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 epiwafer.

The new 275nm and 265nm LEDs are also available in 4-LED, 9-LED, and 16-LED chip-onboard (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.
