Violumas

What Violumas does

Violumas is the dedicated UV LED division of COFAN Group, founded in 2016 and headquartered in Fremont, California, with additional operations in Concord, Ontario (Canada) and Lung-Tan, Tao-Yuan (Taiwan). The company designs, manufactures, and sells high-power UV LEDs in SMD packages (low, mid, and high power) and Chip-on-Board (COB) modules spanning wavelengths from 255nm UV-C through 405nm near-UV, alongside complementary specialty optics (the VioBeam-1X1 narrow-beam line) and thermal management accessories (heatsinks and drivers). Its core differentiation rests on two patented technologies: the 3-PAD (Triple Pad) flip-chip bonding process and the Super Pillar MCPCB (Metal Core Printed Circuit Board), which together deliver thermal resistance as low as 0.9°C/W in COB configurations — materially better than the 4–20°C/W achieved with conventional SMD + MCPCB combinations — enabling UV LEDs to be driven at 700mA per chip with >10,000-hour R70 lifetimes.

The company operates a vertically integrated business model spanning epitaxial wafers to finished modules and offers custom UV LED design services supported by optical simulation tools (Zemax, LightTools). Revenue is generated primarily through hardware sales via direct enterprise sales (with field sales engineers), two named distribution partners (Boston Electronics and AUTEX), and an academic research subsidy program that supplies subsidized products to publicly-funded researchers in exchange for shared results. Target end markets include medical device sterilization, surface and air disinfection, water sterilization (as a mercury-lamp replacement), additive manufacturing / UV curing, and academic research, with documented case studies in each vertical. Notable commercial engagements include a first-of-its-kind 8m³ atmospheric chemistry chamber at the University of British Columbia powered by 792 Violumas LEDs delivering over 300W of optical output.

Operationally, Violumas is a wholly-controlled subsidiary of COFAN USA, a thermal management specialist established in 1994, and it leverages the parent's PCB/MCPCB manufacturing footprint across the US, Canada, Taiwan, and China. Leadership comprises a CTO (Pao Chen, PhD), a Director of Applications Research (Pratibha Sharma, PhD), and a Director of Engineering & Production (CY Wu) on the technical side, with business development led by Saya Han and Peter Chung. No external funding rounds, acquisitions, or ownership changes are disclosed; the company operates as an internal corporate division rather than a venture-backed entity.
