History of LED 12V SMD

The history of LED 12V SMDs dates back to the 1960s when the first LED was invented by Nick Holonyak Jr. at General Electric. Over the years, LED technology has evolved significantly, with improvements in brightness, color, and efficiency. The introduction of SMD technology in the 1980s further revolutionized the LED industry by enabling the miniaturization of LED components.

Technology of LED 12V SMD

LED 12V SMDs are made of a semiconductor material, typically gallium nitride (GaN) or silicon carbide (SiC), which emits light when an electric current passes through it. The SMD process involves placing the semiconductor material onto a substrate, such as a printed circuit board (PCB), using a high-precision pick-and-place machine. The following are some key aspects of LED 12V SMD technology:

• Material: Gallium nitride (GaN) is the most commonly used material for LED 12V SMDs due to its high thermal conductivity and excellent electrical properties.
• Die Size: The size of the die varies depending on the application, with smaller dies used for high-density applications and larger dies for higher brightness applications.
• Lead Frame: The lead frame is a metal structure that connects the LED die to the PCB, providing electrical connections and heat dissipation.
• Chip-on-Board (COB) Technology: COB technology involves directly attaching the LED die to the PCB, eliminating the need for a lead frame, which results in a more compact and efficient design.
