Vishay's new high-power UV LED with silicone lens and ceramic substrate has a very long service life

Recently, Vishay announced the launch of a new VLMU35xx series ceramic substrate high-power UV LED device - VLMU3510-365-130, with silicone lens, wavelength in the 365nm range. Vishay Semiconductors VLMU3510-365-130 has reliable performance, energy saving, can replace traditional mercury lamps, has a very long service life, and uses a small size 3.45mm x 3.45mm surface mount package, which can be used in medical, industrial and printing fields.

The silicone lens of the VLMU3510-365-130 allows the device to have an amazing lifespan of 25,000 hours, much longer than the typical lifespan of 10,000 hours for mercury lamps. UV LEDs are environmentally friendly, contain no heavy metals, are more reliable, can withstand shock, and will not degrade even if they are frequently turned on and off. Mercury lamps require complex drive circuits and take 2 to 15 minutes to warm up, while the VLMU3510-365-130 uses a simple low-voltage circuit and has no warm-up time.

The devices released this time are manufactured using InGaN (Indium Gallium Nitride) technology, with typical radiant powers of 690mW and 945mW at 500mA and 700mA, and wavelengths between 362.5nm and 370nm. The VLMU3510-365-130 has an emission angle of 130° and a radiant intensity of 315mW/sr at 700mA.

The LED's performance specifications make it ideal for UV curing in nail, dental and poster printing, blood and counterfeit banknote detection, and photocatalytic purification. The VLMU3510-365-130 is RoHS-compliant and Vishay Green-compliant, halogen-free, reflow-compatible, and has a moisture sensitivity rating of Class 3 per J-STD-020.

Samples and production quantities of the new UV LED are available now, with lead times of six to eight weeks.
