L.J. Star White Paper Illuminates Diffused Light for Process Vessels

Engineering analysis of diffused and undiffused light on stainless steel surfaces explains why LED lights may reveal scratches and what to do about it

L.J. Star Inc., a leading supplier of sight glass lighting, has released a new white paper that explains why the wrong kind of vessel lighting can make a stainless steel vessel appear scratched or contaminated when it’s really not.

Pharmaceutical, biotech, food, and some chemical manufacturing processes demand smooth, crevice-free surfaces that cannot harbor bacteria or other contaminants. As more operators switch to LED lights for illuminating the interiors of process vessels, many operators are alarmed by the sudden appearance of scratches seen on vessels surfaces.

The new white paper explains the science behind this phenomenon, and includes the results of an engineering study conducted by a process engineer, including a variety of technical drawings, equations and revealing photos.

An accurate view is essential for observing the characteristics of the process medium and for verifying process steps such as clean-in-place. This white paper discusses how to properly apply LED lighting to gain a brighter, clearer view of processes and avoid false positives during visual inspection.
