"CONTROL EQUIPMENT FOR INITIALIZING A TOTAL VOLTAGE LOAD DEVICE AND FOR CONTINUOUS OPERATION AT A REDUCED VOLTAGE WITHOUT LOSS OF CONTINUITY BETWEEN THE VOLTAGE REPRODUCTION METHOD OF A VOLTAGE INITIALIZATION OF A FULL VOLTAGE HID LAMP OPERATING VOLTAGE AND REDUCTION FOR CONTINUOUS OPERATION WITH REDUCED POWER CONSUMPTION WITHOUT CONTINUITY INTERRUPTION BETWEEN THE HID LAMP LINE AND MODULAR HIGH-DUTHING DUTY PLUG CONTROL UNIT. It features improved equipment and a method for controlling discharge light, such as high intensity discharge (HID) light, performs full light voltage initialization and continuous light operation at a reduced voltage after a selected and variable startup phase or at breaks; the equipment includes an autotransformer having primary and secondary ventilation; primary ventilation is always in series with the load, but may be decreased to match the total line voltage of the line to the load; when primary ventilation is not decreased, secondary ventilation is connected to the load as well, so that the reduced voltage is supplied to the load; A thermal analogue device simulates the constant heating time of the HID light unit, so that the reduction in operating voltage to the HID light unit is effected only after this light unit has reached a temperature sufficiently high to sustain operation and reduced operating voltage.
