UV LED offers reliable mercury lamp replacement
Designed to provide a reliable, energy-saving replacement for mercury lamps, Vishay Intertechnology has announced a ceramic-based, high-power UV LED with silicone lens that features a wavelength in the 365nm range. The VLMU3510-365-130 delivers an exceptionally long lifetime in a compact 3.45x3.45mm surface-mount package for medical, industrial and printing applications.
The silicone lens of the VLMU3510-365-130 enables extremely long lifetimes up to 25,000h, compared to the typical mercury lamp lifetime of 10,000h. The environmentally friendly UV LED is free of heavy metals and provides increased reliability with its shock resistance and immunity to degradation from frequent on/off switching. While mercury lamps require complex drive circuits and need 2-15 minutes to warm up, the VLMU3510-365-130 allows for the use of simple low-voltage circuitry and requires no warm-up period.
Built on InGaN technology, the device features typical radiant power of 690mW at 500mA and 945mW at 700mA in a wavelength range between 362.5 and 370nm. The VLMU3510-365-130 offers an emission angle of 130° and radiant intensity of 315mW/sr at 700mA.
The LED's specifications make it suited for UV curing in nail salon, dental and poster printing applications; blood and counterfeit money detection; and photocatalytic purification. RoHS-compliant, halogen-free and Vishay Green, the VLMU3510-365-130 is compatible with reflow soldering processes and features a Moisture Sensitivity Level of 3 in accordance with J-STD-020.
Samples and production quantities of the VLMU3510-365-130 UV LED are available now, with lead times of six to eight weeks.
