 |
|
Ok, so attached is a horribad image of my infrared LED circuit.
The specs of the leds are as follows
Radiant power 16mW min
Output(100 ma) 1.2v
Forward voltage: 100mA
Viewing angle to 1/2 intensity 45 degrees
Wavelength: 940nm
Ok, So I have all 3 leds running with a single 9 volt battery, but they have barely any lighting effect. I'm trying to make a night vision addition to any camera. I can see the bright LEDS when I stare right at them with a camera, but when I say point them to a wall nothing happens.
Any help? What can I do to make the leds brighter?

Wrong section. Should be in "Art".
Back in topic, I don't think a led's light can go that far. Perhaps lasers..? |

Art?
How the fuck does this go in the art section? Really, there is no electronics section, so this is the closest I can get.

It's supposed to be a sort of flashlight.

Well flash doesn't shoot infrared light, and I can't move around with flash recording video.
