  • Patent number: 10390241
    Abstract: Methods and system to determine the health of wireless mesh networks are provided. Each radio node of a wireless mesh network transmits Link Quantification Messages (LQMs) interPAN at maximum power to enable adjacent nodes to determine the Received Signal Strength Indication (RSSI) on the wireless link to that radio node. Each radio node also transmits LQMs at successively lower power levels. The adjacent nodes detect a power level at measurable packet error rate to determine a noise floor for the wireless link. An aggregator collects link quantification information from the radio nodes and forms an intercommunication matrix for the wireless network. The RSSI and power level at measurable packet error rate information is used to remove unreliable links from the intercommunication matrix. Nodes are ranked and the reliability and dependability of the nodes is calculated to show the network health.

  • Patent number: 10378715
    Abstract: A solid-state automotive vehicle headlamp includes a solid-state light source (SSLS), a clamshell reflector, and a reflector optic. The clamshell reflector includes a reflective surface defining a clamshell cavity with an open end facing a field to be illuminated. The reflector optic is defined by a portion of a spherical surface in surrounding relation to the SSLC. The reflector optic defines a light-transmissive window permitting a direct line-of-sight transmission of light generated by the SSLC to the reflective surface of the clamshell reflector. The reflector optic further includes a reflective region at least partially surrounding the light-transmissive window and configured to reflect light generated by the SSLC and directed at the reflector optic back towards the SSLC. The reflector optic redirects some of the light emitted by the SSLC through the light-transmissive window towards the clamshell reflector to create a more controlled beam pattern and increase the overall light output.

  • Patent number: 10381926
    Abstract: A digitally compensated hysteretic power supply with enhanced resolution is provided. Such a power supply includes a comparator that is used to compare a load current sense signal with an internal signal generated from a digital-to-analog converter (DAC). A compensation circuit at a DAC input operates to improve current accuracy beyond the given DAC resolution. The current sense signal is converted to its digital equivalent, which is fed to a proportional-integral (PI) compensation loop, which in turn generates a relatively precise high resolution DAC input value. The DAC uses the higher part of the DAC value. The lower part of the DAC value is treated as a duty cycle number, and the DAC output is toggled between two levels at this duty cycle. This toggling generates a current output signal having a value that is the average of the two toggled values.

  • Publication number: 20190246479
    Abstract: A luminaire includes a microcontroller and program logic that calculates the operational age of a light engine that includes a plurality of light emitting diodes connected in series. The program logic uses changes in transition voltage to calculate the operational age of a light engine. Changes in forward voltage across the light engine are used to detect sudden catastrophic failure of individual light emitting diodes. In response to the sudden catastrophic failure of one of the light emitting diodes, the program logic adjusts the power provided to the light engine based on the calculated operational age of the light engine. For example, the operational age of the light engine may be compared with a warrantied lifespan, and the power may be adjusted to increase the likelihood of compliance with the warranty.

  • Publication number: 20190238120
    Abstract: A solid state driver to adapt current ripple characteristics therein, at least partially based on operating characteristics of a solid state lighting device operated by the driver, is provided. The driver senses operating voltage, operating current, or a combination of operating voltage and operating current of a solid state lighting device. The driver stores pre-determined current ripple percentage settings in a data structure, for example, in a controller circuit. The driver selects and implements one of the pre-determined current ripple percentage settings based on one or more of the sensed operating characteristics of the solid state lighting device, to improve efficiency, to reduce the operating frequency, and/or to lower the operating temperature of one or more components of the driver.

  • Patent number: 10356861
    Abstract: A constant output current LED driver is disclosed. The driver is capable of operating with a wide range of input direct current (DC) voltage, and is configured with a full bridge inverter, an auxiliary circuit, and a voltage current converter. The full bridge inverter and auxiliary circuit collectively operate to provide a phase shift controller for the LED driver system. The LED driver operates under zero voltage switching (ZVS) for all switches in the LED driver circuit for all of the input voltage levels and for all of the output voltage levels. By maintaining ZVS in all conditions, the system can operate at very high frequency and be compact yet still achieve high power density. The resulting topology is applicable for a wide range of constant output current LED drivers. Switchable loads other than LEDs can also be driven.

  • Publication number: 20190208605
    Abstract: A network power distribution system includes a plurality of networked digitally controlled lighting devices and a network powered network controller. Each of the digitally controlled lighting devices includes a device driver that coupled to the network. The device driver is selectively transitionable between a first operating mode in which the device driver provides a first voltage and a first current to the network and a second operating mode where the driver does not provide a voltage or current to the network. The network controller autonomously determines a number of device drivers that, in the first operating mode, at least meet the current draw of the network controller. The network controller then transitions the determined number of device drivers to the first operating mode. The network controller monitors the device drivers for faults and autonomously swaps device drivers to maintain network power.
