SynJet LED Cooling Helps Hospital Save 75% in Annual Energy Savings
To implement an affordable, durable and energy-efficient lighting solution that provided high quality illumination, the Arkansas Children’s Hospital decided to work with lighting specialist LumenOptix to swap its mercury downlights for LEDs.Contributing to aesthetics and affecting both facility functionality and patient care, lighting is a significant component of a hospital’s energy use. The canopy entrance of the Arkansas Children’s Hospital – lit with 100-watt mercury vapor downlights – once greeted its staff, patients and visitors with an unwelcoming greenish hue. The canopy lighting design also allowed room for nesting birds and insects, resulting in unsanitary conditions. Combine this with the fact that the mercury vapor lamps required frequent replacement, resulting in high operational and maintenance expenses, and the Arkansas Children’s Hospital knew it was time for an upgrade.
Each Lumenoptix LED Retrofit Downlight fits virtually any existing rough-in kit without tools and takes less than 10 minutes to install, which essentially eliminates labor and upkeep needs. The reflectors, engineered with low iridescent specular, semi-specular and diffused finishes, create a non-glare, evenly distributed and visually pleasing light.
Lighting a hospital in Arkansas is no easy operation. To ensure that the LED downlights perform at optimal capacity, they must be cooled properly and efficiently; and this cooling solution must be equipped to endure extreme temperatures and withstand the elements of humidity, rain and snow in Arkansas. To meet these thermal management needs, LumenOptix turned to the Nuventix SynJet as its cooling solution for its LED Retrofit Downlights.
The SynJet aims high-momentum, high velocity pulses of air directly to the LED lighting system’s heat sinks. Its patented oscillating diaphragm design allows the SynJet to then pull in cooler air behind the pulses while discharging warmer air, creating a more effective and efficient cooling system.In order to accomplish the desired, high-quality lighting with maximized energy efficiency, Lumen Optix utilized the Nuventix SynJet ZFlow 100 and Downlight LED Cooler 40W – specifically developed for cooling downlight LED lighting modules and arrays.
SynJet cooling technology is energy efficient, quiet and durable due to its frictionless design, which creates less heat and requires less energy than standard cooling solutions. Constructed with no ball bearings or joints that wear out, the SynJet module also eliminates dust and other particulate contamination, outlasts other active cooling solutions and extends the life of the LED light engines they support.
In addition to delivering the inherent strengths of synthetic jet cooling technology that enable brighter, quieter, energy efficient, reliable and longer-lasting LED lights, the Downlight LED Cooler 40W provides compact 40W of cooling with a 118 mm diameter – making it the ideal thermal management solution for retrofit LED downlights.
With SynJet’s effective cooling in a small and flexible form factor, LumenOptix is able to create easy-to-install downlights for retrofit designs such as those in the Arkansas Children’s Hospital – offering improved LED paybacks by minimizing installation costs and challenges.
Thermal efficiency is key in achieving innovative LED lighting solutions that allow hospitals to reduce costs of energy consumption while enhancing its physical environment. Along with cutting-edge companies like LumenOptix, the Nuventix SynJet continues to advance and bring lighting solutions that combine desired light quality and energy efficiency to maximize savings for commercial, industrial, warehouse and retail markets.
Taking advantage of the SynJet’s proven active cooling solutions, LumenOptix enabled the Arkansas Children’s Hospital to increase light output by well over 50%, improve color rendering for a whiter, crisper and brighter light, reduce costs with long-lasting, low-maintenance LEDs and achieve an astounding 75% in annual energy savings.
