Rather than using the traditional dimming technique of
varying lamp current magnitude to adjust light output,
RangeMAX inverters use a fixed lamp current value with
a duty cycle control method.
The lamp current burst width can be modulated from
100% (continuous lamp current) down to a 2% duty cycle,
allowing the lamp to be dimmed to less than 1% of its
full brightness.
As can be seen in Trace 4 of Figure 8, careful design
consideration was given to controlling lamp start voltage
to softly start current flow. This eliminates current over-
shoot that can result in premature cathode wear and re-
duce lamp life.
