microwave-excited xenon lamp. The plasma temperature is
in the range of 6000K, so it is very bright and very white. It
is quite remarkable that a bulb of approximately 5 mm diameter
and 10 mm length can put out as much light as a 400-watt
metal arc bulb. The color rendering is much better than the
various metal arc lamps. The manufacturer claims that the
efficiency is double that of solid state LED lighting devices.
There probably are some possibilities for using these devices
in several types of spectrometers. I am not endorsing the
company or the technology, but noting that it is very clever.

The Company History
http://www.luxim.com/dynamic/
LUXIM was founded in the year 2000 by technologists in the fields of plasma physics and high-frequency electronics to commercialize breakthrough developments in energy efficient, long-life lighting technology.
After engineering verification and receiving investment funding from Sequoia Capital and Worldview Technology Partners, LUXIM designed, manufactured and commercialized the first series of market leading LIFI solid state plasma lighting products.

the manufacturer politely hints at some corrections:
ReplyDeleteHello,
Thank you for your inquiry. We have characterized our light sources in the 200nm to 2200nm range. Please see the attached chart as an example.
The arc tubes/bulbs are quartz.
In response to some of the other comments in this chain we appreciate the excitement indicated about the capabilities of our technology. The lamps are commercialized in a number of applications already, including some instrumentation light sources used in microscopes and endoscopes. The flicker free performance is valued along with the long life and efficacy in those applications.
The fill gas is Argon. The means of light emission is electrodeless metal halide.
Let us know if you have additional questions.
Regards,
Geoff Brown
