Spanos Auditorium

This seminar is part of the Jones Seminars on Science, Technology, and Society series.

Light Emitting Diodes (LEDs) have reached the commercial market in a number of niche applications, such as flashlights, Christmas lights, and traffic control lights. LEDs have been promoted for high efficiency lighting. Both semiconductor LEDs and organic LEDs are being developed. What is their technical status? What are the barriers to acceptance by consumers? What is the status of illumination in today’s homes and commercial/industrial settings? What government policies are in place to maximize lighting efficiency? How much energy savings is possible through converting to LEDs? What can the consumer expect in the near future?
