Day 1 - Tuesday 4th October 2011

Workshop A: Thermal Management for LEDs & Solid-State Lighting

09:00 – 12:00

Room: Visconti 1

Thermal management is a critically important factor influencing the success or failure of LED-based lamps and luminaires. Temperature has a direct affect on the performance and long-term reliability of LED-based fixtures, meaning that appropriate steps must be taken to protect the LEDs from unwanted heating situations. This workshop will discuss such issues in detail, looking at ways in which different LEDs, materials and designs can influence heat transport and junction temperature. Speakers will discuss the role of metal-core PCB substrates; the use of flexible graphite as a thermal-interface material and as a heat spreader; and the use of technologies such as stamped circuit boards and nanoceramic aluminium substrates. The various applications of thermally-conductive plastics will also be described. Participants will have the opportunity to discuss these technologies in detail and see practical, hands-on demonstrations.

Workshop B: Light Measurement for Solid-State Lighting

12:30 – 15:00

Room: Visconti 1

As LED-based lamps and luminaires continue to replace conventional light-source technologies in a range of general-illumination applications, particular attention is now being paid to light quality, including issues such as uniformity and binning. Besides the basics of light measurement, this workshop will discuss the optical properties of LEDs, and how these properties can be measured in line with existing and developing standards (CIE127, DIN5032). It will explain the different types of equipment needed for accurate optical measurements in the lab and in the production line. Furthermore, aspects of color quality such as color temperature and color-rendering index will be discussed. Participants can expect to learn how to evaluate the optical performance of LEDs and LED assemblies, as needed for the successful development of LED-based fixtures and luminaires
