Image Engineering LG4 Uniform Light Box
INTRODUCTION
Important information: Read the manual carefully before using the device. Inappropriate utilization may cause damage to the device, to the DUT (device under test), and/or other components of your setup. Keep these instructions in a safe place and pass them on to any future user.
Conformity
We, Image Engineering GmbH & Co. KG, hereby declare that the LG4 corresponds to the essential requirements of the following EC directive:
- Electromagnetic Compatibility – 2014/30/EU
- Photobiological safety of lamps and lamp systems – IEC 62471:2009
Intended use
The LG4 is a high intensity illuminator for transparent charts based on LED technology. The device can be controlled over the integrated rotary knob and over the LG Software.
- Only suitable for indoor use.
- Place your system in a dry and constant tempered environment without any interfering light.
- The optimal ambient temperature range is 22 to 26 degrees Celsius. The maximum ambient temperature range is 18 to 28 degrees Celsius.
- The system has an internal temperature management system, if there is any error regarding the internal temperature the system automatically turns off to avoid any damage.
General safety information
Do not open the device without any instructions from the Image Engineering
support team or when connected to the power supply.
Eye safety
The LEDs used in the LG4 can be classified as belonging to the Exempt Group or
Risk Group 1 according to IEC 62471:2009.

Connecting the hardware
Connect the original 24 V DC power supply to the power socket (N) of the LG4.
Never use a third-party power supply.
CAN connection
If you have more than one LG4 and want to connect them over CAN (Controlled
Area Network), select the master LG4 and connect it to your PC.
Starting the system
The powerswitch (F) is located on the upper side of the control unit.
Power modes
The LG4 provides two intensity modes for the illumination
- NORM: 32 kHz PWM, variable duty cycle
- LOW: 32 kHz PWM, variable duty cycle approximately 1/10 of the NORM Mode power output
Switch between the power modes by pushing and holding the rotary knob (B)
PWM (Pulse Width Modulation)
The LG4 uses pulse width modulation (PWM) to control illumination levels. The
high frequency of 32 kHz allows a flicker-free image acquisition for most
cameras. The constant current has the benefit of a constant correlated color
temperature.
Setting the illumination level
Push and release the multifunctional rotary knob (B) to turn the illumination
on and off. Turn (B) to set the illumination level. Push and hold (B) to
switch between the LOW and NORM power modes.
Warm-up time
The intensity of continuous illumination in the LOW and NORM modes is not
actively stabilized. The efficiency of LEDs correlates to their temperature.
Depending on the selected illumination level and stability of the ambient
temperature, the LG4 regularly reaches a stable temperature after up to 10
minutes. The Illumination level will not fluctuate at a constant temperature.
ADDITIONAL INFORMATION
Maintenance
- Do not touch, scratch, or pollute the diffuser.
- If there is any dust on the diffuser, clean it with compressed air or an air blower.
Storage and Transport
Store and transport the LG4 only in a suitable package, providing sufficient
protection to the device. The LG3 flight case fits the LG4 and can be ordered
from Image Engineering.
Disposal Instructions
The LG4 must be adequately disposed of after the service life is over.
Electrical and electromechanical components are included in LG4. Observe your
national regulations and ensure that third parties cannot use LG4 after
disposing of it. Contact Image Engineering if assistance for disposal is
required.
