Technology of 8mm Yellow LED

The 8mm yellow LED is a type of surface-mounted device (SMD) LED. It is made of a yellow phosphor material that emits light when an electric current passes through it. The yellow phosphor material is typically a mixture of zinc sulfide and cadmium sulfide. The technology behind the 8mm yellow LED involves several key components: 1. Chip: The LED chip is the core component of the 8mm yellow LED. It is made of gallium nitride (GaN) or gallium arsenide (GaAs) and is doped with indium to create a p-n junction. 2. Phosphor layer: The phosphor layer is responsible for converting the blue light emitted by the LED chip into yellow light. It is typically made of a mixture of zinc sulfide and cadmium sulfide. 3. Substrate: The substrate is the base material on which the LED chip and phosphor layer are mounted. It is usually made of aluminum nitride (AlN) or sapphire. 4. Lead frame: The lead frame is a metal frame that connects the LED chip to the external circuit. It is typically made of copper or aluminum.
