This graph (figure 3) shows the increase of the trigger current
when the device is expected to operate at an ambient tempera-
ture below 25°C. Multiply the normalized I

sine wave. Phase control may be accomplished by an AC line
zero cross detector and a variable pulse delay generator which
is synchronized to the zero cross detector. The same task can
be accomplished by a microprocessor which is synchronized
to the AC zero crossing. The phase controlled trigger current
may be a very short pulse which saves energy delivered to the
input LED. LED trigger pulse currents shorter than 100 µs must
have an increased amplitude as shown on Figure 4. This graph
shows the dependency of the trigger current I
