Introduction to 1204 SMD LED

What is a 1204 SMD LED?

The 1204 SMD LED, also known as the 1204 surface-mounted device light-emitting diode, is a compact and highly efficient lighting component that has gained significant popularity in the electronics industry. With its small size and versatile applications, the 1204 SMD LED has become a staple in various lighting solutions, from household appliances to industrial equipment. A 1204 SMD LED is a type of LED that measures 1.2mm in diameter and 0.4mm in height, making it one of the smallest available on the market. Despite its diminutive size, it offers impressive brightness and color options, making it a preferred choice for designers and engineers looking to integrate high-performance lighting into their products.

How Does a 1204 SMD LED Work?

The 1204 SMD LED operates on the principle of electroluminescence, which involves the emission of light when an electric current passes through a semiconductor material. When current is applied to the LED, electrons and holes recombine at the junction between the P-type and N-type layers of the semiconductor, releasing energy in the form of photons. The 1204 SMD LED is constructed using a phosphor coating that converts the LED's blue light into a broader spectrum, producing various colors such as red, green, blue, white, and amber. This phosphor coating is applied to the top of the LED, which is typically made of a sapphire or silicon chip, and is then mounted on a substrate.
