An LED Surgical Headlight Camera System?

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?”  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.  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.  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.  Obviously there is no audio in this setup nor would there need to be.  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?  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.  It would certainly last a lot longer!

Don’t worry, Welch Allyn, I’m not picking on you!

Luxim’s Light Emitting Plasma + A Hydrogen Fuel Cell = Win

More news out of our favorite high output lamp technology from Luxim – a hydrogen fuel cell paired with Luxim’s Light-Emitting Plasma technology made its appearance at a celebrity gathering lately, debuting the first mobile fuel cell powered entertainment lighting application.

Check out the press release:

FUEL CELL-POWERED MOBILE LIGHTING SYSTEM FEATURING LUXIM’S LIGHT EMITTING PLASMA TECHNOLOGY DEPLOYED AT ACADEMY AWARDS®

SUNNYVALE, Calif., Mar. 23, 2010—At the Academy Awards® ceremony held earlier this month, a new mobile lighting system incorporating Light Emitting Plasma™ (LEP) from LUXIM and a clean hydrogen fuel cell was deployed at the celebrity gathering, infusing the festivities with a brighter, cleaner sparkle.  The novel mobile unit was recently developed by a team of collaborators as a more efficient alternative to traditional technologies powered by diesel fuel generators.  In addition to LUXIM, the team consisted of Sandia National LaboratoriesThe Boeing Company, the California Department of Transportation (Caltrans), Altergy SystemsMultiquip Inc., and others.

The use of the new system marks a major departure for this kind of high-intensity entertainment lighting application.  Up to now, mobile lighting units were powered by diesel fuel generators that produce carbon dioxide, nitrogen oxides and soot, making them less than ideal for the environment.  Before this technology arrived, mobile lighting units typically consumed 4.4 kilowatts.  The LEP system consumes only about 2.3 kilowatts for the same light output, a reduced power requirement that saves energy and increases the system duration (operational time between refills).

Said Geoff Browne, LUXIM’s Vice President of Sales, “It’s a thrill to see our technology deployed at such a high-profile venue.  The fuel cell mobile system featuring LEP is an especially good fit for the entertainment industry.  It meets film production sound levels, maintains zero exhaust emissions and can be used for indoor and outdoor film shoots.  But beyond the novelty of deployment at a highly visible Hollywood entertainment event, LEP is gaining steady adoption in multiple other important commercial venues like street and area, and general lighting.   It’s simply the most powerful, efficient and cleanest light source for new-generation high-intensity applications.”

LUXIM is the world leader in Light Emitting Plasma technology, having shipped more than 50,000 products under its LiFi™ brand.  These products are used in applications as varied as projection display, medical instruments and entertainment lighting.  In each application the technology has brought dramatic improvements in efficiency, life and color quality.  LUXIM is now bringing the benefits of Light Emitting Plasma technology to the area lighting market with the goal of playing a meaningful role in reducing the planet’s energy consumption and abating climate change.

NEMO: A LIFI Color Engine

Seachanger, the color mixing engine that you attach to a Source Four ellipsoidal, has just announced that they are selling a high-output color engine that runs on a LIFI lamp.  LIFI – I blogged about this a few days ago, but it means “Light Fidelity.”  It’s a high output lamp, very efficient, and uses plasma.

Plasma.  The NEMO is 83 lumens per Watt.  EIGHTY THREE.
Did I mention 83 lumens per Watt?  NEMO outputs 15,000 lumens on a mere 180W of power.

The Seachanger NEMO, from older posts I made about the regular spot and wash units, is also the kind of unit where you attach a Source Four barrel to the device and go.  NEMO is basically an HID source (in output terms) for a Source Four – like the Mole Richardson lamp units for the Source Four.  All of the same filters and xG (extreme green) stuff come with the NEMO.

From the product page:

Say hello to Nemo, the latest in the SeaChanger range designed to deliver a new class of high-intensity lighting.

Nemo is the first ETC Source Four® compatible color engine with a LIFI® plasma source that delivers 15,000 lumens on a modest 180 watts of power. That’s over 6 times the efficiency of comparable color engines.

The SeaChanger Nemo uses existing ETC Source Four front-end barrels as well as an assortment of ETC FOV optics. It comes equipped with SeaChanger’s own Extreme Green wheel that extends the CMY color gamut to create more dramatic, vibrant colors.

Because of its lamp life, Nemo is the perfect solution for hard-to-reach installations, domes, atria and theme parks. It bridges the gap between incandescent and LED lighting at a price that’s within reach.

Go efficient. Go Green. Go Nemo!
