Characterizing the Efficiency of UV LED Curing
This paper examines the effects of some key operating parameters of UV sources on the curing of various UV inks, coatings and adhesives. The effects of peak UV wavelength and peak intensity are quantitatively evaluated using FT-IR. The data are helpful in guiding both formulators, raw material suppliers and end users to better understand the impact of the UV sources, especially UV LED sources, ...
متن کاملUV-LED Curing Efficiency of Wood Coatings
Ultraviolet light emitting diodes (UV-LEDs) have attracted great interest in recent years. They can be used to polymerize coatings, such as those used for prefinished wood flooring. In this project, two lamps were compared for their suitability to be used on a wood flooring finishing line: a UV-microwave and a UV-LED lamp. Low heat emission was found for the UV-LED lamp compared to the UV-micro...
متن کاملResearch on a High-Efficiency LED Driving Circuit Based on Buck Topology
A high efficiency LED (Light Emitting Diode) driver based on Buck converter, which could operate under a wide AC input voltage range (85 V 265 V) and drive a series of high power LEDs, is presented in this paper. The operation principles, power loss factors of the LED driver in this study are analyzed and discussed in detail and some effective ways to improve efficiency are proposed through sys...
متن کاملSupporting southern-led research: implications for North-South research partnerships.
BACKGROUND Global health research partnerships are commonly led by Northern investigators who come from resource-rich research environments, while Southern partners participate with a paucity of research skills and resources. This power asymmetry within North-South research partnerships may further exacerbate the unequal distribution of benefits from the research process. METHODS This study i...
متن کاملPriority setting in research: user led mental health research
PLAIN ENGLISH SUMMARY Involving people in health research is increasingly recognised as being important to make sure that research is focused more on the needs of people who use health services. At present, ideas about what should be researched most often comes from researchers and/or health professionals like doctors and nurses rather than people with a lived experience of mental illness. In t...
