LED Diode 5mm: Superior Quality & Performance at Your Fingertips

LED diode 5mm has become an integral part of the lighting industry due to its compact size, high efficiency, and long lifespan. This article aims to provide an in-depth introduction to the 5mm LED diode, covering its history, technology, applications, and future prospects.

History of LED Diode 5mm

The concept of LED (Light Emitting Diode) was first proposed by Oleg Vladimirovich Losev in 1927, but it wasn’t until the 1960s that the first practical LED was developed by Nick Holonyak Jr. Since then, LED technology has evolved rapidly, and the 5mm LED diode has emerged as a popular choice for various applications due to its compact size and excellent performance.

In the 1970s, Japanese companies such as Nichia Corporation and Sharp Corporation began mass-producing LED chips, which led to the widespread adoption of LED technology in various industries. The 5mm LED diode was introduced in the early 1980s and quickly gained popularity due to its small size and bright, colorful light output.

Technology of LED Diode 5mm

The 5mm LED diode is a type of surface mount device (SMD) with a diameter of 5mm. It consists of a semiconductor chip, a lead frame, and a lens. The semiconductor chip is made of gallium nitride (GaN), gallium arsenide (GaAs), or other semiconductor materials, which emit light when an electric current passes through them.

The lead frame serves as a mounting structure for the semiconductor chip and provides electrical connections. The lens is made of clear or colored plastic and focuses the emitted light into a concentrated beam, enhancing the brightness and visibility of the LED.

The following are some key aspects of the technology behind the 5mm LED diode:

1. Emission Wavelength: The color of the emitted light depends on the emission wavelength of the semiconductor material. Common emission wavelengths include red, green, blue, yellow, and white.

2. Forward Voltage: The forward voltage is the voltage required to turn the LED on. The typical forward voltage for a 5mm LED diode is between 2.0V and 3.2V.

3. Forward Current: The forward current is the current required to operate the LED. The typical forward current for a 5mm LED diode is between 20mA and 30mA.

4. Efficiency: The efficiency of an LED diode is the ratio of the emitted light to the electrical power consumed. Modern 5mm LED diodes can achieve efficiencies of up to 100 lumens per watt.

5. Lifetime: The lifetime of an LED diode is the duration it can operate before its brightness decreases to a specified level. A typical 5mm LED diode has a lifetime of 50,000 to 100,000 hours.
