Workings of a Lantern

[jim_holg8]

Hello,

 

Im trying to compile a list of usful technical theatre terms and the working of things, The only thing I cant find really is the do's and dont of lanterns and how detailed drawings, I could do them myself but I would prefer if they are on the net to just print them out

 

Thanks again, If anyone could help that would be great,

 

J

'Fraid I'm not really sure what you're asking for. Dos and don'ts of lanterns? What sort of thing do you mean? Do plug it in if you want it to work? Don't lick the lamp when it's been on at full for three hours?

 

Detailed drawings of what? Do you mean things like cutaway drawings of lanterns showing the optical path, etc.?

 

Sorry, but you're going to have to be clearer, and a bit more specific, with your question.

Is this work for a project or exam piece?

On the net there are already countless glossaries of theatre and technical terms (US and UK terms differ by the way) so Google "theatre terms glossary) and see what it comes up with.

 

It terms on do's and don'ts for lanterns - I'm standing next to Gareth on this one - be more specific with your question.

[T.D.]

Regarding diragrams - I'm guessing you're looking for 'exploded diagrams' which show how to take appart and re-assemble lanterns whilst serviceing them (hopefully so as to avoid the 'now why's that bit left over' syndrome)

 

For most modern lanterns the best bet would be to contact the manufacturer. Certainly Clay Paky and High End do them for their lights, and I think Strand do for their generics - I image most manufacturers do.

 

There is also a site devoted to old Strand lanterns (pat 123's etc) which I think had exploded diagrams for them but I don't remember the site addr - another job for google me thinks.

 

Regarding optical path mentioned by gareth, you'll probably find this in a lot of the 'stage craft/stage lighting' type books

 

In terms of do's and don'ts, I dont think that's as stupid as it sounds

Do have them pat tested regularly

Do close the shutters on profifes when not hung so as not to bend them

Don't get the shutters wet - they seize and rust

Do safety bond barn doors and other accessories (and the fixture for that matter)

...all sounds noddy, but if you're new to and have nobody to show you, how would you know?

 

Any way, there's a few for starters. Hope this is of some help

That would be the strand archive at www.strandarchive.co.uk for which google finds 8 references in the blue room alone

 

1) 7-in. diameter faceted ellipsoidal reflector

2) Medium prefocus lampholder

3) 7-in. diameter annular reflector

4) Gate runners for beam-shaping mask or optional addition of an iris or purpose-made mask

5) Fixed aperture diaphragm to intercept stray light; also position for second 3½ x 5-in. lens for Patt 23W

6) 3½ x 5'in. lens for Patt 23, or 3½ x 4'in. Fresnel lens for Patt 23F, in sliding lens tube provided with safety chain

7) Double colour frame runners

8) Hinged rear door for interior access

And lest we forget, the Stagelink site has a whole bucketful of lighting links (and more besides).

Jim (first post) your a little vague so I don't know how easy this is for you!

 

Get a job/work experience at your local Stagecraft in the Lighting department (or hire company which acculy looks after their gear)

 

I did it for a bit, and after a week of cleaning and striping all the various different lights your knowledge is far sharper...

 

I worked on all the departments, which was quite interesting... (coiling 25m 3 phase power cables! to replacing the optics units in Mac500's)
