SemiLEDs Corporation N9 and P50N UV-LED series

SemiLEDs Corporation has released two product families - the 10 W high-power N9 series and the 0.17 to 0.5 W mid-power P50N series. Both families use SemiLEDs’ patented vertical LED structure that is claimed to deliver good performance in directional industrial applications such as printing, coating and curing, as well as specialty applications including signage and medical/cosmetic use.

The N9 series, housed on a 9 x 9 mm ceramic package, is offered in wavelengths from 385 to 420 nm in 5 nm bins. Drive currents up to 1000 mA deliver typical output of 5000 mW of optical power at the nominal 350 mA drive rate at 30 V.

The lambertian output distribution is compatible with secondary optics to allow precise control of the high-intensity UV light. Compared to the standard 1000 to 4000 h life of the incumbent UV lamp technologies, vertical UV-LED systems support lifetimes of up to 50,000 h under optimal thermal management conditions, thereby decreasing system maintenance requirements.

With instant on/off capabilities and a compact point-source that is compatible with a variety of optics, the UV-LED allows solution integrators to eliminate components such as mechanical shutters or focusing windows.

The mid-power P50N UV-LED series consists of a complete product family available for 0.17, 0.34 and 0.50 W drive options, delivering up to 140 mW of output, for wavelengths from 385 to 420 nm in 5 nm bins. The 5 x 5 mm package is suitable for integration into compact arrays or for backlight elements in UV-driven signage.

The selection of output combinations simplifies the system integrator’s task by allowing a common design platform for portable device applications, such as cosmetics or health care, where differing performance profiles are needed to address separate curing or treatment functions.
