New class of lightbulb

**Hi all,

this news caught me by surprise today:

http://www.gizmodo.com.au/2014/07/this-super-efficient-lightbulb-uses-tesla-tech-for-an-incandescent-glow/

A bunch of Yanks (called "Finally Light Bulb ) have produced an affordable,
miniature size "induction lamp" for home use.

http://en.wikipedia.org/wiki/Electrodeless_lamp#Magnetic_induction_lamps

Identical in shape and appearance to the now banned light GLS bulbs with
lumen /watt efficiency and colour quality similar to CFLs.

Instant start and no loss of life if cycled regularly as there are NO
filaments to burn out.

Omni-directional light output - unlike most CFLs and LED lamps.

Can be safely handled and installed using the glass bulb - unlike fragile
CFLs.

800lumen ( 60W equivalent) set to go one sale this month in the USA.

Higher rated versions on the way, being made in India.

First to post a review / tear down on U-tube will get millions of hits.

an interesting read Phil.

Will be able to use old incandescent globe (glass) manufacturing machines.

as usual, I'm sure the price will drop with production.

Cheers Don...

**Interesting. It reminds me of a light I read about several years ago
(but have hear nothing since), where a sodium vapour is excited by a
microwave source. Sodium offers the highest efficiency of any of the
metal vapours, but at the expense of a narrow light spectrum. The fact
it was driven by a microwave source and the lack of a 'white' light,
limited it's usefulness, I guess. Efficiency was very high though. Much
higher than standard HID lamps.

I think you may mean sulphur, not sodium. There was an article by Julian
Edgar in Silicon Chip December 1999 (page 82) on microwave sulphur lamps
in a series on electric lighting technology.
http://archive.siliconchip.com.au/cms/A_103351/article.html
The technology saves energy in the long run, but is probably too
expensive up front to sell to average consumers.

Interesting, but I wonder whether they can compete with current LED
technology. 100+ lumens per watt is now pretty common, DC operation at
low voltage, compared with induction spraying RF everywhere at several
MHz. An EMC nightmare, paricularly at the cost driven consumer end of
the market.

I also wonder about the lifetime. I thought the life of a
mercury/phosphor lamp was limited by degradation of the phosphor by the
mercury ions accelerated to high speeds in the tube. LEDs dont suffer
from that, although I have to admit that the lifetimes for LEDs quoted
are far longer that the technology has been around.

**Actually, most 'white' LEDs operate in a similar fashion. They employ
a blue LED with a yellow phosphor coating. I've been using white LEDs
since they first became cheaply available. I still have some of the
originals. Their light output has degraded significantly (they operate
24/7).

Just a variation to the popular "tl"tube but with a radiosignal instead of
current through the gas.
The same thing can be done by keeping the tl tube next to a radiating
antenna..
The lightcolour is purely dependant to the chemicals in the coating as the
light produced in the gas is uv.

Yes I read the Wiki.

But maybe its time to start thinking about the fact that LEDs ( and
maybe these induction lamps ) are not in the same class as our old
tungsten lamps, and designs built around having them replaceable by the
average consumer.

At the typical lifetimes quoted, like 50-100K hours, they are going to
last as long as the average house under normal domestic use. And so you
can afford to put them in with decent heatsinking for the LEDs, and so
get the full life potential.

Did that for my own amusement in my house, converted CFL fitted mushroom
lamps to LEDs, fitted onto good heatsinks and with temp switches on fans
for hot weather. Work great. Been running at least in the office at 10
hours per day for the last 3 years, and no problems. CFLs were lasting
12 months if I was lucky in the same useage.

Which is really useful, Not. A quick perusal of the article indicates it
was about getting the electronics down to a size to fit into a consumer
standard x type light socket.

I hope they eventually make them with a higher colour temperature. I
really don't like yellow lighting any more.
