I'm working with an industrial camera that operates with a strobe illuminator that emits a high intensity flash, synchronized with the trigger for the camera shuttler, the standard configuration in this type of application where pictures are taken product per product at the conveyor belt, so far so good.

However, due to the semiconductors shortage, the strobe supplier will not be able to deliver on the scheduled date, and here we tested a cheap LED outdoor light fixture in continuous mode that performed excellently.

My fear is that somehow this incessant lighting ( unlike the pulsed trigger mode ) could quicly degenerate the sensor, but neither the camera datasheet nor the sensor chipset bring any reference to the allowed lighting limit.

The luminaire, which even being from a suspicious brand, at least brings relevant lighting information ( 24Kmlm@color temp. 6500K ), but the datasheet of the SONY CCD sensor of the camera ( ICX424AL ) makes no mention of the light intensity, either the range or the absolute maximum allowed value.

Does anyone have any tips as to whether this approach to continuous mode lighting would be an issue at all ?
