LED – Light Emitting Diode LEDs for Beginners in Electronics An LED has a positive lead know as the anode and a negative lead known as the cathode. An LED must be connected in a circuit the right way around – observe the polarity of the LED. The way that the schematic symbol of the LED maps to the physical LED is shown in the diagram below: On the physical LED, the longer lead (or leg) of the LED is the anode. What's inside and LED bulb Teardown explanation The circuit board holding the electronics is two sided and extends back nearly to the foot of the bulb base. The negative lead to the board is held to the metal screw threads by the potting material. Two wires run from the board to the LED board and seem to be hand soldered there. The board itself is reflow soldered.
