Introduction to the 0805 Bi-color LED Industry

What is a 0805 Bi-color LED?

The 0805 bi-color LED is a type of light-emitting diode (LED) that emits two different colors of light from a single package. This compact and versatile component is widely used in various applications, including indicator lights, displays, and decorative lighting. The 0805 bi-color LED is named after its physical dimensions, which measure 0.08 inches by 0.05 inches, making it one of the smallest SMD (Surface Mount Device) LEDs available on the market.

Design and Structure

The 0805 bi-color LED is designed with a single chip that contains two separate diodes, each emitting a different color of light. These diodes are usually placed side by side within the package, allowing them to emit light in two distinct colors simultaneously. The two most common color combinations for 0805 bi-color LEDs are red and green, and red and blue. The structure of a 0805 bi-color LED typically consists of the following components: 1. Chip: The chip contains the two separate diodes, each with its own phosphor coating to emit light in a specific color. 2. Lead frame: The lead frame provides electrical connections between the chip and the external circuit. 3. Bond wires: The bond wires connect the chip to the lead frame, allowing the LED to conduct electricity. 4. Package: The package encloses the chip, lead frame, and bond wires, protecting the LED from external elements and ensuring proper heat dissipation.
