High Power Infrared LEDs

There are plenty of suppliers who make such a part, but is it a pulsed 1 Watt or a continuous 1 Watt you're after?

What sort of application are you intending to use these devices in... an optical communications LED would need a much higher specification for example than an infrared LED flash etc...

Continuous 1 to 5 watts. I'm looking for an IR LED akin to the visible-light LEDs made by Luxeon. As far as there being "plenty of suppliers who make such a part," may I assume they're all in hiding?

Still looking for you brother, found many suppliers with 5mm but very few with high power, and OS want's your final blueprints to sell you anything.. hahaha

Try OSRAM. If you need directional then use LASER.

You are in a realm where most applications in IR requiring that much power are going to be using laser diodes. These require special drive circuitry as they are very sensitive to overheating. Your choices will be somewhat limited as I'm sure you have discovered.

CW Laser now available high power. Yes, they do require proper driver circuits, minimum current and some watch on the power input to keep the device safe. Pulsing up to few MHz also should be easy task.

However LASER has lower life and LEDs or perhaps OLDs of OSRAM look pretty bright right from Blue to IR range. I also got some from LEDtronix and yet to test them for power. For greater power, greater junction is a much better choice to reduce the damage caused by charge injection. IR LED can survive more than UV LED due to energies involved.

I am having more problem with IR phototransistor as many companies now manufacture poor grade under same catalog number such as TIL99 which was Texas Instrument IR Phototransistor with lens. New packs come in black plastic and some poor quality in somewhat blue-black color. I have to reject 800 such devices which I bought to teach robotics to students. Supply was from my regular supplier. Perhaps no one checks the performance. It was real bad experience.

When you say "single chip" are you seeking the component at the die level or as a packaged part?

Foundry production of "high power" die can be achieved at the expense of yield. If your application will permit, use a packaged component consisting of multiple die with an internal reflector. Suggest that you contact Stocker-Yale, and ROITHNER LASERTECHNIK GmbH as starters.

Try these IR Emitters by Edison-opto. They are available in the USA by IDEA Components. These are the only single-chip, 1W IR emitters inthe style of a Luxeon product that I've been able to find.

IDEA Components usually stocks these parts at engineering sample quantities.

I used them for an experimental cosmetic device and they are quite reliable.

They would also be ideal for a "Night-vision" security camera.
