerous example embodiments of SMPS LED lighting systems will be apparent in light of this disclosure.

摘要： A method of Light-based Communication (LCom) using camera frame-rate based light modulation is provided. The method includes receiving light having modulated light properties that vary at a first frequency from a LCom-enabled luminaire by an image capture device using a global shutter image capture process, comparing light properties received at the image capture device over sequential image capture instances, and determining, from the compared light properties, data encoded by the modulated light.

摘要： A controller dynamically identifies a switching frequency based power converter output load condition, input voltage, and/or temperature. The controller updates the operating switching frequency to the identified target switching frequency when the identified switching frequency is sufficiently different than a current operating switching frequency of the power converter. In this respect, switching frequency may be dynamically controlled to strike a balance between avoiding saturation of inductive elements and efficient operation of a power converter. A controller may also dynamically control switching frequency by having a thermo resistor incorporated into circuitry that determines switching frequency such that an increase in temperature beyond the threshold temperature directly causes a decrease in switching frequency.

摘要： Techniques for supplying auxiliary power to lighting driver circuitry are disclosed. An auxiliary power supply can be used, for example, to provide auxiliary power to a current source that drives an LED string. In some embodiments, the LED string is effectively used as a series resistor to charge a capacitor that provides the auxiliary voltage Vaux. As soon as the capacitor is charged to a given threshold, the LED string can be disconnected from the capacitor and the current through the LED string bypasses the auxiliary supply circuit. Thus, the current source provides a current through the LED string, which in turn may be selectively fed to the auxiliary power supply to provide auxiliary power back to the current source or to provide auxiliary power to other circuitry.

摘要： Techniques are provided for bi-directional communication between a power supply and one or more light engines (and/or other lighting system components) via the existing power lines so that no additional communication wires are needed. In particular, the power supply can transmit information by modulating its output (voltage or current) and the light engine (or other lighting componentry, such as a sensor) can communicate back by modulating how much power it draws from the power supply. Any suitable type of modulation scheme can be used, and a master-slave arrangement can be used to control the bi-directional communication if so desired, so as to avoid multiple devices communicating over the power line communication channel at the same time. Other embodiments allow a multiple simultaneous communications over the power line communication channel.

摘要： Techniques are disclosed for detecting stationary presence using IR sensor array. A number of IR images may be captured. Of the IR images captured by the IR sensor array certain pixels can be identified as causing false triggers. These pixels can be identified and filtered to be ignored. The non-filtered pixels of IR images may be averaged over various time intervals to calculate a number of average IR frames. The difference between these average IR frames provides a delta frame. A mask frame may be calculated as the summation of delta frames over time, and the value of the mask frame may be used to detect a stationary human presence even when no delta value is calculated. Alternatively, the mask frame may be used to calculate a background frame that represents the IR signature of stationary or cyclical objects within the scanned area that are not intended to trigger the presence detection system. A stationary presence may be determined by subtracting the background frame from a current average IR frame.
