EasyLED - Operating Instructions
8/13
Ringlight Plus
Attachment to the microscope objective, the power connection, on/off switching and
brightness adjustment do not differ from the basic version. See the description in the
“Ringlight” section above.
Additional functions:
The EasyLED Ringlight Plus has an additional function for controlling segments, which
makes it possible to regulate the LED ring as individual segments, each with 12 LEDs, using
a “jog dial” switch (6). This control lets the user achieve full-circle, semi-circle, quarter-circle
and two quarter-circle illumination as well as rotations in both directions.
Setting up segment mode:
With each press of the “jog dial” switch (6) the illumination switches from full-circle mode to
semi-circle mode to quarter-circle mode to two quarter-circle mode and back to full-circle
mode. When first switched on, the ringlight always starts in full-circle mode.
