Revolutionize Lighting with 5mm Round LEDs – Your Ultimate Guide

5mm round LEDs, also known as 5mm diameter round light-emitting diodes, have become a popular choice in the lighting industry due to their versatility and efficiency. This article aims to provide a comprehensive introduction to the 5mm round LED market, covering its history, technology, applications, and future trends.

History of 5mm Round LEDs

The concept of the light-emitting diode (LED) was first proposed by Oleg Vladimirovich Losev in 1927. However, it wasn’t until the 1960s that LEDs started to gain attention in the industry. The 5mm round LED, as we know it today, was introduced in the 1970s. Over the years, advancements in LED technology have led to improvements in brightness, color, and efficiency, making them a preferred choice for various applications.

Technology of 5mm Round LEDs

5mm round LEDs are typically made of semiconductor materials, such as gallium nitride (GaN), gallium arsenide (GaAs), and silicon carbide (SiC). These materials emit light when an electric current passes through them. The LED’s structure consists of a p-n junction, where the p-type and n-type semiconductor materials meet. When electrons and holes recombine at the junction, they release energy in the form of light.

The color of the emitted light depends on the energy band gap of the semiconductor material. For instance, GaN emits blue light, while GaAs emits red light. To achieve white light, a combination of red, green, and blue LEDs is often used. The efficiency of the LED is determined by the material’s ability to convert electrical energy into light, known as the light efficiency. Higher light efficiency translates to better energy savings and lower power consumption.
