LedEngin, a solid-state lighting company based in California, has introduced 1700 mW (365 nm) and 6000 mW (400 nm) UVA power LED emitters in its LZC-series 12-die platform.
The LedEngin emitters have a compact form factor of 9X9 and provide high optical system efficiency and flux densities of up to 600 mW and 10 W/cm2 at 400 nm and 1700 mW and 10 W/cm2 at 365nm. They utilize LED packaging technology and features low thermal impedance. The emitters feature a surface-mounted ceramic package that has an integrated glass lens, which is resistant to ultraviolet. This feature increases the lifetime of the emitters by reducing the degradation related to packaging. Packaging failure modes that normally occur are also eliminated due to the stress free and thermally matched ceramic package. The LED emitters have a JEDEC Moisture Sensitivity Level 1 and are also RoHS Compliant.
The record high flux densities of the UVA wavelength emitters enable them to be used in a wide range of applications such as high speed ink printing, forensics detection, sterilization, currency verification, non-destructive testing analysis and adhesive curing. The emitters will help replace toxic, power hungry Mercury lamps.
LedEngin offers the LZC-UV Series in flattop optic and standard half sphere glass dome designs.
