5mm Round LEDs: Top Selections & Reviews for LED Lovers

5mm round LEDs have become an integral part of the lighting industry, offering a versatile and efficient solution for various applications. This article aims to provide a comprehensive introduction to the 5mm round LED market, covering its history, technology, applications, market trends, and future prospects.

History of 5mm Round LEDs

The development of 5mm round LEDs dates back to the early 1960s when the first LED was invented by Nick Holonyak Jr. at General Electric. Over the years, LED technology has evolved significantly, and the 5mm round LED has emerged as a popular choice for various applications due to its compact size, high efficiency, and low power consumption.

Technology of 5mm Round LEDs

5mm round LEDs are typically made using a silicon-based semiconductor material, such as gallium nitride (GaN) or aluminum gallium indium phosphide (AlGaInP). These materials emit light when an electric current passes through them. The light emission process occurs within a tiny chip, which is then encapsulated in a transparent epoxy resin to protect it from environmental factors.

The key components of a 5mm round LED include:
1. Semiconductor chip: This is the core component that emits light when an electric current is applied.
2. Lead frame: The lead frame provides electrical connections to the semiconductor chip and acts as a heatsink.
3. Epoxy resin: This material encapsulates the semiconductor chip and lead frame, protecting them from environmental factors.
4. Lens: The lens focuses the emitted light, enhancing its intensity and directionality.
