LTI Optics Staff Resume - Ryan Kelley

Ryan Kelley has been with Lighting Technologies since June of 2006 as an optical engineer. He has worked on a variety of optical design projects as well as material measurements, lamp modeling, Photopia support, and Photopia development. He has also participated in and given several Photopia training seminars.

Education

Ryan graduated from the University of Colorado at Boulder in May of 2006 with both Bachelors and Masters degrees. He completed these two degrees in just 4 years through the combined BS/MS program offered at CU. He was one of only 3 engineering students to graduate with a 4.0 GPA, earning him several awards that are listed below. His Bachelors is in Architectural Engineering with an emphasis in lighting, and his Masters is in Civil Engineering with an emphasis in building systems and lighting. Over the course of his education Ryan took 9 courses related to architectural lighting, including luminaire design and advanced radiative transfer. For his Masters thesis he created a method for analytically creating a revolved reflector shape for a spherical source to meet a required distribution. This method made use of a flashed area approach as well as the Tailored Edge Ray method of reflector construction.

  • Awards and Accomplishments:
    • Chancellor's Recognition Award for earning a 4.0 GPA throughout college
    • College of Engineering Academic Achievement Award
    • Dean's List Designation for all 8 semesters
    • Nominated for Colorado Engineering Council's Outstanding Senior Award
    • Most Outstanding Architectural Engineering Graduate
    • College of Engineering Academic Scholarships for every semester
    • Robert J. Besal Scholarship for Lighting Education

    • Optical Design Experience

    Ryan has had the opportunity to work on a wide range of optical design projects. In school he created revolved downlight, extruded wall wash and extruded indirect reflectors using analytic methods. Between his 3rd and 4th years at college, he interned in the optics group at Cooper Lighting's Peachtree City Georgia Customer First Center. In addition to several optical design projects, he had the opportunity to tour a photometric lab, manufacturing facility, anodizing facility, and spinning facility, gaining invaluable manufacturing experience. Upon joining LTI, Ryan has worked on a variety of optical design projects.

  • Optical Design Projects:
    • Redesigned upper and passive lower cones for a series of downlights
    • MH and CFL downlight lower cones
    • Created new design for square series of downlights
    • Type III and IV segmented roadway/area optics
    • Type V square and Type IV area light optics - spun with segmented inserts
    • Hydroformed plant grow light reflector
    • Minor surgical light with halogen lamp
    • Extruded LED lens
    • Lenses and reflectors for 4 and 6 LED arrays with varying beam spreads
    • Simulating photometry for skylights using Photopia
    • Created a spreadsheet tool to aid in design and analysis for extruded and revolved prisms

    • Employment Experience

    Ryan held 3 summer internships during college. For his Freshman and Sophomore summers he interned at Merrick & Co. as a mechanical engineer. There he designed and analyzed mechanical systems for laboratory and military facilities. During his Junior summer he worked at Cooper Lighting as an optical engineer. During the school year, Ryan worked for the Civil and Architectural Engineering Department in several positions. He helped to develop assignments and then acted as a teaching assistant for a department computing class that focused on Excel, Visual Basic for Applications, and Matlab. He also assisted in the Lighting Lab, completing construction of a new gonio-photometer.
