INNOVATOR IN BLUE ADAPTS LEDs FOR CONSUMERS

摘要

John Edmond, chief technology officer of LED-lighting manufacturer Cree and one of the pioneers in HB LEDs, sees the challenge confronting the HB-LED industry: "Lumens per watt per dollar summarizes the challenge on a macroscale," he says. As chief technology officer of Cree, though, he directs development on a microscale and must figure out the best approach to increasing light output, measured in lumens, while consuming less power, measured in watts, and reducing the cost of the end product to compete with incandescent and fluorescent technologies. Edmond has worked to create and refine blue LEDs-the engines behind HB LEDs-for his entire career. He started Cree with five other founders while fresh out of the doctoral program at North Carolina State University, and, other than a stint as a paper boy, it's been his only job.
