I was considering the heat side of things - if i was to buy some of these 8mm 60lumen jobs do you think they'd run a bit hot? after all, my plan is to heatshrink them into the end of the plastic rod. I also noticed that the 40lumen lumiled I purchased that runs at 1watt with its own specific...
for mounting the LED's I've been using some clear fish tank tube with a 5mm internal diameter, just put it in some hot water to make it supple then slip about 10mm over the end of the rod, cut it off with about another 10mm protruding off the end of the rod and the LED slips inside it a treat...
the plastic rod has a 6mm diameter, but my main problem still is if I were to use something like a cree, or a lumiled, or a p4 or whatever the only way for me to feed the output into the rod is to use a fibre optic. I have purchased an end emitting fibre optic (at great cost) which also has a...
I see where you're going with this, but if I file the end of the LED down won't that widen the angle? I thought that if I wanted as much of the emitted light as possible to travel forward I would need a narrower angle? can someone advise me of this?
what about this?

they also sell the spacers too, but they don't sell the light injector lens
looks interesting, silly question but where does it go in the setup? I am absolutely unfamiliar with luxeons & setups - to be honest I'm a total noob! Can you guys post up some ideas for a lightbox/light source? I'd be able to utilise my fibre optic then. Just to clarify, I've got 1metre x6mm...
I think I get what you're saying, but something I forgot to point out is that space is an issue - when I went down the 1watt luxeon lightbox fibreoptic route it's because that's the only way I can feed light generated this way into the end of my plastic rod, what I've been doing with the 5mm...
plastic rod is scored along the back allowing the light to leak out, also it doesn't necessarily have to be 5mm LED, I could probably go up to about 10mm. I know about the luxeon/lumiled throwing more lumens out, but that would mean buying another more powerful LED AND another driver to drive it...
I'm currently in the middle of a lighting project and am new to the LED game - I've read about as much as I can find about LED brightness but it's just not going in anymore!! I am lighting a plastic rod bent into a semi circle using LED's at either end and need to be able to see it in the...
I'm currently building a lighting project for my car and have run into difficulties. I will be passing light through an acrylic rod (similar to the DIY "angel eyes" floating round the web, but not exactly the same) but need them to be visible during the daytime. I have 2x5mm 10,000mcd white LED...
I am currently into a lighting project using leds and have a question.
My project is to pass light through a clear plastic rod that has been bent into various shapes, the idea is to put 1 led at each end of the rod and make the shaped rod light up. I need to be able to see my leds in daytime as...
OK - removed all heatshrink from outside of cell to find surface of cell completely smooth, no bumps, no pcb, no strips nothing. If, as I am being led to believe, this is an unprotected cell then why is it behaving like a protected one? :confused: Its not that it never worked, it did work at...
that's exactly what I thought, but from what I can gather through this thread my blue ones are protected, or are behaving like they're protected, or are just completely borked?
now I'm just confused ..................... :confused:
