According to a recent article in LEDs magazine, LED headlamps are currently being developed for surgeons to use. Given that, I think it’s safe to say that LEDs have well-established themselves as the revolutionary technology of the future. It’s like my granddad always used to say: “If it’s good enough for surgeons, it’s good enough for you.” Okay, so that’s not exactly what granddad used to say, but you get the idea.
Generally, surgeons use Xenon-based systems which require a separate mount with a fiber-optic cable running to the surgeon’s headset. Not only does this restrict movement, but it creates potential electrical and overheating hazards.
As a solution, battery-operated LED headsets are being developed to reproduce the same amount of light (more than 350 watts) without the need for cables or electricity. The major obstacle here is producing enough light without the headlamp generating too much heat. As oftentimes surgeries require a number of hours to complete, an efficient LED headset would need to remain cool on the surgeon’s head for extended periods of time.
The initial solution to this obstacle was liquid cooling systems, however, developers are currently exploring the benefits and efficiencies of air cooling.
