Title: A Spectrally Dynamic Berth Light for Active Circadian Cycle Management
Agency / Branch: DOD / DARPA
Contract: W31P4Q-09-C-0161
Award Amount: $99,000.00


Energy Focus has envisioned a Generation 2 berth light LED system that incorporates an illumination spectrum consistent with the latest research in spectrally tuned adjustment and resetting of circadian rhythms. Research shows that the human eye contains specialized receptors for 420nm-560nm light which signal the body to suppress melatonin production. In the absence of this light, the body is signaled to produce melatonin, promoting sleep. The Generation 1 SSL berth light design will be exploited to provide a device with enhanced illumination options. During this project, spectra will be identified for general illumination and circadian modification along with the identification of the proper timing required for circadian modification. The target illumination patterns will be developed based on current Mil Specifications and the optical system. The updated berth light will be further refined using computer modeling. A prominent feature of this next generation system will be simple controls accessible to the user. The controls will allow the user to set the system to correspond with their individual sleep-wake requirements. Effort will also be directed to developing SSL driver specifications. The cost proposal associated with this work is included as the last page of the technical proposal.
