LED Light Strips and bulbs from LEDtronics deliver white light and cool, dependable, and rugged operation aboard Royal Danish Air Force medevac helicopters.
After a Royal Danish Air Force doctor seared his hand on a hot halogen light bulb that then burned out, the Danish Air Material Command, a procurement arm of the Danish air force, conducted a search for a cooler and more reliable lamp to illuminate medical-instrument tables on medevac helicopters. It found LED Light Strips from LEDtronics.
These strips fit existing cylindrical fixtures, generate 2,000 mcd of focused light, and draw 0.525 amp. They feature 105 narrow-beamed incandescent-white 0.197-in. domed LEDs mounted on a 27-in. long, 0.75-in.-wide printed circuit board.
In addition to their coolness, LEDs are well-suited for strenuous applications involving vibration and jolting because they integrate solid-state circuitry and sturdy epoxy lenses that make them practically unbreakable. Solid-state circuitry also enables LED bulbs to cycle on and off without sudden burnout. They operate up to 100,000 hr, and unlike when the filament breaks in a halogen bulb, LED cluster lamps continue to provide light even if one or more individual emitters fail.
In a prior medevac helicopter problem, the Danish Air Material Command replaced halogen bulbs in swing-arm task lights above examination tables with cool-operating, direct incandescent LED light bulbs. The LED bulbs produce a brilliant white light that makes it easy for medical personnel to see, assess, and treat patients' injuries.
This bulb's incandescent white light reportedly delivers superior color rendering, which lets medical personnel differentiate between tissue, blood, and other bodily fluids. But the true benefit, says the material command, is that the bulbs remain cool no matter how long they are in use.
