Plessey's High Brightness LEDs

With the focus on the global effort to reduce energy consumption and greenhouse gas emissions Plessey is bringing to market a range of high-brightness light emitting diodes (HB LEDs) for Solid State lighting applications.

HB LEDs are being designed into replacement products as well as architectural lighting, street lighting, commercial lighting and medical applications Plessey's MAGIC technology will enable it to offer LEDs that are significantly less expensive than anything that is currently available in the market. The more expensive LEDs are based on sapphire or Silicon Carbide, however Plessey's technology uses Gallium Nitride (GaN) on 6-inch silicon substrates. It uses a much thinner GaN layer at only 2.5μm compared to 6 to 8μm in other GaN on Si technologies. This technology delivers industry-standard performance at a dramatically reduced cost of manufacture. For the next generation products, Plessey intends to integrate its MAGIC HBLED products with its EPIC™ sensor technology to provide smart lighting solutions for even greater energy savings and carbon footprint reductions. dical applications

Plessey is bringing to market a range of high-brightness light emitting diodes (HB LEDs) for solid state lighting applications

Solid state lighting forms a significant part of the global effort to reduce energy consumption and greenhouse gas emissions.
HB LEDs are being designed into replacement products as well as architectural lighting, street lighting, commercial lighting and medical applications

Plessey's innovative products combine its strong R&D and operational expertise with the disruptive GaN-on-silicon technology from Cambridge

Plessey acquired the University of Cambridge spinout CamGaN in December 2011 (includes HB LED knowhow, IP and patents).

Plessey's proprietary GaN-on-silicon technology

Enables the growth of high performance gallium nitride (GaN) LED structures on large-diameter (6-inch and 8-inch) silicon substrates
Unique synergies with Plessey's 6-inch processing facility in Plymouth
Plessey is now positioned among the first commercial players to successfully manufacture HB LEDs on 6-inch silicon substrates
This technology delivers industry-standard performance at a dramatically reduced cost of manufacture with estimated savings of up to 80%

Plessey's goal: To become one of the first commercial players to successfully manufacture HB LEDs on 6" silicon wafers.

The price and performance of Plessey's MAGIC HB LEDs will drive an affordable switch from 60W bulbs to LED lamps.

The HB LED market is said to

Almost double its penetration into the global lighting market by 2020.
Save trillions of kWh of electricity, equivalent to the output of hundreds of power plants.
Reduce emissions of CO₂ by billions of tonnes.
Save hundreds of billions of dollars in energy savings.

As a consequence of these benefits the market for white LEDs is said to grow exponentially over the next decade.
