Introduction

What is a 1204 Bi-color LED?

The 1204 bi-color LED, also known as the 1204 dual-color LED, is a type of semiconductor device that emits two different colors of light simultaneously. These LEDs are widely used in various applications, including automotive lighting, decorative lighting, and indicator lights. The 1204 bi-color LED is designed with two separate diodes, each emitting a different color of light. This feature allows the LED to provide a visual indication or decorative effect that cannot be achieved with a single-color LED. The 1204 bi-color LED is named after its package size, which is 1204 in metric units. This package size is also known as the 3mm x 3mm package, which is a standard size for many other types of LEDs. The 1204 bi-color LED is available in various colors, including red and green, red and blue, and red and yellow, among others.

How Does a 1204 Bi-color LED Work?

The 1204 bi-color LED operates based on the principle of electroluminescence. When an electric current is applied to the LED, electrons and holes recombine at the junction of the two diodes, releasing energy in the form of light. Each diode emits a different color of light, depending on the material used in its semiconductor layer. The color of the light emitted by an LED is determined by the energy band gap of the semiconductor material. A smaller energy band gap results in the emission of shorter wavelengths of light, which appear as blue or violet. Conversely, a larger energy band gap results in the emission of longer wavelengths of light, which appear as red or yellow. In the case of the 1204 bi-color LED, each diode is made of a different semiconductor material, allowing it to emit two different colors of light. For example, a red and green 1204 bi-color LED may have one diode made of red phosphide and the other made of green gallium phosphide.

Applications of 1204 Bi-color LEDs

The 1204 bi-color LED is versatile and can be used in a wide range of applications. Some of the most common uses of 1204 bi-color LEDs include: 1.
