        LED lighting is frequently discussed as a key element of the green and sustainable lighting solution that will lead to significant savings in energy usage. Its adoption is spreading as standards proliferate and costs come down; but there is still a significant gap in the understanding of the potential and reality.
        This workshop is intended to help fill that gap by providing an overview of the technology and applications. Manufacturing, reliability, and thermal management, etc will be discussed. There will be demos and hands-on exhibits that attendees may explore during the break.

    Intended Audience:
        Engineers involved in the design, manufacturing, and use of lighting; semiconductor and other engineers will find this particularly interesting as they explore career opportunities in closely related fields. Also suitable for managers and engineers considering LED lighting for their existing or new facilities.

      1: Introduction

      2: Foundational Principles - History of Lighting
        - Eye: How we see, perception of color
        - History of Lighting
        - Lighting Terminology

      3: LEDs 101
        - Building a "lamp" Assembly
        - Power Electronics
        - Thermal Management

      4: Building a Luminaire

    BREAK (including lunch): 12:30-1:45
    (touch-feel display and lamp tear-down etc demos at lunch)    

      5: Comparison of LED Lighting vs. other lighting solutions
        - How LED lighting changes our world

      6: The truth about LED Lighting (facts and fibs)

      7: Future
        - OLED, Laser, Plasma, ESL, Lighting Services

      8: The business case for LED lighting

      9: Career opportunities in LED lighting for you as an engineer    

      10: Wrap up and Drawing for Pre-Registrants
