October Meeting – Past President’s Night

Honoring our IES Chapter 38 Past Presidents


Optical Design for Architectural Lighting


Every optical design application has a set of standards by which it is judged. Sometimes, these standards are written (IES publications) with recommended quantities which are highly dependent on photometric measurements. Such standards include the Luminaire Classification System of BUG rating (TM-15) and the lumens/W. These are relatively straightforward for incorporating them into lighting ordinances and energy codes.  Yet, there are some instances where photometry may be an insufficient guideline, neglecting to indicate glare or beam uniformity, since a photocell can never duplicate our visual response. Only a luminaire mock-up can reveal to the specifier what the photometric report cannot. Further, it is possible the advent of LED lowered these aesthetic considerations by which good lighting is judged. This presentation will attempt to navigate these tricky subjective and aesthetic considerations through a series of concrete examples from the presenter’s 24 years of optical design experience.


Wailam Wilson, LC.  Senior Engineer – Optical Design at ConTech Lighting

Presenter bio

Wailam Wilson’s lighting education was done at Univ of Colorado (under Prof David DiLaura) and Univ of London (under David Low). Over the course of 2-plus decades she designed optics for Hubbell (Prescolite), Eaton (Cooper Lighting), and Leviton (ConTech Lighting) for both indoor and outdoor application. She has designed for most lamp sources but only LEDs in the last decade. The manufacturing  processes used to make these optics include: injection molding, lens extrusion, glass molding, reflector spinning, segmented optics, and hydroforming. Industry recognition include SSL-PIA, Lightfair Innovation Award, and Progress Report selection.
