Technology of 5 mm LED Light

The technology behind 5 mm LED lights is relatively simple yet sophisticated. These lights consist of a semiconductor chip, a lead frame, and a lens. The semiconductor chip emits light when an electric current passes through it. The lead frame provides electrical connections, while the lens focuses the light into a specific direction. The key components of a 5 mm LED light include: 1. Semiconductor Chip: The semiconductor chip is the core component of an LED light. It is made of a material that emits light when an electric current passes through it. The most common materials used in 5 mm LED chips are gallium nitride (GaN), silicon carbide (SiC), and aluminum gallium indium phosphide (AlGaInP). 2. Lead Frame: The lead frame provides electrical connections between the semiconductor chip and the external circuit. It is usually made of metal, such as copper or aluminum. 3. Lens: The lens is used to focus the emitted light into a specific direction. This increases the brightness and efficiency of the LED light. The lens can be made of various materials, such as plastic or glass. 4. Phosphor: In some cases, a phosphor layer is added to the LED chip to change the color of the emitted light. This technology is known as phosphor-converted LED (PC LED).
