OPERATING INSTRUCTIONS FOR LED ILLUMINATION UNIT
DESCRIPTION
This new type of LED illumination device (Light Emitting Diode) has been
developed for stereomicroscopy illumination purposes in industrial and labor-
atory settings.
Please use the diagrams on the left-hand cover of this operating manual.
In purchasing this product, you have acquired a high-quality LED illumination
unit for all applications requiring intensive light with minimal heat generation.
LEDs are employed as the illuminant.
The following features are characteristic of this type of illumination:
T
Color temperature 5,000 K (daylight!)
T
Ripple and flicker free
T
Long LED lifetime
T
Quiet operation, free of vibration
T
Extremely compact design
T
Battery operation possible
The modular design of the LED illumination device in combination with the
T
Ringlight – provides homogeneous shadow-free illumination
T
Spot – provides directional illumination
T
Backlight – provides homogeneous illumination which passes the object
The illumination system consists of:
T
(Desktop) power-supply
T
Control unit and
T
LED unit (1 ringlight 66/40 or 1 or 2 spots or backlight or ringlight 38/20)
The
power-supply
(C) voltage range extends from 100–240 V and features a
3-pin plug connector.
The compact
control unit
(D) has an On/Off switch (1), a continuously adjust-
able brightness control (2) with a „turbo range“ and two connector plugs (4) for
connecting the LED illumination units.
A 24 V battery or an accumulator can be attached to the control unit via a
special cable by means of the hollow plug connector (3).
The
LED ringlight
(40 LEDs) (A) allows surfaces to be illuminated exceptionally
brightly and homogeneously and fits all microscopes with an objective diameter
of 66 mm. Adapters are available for use with other microscopes. The ringlight
is attached by means of a spring and screw, thereby protecting the objective.
The
LED spot
(19 LEDs) (B) can be attached directly to the microscope using
a goose neck (6) or can be positioned as required using the goose neck and a
base plate.
A wide range of accessories allows this LED illumination to be used for many
purposes.
The
LED backlight
(20 LEDs) (E) can be used instead of the microscope’s object
holder to illuminate transparent objects from the bottom.
Please read all the operating instructions before operating the LED illumination unit!

(*) LEDs are suitable for use at temperatures up to 40 °C. However, increasing temperature and humidity results in a reduction in lifetime. For optimal use, the ambient temperature should be 25 °C (or
lower) and the relative humidity 50 % (or lower).
CE Mark of conformity: Certifies that the control unit conforms to the EMC directive 89/336/EEC
