SemiLEDs broadens vertical UV-LED portfolio with mid- and high-power offerings

TAIWAN: SemiLEDs Corp. announced the release of two new product families, the 10-watt high-power N9 series, and the 0.17 to 0.50-watt mid-power P50N series.

Both product families take advantage of SemiLEDs unique patented vertical LED structure that delivers superior performance in directional industrial applications, such as printing, coating and curing, and specialty applications including signage and medical or cosmetic uses.

The N9 series, housed on a 9 x 9mm ceramic package, is offered in wavelengths from 385 to 420nm in 5nm bins. Drive currents up to 1,000mA delivers typical output of 5,000mW of optical power at the nominal 350mA drive rate at 30V. The lambertian output distribution is highly compatible with secondary optics to allow precise control of the high-intensity UV light.

Compared to the standard 1000-4000 hour life of the incumbent UV lamp technologies, vertical UV-LED systems support lifetimes of up to 50,000 hours under optimal thermal management conditions, thereby decreasing system maintenance requirements in applications where even planned downtime carries substantial monetary costs.

In addition, with instant on/off capabilities and a compact point-source that is compatible with a wide variety of optics, the SemiLEDs N9 UV-LED allows solution integrators to eliminate maintenance-intensive components such as mechanical shutters or focusing windows. High-output UV sources are commonly used in semiconductor and electronic photo-resistive etching or processing, as well as high-throughput printing systems, and larger scale industrial bonding or curing applications, often eliminating the need for toxic solvents.

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

The wide 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.
