new purple idea

[Luar Selbor]

Has anyone tried to put two Lux III's one blue/or cyan and one red in a saber?

[Eandori]

More then 1 LED in a single saber is really difficult. Not just the mounting of the LED... that is easy. The hard part is getting an optic lens that focuses the light from both LED's at 5 degree emission out the emitter on the saber.

There is no room inside a saber for 2 full size stars and lenses, even if there was, they don't both point directly down the saber tube.

Short of having a VERY EXPENSIVE lens created for you that focuses light from two luxeons down a single 5 degree shaft, it won't work very well with our current part supply.

You can use a RGB led and use the red and blue to make purple, all you need is a single optic because all three colors are in one led

[Steeljack]

There's always the Lamina RGB Atlas (http://www.laminaceramics.com/docs/AtlasDatasheet.pdf), if its voltage requirements don't scare you, and you don't mind paying for a green emitter you're going to wind up not using...

:D

I've played around with Lamina Atlases (white and RGB) before, and wasn't terribly impressed.

If you want RGB, a Rebel Moon is the best way to go right now.

I was thinking of buying two of these

and put them on my oun star that I would make.

and use a 8 AAA battery pack for the power suply.

But how would you focus the light? The problem isn't the LEDs, it is the optics.

[Luar Selbor]

It doesn't gather the light that is under it.

[Ghostbat]

If I were to attempt this i think what I would do is mount them to a slightly concave surface then run them into a lens... actually a prism would probably be ideal but fiddly... so the light came together before being focused.

This isn't optically ideal but might work well enough for the purpose.

Pure theory of course :)

You could get a lense like in flashlights. open the bottm a bit to accept the 2 emitters but really the best options is to have doclo make you a custom purple.

Or a p4 with a purple filter or a grb led with only 2 leds on.

About the only options to get a purple.

[Luar Selbor]

what if you put two lensess in it

one up side down and one right side up

like a hourglass

so the light would be focused

[Hasid Lafre]

Wont have enought space.

I think in this case one lens would focus the light and the second would defocus, end result right back where you started minus whatever light was lost in the process (IE better off with no lens at all)

While using two LEDs might be possible you will probably be better off with a single RGB star where the hard work has already been done for you and the elements are much smaller and closer together.

[Hasid Lafre]

Yeah, if ya want a true purple that you can dial in, a rgb led with 2 pots will be the ticket. I think tim can get pots with the buck pucks.

BTW, what happened to the lenses for the Rebel Endor that was rumored a while ago. I can find pics of them on www.led-tech.de, but not for sale.

[Soulkeeper7700]

i hear the closest way to get purple right now would be the ultraviolet star, but i have yet to see it in person, but they are pretty cheap. has anyone tried it or has any pics/vids of it?? would love to see!

[Hasid Lafre]

I havent seen this uv star yet so I cant make any comments on it.

[Hasid Lafre]

Darth L the link dont work.

[Luar Selbor]

What about using four 1 wats? Put them around the optics. Maybe even five of them.

[LAN-ED-TUL]

what bout the purple saber Do-Clo made? huh?

[Hasid Lafre]

He just mounted 4 or 5 uv purple leds to a heatsink.
