With higher output power, improved thermal characteristics and ready availability, UV LEDs are coming of age. As prices drop, wavelength ranges broaden and power output increases so new applications are being developed using UV LEDs.
YEG Opto, in Buckinghamshire, now offers a range of medium and high power emitters from SemiLED Optoelectronics Co Ltd, with power outputs from 70 to 360 mw radiometric power and wavelengths from 365 to 420 nm.
Utilising patented manufacturing technology (MvPLED) of die and copper alloy base, thermal management has been made easier. By keeping the junction temperature lower, the lifetime of UV LED emitters is extended.
As well as the curing of ink and adhesives, these UV LEDs can be used in a range of applications including life enhancing medical applications, machine vision for process monitoring and quality control, and as illuminators in several areas that benefit from lower operating voltages, improved portability and extended battery lifetime.
A division of the Young Electronics Group, the company offers a complete support programme for users or potential users of UV LEDs, and can advise from concept, through design and build of the UV engine, propose and supply optics, thermal management solutions (including water cooling) and a complete range of LED drivers.
