Burst Mode Operation

– 50% Burst Duty Cycle

– 2% Burst Duty Cycle
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 3 photo at right, careful
design consideration was given to controlling lamp start voltage
to softly start current flow. This eliminates current overshoot that
can result in premature cathode wear and reduce lamp life.
