Violumas improved output for their UVA 320– 410nm LEDs

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 6.0x6.0 mm to 5.2x5.2 mm. The High Power Series increased in size from 7.0x7.0 mm to 7.2x7.2 mm for improved accuracy when placing the lens. The updated specifications are listed below:

Mid Power Series (VS5252C1L6):

Wavelength (nm) Typ. Optical Output at 700 mA (mW) Forward Voltage (Vf)
405 1285 3.7
395 1280 3.7
385 1300 3.9
375 930 3.9
365 775 4.1

High Power Series (VS7272C4L6):

Wavelength (nm) Typ. Optical Output at 700 mA (mW) Forward Voltage (Vf)
405 4900 7.4
395 4700 7.5
385 4650 7.6
375 3300 7.8
365 2850 8.2

In addition to high performance UV LED packages, Violumas is unique in manufacturing custom SMD and COB modules for 3D printing and epoxy/ink applications that require high wattage and uniformity requirements. Violumas also provides services in thermal management solutions and can offer full-system UV LED integration for unique 3D printing and curing projects.
