Violumas launches new 255nm, 265nm and 275nm LEDs in mid-power, high-power, and high-density packages
Violumas Inc of Fremont, CA, USA, a provider of high-power UV LED solutions and inventor of 3-PAD LED technology, has released its next-generation 255nm, 265nm and 275nm LEDs in both SMD and COB configurations.
The radiant flux of the new 275nm and 265nm LEDs has increased by 10–30% from the previous generation, to achieve 65mW (255nm), 130mW (265nm) and 145mW (275nm) in compact, single-emitter packages of 5.2mm x 5.2mm.
The new UVC LEDs are also available in 4-LED, 9-LED, and 16-LED chip-on-board (COB) configurations and provide what is claimed to be unrivaled levels of power for any UVC application. Each LED is encapsulated with a single, high-transmission fused silica lens that allows for long-term, stable performance over time. A selection of 30°, 60°, 90°, 120° and 135° optics is available to accommodate a wide variety of UVC applications.
The next-generation LEDs are also featured in Violumas’ VioBeam-1X1 ultra-narrow-beam LED, which features a unique 10deg fused silica optic for far-field and focused illumination.
The integrated thermal structure (3-PAD) in every Violumas LED achieves what is claimed to be industry-leading thermal resistance values, which is critical for more reliable, compact and long-lasting UVC LED systems. It also allows Violumas UVC LEDs to withstand a nominal driving current of 700mA per LED chip, at which the LED maintains >70% of its original intensity after 10,000 hours of continuous operation.
With continual development of high performance UVC LEDs, Violumas aims to accelerate industry adoption in high-power applications such as water disinfection, air purification, spectroscopy, and curing.
