Technology

The 5mm Multi-Color LED Diode is a semiconductor device that emits light when an electric current passes through it. The diode consists of a cathode, anode, and a phosphor layer. The cathode and anode are made of different materials, which create a p-n junction. When an electric current is applied, electrons and holes recombine at the p-n junction, releasing energy in the form of light. The color of the emitted light depends on the energy band gap of the semiconductor material used in the diode. Different materials, such as gallium nitride (GaN), aluminum gallium indium phosphide (AlGaInP), and aluminum gallium arsenide (AlGaAs), emit light in different colors. The phosphor layer is used to convert the emitted light into the desired color. The 5mm Multi-Color LED Diode is available in various packages, such as the 5mm round package, 5mm square package, and 5mm chip-on-board (COB) package. The round package is the most common, while the square package offers better heat dissipation and the COB package provides a compact and seamless design.
