Abstract: A high power lighting fixture which includes a first multiple of first light emitting diodes (LEDs) mounted and series connected to form a first serial string of LEDs on a first circuit board. A second multiple of second light emitting diodes (LEDs) mounted and series connected to form a second serial string of LEDs on a second circuit board. Mating circuit board connectors are mounted on the first and second circuit boards. The first and second LEDs, the number of first and second LEDs and the current supplied when operating the first and second LEDs are selected so that the lighting fixture is operable at a minimum electrical power rating of 100 Watts. A control signal is received which determines current division between the first and second LEDs.

Abstract: Computerized methods are provided herein for remotely configuring a driver operable to power an illumination system, over a wide area network. A configuration request is received by a configuration server over the wide area network to configure the driver. The configuration request is from a configuration client operatively attached over the wide area network to the configuration server. The driver is configured by transmitting instructions from the configuration server to the configuration client to produce a driver configuration. A data base attached to the configuration server is updated based on the driver configuration.

Abstract: A method for using an electronic ballast circuit configured to operate a high intensity discharge (HID) lamp. Multiple light emitting diodes (LEDs) are attached to the current output of the electronic ballast circuit, and current is driven from the current output to light said LEDs. Optionally, prior to driving current through the LEDs, the impedance of the current output is sensed; and the current is driven through the LEDs to light the LEDs upon detection of an impedance significantly lower than an impedance characteristic of the HID lamp. Ignition appropriate to ignite the high intensity discharge is not performed when LEDS are attached to the current output. Alternatively, a signal is provided to disconnect the LEDs during a high voltage output for ignition of the high intensity discharge (HID) lamp.

Abstract: A ballast circuit adapted for converting an input alternating current (AC) mains power received at input terminals to an output alternating current (AC) to supply a load, e.g. a gas discharge lamp. The output terminals of the ballast connect to the load in parallel with another ballast circuit. The ballast circuit is configured to supply the output AC current to the load in parallel with an AC current output of the other ballast circuit. A synchronization module attached at the output is adapted for synchronizing the output alternating current (AC) of the ballast circuit with the AC current output of the other ballast circuit. The synchronization module is configured to synchronize phase of the output alternating current with phase of the AC current output of the other ballast circuit.

Abstract: A method for igniting and operating a high intensity discharge (HID) lamp using an electronic ballast controlled by a ballast microcontroller. An ignition circuit including a parallel capacitive circuit is connected in parallel to the HID lamp. The ignition circuit being resonant at an ignition resonance frequency. An ignition voltage is provided to the HID lamp at the ignition resonance frequency, thereby initiating ignition of the HID lamp. Upon sensing the ignition, the HID lamp is powered at an operation frequency. Both the ignition resonance frequency and the operation frequency are in a high frequency range above fifty kilohertz. The ignition voltage preferably does not include a significant direct current offset The current flowing through the HID lamp is substantially continuous during the transition from providing ignition voltage during the ignition to powering the HID lamp at the operation frequency.

Abstract: A ballast for operating a high intensity discharge (HID) lamp includes a mechanism which provides electrical power to the HID lamp and a frequency-selecting mechanism which selects a frequency of the electrical power based on an atomic component present in the HID lamp. Preferably, the frequency is selected within a range between two hundred kilohertz and nine hundred kilohertz. Preferably, the frequency is near two hundred kilohertz and the operation enhances radiant efficiency at blue-green wavelengths due to excitation states of: scandium, indium, thallium and rare earth elements. Preferably, when the operation frequency is near seven hundred kilohertz, the operation enhances radiant efficiency at red wavelengths due to excitation states of atomic components selected from alkali metals.
