1 INTRODUCTION

Important information: Read the manual carefully before using this device.

Inappropriate utilization may cause damage to the device, to the DUT (device under test), and/or other

components of your setup.

Please keep these instructions in a safe place and pass them on to any future user.

1.1 Conformity

We, Image Engineering GmbH & Co. KG, hereby declare that the “iQ-Flatlight”corresponds to the essential

requirements of the following EC directive:

•Electromagnetic Compatibility - 2014/30/EU

•RoHS 2 - 2011/65/EU

•Low Voltage - 2014/35/EU

1.2 Intended use

The iQ-Flatlight is designed as a spectrally tunable source to illuminate large areas. It is based on iQ-LED

technology, includes a micro-spectrometer, and is controlled with the iQ-LED control software.

•Only suitable for indoor use.

•Place your system in a dry, constant tempered environment without interfering light.

•The optimal ambient temperature range is 22 to 26 degrees Celsius. The maximum ambient

temperature range is 18 to 28 degree Celsius.

•The optimal system temperature range, displayed in the software user interface, is between 35

and 50 degrees Celsius. The system has internal temperature management, if there is an error

regarding the internal temperature, you will get a warning message, and the system automatically

turns off to avoid any damage.

1.2.1 Departing from described setup

The following steps must be performed in the correct chronology to allow frictionless commissioning. Departing

from the chronology may lead to an incorrect working device.

1. Install the iQ-LED software

2. Connect iQ-Flatlight to power and via USB to the PC

3. Switch iQ-Flatlight on; the system drivers will be installed

4. After drivers are installed, restart the software

1.2.2 USB connection

Only an appropriate USB connection allows error-free operation of iQ-Flatlight. Use delivered USB cables. If you

need to extend the USB connection to longer distances, please check if powered hubs/repeaters are necessary.

1.3 General safety information

WARNING!

Some LEDs are emitting invisible light in the IR and UV near area.

•Do not look directly into the emitted light or look through the optical LED system.

•Do not look directly in the open sphere or light source when using high intensities or sequences

with low response time.

•Do not open the device without instructions from the Image Engineering support team or when

connected to the power supply.

2 GETTING STARTED

2.1 Scope of delivery

•Two iQ-Flatlight each with a spectrometer (calibration device) and Rolling Cart,

•2 x power cords,

•2 x USB cables

•Control software

•Calibration protocol

Optional equipment:

•iQ-Trigger: The iQ-Trigger is a mechanical finger that can press the release button within 25 ms. When

working with touchscreens, exchange the solid fingertip for a touch pen tip.

•Gossen Digipro F2: An exposure meter for high-precision incident light measurement. Perfect for

ensuring the illumination uniformity of reflective test charts.

•PRC Krochmann Radiolux 111: The Radiolux 111 is a high precision instrument for photometric

measurements.

2.2 Set-up homogeneity

To get a uniform illumination on your test chart, you must find the optimal position of your flatlights beside your

chart.

2.2.1 Height setting

•Start with the height setting. The iQ-Flatlights should be centered at the chart level. (see image below)

We recommend changing the height setting using two people.

•The first person holds the iQ-Flatlight (see image 1).

•The second person loosens the screws on the right and left on the inner side of the iQ-Flatlight (see

image 2).

•Loosen the screws of the center brace on the backside of the iQ-Flatlight to move it closer to the other

brace (see image 3).

•The first person can push the iQ-Flatlight up or down.

•If you have the correct height, tighten the screws and

•Tighten the screws of the brace.

Hold iQ-Flatlight (image 1) Second person loosens the screw (image 2)

Loosen the screws of the center brace on the backside of the iQ-

Flatlight (image 3).

2.2.2 Setup around chart

Start by placing your iQ-Flatlights as close as possible to your chart (~150 cm distance from the chart center to

the iQ-Flatlight) at an angle of 45 degrees, depending on your camera's optical axis. From there, begin

measuring the uniformity of illumination on your test chart and adjust the position of your flatlights to best suit

your test setup. We recommend using an exposure meter (see 2.1 optional equipment) to check the uniformity of

the light. Measure all four corners and the center of the chart. The values shouldn't deviate 1/10 f-stop from each

other.

