UK's Plesse Semiconductor launches blue silicon-based LED products

Recently, Plessey Semiconductors announced the launch of its silicon-based potassium nitride manufacturing platform. The new product can provide 350mw of radiant power at 420ma.

As early as April this year, Pleas announced that it will introduce pl111010led products that demonstrate silicon-based GaN technology. These new LED products can be driven by continuous currents up to 1a and pulsed currents of 2a. The power of the new product is also higher than that of Plysee's silicon-based LED devices, which can be used in general solid-state lighting.

Although it is not yet known why Pleas only launched the blue version of this new LED design, it is certain that the device can be used in remote phosphor applications. The 435–460nm dominant wavelength range is similar to the royal blue LEDs introduced by major led manufacturers for remote ssl products; the company has not indicated whether it will introduce a white phosphor conversion version of this new LED.

The glamour of gan-on-si is the ability to produce lower cost LEDs with lower cost, universally available silicon wafers and automated back-end manufacturing tools.
