Designing with L6585DE
29/41
Equation 31
L and C are chosen in order to fit the following constraints:
●
Preheating voltage has to be less than a value reported on lamp datasheet to avoid
early ignition.
Equation 32
●
In case of current controlled preheating, the Preheating current should be between two
values in order to obtain an effective preheating. These two values depend on the
preheating time, or, better, on the total energy delivered to the lamp during preheating.
Equation 33
●
Run frequency should be less than minimum ignition frequency. This frequency is the
frequency at which the voltage across the lamp reaches its maximum value (reported
on lamp datasheet).
