Pixel LED is a small Lighting unit for both indoor and outdoor decoration.
A LED strip/Module is just a row a LEDs, often with adhesive on one side like tape. Along the strip there are either three or four electrical conductors, depending on the type. Three of these conductors are supply voltage, ground, and data signal. On some types of LED strips, you can also have a clock signal as a fourth conductor.
When a diode is forward-biased so that electrons and holes are zipping back and forth across the junction, they’re constantly combining and wiping one another out. Sooner or later, after an electron moves from the n-type into the p-type silicon, it will combine with a hole and disappear. That makes an atom complete and more stable and it gives off a little burst of energy (a kind of “sigh of relief”) in the form of a tiny “packet” or photon of light.
