As Michael Jackson sang, “Somebody’s Watching Me.” Originally LEDs emitted very little light. They were referred to as light to see, as opposed to light to see by. Fast forward and today LEDs are becoming the lighting technology of choice, as they provide energy efficient light to see by.
Whats next? Possibly, LEDs that see you. While it may not be the LED chip that sees you, the LED light fixture may see you, track you through stores, and message you as “the system” determines. Is this s step to far? Maybe, but that is not up to me. Writing about this, I digress from my typical commentaries on lighting. This is more about the fixture than the light source and the light emitted.
