Edge Mount Back Lights
Surface Mount Back Lights
■High-intensity thin backlight
Backlight with SMD type LED mounted.
Also, it is densely mounted with chip LEDs, and thus even
illumination is possible.It is also suitable for permeable lighting.
●Features
・Lighting with red chip LEDs mounted on the surface producing even light
via a diffusion plate
・Can be used to judge the shape from the silhouette by illuminating from
the back of an object
●Applications
■Low-heat-generating Power-saving Thin Backlight.
・Inspection of dimension and shape of electronic parts
・Inspection of dimension and shape of lead frame
・Lighting inspection of liquid crystal panel
・IC lead inspection
・Recognition of alignment sign of glass board and 2D
The LEDs illuminate from around a light guide on the whole
surface, and thus the LED elements are not reflected and the
illumination is even. The intensity is lower than bar lights and
surface mount backlights, but this slim-type light can be used in
narrow spaces. However, if the light area grows wider, light cannot
reach the center and thus illuminance is decreased compared with
the surrounding area.
●Features
・Slim-type Lighting with LEDs mounted around the light guide to brighten it
・Even illumination on the surface allowing only the LED mounted outer
circumference to be brightened
●Applications

Intensity control by Pulse Width Modulation
Advantages
Even illuminance due to less affect from Vf fluctuation of LED elements.
Disadvantages
As the shutter speed of the camera increases, the image brightness fluctuates.
(Fluctuation rate at shutter speed 1/4000 second: 60kHz: 6.7%, 78.125kHz: 5.1%)
This is because the start of imaging on the camera side and the pulse on the power supply side are not synchronized.
Output wattage of power supply
Please choose a power supply in which the total consumption power of lights connected to each channel does not exceed
the volume of the power supply.
(Example) When the lights of 15W and 6W are connected to a power supply of channel 2, 15W+6W=21W and thus a power supply of 30W should be chosen.
Time lag when controlling light
The LED is a semiconductor, which has a high power-generation capability.
Turning the light on and off does not shorten its life.
Thus we recommend using the product with the ON/OFF control function for long use with minimum heat generation.

Features of LED lights
A fluorescent lamp and Halogen have wide wavelength distribution,
but LED includes a specific emission of light wavelength in each.
When selecting a wavelength, please consider the points below:
■ High efficiency, low power consumption
■ Low total running cost
■ Very fast response time
■ Durable against switching
Elements required for image processing Lighting:
3. Stable illumination intensity
A large change in illumination intensity over time or due to
the surrounding environment can cause inspection
accuracy to decrease.
Even with a low initial cost, light which needs frequent
maintenance will increase long-term costs.
Installing long lasting and stable illumination reduces the
total running cost.
2. Even lighting
Wavelength (nm)
Even illumination intensity in the imaging area is
required when extracting the inspection item by LED light.
Unevenness of illumination intensity prevents correct
reflection of the object's surface condition and causes
unstable inspection.

Halogen Spectral Distribution
Visible light is light that can be seen by human eyes. Visible light generally
has a wavelength of between 380nm and 780nm. Light with a wavelength
higher than 780nm is infrared and light with a wavelength lower than 380nm
is ultraviolet.
The human eye is most sensitive to green light with a wavelength of 555nm.
Sensitivity decreases if the wavelength increases or decreases. The sensitivity
curve when this 555nm is counted as 1 is called the Spectral Luminous
Efficiency. Measurements of brightness such as lux and cd/m2 are coefficients
of this Spectral Luminous Efficiency.
The spectral sensitivity of a camera does not necessarily have the same
distribution as the Spectral Luminous Efficiency. The sensitivity of some
cameras is set to match infrared or ultraviolet ranges. When setting Lighting,
please check that the light distribution matches the camera you are using.
LED
HALOGEN
Wavelength (nm)
The comparative scattering rate for each wavelength is shown when the red
scattering rate is counted as 1. The scattering rate increases as the wavelength
gets shorter.
When using a wavelength with a high scattering rate, it becomes easier to
observe scattering light from the object surface. However, please note that
when using a wavelength shorter than green, the camera's sensitivity may
decrease.
When using a long wavelength, permeability increases. Infrared lighting, in
particular, is effective for inspecting permeability.
Relative Strength (%)
For a stable image processing inspection, the imags to be
inspected must be as clear as possible.
The LED lights create an image with a high SN rate, by
selecting the optimal shape and wavelength for the target
object, which leads to high inspection quality.

