Rectangular LEDs, also known as rectangular light-emitting diodes, have become increasingly popular in various industries due to their unique advantages and versatile applications. This article aims to provide a comprehensive introduction to the rectangular LED industry, covering its history, technology, market trends, and future prospects.

History of Rectangular LEDs

The invention of the LED dates back to the 1960s, when Nick Holonyak Jr., a physicist at General Electric, successfully created the first practical LED. Over the years, LED technology has evolved significantly, with rectangular LEDs emerging as a popular choice in the market. The first rectangular LED was developed in the 1980s, and since then, it has been widely used in various applications, such as automotive lighting, street lighting, and display screens.

Technology of Rectangular LEDs

Rectangular LEDs are made of semiconductor materials, typically gallium nitride (GaN) or silicon carbide (SiC), which emit light when an electric current passes through them. The key components of a rectangular LED include the semiconductor chip, the encapsulation material, and the lead frame.

1. Semiconductor Chip: The semiconductor chip is the core of the LED, responsible for converting electrical energy into light. It is typically made of gallium nitride or silicon carbide, which have excellent optoelectronic properties.

2. Encapsulation Material: The encapsulation material serves to protect the semiconductor chip and enhance the light extraction efficiency. Common encapsulation materials include epoxy, polyimide, and phosphor.

3. Lead Frame: The lead frame is used to connect the semiconductor chip to the external circuit. It is usually made of metal, such as copper or aluminum, and provides a stable electrical connection.

The manufacturing process of rectangular LEDs involves several steps, including epitaxy, wafer slicing, chip cutting, and packaging. The epitaxy process involves growing the semiconductor material on a substrate, while wafer slicing involves cutting the wafer into individual chips. Chip cutting and packaging are essential for ensuring the LED’s performance and reliability.
