Output of the InGaN VLMU1610-365-135 is typically 18mW at 20mA and 50mW at 60mA within 362.5 to 370nm.
Life time is “up to 25,000h”, said the firm, which it attributes to the silicone lens, and compares to 10,000h which is says a typical mercury lamp lasts for.
Speaking of lenses, emission angle is 135°.
Why else is it better than mercury lamps?
Well, it doesn’t contain mercury, is more shock-resistant and is immune to degradation from frequent on/off switching, said Visay, doesn;t need a complex drive circuit and requires no warm-up period.
Applications are expected in nail salon UV curing, dentistry, poster printing, blood, counterfeit money detection and photocatalytic purification.
It can be reflow soldered and scores 3 in J-STD-020 moisture sensitivity.
“Samples and production quantities are available now, with lead times of six to eight weeks” said Vishay – make of that what you will.
