UV LEDs

With the number and variety of applications for ultraviolet (UV) light sources growing steadily, the LED is proving to be a serious contender for providing various intensities of UV light at reduced power consumption compared with traditional technologies. Applications range from photolithography and curing of various resins to biological studies and purification of water.

With careful choice of materials, UV LEDs can be produced with output wavelengths at various points in the upper part of the ultraviolet spectrum from 365 to 420nm. Power outputs and efficiencies are higher at the higher wavelengths, and for true high-power applications, the LEDs can be produced as multi-chip modules or arrays of several devices. Such high-power UV LED lamps are particularly useful in materials curing, with applications ranging from dentistry to electronics assembly and potting.

Pacer now offer a number of UV LED solutions including discrete LEDs, multi-chip modules and LED arrays and light engines. Epitex offers high power UV LED lamps mounted on a lead frame with a clear Silicon lens, UV surface mount TOP LED and high power TOP LED, high power UV LED arrays and high power UV illuminators. Excelitas ACULED is a high power UV light source using multi-COB technology.
