UV LED has silicone lens for energy-saving lamps
Mid-power UV LEDs in the 365 nm wavelength range from Vishay Semiconductors now includes the VLMU1610-365-135. It features a silicone lens in a compact 1.6 x 1.6 x 1.4mm surface-mount package. It is designed as a reliable, energy-saving replacement for mercury lamps and is claimed to offer long lifetime for medical, industrial, and printing applications.
The silicone lens enables 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 is claimed to provide increased reliability with its shock resistance and immunity to degradation from frequent on/off switching. The LED allows for the use of simple low-voltage circuitry and requires no warm-up period.
Built on InGaN (indium gallium nitride) technology, the device features typical radiant power of 18mW at 20mA and 50mW at 60mA in a wavelength range between 362.5 and 370nm. Emission angle is 135°.
The LED’s specifications suit UV curing in blood and counterfeit money detection, photocatalytic purification, nail salon, dental, and poster printing applications, says the company.
They are RoHS-compliant and halogen-free and is compatible with reflow soldering processes. Moisture Sensitivity Level 3 is in accordance with J-STD-020.
