Rectangular LED, also known as rectangular light-emitting diode, is a type of semiconductor device that emits light when an electric current passes through it. It has been widely used in various fields such as indoor lighting, outdoor advertising, and industrial automation. This article aims to provide an in-depth introduction to the rectangular LED industry, covering its history, technology, market trends, and future prospects.

History of Rectangular LED

The invention of the LED can be traced back to the 1960s, when American physicist Nick Holonyak, Jr. first developed a red LED at General Electric. Since then, the LED industry has undergone rapid development. In the 1970s, Japanese company Nichia Corporation invented the blue LED, which laid the foundation for the full-color LED display industry. In the 1980s and 1990s, LED technology continued to improve, and its application fields expanded. The rectangular LED, as a derivative of the traditional LED, has gradually gained attention in the market.

Technology of Rectangular LED

Rectangular LED is a type of LED with a rectangular shape, which is suitable for various applications such as display screens, lighting, and other electronic products. The main components of rectangular LED include a semiconductor chip, a phosphor coating, and a metal encapsulation. The semiconductor chip is the core part of the LED, which is responsible for emitting light. The phosphor coating can convert the emitted light into a specific color, and the metal encapsulation can protect the internal components from external factors.

At present, the main technologies of rectangular LED include:

• Chip technology: The quality of the chip directly affects the performance of the LED. High-quality chips can ensure the stability and brightness of the LED.
• Phosphor coating technology: Different phosphors can emit different colors of light. The selection of phosphor materials and coating process has a significant impact on the color and brightness of the LED.
• Encapsulation technology: The encapsulation process can protect the internal components of the LED from moisture, heat, and other external factors, ensuring the long-term stability of the LED.
