For a model train layout, I am looking to route a light to a difficult part of the layout - even the 1.6mm LEDs are too big for the area. It is for display, not data communications.
One person has solved the problem on their layout using optical fibre, which seems quite sensible. Rather ingeniously, the light is transferred from an LED the fibre via thimble with a hole drilled in the top.
The fibre does not need to be connected/disconnected from the PCB - a permanent connection is fine.
So, some questions:
- If I have a surface mount LED (or an array thereof), how do I attach an optical fibre to transmit the light for this purpose? I assume there is some sort of plastic mounting I can purchase off-the-shelf.
- What is the attachment called (i.e. does it have a standard name)?
- How are they assembled? (e.g. manual, pick and place?)
- What considerations are there in selecting the type of fibre to use? (it will be no longer than 1m)
(Note to moderators, "optical-fibre" would be a good new tag for this question)
