Violumas launches improved line of UVA SMDs (mid and high power)

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:

除了高性能 UV LED 封裝外，Violumas 在為需要高功率和均勻性要求的 3D 打印和環氧樹脂/油墨應用製造定制 SMD 和 COB 模塊方面也是獨一無二的。Violumas 還提供熱管理解決方案服務，可為獨特的 3D 打印和固化項目提供全系統 UV LED 集成。
