IR LEDs

I've been thinking about modding an LED flashlight and hooking it up near the front of the interior. Technically this mod can be for anything night, in this case the little round flashlight doohickie I have does not literally hook up to anything in my car (not via wires aka 12v source). This little mod is to swap the white LEDs currently in this thing and swap them out for infrared LEDs enabling night vision (with the aid of a digital camera). With all the swapping I've done, I've never messed with IR LEDs and I know I'll need resistors, depending on the LED, series/parallel, blah blah blah. That's where I have an issue.

Does anyone know how to work with IR LEDs?
I have 24 IR LEDs I want to solder for 9v (the LEDs are on their way).
Forward volt (typical or IR LED): 1.5
Input voltage: 9 Vdc.
Viewing Angle: 15~30 deg.
Lens color: Water clear
Color: Infrared (IR) 850nm
Luminous intensity (mcd) N/A
Power consumption 60mA


Pics of the light's board (front&back):

FYI: The circuit pic - 3 circuits but different # per circuit. idk how this translates when adding type/no. of resistor(s).

Really?? No one?? Of all the people that handle LEDs, nobody can help me with resistors?
*le sigh*

1st. IR led is same as any LED, but 60ma per LED? (Yikes). I suspect that is max. What is the typical drive current? (if it's 60ma then OK, but that sounds large). But, going with what you have posted. Assuming you want to hook them in series, Simple ohms law.
9/1.5 = 6(led). 6*.06 = 360ma. Voltage/Current = Resistance > So! 9/.36 = 25ohms. Voltage*Current = wattage of resistor > 3.24watts (you should get a 5 watt resistor for a little overhead). this is for one 'circuit'. Total circuit > 24/6 = 4 circuits. Total current draw = 1.44amps.
Note: If your current draw is less, just recalculate using the above example.

a 5 watt resistor?! He can't be pulling that much current. Something doesn't seem right.

let's start with 60mA. I'm assuming these are superflux since regular 3mm or 5mm LED's will burnout.

Input voltage 9V, so 6 LEDs in series with a 1ohm resister. 24 LEDs, so 4 strings of 6.

I agree it doesn't seem right. But that is what he stated (60ma) so I went with that. Maybe I am missing something? He needs to limit current (primarily) to 360ma (per string). How is a 1ohm resistor going to do that?

Also curious on this subject. I would like to find a IR LED strip. I am planning to do this as well except with a backup camera. I want to wire a backup camera to the front and back of the car that i can control with a on off on switch. But I want to ad more IR LEDs to the front so I can possibly have full night vision.

The only IR led I have seen are discreet parts only (no strips). Now I am curious! Have you seen something where the use of IR led works for night vision in cameras? (video or still). That would be neat.

Hi gang, The IR LED's are not going to give you enough "brightness" to use for a back up camera. Unless you string a LOT of them together. For instance the back up camera's you can get from ebay, etc. usually have built in IR's that are no good past 12". IMO.

Iíve got an IR filter for my camera that starts passing at about 750 and peaks at about 880. Iím using this with the 850 nm LightingNext LED strips (which are great). Iím noticing I can still see quite a bit of ambient room light in the camera and am wondering if I should get a filter which peaks closer to 850 to try to cut out some more ambient room light. Iím wondering if this is worth it based on what wavelengths typical room lights put out. If room lights contain a large amount of IR up past the 850 range then it may not be worth changing my filter.
