Abstract:
1. A lighting system comprising: an alternating current (AC) input power source coupled with a power conditioning and control module, the power conditioning and control module adapted to receive an AC power signal from the AC input power source and to output a low voltage high frequency pulse width modulated (PWM) signal; a remote transmission cable coupled to the power conditioning and control module and to a remote transformer, the remote transmission cable adapted to carry the low voltage high frequency PWM signal, and the remote transformer adapted to convert the low voltage high frequency PWM signal to a high voltage high frequency PWM signal; a charge pump comprising one or more stages, the charge pump coupled to the remote transformer and adapted to receive the high voltage high frequency PWM signal and increase a voltage of the high voltage high frequency PWM signal with the one or more stages; a gas discharge tube coupled to the charge pump; and a controller coupled to the power conditioning and control module; wherein the controller is adapted to operate the gas discharge tube at two or more light intensity levels with the low voltage high frequency PWM signal produced by the power conditioning and control module.
