Introduction to Diode LED 5mm

The 5mm diode LED, also known as a 5mm LED, is a small, round light-emitting diode that measures approximately 5mm in diameter. It is one of the most popular sizes in the LED market due to its size, brightness, and cost-effectiveness. These LEDs are commonly used in indicator lights, displays, and decorative lighting applications.

History of Diode LED 5mm

The history of the diode LED dates back to the early 20th century when the first light-emitting diodes (LEDs) were developed. However, it was not until the late 1960s that the first practical 5mm diode LEDs were introduced by companies like General Electric and Texas Instruments. Since then, the technology has evolved significantly, with improvements in efficiency, color range, and lifespan.

Technology Behind Diode LED 5mm

The 5mm diode LED operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in these LEDs is typically a combination of gallium, arsenide, and phosphide, which allows for the emission of light in a specific color spectrum. The structure of a 5mm diode LED consists of a chip, a lead frame, and a lens. The chip is the core of the LED, where the electroluminescence process occurs. The lead frame provides electrical connections to the chip, and the lens helps to focus the emitted light into a specific direction.
