Lighting-LED Quantum Leap

“HUMANCENTRIC”

“Kelvin” : The Color of The Sun Sun’s Color Varies During The Day Sun’s Color Affects Our Body’s Circadian Rhythm

Biologic light supports the day/night rhythm

automatically, it promotes and maintains health and performance

“HUMANCENTRIC LED LIGHTING” New LED’s Easily Adjust Kelvin

Adjusting the Kelvin… Affects Our Body’s Circadian Rhythm

Quicker Healing of Patients Reduced Need for Care Due to Stabilization

of the Circadian Cycle of Older People Orientation and Prevention of Falls Due to

Increased Physical Performance Reduction of Medication

Secret Ingredient

“Johns Hopkins identifies mammalian intrinsically photosensitive retinal ganglion cells (ipRGCs) & melanopsin as affecting non-visual photic responses, such as behavioral responses to light, pineal melatonin synthesis, sleep latency and pupillary light reflex.”

A Prospective Study of Patients Undergoing Spinal Surgery

The exposure postoperatively of patients who have undergone spinal surgery to increased amounts of natural sunlight during their hospital recovery period may result in decreased stress, pain, analgesic medication use, and pain medication costs

The patients housed on the bright side of the hospital(46% higher intensity sunlight on average) used 22% less analgesic medication in all age quartiles.

Capital Improvement & Energy Efficiency

Go Hand-in-Hand

Healthcare Facilities Management Magazine – Trends in Healthcare: “More facilities are reinvesting in infrastructure by replacing older boilers, chiller and air handlers with more efficient units and increasing spending on control systems to achieve tighter operational parameters.”
