Guest Speaker: Naomi Miller, Pacific Northwest National Laboratory

With the excitement over LEDs, have we forgotten how a luminaire’s light distribution can support comfortable seeing, establish visual hierarchies, and pleasing composition? Learn where it matters, where it doesn’t, and how to evaluate distribution.

The market is being bombarded with low-cost LED luminaires that appear to solve the entire planet’s energy problem, global warming, and teenage acne. But so many of these produce blobs of light rather than precise optical control. This talk will examine where and when light distribution matters, and how it affects visual comfort and visibility, not to mention visual composition, for indoor and outdoor applications. It will also address glare metrics, and how the distribution of luminance across the luminaire itself may affect the glare response, even though that is not included in the glare formulae.

Learning Objectives
• Learn how to read and compare photometric distribution data to get clues on luminaire performance and visual comfort
• Recognize the kinds of light distributions best suited for specific applications
• Know when distribution matters, and where it probably doesn’t

NOTE: This presentation will be given twice, once in the city and once in the suburbs. Please be sure you are registering for your preferred location and date.
