Rectangular LED, also known as rectangular light-emitting diode, has become a significant part of the lighting industry in recent years. With its unique design and superior performance, it has gained popularity among consumers and businesses alike. 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 development of LED technology dates back to the early 20th century. However, it was not until the 1960s that the first practical LED was invented by Nick Holonyak at General Electric. Since then, LED technology has evolved rapidly, with rectangular LED emerging as a popular form factor in the 1990s. The rectangular LED was initially designed to replace traditional incandescent and fluorescent bulbs in various applications. Its rectangular shape offered several advantages over circular LEDs, such as better light distribution and higher efficiency. As the technology matured, rectangular LEDs found their way into various industries, including automotive, medical, and consumer electronics.

Technology of Rectangular LED

Rectangular LEDs are composed of a semiconductor material, typically gallium nitride (GaN) or silicon carbide (SiC), which emits light when an electric current is applied. The semiconductor material is sandwiched between two electrodes, which provide the electrical charge required for light emission. The key factors that determine the performance of a rectangular LED include its color, brightness, and efficiency. Color is determined by the type of semiconductor material used, while brightness and efficiency are influenced by the design of the LED package and the heat management system. In recent years, advancements in LED technology have led to the development of high-efficiency, high-brightness rectangular LEDs. These LEDs are capable of producing a wide range of colors, from warm white to cool white, and are widely used in various lighting applications.
