The pedestal flood light

 

Ever wondered what that trapezoid opening in the aft part of the forward overhead is? It is the floodlight for the pedestal. I made a box in which I mounted a 12V LED spotlight. The box is actually made from an old floppy disc box. And I really mean floppy disc! 5 1/4" to be exact! From the old IBM AT era...

I mounted a motherboard standoff inside the box in order to mount the spotlight as close to horizontal as I could - in reference to the cockpit floor. The overhead is appr. 25 degrees from horizontal, so I mounted the light appr. 25 degrees from the bottom of the box. Should work just fine.

There was some light bleeding through the seams, but I fixed that with some liquid tape. That's great stuff!

I used the same stuff to seal the hole where the wires goes through the sidewall of the box.

And then it was time to try! And it worked great!

The only problem I encountered was that all the LED's created their own square of light. *D'OHH* The effect does not look too good, so I'll have to investigate options. Perhaps an opaque thingy? Time will show.

And now: do you see the light?

The overall effect is very good. The only issues are the 19 slightly different light patterns (there are 19 LED's on the spotlight PCB) and that the spotlight looks odd inside the opening. But the concept works, I'll just have to figure out how to solve the issues. Oh, well...
