Chip SMD LED, also known as Chip-on-Substrate LED, is a type of light-emitting diode (LED) that has gained significant popularity in recent years due to its numerous advantages. This article will provide an in-depth introduction to the chip smd led industry, covering its history, applications, technology, market trends, and future prospects.

History of Chip SMD LED

The concept of Chip SMD LED originated from the traditional LED packaging technology. In the early 2000s, as the LED industry rapidly developed, the traditional packaging method began to show its limitations. The traditional packaging method involves bonding the LED chip to a lead frame, which is then mounted on a circuit board. This method not only increases the cost but also reduces the efficiency and brightness of the LED. To address these issues, researchers and engineers began to explore new packaging technologies, leading to the birth of Chip SMD LED.
