Introduction to Diode LED 5mm

The 5mm diode LED, also known as a 5mm LED, is a small, round light-emitting diode that emits light when an electric current passes through it. These LEDs are characterized by their small size, which typically measures around 5mm in diameter. Despite their compact size, 5mm diode LEDs are capable of producing a wide range of colors and brightness levels, making them versatile for various lighting applications.

Characteristics of Diode LED 5mm

The 5mm diode LED is constructed using a semiconductor material, which is doped with impurities to create a p-n junction. When an electric current is applied, electrons and holes recombine at the junction, releasing energy in the form of light. The following are some key characteristics of 5mm diode LEDs:

– Efficiency: 5mm diode LEDs are highly efficient, converting a significant portion of electrical energy into light, with minimal heat generation.
– Color Variety: These LEDs are available in a wide range of colors, including red, green, blue, yellow, and white, among others.
– Brightness: The brightness of a 5mm diode LED is measured in millicandela (mcd) or lumens (lm), with higher values indicating greater brightness.
– Longevity: 5mm diode LEDs have a long lifespan, often exceeding 50,000 hours, depending on the quality of the product and the application.
– Operating Voltage: These LEDs typically operate at low voltages, making them suitable for battery-powered devices and other low-voltage applications.
