By Jennifer Heathcote, Eminence UV The list of viable UV LED applications continues to grow – as does the number of system suppliers, formulators and OEM machine builders supporting those applications. This ongoing increase in activity bodes well for the general market direction of UV LED technology. As a result, those who aren’t already investigating its suitability for their … [Read more...] about State of UV LED Curing Applications

Q. Why Measure UV LEDs?
I was drafted (volunteered) to take this column over from Dick Stowe when he finally convinced the editors of UV+EB Technology that he wanted to slow down a little. We owe Dick a big thanks for the work he has done to educate and help users understand UV technology, measurement and process control. He has done this not only with this column but over a long career, and I have … [Read more...] about Q. Why Measure UV LEDs?
Critical Roles for Germicidal LEDs in Health Care Delivery Facilities
By Peter E. Gordon Bolb Corporation Infectious diseases are caused by various pathogens: vegetated bacteria, bacterial spores, virions and fungi. Once transferred upon or introduced into a susceptible patient’s body, these pathogens, some of which are now antibiotic resistant, replicate and can cause an infection and illness, sometimes resulting in great discomfort and even … [Read more...] about Critical Roles for Germicidal LEDs in Health Care Delivery Facilities
Q. Why is there no ‘standard unit’ similar to lighting products for the radiant output of UV lamps?
A. The visible portion of the output (luminous flux) of lamps used for illumination is expressed in lumens, a measure of the total quantity of visible light emitted by a source. This is possible because the output is measured only in the wavelength response range of the human eye. This response is defined as the photopic luminosity function (Figure 1). Illuminance is the … [Read more...] about Q. Why is there no ‘standard unit’ similar to lighting products for the radiant output of UV lamps?
