Induction/Electrodeless lamps

I tried to re-invent this wheel a number of years ago,

by modifying conventional fluorescent tubes to add end foils, so that

they could be run on RF HV in an attempt to eliminate the need for filaments.

It was a dismal failure, as

the cold cathode fall caused the Hg in the lamp

to be sputtered into the glass wall / phosphor

Within a couple of hundred hours, their efficiency dropped to unusability.

This might have to be mitigated in the induction lamps as well.

Since the induction lamps also use RF,

emissions approval is a major headache.

Considering the cheap chinese CFL's now on the market,

for the same price as a pack of incandescents,

it doesnt make a lot of market sense to go up against this behemoth.

The cost per life is the same, while energy use is way down.

The new white LED technology stands a better chance, but

will have a long hard climb.

Ultimately, i would put my money on the LEDs.

Ive developed an LED based product powered by induction but it only has use as a current sensor rather than a device to produce light in volume.

It can detect currents > 0.25-500 Amperes from a single pass through a simple current transformer. If the current transformer is eliminated and the device placed in circuit it will produce a bi-coloured light signal over the range of 0.003 to 10 Amperes. The Bi colour LED also has 2 optocouplers in series giving volt-free outputs to a data system that resolve the presence and polarity of a current over this massive range.

It has to be the simplest device available for the purpose of getting information straight to the eye and to a machine as it is line-powered and only needs to fitting into a circuit. Just imagine being able to see even intermittent faults

That's very good docrobgar, I'm sure you will find many uses for that.

We know of a person who has the technology to produce the induction/electrodeless lamps/ballast at a fraction of the cost the majors incur, and he can DIM it easily while all others claim No dimming feature on their Induction lamps.. Oh well, that doesn't surprise me, when all the HPS experts said you CANNOT dim HPS lamps, my engineer designed the Dimming Sodium that works perfectly, and will dim down to 5%, and allows the arc tube to instant re-strike, similiar to the Electrodeless technology!

I LOVE IT, when people say, "You cannot do that".... ha

Can I have the name and adress of the person, who has the technology of producing Induction lamps and ballasts with dimming application. You can send it to rrao@litetronics.com

Yes, right, I will get that right over to you...
