Abstract:
1. An electronic control circuit for intelligently controlling a gas discharge lamp associated with an HVAC system comprising: a microcontroller having operatively coupled thereto; a memory including instructions executable by the microcontroller to process a plurality of dynamic lamp state signals and dynamically generate control signals in at least partial dependence on a plurality of pre-established control parameters to maintain the gas discharge lamp in a minimum operable state defined by the pre-established control parameters; an electronic ballast circuit configured to dynamically control a current flow through the gas discharge lamp in dependence on the dynamically generated control signals; and, wherein the microcontroller iteratively determines the minimum operable state of the gas discharge tube in at least partial dependence on a voltage excursion included as one of the plurality of dynamic lamp state signals.
