Hello.
So I'm fitting my bridge out on A model so I'm going to light it up but want to make strip lights rather than a single led bulbs so it's a big spread of light and to make it look live like .Any ideas
Many thanks
Mark

strip led lights from ebay.
a string of leds up to 5 mtrs in length and self adhesive backing.
bends and twists in all directions.
-
Will the lights be seen? Or are you just wanting a full spread of light around the bridge.
How big is the bridge LxWxH? What is the gap between the top of the windows and the ceiling?
-
As I mentioned before 2 No 5 x 2 mm. leds side by side make a good imitation of fluoros in 1:50 scale. For larger scales maybe more of them. Component Shop supplied mine

So I'm building deans marine mv fairwind.
So the bridge is 160mm x 50mm x 40mm
So quite small so I think the string of led s will be to big as I know what you mean .
There on deck as well so would like it for there as well.
There basically fluorescent tube like the 6ft ones.
Brian that sounds good for the bridge.

Just a thought, if you only need a low light effect, rather than full illumination from the tube lighting (although depends on power of lamp); you could try this.
Using fiber optic cable/rod. If you rough up the outside edges of sections of the rod so that it will diffuse light outwards. If you paint the rest of the cable black (followed by a top coat of other color if desired) it can look like the electric cable or conduit that feeds the strip light. You could then run, what looks like, a series of strip lights from one rod. Fixing the rod to wooden slats (mimicking the lamp fitting) would keep the rod straight where it is needed.
I have never done this with fiber optics, but I have used the same roughing techniques on LEDs to make the diffuse light. Perhaps someone with some spare fiber optic rod can try it out and post the results on here.
-
Mmm.yer that could work good idea I will give that a go got so fibre to try it with.
Thanks

Someone else was doing this as well, in that I suggested something similar, someone else also mentioned that some fibre-optic rod emits light out along it body and that triggered the memory of the old light display, as someone went past, the air current made the rods move hypnotically, anyway, some of these rods can be quite thin, try Maplins or maybe a charity shop might have one that can be 'butchered'.
as suggested, a length attached to a strip of base material and painted where not being allowed to emit light (preferably weaving up and down through a base material with the bends painted as the end of the fitting).
-
I am sure I've seen a model type 23 frigate with what looked like tube lighting around the hanger, some kind of help landing lights, but can I find it? Oh no. I'll keep looking
-
I tried fibre optic didn't really work wasn't bright enough. The light sort of stops at the first part that's been filed. It gets dimmer the further along the filed section so back to drawing board

Mark,
Have a look at my HMS QUorn build log. The photo on page 9 showing the crew man on the top deck has the bulkhead fibre optic lights under construction , the lights to the left has not got its lense fitted. The right has . The lense are made for clear plastic rod , drilled to take the fibre, with the top and sides painted. I used 5 x 1.0mm fibres bundle together to one 5mm LED.

A search for 'side light fibre optic cable' produces several hits, this is one

or how about this stuff - not sure if you can shorten it.

you can also solder 3 to 4 1206 smt/leds in a row like I did for my cabin/wheelhouse lights..note I could only do 3 in a series cuz I use 7.4v 6600mha batt...I also used smt/resister chips...the cabins are in the center of the B+ rail...I use magnets and a spring contacter system to run power to the power feed to the wheelhouse roof.. results below

This seller has a LOT of options, see http://www.ebay.co.uk/sch/toby19carolyn/m.html?ssPageName=&_trksid=p2057872.m2749.l2654 (http://www.ebay.co.uk/sch/toby19carolyn/m.html?ssPageName=&_trksid=p2057872.m2749.l2654)
Order to delivery has been only three days on both occasions that I have used them

With optical fiber, the level of light out is always proportional to the light in. The end where the light is shining in needs a bigger light gathering area, this can be done by melting the end into a blob then tamping it on a flat surface, giving a cone shape. The commercially available stuff is usually plastic, rather than glass, so can be melted.
The light level beyond the first outlet area will be reduced, the answer is probably to run individual fibers for each one. A lot of input ends can fit in one ferrule sitting on one light source, even with the ends tamped out.

send me a pm with your email. I have a catalogue of various flood and strip lights ready made from a German supplier. Prices are reasonable and I have bought from him in the past. I can't post it here as its a pdf file and too large to add.
-
Could you put the suppliers website
On here please Brian.
We could download the PDF if needed.
