According to the company, its UV LEDs give up to 10 times longer lifespan or up to 50 percent cost savings, up to 70 percent energy consumption savings and improved light performance compared to CCFLs.
The QuasarBrite UV LEDs are suitable for counterfeit detection of currency, passports and other travel documents; forensic analysis of bodily fluids; and as photo catalysts for air and water purifiers in homes, offices and automobiles.
"Previously widespread use of UV LED technology, especially in the shorter UV wavelengths, was hindered because the materials used in the epoxy LED lens degraded the life span of UV LEDs to less than 5,000 hours," said Kay Fernandez, product technology manager at Lumex. "Recent technological developments have allowed the epoxy lenses to be replaced by a robust TO-46 package with a glass lens, making it possible for QuasarBrite UVs to last 10x longer—with life spans of over 50,000 hours."
QuasarBrite UV LEDs provide a uniform beam pattern and does not use the hazardous mercury material found in CCFL technology. They are also sport more durable designs, thereby significantly reducing maintenance costs.
The RoHs-compliant 355nm, 365nm and 377nm QuasarBrite UV LEDs feature 80° viewing angle and operating temperatures ranging from -40°C to 100°C. Samples are available with a lead time of 18–20 weeks.
