In this article, we will introduce the 0805 bi-color LED industry, covering its history, technology, market trends, and future prospects.

History of 0805 Bi-color LED

The 0805 bi-color LED was first developed in the 1990s. At that time, due to the limitations of technology and manufacturing processes, the 0805 bi-color LED was mainly used in low-end consumer electronics products, such as calculators and digital watches. With the continuous advancement of technology, the performance of 0805 bi-color LED has been significantly improved, and its application range has been expanded to various fields, such as automotive, medical, and industrial equipment.

Technology of 0805 Bi-color LED

The 0805 bi-color LED is a type of surface mount device (SMD) LED. It consists of a semiconductor chip, a phosphor layer, and a package. The semiconductor chip is made of gallium nitride (GaN) or silicon carbide (SiC) materials, which can emit light in different colors. The phosphor layer is used to convert the blue light emitted by the semiconductor chip into red, green, or yellow light, thus achieving the bi-color effect. The technology of 0805 bi-color LED mainly includes the following aspects: 1. Semiconductor material: The choice of semiconductor material directly affects the color, brightness, and lifespan of the LED. Currently, GaN and SiC are the most commonly used materials for 0805 bi-color LED. 2. Phosphor layer: The phosphor layer is a key factor in determining the color of the LED. Different phosphor materials can produce different colors, such as red, green, and yellow. 3. Packaging technology: The packaging technology of 0805 bi-color LED is mainly divided into two types: chip-on-board (COB) and chip-on-substrate (COS). COB technology has the advantages of high brightness, low thermal resistance, and compact size, while COS technology has the advantages of low cost and easy processing.
