Bat Wings

[vadeblade]

So, it seems that when making an LED lightsaber, everone is working with Lambertian Luxeon Stars.

Has anyone experimented with Luxeon Stars with a side emitting or batwing beam pattern? Just curious...

I was curious about this too. theledlight.com says the batwings are "low dome" emitters with an almost flat top. Also something I didn't know was that they are used in the Star/O LEDs which some already use for sabers. I don't see any reason they couldn't be used more.

I used both a 3-watt (lambertian) and a star/o (batwing) in my designs & they both worked great. i think the other radiation patterns aren't ideal for making a tight beam. if you look at lumileds' lighting gallery you'll see why...making lightsaber blades is just a tiny fraction of what these LEDs are used for (after making my sabers I wanted to buy a bunch of Luxeons & do some cool stuff to my house with them).

Hey Vadeblade,
I've used both lambertian and batwing star 1's with the LXHL-NX05 lense. I think the batwing helps the lense produce a tighter beam pattern. This means (at least in my experiments) that the blade is more even in it's light distribution. I've decided to use batwings exclusively if I can.

Thanks Madcow. Does the light emission actually look like a batwing?? Just curious why it's called that.

Also, when you build your lightsabers, are you using a colminator or a reflector to focus the light. I am going to make two youngling lightsabers and a lower wattage Lux 1 sounds safer for the young ones. But I don't want to sacrafice too much blade brightness so I would like to reproduce what you are doing.

Thanks,

what are you thinking of on your house mi gin gonn, i am always looking for creative ideas in decorating and have been thinking about putting some LEDs in my office for a controlled light, but havent thought too much about how i want to do it or what i really want to do with it just yet

Vade,
I don't know why they're called batwing... maybe in reference to the "Bat Signal" spotlight???

Most of my experiments have been with the 1 watt Lux stars. You can't get many lux 3 stars in Batwing config.

I use the Collimator lense. I just got a new cheaper version that is sold by luxeon - it boasts a 5 degree beam (as opposed to the 10 degree I've managed with the old lense). so far I have not had time to do the experiment. But I have 3 new Lux 3's to try it with.

Has anyone tried the side emitting one yet?
