Cree releases brightest highest-efficacy colour LEDs


The silicon carbide (SiC) based LEDs are suited to architectural, vehicle and display lighting and come in a range of colours


Cree has announced the commercial availability of its XLamp XP-E2 colour LEDs


Samples are available now, and production quantities are available with standard lead times. Cree XLamp XP- E2 colour LEDs are available in red, red-orange, amber, green, blue and royal blue.


Former Osram GM joins GaN- on-silicon LED innovator Aledia


New board member Bernhard Stapp brings more than a dozen years of executive experience in LED lighting technologies to Aledia


Aledia has announced that solid-state lighting (SSL) industry veteran Bernhard Stapp is now on its board of directors.


XLamp XP-E2 LED


The new XP-E2 colour LEDs deliver up to 88 percent higher maximum light output compared to alternative high-power colour LEDs.


This enables lighting manufacturers to more cost- effectively address a wide spectrum of applications, such as architectural, vehicle and display lighting.


Built on Cree’s SC³ technology next-generation LED platform, the new XP-E2 colour LEDs deliver higher lumens-per-watt and lumens-per-dollar compared to the original XP-E colour LEDs to lower system costs for existing XP-E colour designs.


The latest XP-E2 colour LEDs leverage the same XP footprint (3.45 mm x 3.45 mm) and are optically compatible with the original XP-E LED. This provides drop-in-ready performance enhancements to shorten design cycle and improve customer time to market.


“We are excited that Cree is offering higher-performance color LEDs in the XP footprint,” says Greg Campbell, executive vice president and chief technology officer, Lumenpulse. “The brighter XP-E2 colour LEDs enable Lumenpulse to continue to provide innovative, high- performance LED lighting systems.”


XLamp XP-E2 colour LEDs deliver up to 1409 mW for royal blue, 109 lumens for blue, 253 lumens for green, 203 lumens for amber, 193 lumens for red-orange and 155 lumens for red, all at maximum drive currents in the 3.45 mm x 3.45 mm footprint.

Aledia is a developer of WireLED, a new microwire- based 3D LED technology that dramatically cuts manufacturing costs compared to conventional planar (2D) LEDs.


Most recently he has been in senior management positions at Osram.


As general manager and senior vice president of Osram AG’s SSL unit, Stapp was responsible for the company’s professional LED and OLED business.


Earlier, as SSL vice president and general manager at Osram Opto Semiconductors, he launched and managed the general-lighting LED business and oversaw launch of the world’s first OLED lighting products.


Prior to that, Stapp was vice president and CTO of the semiconductor company, where he oversaw global LED, laser and OLED R&D. Earlier in his career, he held a variety of management positions in Siemens AG’s Corporate Technology division.


“Aledia’s mission is to bring fundamental change to the world’s lighting markets by making LED technology substantially more affordable and more versatile, with better performance and fewer limitations,” says Giorgio
