Rectangular LED, also known as rectangular light-emitting diode, has become an indispensable component in various fields such as lighting, display, and communication. In recent years, with the continuous development of LED technology, rectangular LED has become a hot topic in the industry. This article will introduce the definition, characteristics, application fields, and future development of rectangular LED.

Definition of Rectangular LED

Rectangular LED is a kind of light-emitting diode with a rectangular shape. It is mainly composed of a semiconductor material, a p-type layer, an n-type layer, and a lead frame. When the forward voltage is applied to the p-n junction, electrons and holes recombine, releasing energy in the form of light. Due to its rectangular shape, it has higher light output and better heat dissipation performance compared with traditional round LEDs.

Characteristics of Rectangular LED

1. High light output: The rectangular LED has a larger area of the active layer, which can achieve higher light output than traditional round LEDs. 2. Good heat dissipation: The rectangular shape of the LED can effectively dissipate heat, reducing the risk of overheating and extending the service life of the product. 3. Wide viewing angle: The rectangular LED has a wider viewing angle, which is more suitable for large-area display applications. 4. High brightness: The rectangular LED can achieve higher brightness with the same size, which is more energy-efficient. 5. Long service life: The rectangular LED has a longer service life due to its excellent heat dissipation and stable performance.
