At present, luminous efficacy and cost remain the greatest barriers to broad adoption of LED lighting. However, it is anticipated that within several years, these challenges will be overcome. While we may think our basic lighting needs have been met, this technology offers many more opportunities than just energy efficiency: this research attempts to alter our expectations for lighting and cast aside our assumptions about control and performance. We will introduce new, low-cost sensing modalities that are attuned to human factors such as user context, circadian rhythms, or productivity, and integrate these data with atypical environmental factors to move beyond traditional lux measurements. To research and study these themes, we are focusing on the development of superior color-rendering systems, new power topologies for LED control, and low-cost multimodal sensor networks to monitor the lighting network as well as the environment.
