Introduction to 3mm Multi-Color LED

The 3mm multi-color LED is a type of light-emitting diode (LED) that emits light in a range of colors, including red, green, blue, and yellow. It is designed with a diameter of 3mm, making it one of the smallest LEDs available in the market. This compact size allows it to be used in a wide range of applications, from consumer electronics to industrial lighting. The 3mm multi-color LED operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in these LEDs is typically a combination of gallium nitride (GaN), aluminum gallium nitride (AlGaN), and indium gallium nitride (InGaN). These materials enable the LEDs to emit light in different colors by adjusting the composition and thickness of the layers.
