Violumas Boosts 275nm and 265nm Output in Next Generation UVC LEDs

Violumas, provider of high-power UV LED solutions and inventor of 3-PAD LED technology, has launched new 275nm and 265nm LEDs in mid-power, high-power, and high-density packages.

Violumas, provider of high-power UV LED solutions and inventor of 3-PAD LED technology, is proud to launch the release of new 275nm and 265nm LEDs in mid-power, high-power, and high-density packages.

The radiant flux of the new 275nm and 265nm LEDs increased by 35-50% from the previous generation, to achieve 130mW (275nm) and 110mW (265nm) in compact, single-LED packages of 5.2mm x 5.2mm. The improved radiant flux of the UVC LEDs is achieved by the incorporation of a transparent p-Contact layer and high reflectivity metallization in the epi-wafer.

The new 275nm and 265nm LEDs are also available in 4-LED, 9-LED, and 16-LED chip-on-board (COB) configurations and provide unrivaled levels of power for any UVC application. Violumas’ high-density VC4X4 Series feature the most powerful single-emitter UVC LEDs on the market. With the development of higher power 265nm and 275nm LEDs, the VC4X4C48L9-275-V1 boasts an impressive 1650mW radiant flux while the VC4X4C48L9-265-V1 features 1400mW radiant flux.

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.

Due to the integrated thermal structure (3-PAD) in the Flip Chip LED and the Metal Core PCB, Violumas LEDs achieve rapid thermal dissipation rates and lower thermal resistance values. As UVC LEDs generate immense amounts of heat and require substantial cooling solutions, this technology 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 the continual development of high performance UVC LEDs, Violumas aims to accelerate industry adoption by providing a wide variety of products which can be suitable for any application from spectroscopy to disinfection.
