Vishay Intertechnology has released a ceramic-based, high-power UV LEDs with silicone lenses that boasts a wavelength in the 365nm range. Geared to deliver reliable, energy-saving replacement for mercury lamps, the Vishay Semiconductors VLMU3510-365-130 comes in a compact 3.45mm x 3.45mm surface-mount package for medical, industrial and printing applications, detailed the company.

The silicone lens of the VLMU3510-365-130 allows remarkably long lifetimes up to 25,000h, compared to the typical mercury lamp lifetime of 10,000h, Vishay stated. 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 two to 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 indium gallium nitride (InGaN) technology, the device features typical radiant power of 690mW at 500mA and 945mW at 700mA in a wavelength range between 362.5nm 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 ideal 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 UV LED are available with lead times of six to eight weeks.
