• Hey Tom,
  
  I have found these pics for you:

  BTW, you can see how I have scratch built my LOX tunnel hood in this thread (page 7, Rep. 103).
  
  Maybe there is also a drawing in the MLP-1 PDF, if I remember right.

• Hello between years,
  
  so, I once experimented a bit further, with the lighting utensils. Since I had ferrules (probably copper) discovered that could be used for lampshades well.  
  
  These are available in various diameters, with my 2.0 mm (Řa-ferrule) and 2.6 mm (Řa-brim) for the tests initially appeared most suitable, which is the second from the left.
  
  
  
  From this ferrule I have the brim expanded by means of a lathe center and 1-2 light hammer blows on Řa about 3.2 mm (left) and in this picture here.
  
  
  
  And with this "shield" and a pure white LED I have then made a test on the right Access Platform​​, wherein the shaft has to be of course reduced to about 1 mm in length.
  
  
  
  And here with the LED lights again, but the light seems too bright. In fact, it looks indeed still cold white, but is quite bearable. It appears in the photo but still totally garish oversubscribed.
  
  
  
  After that I once tried the small glass beads from the jewelry accessories, first of all the yellow, which I already had. These are about 2.5 mm in diameter (Řa), maybe almost too big for the lamp shade. But I have also seen in Rayher smaller beads.
  
  
  
  The inner diameter of the beads is about 1,0 - 1,5 mm, so that the mini-SMD LED still loose fit through. And this yellow light looks a bit more friendly than the pure white.
  
  
  
  So I've still bought this colorful transparent beads for a color test which with 2,2 mm (Řa) and 0.75 mm (Ři) are somewhat smaller.
  
  
  
  Then I have five pure white LEDs with series resistors hanged to a battery, and the function test without beads also worked right away.
  
  
  
  Now I have five of the colored glass beads slipped carefully over the LEDs, which had the following colors:
  
  1 orange
  2 yellow
  3 red
  4 green
  5 blue
  
  
  
  Here now with lighting, of which the first three patterns certainly seem to me to be suitable, of which No. 1 might have the most pleasant warm tone. Or what do you think?
  
  
  
  Here again for comparison, the first LED without the orange bead with the pure white light.
  
  
  
  And here again the color palette close up.
  
  
  
  And one thing is fact and should be followed. The LED light is in the long run so bright that you really should not look longer into it without protection, what are the manufacturer warns certainly not without reason.

• I am a modeler too ... but a 3D modeler
  
  Can i have a topic in this section ?
  
  I will start the work after unveiling ... in 2014

• Hello and Welcome to NSF Forum!
  
  You have to go back one level to "NSF Space Modeling Forum", where you can start a New Topic. There you also find two 3D topics started by Prober.

• Thanks Manfred !
  
  I am not a newbie ... my account ( Soheil ) is out of service because of technical problems
  
  This is my new account

• Hello folks,
  
  let's come to the end of this very old year and let dim the lights ...
  
  I wish you all
  
  
  
  Take care and stay tuned!

• Hello together in the New Year,
  
  I hope you have all come across well.
  
  I have since made ​​further with the lampshades, or rather, with the ferrules to be what times.
  
  My first hand attempts to widen the ferrule brim with light hammer blows, forget it, as this is too uneven and therefore not satisfactory.
  
  That's why I tried the tip from a modeler from the German Raumcon forum with a cordless screwdriver, and has proven itself just fine!
  
  I have now decided me for ferrules with 1.8mm (Da) and 1.4 mm (Di) that have a brim with 2.4 mm diameter. And the brim I have now, as follows, expanded to a shade diameter of about 3.3 mm.
  
  In addition I have clamped the ferrules over a clamp core (1.4 mm) in my cordless screwdriver, then carefully widened the brim against a vise lathe center at low speed,
  
  
  
  in between was a two time controls the diameter, and finished the lampshade,
  
  
  
  here with the clamp core.
  
  
  
  And these are ever the first 20 lampshades, whose casings must now be reduced only to about 1 mm. 
  
  
  
  Then it went back to the lighting, and this here is a lampshade with orange bead,
  
  
  
  and here at the MLP during light test with the previous LEDs Pure White (0401).
  
  
  
  Since the glass beads towards the bottom are open, some white light still falls through to the bottom.
  
  Meanwhile, I had ordered again SMD LEDs in Sunny white (0603 Micro litz wire) and Golden white (0603 with Cu-wire) that arrived today and of course had to be tested immediately.
  
  The new LEDs No. 4 and 6 (0603: 0.9 mm x 1.6 mm x 0.8 mm) are significantly larger than the previously tested LEDs No. 5 (0401: 1.0 mm x 0.3 mm x 0.5 mm), here already connected for the light test.
  
  
  
  In this test, are now:
  
  2 orange (with bead)
  3 yellow (with bead)
  4 orange (with bead)
  5 pur white (without bead)
  6 sunny white (without bead)
  
  
  
  And the Sunny white actually looks more friendly and warmer than the cold Pure white.
  
  And here's the comparison with the Golden white:
  
  2 yellow (with bead)
  3 orange (with bead)
  4 golden white (without bead)
  5 pur white (without bead)
  6 sunny white (without bead)
  
  
  
  Please do not be confused by the numbering. No. 4, 5 and 6 here considered in a separate comparison, means to me:
  
  The color of Golden white (4) and Sunny white (6) do not differ much, where Golden white (4) is even more expensive and a little bit warmer, but even shorter (about 160 mm) as Sunny white (6).
  
  In any case, both colors for my taste are more pleasant and realistic than the cold Pure white (5), right?
  
  As far as for today.

• So for me personally the warm white light of the Sunny white LED also like quite well. And so here's the quick first test of such a LED in a nreduced lampshade in front of the wall to the right access platform compared to the already known cold light of Pure white LEDs.
  
  
  
  The total overexposure, especially so close to the MLP wall, comes in the photo unfortunately much too crass out what I had described several times.
  
  In the original, this warm white light looks really moderate and fairly realistic and I like it compared to the cold white light under the Blast Shield quite well.
  
  If one now imagines this view with adjusted means of the current bank brightness, that should actually fit quite well. 
  
  
• #396 by shuttlemodeler on 03 Jan, 2014 18:24
• Yes.  That looks a lot better.
• #397 by roma847 on 03 Jan, 2014 21:21
• Yep, but one should be able to photograph the lighting only better that it looks more realistic and not so overexposed.
  
  Whoever can help or has a special tip?
