    Light Prescriptions Innovators’ Associate Dr. Juan Carlos Miñano has been named the 2010 recipient of the A. E. Conrady Award by the officers and directors of SPIE- the International Society of Optical Engineers. The A. E. Conrady Award is presented annually in recognition of exceptional contributions in design, construction, and testing of optical systems and instrumentation. The recognition of this award is based on developments of new equipment, techniques, and applications for designing, testing, analyzing, and/or evaluating optical systems, components, and theories.

    The SPIE Awards Committee recommended Dr. Miñano’s selection in recognition of his exceptional contributions in developing new design methods and devices in Nonimaging Optics. He will be honored at a yet to be announced SPIE meeting. A $2,000 honorarium is sponsored by Optical Research Associates.

    Other Recent Recipients of the A. E. Conrady Award include:

    2009 – Roland Winston
    2008 - Adolf Lohmann
    2007 - Elllis M. Betensky
    2006 - Virendra N. Mahajan
    2005 - David R. Shafer
    2004 - Juan L. Rayces
    2003 - George Hunter
    2002 - David G. Demaine
    2000 - Abe Offner

    Professor A. E. Conrady’s optical work led to a large number of new types of telescopic, microscopic, and photographic lens systems as well as most of the new forms of submarine periscopes and of other Service instruments developed after the 1st World War. The success of this work led to his appointment in 1917 to the principal teaching post of the newly-founded Technical Optics Department at Imperial College of Science Technology and Medicine in London.

    Professor Conrady changed the entire discipline of optical design by creating a systematic, process and applying many of his newly devised procedures and theoretical insights, The doctrine of the optical path length (OPL) and optical path difference (OPD) were two of these insights.

    Professor Conrady’s most important work was Applied Optics and Optical Design, (Oxford UP, 1929). This book laid out the basic system for the practical design of all kinds of optical instruments. The book is a classic which is widely used and referenced. Although its methods of computation have been superseded by computer “ray-tracing” lens design, the theory and mathematical insights remain valid.

    LPI completes a $1.4 million dollar R&D project for the DOE. The multi-year project, titled “SCALING UP: KiloLumen Solid-State Lighting Exceeding 100 LPW via Remote Phosphor”, developed several new solid state light sources using LPI’s patented “remote phosphor” technologies. The project was carried out in conjunction with OSRAM Opto Semiconductor and several subcontractors including Fisk University and Lawrence Berkeley National Laboratory. LPI was the primary contractor for the project, and co-funded, together with OSRAM, 20% of its costs. Several advanced product concepts came out of the project some which LPI plans to commercialize in the near future with is partners.

    LPI announces the development of new driver/dimming technology for solid state light sources. The patent pending system has significant advantages over existing systems which operate off of standard AC wall dimmer and typically utilize pulse width modulation of the LED light source/s. The new system, as opposed to currently available commercially units, can operate with virtually any existing AC dimmer without any degradation in performance. In addition, the new driver/dimmer exhibits no drop in efficacy at lower dimming levels. Another advantage is that the volumetric and component rating requirements (capacitors, etc) are reduced.

    LPI announces the development of a novel passive heat management system for applications using high power LED sources. The patent pending invention works equally well for solid state downlights or A-type replacement bulbs. It can enhance thermal performance by as much as 30% over conventional heat sink fins of the same size surface area. Another advantage of the system is that it performs equally well in a variety of orientations (horizontal, vertical, etc.). This is a particularly useful feature for screw-in replacements.
