A ceramic-based UV LED, the VLMU1610-365-135 from Vishay provides typical radiant power of 18 mW at 20 mA and 50 mW at 60 mA over a wavelength range of 362.5 nm to 370 nm. The silicone lens of the device enables extremely long lifetimes of up to 25,000 hour, compared to typical mercury lamp lifetimes of 10,000 hours. by Susan Nordyk @ edn.com
Housed in a compact 1.6×1.6×1.4-mm surface-mount package, the environmentally friendly VLMU1610-365-135 is free of heavy metals and provides increased reliability with its shock resistance and immunity to degradation from frequent on/off switching. Aimed at medical, industrial, and printing applications, the LED allows the use of simple low-voltage circuitry and requires no warmup period. The VLMU1610-365-135 has a forward current of up to 60 mA and achieves an angle of half intensity ±67.5° at 20 mA.
