From Nitrides to Night Skies: Energy, Health, Horticulture, and Ecological Implications with LED Lighting Technology
The emergence of LED lighting technology is a technical revolution similar in scale as the invention of the electric incandescent lamp and the switch from candle and gas lighting to electric lighting. LED lighting has improved lighting performance and lifetime with dramatically increased power efficiency. LED technology also enables reduced energy consumption through improved control of intensity, optical distribution, and spectral power distribution. These features also enable new lighting values and applications. LED technology enables efficient provision of light that can improve human health on a broad scale, it enables efficient indoor plant production, and it can reduce light pollution and ecological impacts of light on the environment. This talk will cover the status of LED technology and application and research examples for human health, plant production, and ecological impacts. In particular, basic guidance for healthy lighting will be described. Skyglow/light pollution measurements from Santa Barbara, Santa Cruz Island, and Cuyama CA will be presented. And, ongoing horticultural lighting research and lighting product designs and considerations will be shared.
Morgan Pattison has a PhD in Materials Science from UCSB with thesis research on GaN based micro-cavity LEDs advised by Professor Shuji Nakamura. Upon graduation in 2006 Morgan went to work for the DOE National Energy Technology Laboratory based in Morgantown, WV, managing R&D for the DOE SSL R&D Program. After 2 years with the DOE, Morgan started an LED and lighting focused technology consulting business, SSLS. He has continued to consult to the DOE for over 13 years, acting as Senior Technical Advisor.
