As LEDs continue to increase performance and reduce cost, the control of Color Temperature (CCT) and spectrum brings compelling features and challenges to the market. A discussion of fundamental features of spectrum control with a focus on Tunable White control is presented. The presentation includes: 1) a discussion of the categories of spectrum control ( Warm Dimming, Tunable White, Full Color Control), 2) Challenges with tunable white today (including feature and control challenges), and 3) possible benefits of Tunable White (why are we doing this?)

This will be an AIA CEU earning presentation.

Presenter: Tom Shearer

Tom Shearer is a Systems Sales Engineering Leader at Lutron Electronics. With an Electrical Engineering degree from Virginia Tech, and an emphasis on power electronics, and power conversion, he joined Lutron in 2001. He initially worked on the development of efficient low-cost dimming ballast technology, and in 2005, he worked on the development of digital dimming ballast products as the lighting industry realized the benefits of digital and wireless lighting controls. With the advent of LEDs for general illumination, he led the development of Lutron LED driver products that allow LEDs to achieve the same control performance as standard light sources already on the market. Tom has been awarded patents in the area of fluorescent and LED driver technology.

Tom has worked with many lighting designers and lighting fixture manufacturers to develop innovative control systems that meet the needs of our customers. He has worked on projects from high-end homes to museums to multi-building campuses to ensure control and LED compatibility, by coordinating control types and guaranteeing performance to mitigate risk in these large systems.

Tom in a member of the Illuminating Engineering Society (IES), and the Institute of Electrical and Electronics Engineers (IEEE), and has presented at technical seminars and conferences, including CEDIA and Strategies in Light on the topic of LEDs, LED drivers and lighting control in general.
