The high-power ultraviolet (UV) series of LEDs from Lite-On features a compact design and a high-intensity output, allowing users to replace conventional UV lamps as the light source for curing, printing, sterilisation and deodorisation applications.

It combines the small size and long operating lifetime of an LED with the high brightness of conventional UV light sources. Users who replace conventional UV light sources with Lite-On UV LEDs can therefore benefit from lower energy and operating costs and from a reduced requirement for maintenance and repair.

The LTPL-C034UVx is a series of lens-type high-power UV LEDs, available in a wide choice of peak wavelength options.

Lite-On also supplies the LTPL- C16FUVM405, a UV LED with a peak wavelength of 405nm housed in a smaller 1.6mm x 1.6mm x 1.38mm package. Drawing a forward current of 20mA and operating at 3.1V, it supplies a radiant optical flux of 22mW. Its viewing angle, or directivity, is 135°.

In addition to these LEDs operating in the UV-A range of 315-400nm, Lite-On offers LEDs for the UV-C range of 200- 260nm. These are used in disinfection applications, to kill or inactivate micro- organisms by destroying nucleic acids and disrupting their DNA. These UV-C LEDs are mainly used in equipment for food, air and water purification.

The typical package size for these LEDs is 6.0mm x 6.0mm x 1.6mm, drawing drive currents of 20mA, 100mA and 350mA to provide outputs of up to 32mW. Reliable UV-C LEDs from Lite-On, which are based on unique patented package technology, enable users to widen the field of addressable UV applications.
