Need help: Fiber Optics and light blocking
« on: May 29, 2018, 10:26:49 am »
So Im working in a 1400 Enterprise D (a wip post may soon follow), and with my nacelles I'm using 1mm fiber optics to light aft strobes. My problem is, they are picking uo a lot of blue light absorption. I don't normally work with fiber optics, so my question is, is there anything i can do to prevent them from picking up the ambient light without adding a lot of mass (like shrink wrapping) so it doesnt cause an unsightly shadow.

Thanks!

Hi

Could swapping the FO out for suitably sized SMD's be an option for you?
I am sure someone with experience in this kit will be along with an answer for.

I've considered that, but I was looking for a specific diameter and didnt want the light flush - with a fiber optic i could flare it amd give a nice bulb effect at the right diameter.

I guess I could just mount it flush and us the fiber just for the top but that also would require 4 bulbs insteas of the planned 2 and more resisters etc. M I just don't like that idea as much. Ideally if i can light block the fibers someway whather paint or a better product thats how I would wamt to go.

I use black tulip paint and coat the fiber with it from where it goes through
the nacelle or hull all the way back to the led.

Could you tape the fibre to the inside of the narcell, black insulation tape would provide some light blocking.

You can get Black Tulip on Amazon, or Michaels, or I think Hobby Lobby.

https://smile.amazon.com/Tulip-41401-Dimensional-Fabric-Paint/dp/B004BQ01CQ/ref=sr_1_30?ie=UTF8&qid=1527625622&sr=8-30&keywords=black+tulip

That would probably be the easiest.  Another option that should (SHOULD) still give you the "bulb" effect is to use the aforementioned SMD, and then a slightly extra dollip of Krystal clear.  I think you can get a a nice rounded bulb effect (both physically and with the light effect).

..but I don't see an issue with the tulip/FO technique if you're more comfotable with that.

Good luck and let us know how it goes!

Cheers!

Just to add to simi's post. I've seen tulip paint just about everywhere. Even my local Walmart carries it.

So i picked some up.... Question is now, what's the best way to paint them? Open up the bottle and dip them in? Paint one side at a time?

I just tip the bottle over and squeeze it out along the fiber after you have it in place.
It has a super fine tip so it is not that hard.
