Arc lantern

Hi lampies a silly question i know, of all lanterns and how they operate,i have one i dont know anything about and that is the old style pressure Arc lamp,i know what a standard electric Arc lamp is and how it works,but know nothing about a liquid fuel arc lantern how it works and why it is called a Arc lantern.
I have seen a few of the in the ref gallery but can find any solid infomation,can any one shed some light on it for me or if i have missed a post regarding can you please show me a link to it many thanks

 

Please post a photo of what you have. "Arc" is a term applied to many different lamps. If you're lucky, it might be a Coleman Arc!

 

Hi Al i have not got a Ark lantern, but have seen and heard of them on here, but no nothing about them and how they work,i was just enquireing about them and how they work

 

Mr Optimus,

I think you misunderstand the word Arc here.
In electric it means spark, which within a lamp also gives light.

But the liquid fuel arc lamp isn't a "sprakling" device. Arc is here more the style of the lamp. And I guess points to the arc shape harp above the burner to mount it to a ceiling.

 

Another explanation I have heard is that at the time the Coleman Arc came on the market, the brightest light around was an electric arc lamp. They probably used the name to say that their lamp was bright.

 

Hi Wim and Nils thank you for the valueble information,i now know why its basicly the style and they work the same as any other pressure lantern

 

Thanks for this great definition of an Arc lamp.

I've been wondering what exactly an Arc lamp (kero/petrol) was and was too afraid to ask

 

Electric arc with a carbon rod was used in large commercial Cinema projectors, Search lights it may be still used.
I too think Coleman used the term to advertise their lamps as very bright,
If an ARK lamp was to be found and there was proof of its connection to Noah I doubt any of us could afford it.

 

Ah but you must never be afraid. There are no dumb questions there are only questions. If you don't know then you must ask. Some of us may have answered the same question a few hundred times but that does not mean everybody knows. Also it does not mean you are dumb for asking. It just means you don't know and asking is in fact the smart thing to do. ::Neil::

 

Thanks for the encouragement Neil.

I generally do try and search the site for an answer before I ask.

I just wasn't sure if Arc was a different system and if it was how it was different.

 

Arc light was use in the old cine machines, like this:



The electric arc light is produced between two carbon electrodes.

 

You can see the two carbon electrodes front the parabolic mirror.

 

I was sent this. I found it very interesting.
