Light-emitting diodes are more commonly used, and the positive and negative electrodes are easy to distinguish. The long pin is positive and the short pin is negative.

LEDs emit light when forward biased, and when voltage is applied across the junction to forward bias it, current flows as if it were in the case of any PN junction.

From the image above, we can observe that N-type silicon is red and includes electrons represented by black circles.

Different LED compounds emit light in specific areas of the visible spectrum and therefore produce different levels of intensity.

To produce visible light, the PN junction must be optimized and the correct material must be selected.
