Title: Pulsing the IR Led + LED Lense
Post by: DerTürke86 on May 23, 2008, 04:17:32 AM
Hallo People

i have get some tips from some Friends. They sayed that i could pulse the Ir Led to get more power and when i put an LED lense on the Led it would be much more efektive and i could stand 5 meters from the screen and it would works fine. What would you say about that?
I will try this out and will tell you then the results.

Of course a lens will help - much like the one i tested here from my Laserpointer

Pulsing won't help much.  Which the efficiency of LEDs increases slightly at higher currents, it's not that significant.  Also, for the Wii Remote to track the pulsed LED nicely, you'd need to be pulsing it at at least about 500Hz.

What kind of lense should i use??
I used my pen selfmade on my computer screen but the line is totaly not straid?
And the distance is about 50 cm??
Any way to fix this?
(its a IR led:
s(max) mm: 950
If mA: 100
f: ± 10°)
