A good friend and emergency room doctor asked me one time – “can you design an LED high-output head-mounted fixture that I can use in the ER to look into areas of the body?” Â My friend’s question came out of the fact that apparently the existing head-mounted illuminators used in hospitals and doctor’s offices across the world are not necessarily the most convenient of apparatus to use. Â Most of them are also not made of LED sources, like this one:
Doesn’t this seem like a perfect opportunity for a high output cold white LED?
As I look at this image above that I got via a trade publication in the medical industry, I have to wonder what a high power source like Xenon is doing being used in an application like this when LED tech could easily be utilized. Â LEDs are also being used in several facets of the medical industry, including some of the large medical tasklights found in operating rooms and examination rooms.
Looking at this design, I had to ask myself why an S-video connection and composite is being used to send camera data instead of something digital like DVI or HDMI. Â Obviously there is no audio in this setup nor would there need to be. Â My concern is detail – if you’re looking at parts of the body that need examining after the fact, wouldn’t the best idea be to have your device outputting something HD? Â I’m probably looking at this medical technology and wondering how I could incorporate it into entertainment lighting or some effed up fascination like that.
My guess is that an LED source would make the cost of this device a hell of a lot less expensive, too. Â It would certainly last a lot longer!
Don’t worry, Welch Allyn, I’m not picking on you!