2.3 Calculate and set compensation factor - chart plane

Complete the following procedure for each iQ-Flatlight with a luxmeter (see 2.1 optional equipment).

•Pull down the calibration device into the standby position.

•Open the spectrometer settings in the iQ-LED software and turn on the calibration light for the

compensation factor as described in the iQ-LED software manual.

•Measure the four corners and the center of the chart with a luxmeter and calculate the average value.

This value is your compensation factor for each iQ-Flatlight.

•Pull up the calibration device into the measuring position.

•Set the calculated compensation factor in the iQ-LED software. (see iQ-LED manual or iQ-LED quick

start guide).

•Conduct a new spectral calibration (see iQ-LED manual or iQ-LED quick start guide).

•The lux intensity in the software now corresponds to the intensity on the chart plane. You can now

generate new illuminants (see the iQ-LED manual or iQ-LED quick start guide).

Example: If you want 1000 lx on the chart level, set 500 lx for each iQ-Flatlight in the iQ-LED software.

3 OPERATING INSTRUCTIONS HARDWARE

3.1 Overview display and ports

•1 x USB port for software control

•1 x port for power adapter

•1 x trigger output

Use the control panel to set different light settings for the iQ-LEDs and the fluorescent tubes:

iQ-LED:

•With the “+” and “-“ buttons, you can switch between 44 saved illuminants

•Numerical display to show the storage of the illuminants

•With the play and stop button, you can start and stop a saved light sequence with different illuminants (it

is possible to save one sequence on the device)

•With the power button, you can turn on and off the light

•There are three pre-stored illuminants on your device (the intensity of each illuminant is shown in the

acceptance protocol of your device):

1: illuminant A (default illuminant)

2: illuminant D50

3: illuminant D75

Fluorescent (only for iQ-Flatlight with Fluorescent Tubes):

•When pressing the rotary knob, you can turn on or off the fluorescent tubes.

•While turning the rotary knob, you can set the intensity from low (0%) to high (100%).

Note: To store your generated illuminants or sequences on your device, please follow the the iQ-LED SW user

manual instructions.

Wiring examples for the trigger output:

Trigger OUT wiring examples

The default duration value for the trigger output is 500 ms. This value can be modified with the iQ-LED API.

A signal is sent out to the trigger output while changing the illuminates or the intensity of LED channels. It

can be used to synchronize your test setup. For example, with an iQ-Trigger (See 2.1 optional equipment).

3.2 Connecting the hardware

Connect the power cord to the power outlet on the side of your iQ-Flatlight. Connect the USB cable from the

Flatlight to your PC and turn on the Flatlight (the power switch is next to the power outlet). Then connect the

USB cable from the spectrometer calibration device to your Flatlight. The system will install the spectrometer and

iQ-LED driver on your PC (this will take a few seconds). You can check the installation in your hardware

manager:

4 OPERATING INSTRUCTIONS SOFTWARE

4.1 Requirements

•PC with Windows 7 (or higher) operating system

•One free USB port

4.2 Software installation

Install the iQ-LED control software before connecting the hardware. Follow the setup instructions from the iQ-

LED control software manual.

4.3 Starting the system

Start the iQ-LED software by clicking the ‘iQ-LED.exe’ or the iQ-LED icon on your desktop.

Follow the iQ-LED software manual to control your iQ-Flatlight.

NOTE

The iQ-LED devices can operate with high precision only when setup and calibration are performed

correctly. Consult the iQ-LEDsoftware manual for a comprehensive description, and read it carefully.

4.3.1 Spectrometer settings

The iQ-LED software (see iQ-LED software manual) automatically generates the best spectrometer settings for

your lighting conditions after pressing the “auto-detect” button. For special applications, it is also possible to set

the spectrometer settings manually. If you have further questions, please contact the Image Engineering support

team.
