SemiLEDs Expands Vertical UV-LED Portfolio

The firm is setting the standard with a breadth of offerings in III-nitride UV LEDs for industrial and specialty applications
SemiLEDs Corporation, an innovator in vertical UV-LED technology solutions, has released 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  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 deliver a 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 to 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 costs.

What's more, 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.

“SemiLEDs has consistently led the way in development of cost effective UV-LED solutions that efficiently provide a wide range of output options, delivering the UV light where and how it is needed," says Ilkan Cokgor, SemiLEDs Executive VP of Sales and Marketing.

“With the addition of the high-power N9, and mid-power P50N series, SemiLEDs has really opened up that area of the industrial market where both very high-output single UV-LED sources, and cost-effective UV-LED arrays, have not previously been available. Given the key advantages that UV-LEDs bring to the market, including increased efficiency and lifetime, reduction of hazardous substances, and the virtual elimination of heat in the beam, we expect this advanced technology will displace the inefficient, short-lifetime incumbents over the next few years."



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
