Everything about LEDs: Basics of High Power LED Lighting

Electronic polarity indicates whether a circuit is symmetric or not. LEDs are diodes, therefore only allowing current to flow in one direction. When there is no current flow, there will be no light. Thankfully this means that if we wire an LED in backwards, it will not burn the whole system up, it just won’t come on. The positive side of the LED is the Anode and the negative side is the ...
