LDR2/SQR Series
High-intensity light output, creating crisp vivid image

Direct light can be irradiated with focus on the center of the workpiece from any angle.

Flexible Circuit Boards
CCS has established a manufacturing method using
flexible circuit boards. Using a flexible board makes it
possible to improve product quality and increase
manufacturing speed.
Flexible Board

Significantly Suppressing
the Temperature Rise of LEDs
The LDR2 Series uses a special heat dissipating casing to
prevent heat from building up in the LEDs and increase the life
expectancy.

High-density Mounting
LEDs on Substrate

Using a flexible board makes it possible to adjust the outer
diameter, inner diameter, illumination angle, and other
characteristics to create an illumination system that is ideal for
the object being illuminated.

Illumination Structure of LDR2-90
The flexible board is formed to the desired shape and
a high-density LED array placed on the substrate. The light
is concentrated at the center of the illumination system.

With conventional construction, LED lights were not able to
efficiently dissipate heat due to the gap between the PCB
and aluminum housing. By employing a special heat
dissipating material between the PCB and the housing in
the new CCS construction, heat generated from the LEDs
can be more effectively conducted into the housing. This
new design suppresses the temperature rise of the LEDs,
providing stable images for a long period of time. (Refer to
page 103.)

Image comparisons utilizing
a polarizer
By decreasing the working distance
of the illuminator, the silver plated
sections of the lead frame become
much more clear.
Light used: LDR2 Series

LED glare in the top half of the image
distorts the image.
Using a polarizing plate and filter can
eliminate this glare, as shown in the
bottom half of the image.
