Low-angle Ring Lights
LDR2-LA/LDR-LA-1 Series
Ideal for edge detection and highlighting scratches on glossy surfaces
Low-angle illumination is ideally suited for edge detection and for emphasizing incused characters or
scratches on metal surfaces.
Low-angle illumination can be used to highlight
characteristic features of workpieces
The LDR-LA-1 is an ultra-low-angle illumination system with an ultra-thin
design of just 10 mm. The thin design means that only minimal space is
required for installation. At a working distance from the light of 5 to 10
mm, the system can emphasize edges and height variations when taking
photographs.

Aluminum Body
Aluminum Body Also Acts as a
Highly Effective Heat Sink
Aluminum is used as the outer material for nearly all of the
image processing LEDs systems produced by CCS. Aluminum
is a good heat conductor and
acts as a heat sink to keep the
internal temperature of the
illumination system from rising.
Heat can be a major problem
for LED illumination systems,
decreasing light intensity and
reducing the life of the LEDs.
The use of an aluminum body
helps minimize these problems.
Illumination structure of LDR2-132-LA
A flexible circuit board is fixed at the desired
angle to illuminate the workpiece from a low
angle.

Using a Diffusion Ring or Diffusion Panel suppresses
glare and LED reflections that may be a problem when
capturing images of glossy workpieces.

Existing RD-type Red Lights will be discontinued at the April 15, 2013. RD2-type
Red Lights is recommended as replacement.
The RD-type and RD2-type Lights have different input voltages. Always use a
24-VDC Control Unit with RD2-type Lights. For a comparison between the RD-type
and RD2-type Lights, refer to page 1.
