History of 4mm Multi-Color LED Diode

The concept of multi-color LED technology dates back to the early 1960s when Nick Holonyak Jr., an electrical engineer at General Electric, successfully created the first practical red LED. Over the years, advancements in semiconductor technology led to the development of green and blue LEDs. The combination of these colors allowed for the creation of white light, marking a significant milestone in the evolution of LED technology. The 4mm Multi-Color LED Diode gained popularity in the late 1990s and early 2000s, primarily due to its small size, low power consumption, and ability to emit multiple colors. This innovation paved the way for a wide range of applications, including architectural lighting, automotive lighting, and consumer electronics.

Technology Behind 4mm Multi-Color LED Diode

The 4mm Multi-Color LED Diode operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. These diodes are typically made of gallium nitride (GaN), gallium arsenide (GaAs), or indium gallium nitride (InGaN) substrates, which are capable of emitting light in different colors when excited by an electric current. The color of the emitted light is determined by the energy band gap of the semiconductor material. For instance, a GaN-based LED can emit blue light, while an InGaN-based LED can emit green or red light. To achieve multi-color emission, these diodes are often encapsulated in a phosphor coating that converts the emitted light into a desired color spectrum.
