RayVio claims record deep-UV LED cw power density of 30W/cm2

RayVio Corp of Haywood, CA, USA, which is developing and commercializing deep-ultraviolet (UV) LEDs and consumer disinfection solutions, says that it has demonstrated record-performance deep UV LEDs, resulting in a single-chip device capable of delivering 45mW of continuous power at deep-UV wavelengths from a 0.15mm2 emitting area, i.e. record continuous-wave (cw) power density of 30W/cm2 at the emission surface.

RayVio's core technology was invented by co-founder Dr Yitao Liao (chief technology officer) and professor Theodore Moustakas, and is exclusively licensed from Boston University. The technology is based on a proprietary and fundamentally different approach compared to techniques that have been attempted by the industry unsuccessfully for the past 15 years, it is claimed, enabling the firm to provide the highest optical power at the lowest cost than is otherwise commercially available. "This enables us to unleash Haitz' Law for deep UV LEDs, the same Haitz' Law that enabled blue and white LEDs to revolutionize the lighting and display industries," says Liao.  

RayVio says it is working with OEM customers to develop integrated products enabled by its UV LED devices. Applications range from digital curing to dermatology and biomedical instrumentation, as well as surface, air and water disinfection for consumers.

"Leading OEM and consumer electronics manufacturing partners have been evaluating our current products for the past several months, while we continue to install more capacity at our facility in Silicon Valley and ramp global supply chain partners to satisfy customer demand," says co-founder & CEO Dr Robert C. Walker.

Together with manufacturing and integration support located around the globe, RayVio reckons that its capital-efficient and scalable manufacturing process allows for rapid capacity expansion and lower manufacturing cost. The firm adds that such high-performance and cost effective UV LEDs make it possible to decrease system price, complexity and time to market.