Points when setting the Lighting
The Visual Field of Coaxial Lighting
When setting the Lighting it is necessary to consider several factors.
Even when using the same Lighting, if the set height is different the captured
images are completely different. Also, if the Lighting wavelength (color) is
different, the images change. When setting Lighting, please consider the
points below:
Coaxial Lighting is a type of Lighting in which the surface emitting part of the
LED emits light along the same axis as the camera lens, via a half-mirror. The
effective visual field of coaxial lighting is dependent upon the distance
between the camera and object (OD), the distance between the Lighting and
object (LOD), and the size of the light emitting surface. If the OD increases,
the visual field grows, but if the LOD increases, the visual field shrinks. The
method of calculating the effective visual field is shown below. It is necessary
to keep the object within the effective visual field, especially for objects with a
high reflectance. This effective visual field is calculated based on the size of
the light emitting surface. It is recommended that you set a sufficient visual
field, taking into consideration the lower luminance in the surrounding area.
Testing Conditions
Additive Primary Colors
By combining the light of red, green and blue (additive primary colors) you
can create other colors. Green(G) and blue(B) make Cyan(C), B and red(R)
make Magenta(M), and R and G make yellow(Y). By combining R, G, and B
lights of the same strength, white(W) is created. Combining colors in this way
is called additive color mixing.
Colors can also be created by absorbing parts of light. C absorbs R, M
absorbs G, and Y absorbs B. C, M, and Y absorb all of the light, and black(K)
is created. Combining colors in this way is called subtractive color mixing
and CMY are called subtractive primary colors.
White Lighting
Subtractive Primary Colors
The color pattern using CMY is shown below. Also, color images using white,
red, green, and blue and the monochrome image are shown. The contrast
varies depending on the color of the light. When recognizing the object during
image processing, it is important that there is sufficient contrast. During
image processing, please select a light color where there is a large contrast
between the object color and background color, referring to the color patterns
below.

How to Use and Maintain LED Lighting
To get the best performance from LED Lighting:
Virtual light
emitting surface
1. Please avoid using LED lights in a high-temperature environment.
Doing so may lower the illuminance and facilitate deteriortion.
Red Lighting
Green Lighting
Blue Lighting
If the LED element becomes heated, illuminance is reduced and general
performance deteriorates. The half-life of the illuminance of an LED
element is said to be about 20,000 hours (Typ.), but if the element is
continuously used in a high-temperature environment, its performance may
deteriorate quicker.

2. To prevent illuminance reduction and performance deterioration
due to the generation of heat:
Color Image
●Improve the heat dissipation of the LEDs.
・ Mount the Lighting on a bracket with good heat conductivity.
・ Install a ventilating device.
・ Install a fan.
We recommend creating a cool environment which allows easy heat
dissipation.

● Turn the Lighting on only when imaging.
The performance of LED Lighting is not affected much by switching the
power on and off.
To extend the LED's life, utilize the on/off function controlled by external
signals powered by this company, and only turn the LED on when
necessary.
Monochrome
Image
Differences in observation light due to the relative
positions of the Lighting, camera and object.
Depending on the type of object, positional differences of the Lighting,
camera and object can affect the image.
Each situation is described below:

(bright field)
Observing scatter reflection light
(dark field)
Lighting
Lighting
Camera
Observing specular transmission light
(bright field)
Lighting
Observing scatter transmission light
(dark field)
● Use lights at low volumes.
If the light is set to a low volume, the current flowing into the LED
decreases and the heat generation is suppressed.
To choose Lighting with sufficient brightness, evaluate each Lighting when
the camera's aperture is as open as possible.
If using the Lighting continuously, we recommend a volume of 50%.
(Even if performance deteriorates and illuminance is reduced, normal use
can be restored by increasing the volume.)
Lighting
3. Use the Lighting as close as possible to the target object.
Object
Transparent glass
Object
Since the element itself is small, LEDs can manufactured as small and
lightweight lights. The illumninance is inversely proportionate to the square
of the distance, and thus using the Lighting at a close distance can increase
the light intensity greatly.
