Crystal IS released the WD series LEDs of UVC LEDs as an expansion of its Klaran® UVC LED platform. The company says that the Klaran WD Series marks the first example of a UVC LED that has broken the $0.25/mW price barrier needed to mass produce UVC LED-based water purification products.
Crystal IS says it developed the WD series specifically for the price and performance needs of point-of-use water disinfection.
The company plans to initially sell 30 mW and 40 mW alternatives and launch of more powerful UVC LED models in the coming months.
“Our Aluminum Nitride substrates have always held the promise of superior cost for performance at the deep UV wavelengths,” said Larry Felton, CEO of Crystal IS. “Klaran WD series LEDs, developed specifically for point-of-use water, meet OEM requirements at a compelling price per milliwatt to drive innovation in water purification products.”
The company says that the Klaran WD series LEDs let OEMs address the rising global demand for water purification products as the increase in water pollution combined with the surge in industrialization and urban population propel consumers to more actively ensure the quality of their drinking water. The Asia Pacific region, specifically China and India have the greatest need for water purification and disinfection.
Klaran WD Series Characteristics
Crystal IS fabricates the unique ultra-wide bandgap Aluminum Nitride substrate upon which the WD series is produced. This substrate reportedly overcomes the inherent challenges of traditional sapphire-based devices. It emits the LED’s full germicidal power from the top of the chip, thereby, allowing for low cost and less complicated packaging design. The resulting UVC LEDs deliver high output at peak germicidal wavelengths of 260-275 nm. And for more potent disinfection, they can be driven at higher currents.
Crystal IS Notes That Wavelength Range Offers Peak Effectiveness Against E. Coli and MS2
The Klaran WD series operates at a low DC voltage, and the drive current is rated up to half an amp. The device features a 105˚ viewing angle. According to Crystal IS, the series offers a wavelength range that provides peak effectiveness against E. Coli and MS2.
The company claims that the UVC LEDs offer design flexibility for close-proximity disinfection of heat sensitive surfaces.
Furthermore, the company says that the WD series is perfect for use in applications that require multiple LEDs to irradiate a large area. Also, its compact point-source is said to be ideal for complex and hard-to-reach surfaces.
Pricing and Availability
The Klaran WD series is now available and it comes in 1,000 piece reels for high volume cost efficiency.
