An integrated lamp/lamp electronics unit includes a lamp having a first end with first end electrical terminals, and a second end with second end electrical terminals. An end cap having an interior section is placed into electrical connection with the first end electrical terminals at the first end of the lamp. Lamp electronics are configured to control operation of the lamp and are connected only to the second end electrical terminals. The lamp electronics are carried on a circuit board having a configuration substantially matching the second end of the lamp portion. The circuit board is placed within the interior of a lamp electronics end cap, and the end cap is attached in a permanent relationship to the second end of the lamp.

The present invention provides a lighting system powered by a system power source. The lighting system includes a ballast in operative connection with the system power source where the ballast is designed to generate a lamp input signal. A lamp input line is operatively connected to receive the lamp input signal. Further, a gas discharge lamp is in operative connection to the lamp input line configured to receive the lamp input signal. An amplitude modulation circuit is then placed in operative connection to the lamp input line, where the amplitude modulation circuit is configured to periodically modulate amplitudes of the lamp input signal prior to the lamp input signal being received by the gas discharge lamp. Operation of the amplitude modulation circuit results in a periodic amplitude modulation of the lamp input signal and eliminating visual striations otherwise occurring in the lamp.

A self-oscillating boost converter includes a resistor-starting network configured to start a charging of the boost converter. A resonant feedback circuit is designed to generate an oscillating signal following the starting of the circuit by the resistor-starting network. A complementary switching network has a pair of complementary common-source connected switches configured to receive the oscillation signal generated by the resonant feedback circuit. The oscillation signal determines a switching rate, or duty cycle, of the complementary pair of switches. A boost inductor is in operational connection with the complementary pair of switches. The switching rate of the complementary switching network acts to determine the boost voltage supplied to a load.

A ballast circuit including a power factor correction circuit with an alterable d. c. bus charging rate is provided. The power factor correction circuit selectively alters the d. c. bus charging rate such that, during a startup period for the ballast circuit, the charging rate is faster than during a steady-state period. The ballast circuit including a bridge rectifier, a power factor correction circuit, a bus capacitor, and at least one inverter. The power factor correction circuit including a power factor controller, a semiconductor switch operationally coupled to an output signal of the power factor controller, a selectively alterable impedance network operationally coupled to an output of the semiconductor switch and operationally coupled to an input signal of the power factor controller, and an impedance network control circuit operationally coupled to the impedance network to selectively alter the impedance network.

A ballast circuit is provided, comprising: a plurality of inverters, each inverter for powering a load; and a controller operationally coupled to a shutdown control signal of each inverter for selectively shutting down any combination of inverters. In another aspect, the controller is for selectively disabling any combination of inverters to effectively disconnect the load associated with each disabled inverter. The controller is for receiving communications from a control device, each communication a selection of 0%, “n-1” approximate percentages each associated with a ratio of “1” through “n-1” loads to “n” loads, where “n” is the total number of loads powered by the inverters of the ballast circuit and where the numerator for each ratio is an integer between “1” and “n-1,” inclusive, or 100% light from the combined loads powered by the inverters of the ballast circuit.

An inverter circuit for ballasting a gas discharge lamp having a delay circuit designed to delay regenerative control of the inverter switches until a d. c. bus has attained steady-state operating d. c. voltage. The inverter circuit includes a drive control circuit for inducing an a. c. load current. The inverter circuit includes first and second complementary switches serially connected between the bus and a reference bus. The switches are connected together at a common node through which the a. c. load current flows. A driving inductor is connected at one end to the common node and operatively connected at the remaining end to a control node. A load circuit includes a resonant inductor connected at one end to the common node, with the resonant inductor mutually coupled to the driving inductor. A resonant capacitor is serially connected between the remaining end of the resonant inductor and the reference bus. The gas discharge lamp is serially connected with a d. c.

Disclosed are a lamp igniter module and method of assembling a lamp igniter module. The lamp igniter module comprises a transformer carrier, a slide-in electrical connector, a pc board, and a housing. Assembly of the lamp igniter module is accomplished by initially inserting a transformer carrier assembly within the housing and subsequently installing a slide-in electrical connector which may or may not be attached to the pc board.
