Record claim for UVC LED
The device will be used to accelerate the adoption of UVC LEDs and hasten the widespread replacement of low-pressure mercury lamps.
While the new device will retain the Klaran 3.5 mm x 3.5 mm package and solder pad design to allow backward compatibility with existing customer designs, the higher output will allow UVC LEDs to meet the performance and cost targets needed to expand into new applications in high-flow water and air treatment.
The new single-chip UVC LED design uses a rigid fused silica lens and a thin layer of proprietary UVC transparent resin developed by Asahi Kasei specifically to withstand the intense UVC output.
In contrast to soft molded lens, the rigid fused silica lens allows higher transmission of the UVC light which ensures stable long-life performance and high-temperature stability. Asahi Kasei leveraged its long-running expertise in the field to develop the proprietary resin after a careful and lengthy evaluation of commercially available adhesives resulted in no suitable candidate.
“This new high-output and long-life Klaran device is made possible by the strong cooperation between Crystal IS and Asahi Kasei innovation teams,” said Eoin Connolly, President and CEO. “With this new device in our portfolio, Klaran UVC LED devices make another significant step forward in replacing low-pressure mercury lamp technology and promoting the transition to non-mercury/non-ozone generating devices.”
