It was reported that the United States Vishay Semiconductors (Vishay Intertechnology) introduced a new UV LED --VLMU5200-385-140 ceramic substrate with the silicone lens. Vishay VLMU5200-385-140 is designed to provide a reliable, energy-efficient alternative mercury lamp. It has a very long life and is available in 5.2mm x 5.2mm x 3.1mm surface mount packages for medical, industrial and printing applications.
The VLMU5200-385-140's silicone lens delivers an extremely long life compared to typical mercury lamps. Environmentally friendly UV LEDs are free of heavy metals, resistant to impact, and do not deteriorate due to frequent on/off, resulting in greatly improved reliability. Mercury lamps require complex drive circuits and a 15 minute warm-up time, while the VLMU5200-385-140 requires only a simple low-voltage circuit and does not require time to warm up.
Manufactured using InGaN technology, the typical irradiance power of the device at 500mA and 700mA is 2500mW and 3600mW, respectively, with wavelengths ranging from 380nm to 390nm. The emission angle of the VLMU 5200-385-140 is 140 ° C, and the irradiation intensity at 700 mA is 1054 mW/sr.
LED performance specifications make it ideal for UV curing in nail, dental and poster printing, blood and counterfeit detection, and photocatalytic purification. VLMU5200-385-140 meets the EU environmental protection (RoHS) and Vishay green standards, halogen-free, suitable for reflow soldering process, moisture sensitivity level up to J-STD-020 level 2.
