George Craford of Lumileds opened the conference with a plenary presentation discussing general aspects of the LED industry. He noted that LEDs already dominate colored light applications, and 30-80?lm/W white LEDs are available merchandise while figures of 70-100?lm /W have been reported in the lab. Craford indicates that the timing of significant penetration into the general illumination market is hard to predict; however, he did predict that flat-panel televisions will be the next big market for the LED industry. Craford brief discussed the Luxeon K2, Lumileds new line of devices. These can be driven at 1500?mA, and have a low thermal resistance of 9?°C/W.
