Technology of LED Diode 5mm

The 5mm LED diode is made up of a semiconductor material, typically gallium nitride (GaN), gallium arsenide (GaAs), or silicon carbide (SiC). When an electric current is applied to the diode, electrons and holes recombine, releasing energy in the form of light. The color of the light emitted depends on the semiconductor material used and the energy band gap of the material. The 5mm LED diode is encased in a clear or colored epoxy lens, which helps to focus the light and protect the diode. The lens can be customized to achieve the desired light distribution and color. The following are some key aspects of the technology behind the 5mm LED diode: 1. Emitter: The emitter is the semiconductor material that emits light when an electric current is applied. The quality of the emitter material significantly affects the performance of the LED. 2. Lead Frame: The lead frame provides electrical connections to the emitter and helps to dissipate heat. 3. Lens: The lens focuses the light emitted by the diode and protects it from damage. 4. Encapsulation: The encapsulation material, typically epoxy, provides mechanical strength and protects the internal components from environmental factors.
