Sensory Lighting System and Method for Characterizing an Illumination Space

Rensselaer researchers have developed a smart, efficient, aesthetically pleasing, solid-state lighting system for homes and commercial spaces. Over 35% of the energy consumed by illumination can be saved by using advanced lighting control systems; however, these systems require frequent calibration and programming to adjust to interior redesign of the space and personal lighting needs. This technoloby involves LED fixtures that encode illumination with a time modulated data signal and incorporates a sparse network of low pixel light sensors distributed throughout the system.

Self-commissioning daylight switching system

This invention is directed to a self-commissioning photosensor and controller device that turns electric lights on and off using a microprocessor connected to a luminaire. The processor receives signals from a self-commissioned mountable photosensor. The photosensor uses a unique algorithm to control illumination at the task pane making the photosensor more accurate than current market technologies. Light energy consumption can be reduced by up to 30% and commercial customers can be recompensed in as soon as one year after installation.
