The LC6 now comes loaded with 3 major new functions for better stabilized optical curing
Memory Step
for 9 types 7-step programs
Power saving mode available
Program the irradiation intensity and irradiation time to any level you want! Free-
ly set the UV irradiation conditions to match the component you want to bond.
The LIGHTNINGCURE LC6 lets you store nine types of 7-step programs in the
memory, so optimal irradiation conditions matching the component for bonding
can be set just by changing the program number. This holds true even when
multiple bonding components are flowing in the same production process or
when shifting to different production lines.
The LC6 is especially ideal for components that must be fixed in place with
high precision. The mounting positions of these components often deviate due
to stress warping and contraction in the adhesive that causes positional shifts.
Using the LC6 gives better production stability and higher product yield espe-
cially for components demanding high position precision.
Optical power monitor with optical feedback
(option: sold separately)
Selectable power-saving mode cuts power con-
sumption by 10 % compared to normal operating
mode. This really helps save power when using mul-
tiple units!
This operating switch is on the surface of rear panel.
An optical power monitor C8952 with optical feedback can be added
as a useful option for maintaining constant irradiation power. The
built-in sensor constantly monitors the light intensity that usually va-
ries with operating time, and the sensor output is feedback to con-
trol the iris so the light intensity is always maintained at a preset
constant level.
The irradiation power (reference value) when using the standard
light guide is shown in a digital display (in watts) on an LCD panel.
This eliminates mistakes that occur due to using the wrong condi-
tions or human errors during measurement.
This also means finer control on fully automated lines.

FEATURES & FUNCTIONS
Clever layout allows a compact body
Weight has been also reduced
6.5 kg making it 1.5 kg lighter
than previous other models. Su-
perior product features have all
been condensed into this new,
compact body.
Anybody can use it! One-touch replacement!
Lamp is replaceable in less than 30 seconds!
Just insert the lamp to replace it. No wiring to worry about. This is
so easy you can do it with one hand.
Lamp is the cassette type with a preset optical axis so no trouble-
some optical alignment is needed after replacement.
Use lamps from other models
We also offer the L8388 (LC5 series) and L8878 (LC6 series) UV
spot light sources that can use lamps compatible with the earlier
models of Hamamatsu UV spot light sources.
Light source model changes go smoothly since you don't have to
keep replacement lamps for many different models on hand.

Light intensity adjustable anywhere within 0 to 100%!
Selectable positions of light guide port
Full line-up of external control equipment
(D-sub connector: standard feature, terminal block: option [sold separately])
An electric diaphragm mechanism allows a digital display of the rel-
ative light output from 0 to 100 % on the LCD panel. Unlike conven-
tional analog scales, this means highly precise light irradiation. Light
output also can be controlled from an external device, so meeting
various kinds of measurement conditions is now even easier.
A front port type and a rear port type are available. The front port
type allows lamp replacement from the operation panel side. This
helps hold limits on equipment movement and installation location
to a minimum.
Select the light guide port position that best matches the compo-
nent for bonding and its mounting position.
Left: Front light guide port type, Right: Rear light guide port type
Turning the lamp on and off and opening-
closing of the shutter can be controlled by
input of external signals. An alarm signal
output is also provided. This means ideal
usage conditions on semi or fully automated
production lines.
Restores operation in about 10 seconds after power outages of a
second or less.
Conventional products take at least a few minutes to start up again
after a power shutdown, so you can see this function drastically
shrinks down-time due to power outages.
This function is especially convenient in places where the supply of
power is intermittent or unstable.
Our 200 W lamps have high intensity equal to lamps in the 250 W
class. Light sources using our 200 W lamps also have less power
consumption than those using 250 W lamps.
Power consumption is the lowest in its class (280 VA Typ.). This
means using multiple UV light source units at production facilities
will yield tremendous energy saving benefits.
Instantaneous power-outage response program
Great energy saving benefits
Internal power supply automatically
switches to a 100 or 200 V input.
There is no problem when shifting the
operating location in world-wide.

GUV intensity distribution
GStructural View
The LC5 yields an extremely strong spectral distribution in the UV
range most effective for UV curing. UV intensity distribution is de-
pendent on the distance from the light guide output end to the target
surface to be irradiated, as well as on the type of light guide used.
The greater the distance from the light guide output end to the tar-
get surface, the more the maximum UV intensity drops and the
more the light beam expands (see below).

Long service life

UV intensity generally declines with lamp operating time. Hamamatsu
has drastically improved these drops in light intensity by using a
mercury-xenon lamp whose electrodes suffer almost no wear and
an improved optical system.

Highly durable & high response shutter
The stepping motor used for the shutter in the LC5 has a service
life 5 times longer than conventional rotary solenoids. Along with
eliminating shutter troubles, the once noisy sound of shutter open-
ing and closing can now hardly be heard. This makes the LC5 ideal
for 24-hour continuous operation.
The quick-response mechanism allows opening and closing of the
shutter at very short intervals.
No optical axis alignment
Uses a highly stable mercury-xenon lamp* developed expressly for
analysis and measurement applications. There is almost no wear
on the electrodes and no positional shift of the arc point.
Absolutely no optical axis alignment is needed, even during lamp
replacement or during lamp use.
GElectrode wear
Before use
After 3000 hours of use
The LC5 combines a mercury-xenon lamp having high-intensity
UV line spectra with an elliptical reflector (UV cold mirror) having
reflectivity higher than 90% in the UV range and a quartz light
guide with excellent UV transmittance.
The lamp can be operated in a horizontal position, so the optical
system has less light loss compared to lamps operated in an up-
right position, allowing the UV light to input efficiently to the light
guide. The elliptical reflector efficiently reflects only the UV light,
and lets heat rays and visible light pass through to prevent adverse
effects from heat on the irradiated point.
High efficiency optical system - no heat problems
Selectable wavelength
The LC5 allows you to select the wavelength range you need. The
"-01" type suitable for wavelengths around 365 nm and the "-02"
type enhanced for 250 nm band are provided. Select the light source
that matches the adhesive agent you use.
These can also be combined with UV-transmitting filters that cut visible
and infrared light, and minimize heat effects on the irradiated point.
A visible light type is also available (radiant wavelength range from
400 nm to 700 nm).
