Yet another LED Fixture

[derekleffew]

So the tour I'm working right now has about 80 of these, Ayrton 150 moduLED, built into the set under clear Lexan as footlights. They're great. One of the neatest features, is there are no buttons. Below each of the standard labels: Menu, enter, up, down; are photocells on the front of the fixture, for setting mode and address.

I'm sure these are expensive units, but seem very well made and with very good output.

I'm sort of fuzzy on photo cells, how does this work?

I've always wanted a fixture that could create "snumbers of rich and saturated colour-hues."

Well, obviously they didn't have me writing their cutsheet. If I did the conversion properly, these fixtures list at $2600 US. Yikes! But not that far off from CKs or Pixelines.

AVkid, a photocell, or "electric eye," acts as a button press when you hold your finger over the little circle where the button would be. Kind of a gimmick on these fixtures, but no moving parts or micro-switches to fail.

Kind of like my motion sensing fixture on the outside of the garage.
I see now.

Avkid they are only the same if your motion sensor is of the sort where you have to walk through a beam to set if off. It is more like the door way alarms you sometimes see in shops to let them know a customer has come in. There will normally be a little box one side of the doorway and something like a bike reflector on the other to bounce the light beam back to the dector. They work by detecting when the light beam is broken.

Motion sensor used for outside lights and burglar alarm are different and use things like Infrared detectors to detect body heat. There was a segment on Myth Busters where they tried to full the alram sensors with all sorts of methods such as cooling the person, putting them in relective foil etc.

Derek on these LED fixtures what do they use as a light source for the detector?

Yep, when you place a finger over the sensor on the LED fixture, Phil's garage opens!

I would think these sensors would have both a small IR emitting and IR receiving LED. (Think TV remote > TV). When your finger covers the hole, the IR emitting LED is bouncing light back to the IR receiving LED. That's my guess.

Go to sleep Charlie, your comments are bordering on ridiculous.
