History of Power LED SMDs

The development of power LED SMDs dates back to the 1960s when the first LEDs were invented. However, it was not until the late 1990s that power LEDs started to gain traction in the market. The advancements in semiconductor technology, particularly in the development of high-efficiency gallium nitride (GaN) and silicon carbide (SiC) materials, played a crucial role in the growth of the power LED SMD market.

Technology of Power LED SMDs

Power LED SMDs are based on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The key components of a power LED SMD include the semiconductor chip, the encapsulant, and the lead frame.

The semiconductor chip is the core of the LED, where the light is generated. It is typically made of gallium nitride or silicon carbide, which have high thermal conductivity and can withstand high temperatures. The encapsulant is a transparent material that protects the semiconductor chip and helps to dissipate heat. The lead frame is a metal frame that provides electrical connections to the semiconductor chip.
