2.9 The arrangement of the iQ-LED and spectrometer
Arrange your iQ-LED devices so that the spectrometer can measure enough light of each iQ-LED and LED
channel. Ensure that the light from all of the LED
’s is correctly mixed when measuring with your spectrometer
and illuminating your target / DUT. If it is necessary, use diffusion material or extensions such as the Image
Engineering edgeBox or an integrating sphere to mix the light of all the LED
’s.
2.10 Starting software/usage of API
When using the iQ-LED system for the first time, you must set the integration time of your spectrometer to a
corresponding value. This procedure will ensure high performance in low light and will also help avoid any
clipping in the spectral measurement when all iQ-
LED’s are set to maximum. Please note that you must also
calibrate your system, please read the SW-control manual and follow the calibration steps.
When using your iQ-LED together with the API, please follow the instructions of the API manual.
2.11 A quick test of functionality without a PC
You easily can test all LED channels of your iQ-LED without using a PC. Just connect the power to your iQ-LED
and press the test button (picture flag 5) on the iQ-LED board. All 20 channels of your iQ-LED (and connected
iQ-
LED’s in a row) will light up separated one after the other, click by click. After 20 clicks on the test button, all
LED’s will be turned on. A final click will turn on the fan before turning off all of the LED’s. The intensity of the
LED’s when using the test mode is set to a much less intense level, but it is still advised to not look directly into
the
LED’s.
