Have you ever noticed just how many LED lights are on in your house? It’s really something else. In my house there have to be hundreds, possibly thousands. TV’s, computers, printers, radios, alarm clocks, routers, chargers, VCR’s, DVD’s, amps, pedals, power strips, kitchen appliances, other appliances, etc, etc, etc. All of them blinking or changing red to green over and over. From where I am sitting right now I can count over two dozen that are on.
It’s really amazing and well it makes me feel old. I remember the first digital watches and handheld video games that were a big deal. Like the Mattel Electronics football II game (the green one). I still have mine someplace. I spent hours playing that thing.
Talk about the way back machine. It reminds me of the first flashlight I ever made. My dad tossed out a strand of Christmas lights. I took them apart, stripped the wires and connected them directly to a little 9 volt battery. I bet that future flashaholic was eight years old at most.
I’ve thought about this question before. I have some LED bulbs, each with four 1W LEDs. That’s 50 or so. If you include flashlights, that’s another 50 or so. If you include electronics, it’s tough to count them, but I’d guess 100 or more. That puts me in 200+ LED territory.
Oh, I forgot the LED work lights I built using high power modules; should I count each emitter spot in the modules?
The page shows a closeup view of a giant LED panel, similar to a Sony Jumbotron or Lighthouse R7. “LED TVs” don’t actually include one LED per pixel: they’re made up of an LED backlight plus an LCD panel.
I assume most cellphone screens, too, are made up of an LED or fluorescent backlight plus an LCD panel.
