Render this: L.E.D lighting

olishea

i think majid's and earthmover's LEDS are most convincing. majid captured that falloff that you get with LEDS...they act like mini spotlights (well the one on my keyring does anyway). So I imagine loading an IES will work well.

OK, this time I modeled a tiny metalic "cone of shame" (he he he) around an even tinier emitter, to better simulate the light source in a LED.

I'm not sure if I like this image better than the previous one:

Different exposure:

EDIT: Added the model with the cone.

Here is mine:
Test Led
Transparent materials - real glass and that's the only correct material here

this is my try.sketchup + KT and also the result is a photoshop combination.
Also you may try it(unzip and load the KT file, attached)

spot light added and lit(MLT, BPT)

no light but sky (MLT, BPT)

combination and adjusted , using photoshop

unzip and then open in KT, cheers

First try

(I know I am a little slower at getting this done than some of you. Actually we found a bug where we were processing curved light emitters too slowly, so this helped fix up the software as well)

Dang. Majid, you beat me to it. I should've checked this thread before building my LED. Oh well, here it is anyway. Feel free to do what you will with it. It's a bit overboard detail-wise, I even threw in a few air inclusions.

I based it on this picture:

A quick try (10 minutes) with Vray for SU first version...

Hi all,
my first post on this forum today!
This is my render of the L.E.D. Lighting:

Ok mate, I tried to keep and respect your level of details, hope you like it (distort correction and a bit of bluring , by PS )

Oh, that is really cool. Nice job. What renderer?

EscapeArtist

Nice job. I used KT as well, gotta work on my materials. Only thing about KT is that it doesn't do volumetric light beams, so I got the same result as you did in your red LEDs; a bright surface light, but nothing "inside" the LED.

OK thanx mate , it is KT as usual, nice that u like it

majid

it does volometric lighting also, but I didn't used

Some nice attempts of rendering LED strip but you wanna try chip leds as opposed to those 5mm. This would be a lot easier..
