UFO … That’s what they’re called, maybe because they are around, maybe because the vendors grew weary of calling them luxeon clones. No, I’m not writing about some errant weather balloon, the planet venus, or my neighbors truck seen through beer goggles… I’m writing about some high-output LEDs
These are the first of any ‘next gen’ leds I’ve worked with … I’m stoked they are so tiny … its often hard to tell the scale when you just see pictures of these things online with nothing of known size in the shot.
the big black module is an RGB ufo, with three one watt emitters in a single package. It’s wired as a common anode device… should work out well with my led controller project. The small led in the top of the picture is a white piranha led. The smaller silver module is a blue UFO.
This is the die of a blue ufo, running at a greatly reduced capacity. I still had to stop my camera all the way down to take this shot with any amount of detail … (1/4000s f7.3)
More pictures to come. I have a red, blue and green mounted to an old 586 heatsink which provides ample cooling to the 3 watt load, I’m going to work on mounting the driver circuitry to the backside of the heatsink and should have some pictures shortly!

So where might one find such a device? come on name names, give up your stockist!
I have just the application waiting for a luxeon clone….

Bob … I purchased these LEDs from Mark Hanna … http://www.moreleds.com
At the time, the deal was exceptional, I paid $3 ea for the UFO … prices have changed in the market, you can get a real Luxeon I for that price or less:

the advantage to the UFO however, is the electrically neutral package, so you can have several on a common heatsink - don’t try that with a real luxeon.

Do you have your LED controller circuit available on the net somewhere, and does it fade from one LED to the next, giving you 7 colours? Would be great for mood lighting or even in the garden!
Thanx,

Andy,
sorry, I don’t have the LED controller published anywhere … the hardware side is pretty simple, just some low side mosfet switches and a microcontroller … the magic is in the software… btw my controller is capable of 30 bit, or 1024^3 colors.
