Technology & Product Information



LEDs (Light Emitting Diode) are semiconductor device (electronic component) that emit light when voltage is applied.

The Mechanism of LED Light Emission

An LED is made up of a semiconductor with a structure called a pn junction. When a current is applied, positive charges, or "holes," from the p-type semiconductor and negative charges, or electrons, from the n-type semiconductor begin to move towards each other.
When the positive holes and negative electrons meet at the junction, they neutralize each other's charges. The leftover energy from this process is converted into light energy, causing the LED to emit light.
