Violumas launches improved line of UVA (320nm – 410nm) LED

Violumas recently announced a 30% increase in optical output for all UVA SMDs. This increase can be attributed to their “Index Match” technology. The standard product line has a default radiant angle of 60°, and custom optics can be fitted for angles of 30°, 60°, 90°, 120°, and flat.


Violumas first revealed its surface-mount-device (SMD) product lineup with a focus on thermal dissipation at RadTech 2018 in Chicago, Illinois.


Violumas’ unique 3-PAD SMD structure optimizes heat dissipation from chip to heat sink via specialized thermal pillar MCPCB. Violumas SMDs have thermal resistance of 0.9°C/W, which is the lowest on the market.

Because Violumas’ SMDs exhibit exceptional thermal resistance, they can be driven at higher currents without experiencing dramatic thermal decay.


In regular applications, this directly corresponds to increased reliability and life span. But interestingly, Violumas’ industry-leading thermal characteristics make their products ideal for high power applications with extreme wattage and cooling requirements, opening up the possibility for new applications and deployments.

Violumas has also updated the form factor of the Mid Power Series by reducing the footprint from 6.0mm x 6.0mm to 5.2mm x 5.2mm.

The High Power Series increased in size from 7.0mm x 7.0mm to 7.2mm x 7.2mm for improved accuracy when placing the lens. The updated specifications are listed below:
