Infrared High Power LED

night.hoodie said:

idk about the power specs, but here's some info, not sure if it is what you need:

Cree's XLamp XP-E comes in far red:
730nm - 750nm (select VARIATIONS tab to see various XP-E reds)

Osram seems to have the deeper IR spectrum covered:
850nm
940nm

Phillips also apparently has some deep IR LED products:
808nm, 850nm, 940nm and 980nm

The above are high power, high output LED products. The other well known HP/HO LED manufacturers, Nichia, and Lumiled (Luxeon) seem to top out in the near infrared ~700nm, and GE appears to focus on larger bulb-type IR illuminators. If you're looking for 5mm LED in infrared, there must be plenty to choose from since they are so common, but I could not tell you if any meet your power specs.

Hi guys,

I'm not sure if this is the best place to ask this question, but I'm not sure which group was relevant.

I'm looking for a high Power LED in the 80-100w space, near IR spectrum 730-850nm range. LED on board must fit in 49mm diameter. I've seen and have tested some Chinese ones on eBay (see below), though wondering if I can find one from a more credible source.

Can anyone point me to a manufacturer?

Thanks, Damien.

It's not a high volume product so you are unlikely to find much in high power from what we consider reputable suppliers.

That said, currently there is not that much differentiation in near IR LEDs (850nm) and hence the die in those Chinese LEDs could be almost as good as anything else you are going to be putting your hands on. Epistar has one of the best red/IR processes and it could very well be their die. There is a lot more differentiation in white LEDs than there is in IR.

Are you looking to buy lots? You said you tested one. How many do you need?
