UV LED provides energy-saving replacement for mercury lamps

The VLMU5200-385-140 ceramic-based, high-power UV LED features a silicone lens and provides an energy-saving replacement for mercury lamps. It is offered in a 5.2 x 5.2 x 3.1-mm surface-mount package and targets medical, industrial, and printing applications. While mercury lamps require complex drive circuits and need two to 15 minutes to warm up, the UV-LED allows for the use of simple low-voltage circuitry and requires no warm-up period.

Built on InGaN technology, the UV LED device features typical radiant power of 2500 mW at 500 mA and 3600 mW at 700 mA in a wavelength range between 380 nm and 390 nm. It offers a wide emission angle of 140° and provides radiant intensity of 1054 mW/sr at 700 mA. 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.
