Basic Structure of Cylindrical 10mm LED

Cylindrical 10mm LED is a type of surface mount device (SMD) with a diameter of 10mm and a height of approximately 2mm. It is composed of several key components, including a semiconductor chip, a phosphor layer, a reflective cup, and a lead frame. 1. Semiconductor Chip: The core of the cylindrical 10mm LED is the semiconductor chip, which is typically made of gallium nitride (GaN) or silicon carbide (SiC). The semiconductor material determines the color and brightness of the LED. 2. Phosphor Layer: The phosphor layer is a key component that converts the blue light emitted by the semiconductor chip into white light. Different phosphor materials can produce various colors, such as red, green, blue, and white. 3. Reflective Cup: The reflective cup is designed to enhance the light output of the LED. It reflects the light emitted by the semiconductor chip and phosphor layer, ensuring that the light is directed towards the desired direction. 4. Lead Frame: The lead frame is a metal frame that supports the semiconductor chip, phosphor layer, and reflective cup. It also serves as the electrical connection between the LED and the circuit.

Manufacturing Process of Cylindrical 10mm LED

The manufacturing process of cylindrical 10mm LED involves several steps, including epitaxy, chip fabrication, encapsulation, and testing. 1. Epitaxy: The epitaxy process involves growing a thin layer of semiconductor material on a substrate. This process is crucial for ensuring the quality and performance of the LED. 2. Chip Fabrication: After epitaxy, the semiconductor wafer is diced into individual chips. This process involves cutting the wafer into small pieces, each containing a single LED chip. 3. Encapsulation: The encapsulation process involves coating the chip with a protective material and encapsulating it in a package. This process helps to protect the LED from environmental factors and improve its lifespan. 4. Testing: The final step is testing the LED to ensure its performance meets the required standards. This includes measuring the forward voltage, forward current, and luminous intensity of the LED.
