Hot Topics in Solid State Lighting and Illumination Webcast Series - Systems


View Archived webcast

Tuesday 13 November 10 AM PST

Chair- John Koshel, Senior Staff Engineer at Lambda Research Corp. (Littleton, MA), and Adjunct Assistant Professor, College of Optical Sciences/The Univ. of Arizona

Talk: Tolerancing of Illumination Systems

There is a wealth of material for the tolerancing of optical systems, but virtually all of this information is for the imaging sector. How does one tolerance an illumination system? First, Dr. John Koshel will present some simple methods to incorporate a perturbative method to analyze the tolerances of the illumination system. Second, Koshel will introduce a method to incorporate variation in the shape of the fabricated optic, especially injection-molded ones, such that the quality of the tooling and process time of the molding can be determined. In all cases, solid-state sources are used in this presentation. The end goal is to develop tools within illumination design and analysis software that will ease the design process.

The bulk of John Koshel's time at Lambda is spent working on illumination system design and algorithm development. He is also an adjunct assistant professor at The College of Optical Sciences, University of Arizona. Prior to Lambda he worked at Spectrum Astro and Breault Research Organization. He obtained his PhD in Optics from the University of Rochester. Koshel has chaired or co-chaired several conferences for SPIE, and is a co-author of the SPIE Press book Field Guide to Illumination.


Presenters - Pablo Benítez and Juan Carlos Miñano, Professors of Electronics, Optical Communications and Optics at Technical University of Madrid (UPM), CEDINT, ETSI Telecomunication (Madrid, Spain)

Talk: Advanced free form optics designs

Pablo Benítez, professor at the Polytechnic University of Madrid, Spain, is the co-inventor of the 2D and 3D Simultaneous Multiple Surfaces (SMS) non-imaging optical design methods. Dr. Benitez has extensive experience in the design and manufacture of advanced optical components for a variety of applications, including free space optical communications and high concentrating optics for use with photovoltaic cells. He has published 50 papers and articles with SPIE alone and taught a Non-Imaging Optics course at Optics + Photonics in 2006.

Juan Carlos Miñano is a professor at the Polytechnic University of Madrid, Spain. He has worked extensively in the fields of wireless optical links, photovoltaic solar energy, and illumination. Miñano has several patents in those fields, and is co-inventor of the 2D and 3D SMS design method. He has also been a conference program committee member for seven years in a row for the Nonimaging Optics and Efficient Illumination Systems conference.

Presenter - Ingo Speier, Photonic Research Physicist, Research Philips Lighting, BU Solid State Lighting (Burnaby, BC)

Talk: Aspects of Color Mixing Systems Design

Ingo Speier is Research Physicist with Philips Lighting, developing tunable white light technologies for general illumination. His objectives include SSL system architecture design, non-imaging optics design, and development of high brightness, multichip LED packages. Prior to his role with Philips Ingo was employed by Kodak (formerly Creo Inc.) where he worked on the application of high power diode lasers in imaging heads for the graphic arts industry. Ingo Speier holds a Masters of Physics degree from RWTH-Aachen in Germany.
