    Light Pipe - LED Effects - messing around

    Ok i was bored decided to play around with optics of acrylic tubes to see if I can use 1 LED to create nice light affect for various parts in the car, here are few pix. I wasn't really stultified, was expecting better results.

    my rough experience with light tubes, and acrylic--most designs i have come across use at least 2 leds-- one at each end, to help with light dispersion.

    the other cool thing that i like to see is that some designs will frost/roughen the back of the acrylic-- so the visible part is still crystal clear, but the frosted/roughed up part catches the light, and sends it out..

    Ye if i put 2ND led on other side it will look much better still light does not go to far, well maybe ruby lens will increase the distance but then we not building lasers here

    I tried scratching only back part that was not much difference but adding chrome plate on the back projected light much better...

    I think straight high power led scrip we build is much better then rod

    definitely.



    i used some smd-type plcc2 strips in my trunk for accent lighting-- way brighter then any plexi/acrylic solutions

    as you said, you can make some very cool visible effects, but most of them are only visible in a dark room.. put it in a bright room, or in sunlight, and i have never seen a lightpipe beat a raw led..

    one of the things i have been meaning to experiment with though is using a frosted/roughted-up acrylic sheet to aid in light dispersion to create a smoother, broader light.. kind of a hybrid of a lightpipe/ raw led solution..

    well dam thing about LED strip they are dots Under the bright sum my headlight leds SMD3xxx look like small dots even though each led gives me 200LM thats as bright as it gets comparing to ebay stips that have like 30LM per led

    by the way we are building 16 zone RGB strip and led controller to control lights in the car, like under body, door light, headlights, interior and 16 zone trigers - u open door door light light up w/ selected effect. Will work as standlone configurable device and will have USB so you can control any lighs the way you want with CarPC

    very cool!

    i have been meaning to order some flexible rgb strips, but the brightness, and cost puts me off..

    in case you decide to look for a different solution, i found this usb rgb controller a while back:

    Why not line it with EL tape? Will give a perfectly even glow. It's how they do it with most concept cars at the car shows.

    Drill out / hollow out the acrylic tube, then coat with clear nail polish, this will get it clear again. Slip the led in the hollowed tube. Wrap end with foil tape. No light wil escape the tube except for where you want it to...
