Plessey Semiconductors Ltd of Plymouth, UK has announced availability of its next-generation gallium nitride -on-silicon (GaN-on-Si) mid-power LEDs. The product family doubles the luminous efficacy of the firm’s first-generation MAGIC (Manufactured on GaN-on-Si I/C) products launched in February. Plessey says that, using standard silicon production techniques, it is able to achieve high-flux-output LEDs at substantially lower cost. The PLW114050 is the first in a family of entry-level LED lighting products to be released.
“We have made great strides forward in refining, productizing and improving our patented MAGIC technology,” says chief technology officer Dr Keith Strickland. “We have a roadmap that puts MAGIC ahead of the efficacies achieved by sapphire-based LEDs and, thereby, sets a new milestone in terms of lumen/$ performance,” he claims. “By approaching efficacy parity, we are accelerating the widespread adoption of GaN-on-Si LED-based lighting products. Our MAGIC LED products have a cost advantage over comparable sapphire-based LEDs as we use 6-inch, high-yield, standard, automated silicon manufacturing technology,” Strickland continues.
“Customers are delighted that a European company is committed to developing and manufacturing world-class GaN-on-Si LEDs,” claims chief commercial officer Dr Jose Lopez. “The market currently has many suppliers of LEDs, but the quality and reliability can be variable,” he adds. “Plessey is a trusted brand with a 50-year plus track record of manufacturing products to the highest standards.”
The PLW114050 is available in a correlated color temperature (CCT) range of 6500-2700K, with a Lambertian distribution in an industry-standard 3020 package. With a drive current of 60mA, the typical forward voltage is 3.2V. Additional package options will be made available.
