With the rapid development of the lighting industry, 3mm bi-color LED has emerged as a popular choice for various applications. This compact and versatile lighting solution offers the ability to produce two different colors from a single LED, making it highly sought after in fields such as signage, display, and decorative lighting. In this article, we will delve into the details of 3mm bi-color LED, exploring its features, applications, and the market trends surrounding this innovative technology.
Introduction to 3mm Bi-color LED
The 3mm bi-color LED is a type of surface mount device (SMD) that emits light in two distinct colors. Typically, these LEDs are available in red and green, but other color combinations, such as blue and red, or white and red, can also be produced. The small size of the 3mm bi-color LED allows for high-density packaging, making it ideal for applications where space is limited.
These LEDs are constructed using a semiconductor material, such as gallium nitride (GaN) or gallium arsenide (GaAs), which emits light when an electric current passes through it. The bi-color capability is achieved by incorporating two separate LED dies within the same package, each emitting a different color. This dual-color feature is made possible through the use of color filters that selectively pass light of the desired color.
