Life was easier when UV lamps stretched across a web or flat conveyor, and all we had to worry about was width and number of rows. But, as we moved into 3-D processing, we find lamps located all over the curing zone. In fixed-lamp 3-D configurations, each lamp has its own optimized position. Setting lamps in a large 3-D installation falls somewhere between science and art.
Have you ever tried to describe the orientation of a UV lamp – or several lamps – in a 3-D configuration? Have you watched an otherwise conservative engineer waving his hands and arms, often with the assistance of pens (to represent bulbs) and file cards (curved, to represent reflectors), trying to communicate the orientation of a lamp in space? What about changing the position of a lamp? Does it drive you nuts to hear the description of “Just rotate the lamp a little.” “Rotate? - What does THAT mean?” “You know – tilt it.”
This isn’t a new problem – how to orient something in space. There is a language that is clear and one that we can adapt easily to 3-D UV lamp orientation. It’s used all the time in flight and aerospace situations. There are two parts: attitude and position.
