Rectangular LED, also known as rectangular light-emitting diode, has become an indispensable part of modern lighting technology. As a highly efficient and energy-saving lighting source, rectangular LED has been widely used in various fields, such as household lighting, industrial lighting, and outdoor lighting. This article will introduce the industry of rectangular LED, including its development history, product types, application fields, and future prospects.

Development History of Rectangular LED

The development of rectangular LED can be traced back to the 1960s when the first LED was invented. However, at that time, the LED technology was still in its infancy, and the luminous efficiency and stability of the LED were not high enough to meet the requirements of practical applications. With the continuous development of semiconductor technology, the luminous efficiency and stability of rectangular LED have been greatly improved, and its application fields have also been continuously expanded. In the 1980s, the development of rectangular LED technology accelerated. At this time, the LED chip size was further increased, and the luminous efficiency was significantly improved. In the 1990s, the color technology of rectangular LED was further developed, and the full-color rectangular LED was born. The appearance of full-color rectangular LED has greatly promoted the application of rectangular LED in the field of decorative lighting. In the 21st century, with the continuous optimization of the LED chip technology and the improvement of the packaging technology, the luminous efficiency and stability of rectangular LED have reached a new level. At the same time, the application fields of rectangular LED have also been further expanded, from traditional lighting to industrial, agricultural, and medical fields.

Product Types of Rectangular LED

1. Single-color rectangular LED: This type of LED is characterized by a single color, such as red, green, blue, and yellow. It is widely used in indicator lights, display screens, and other fields. 2. Full-color rectangular LED: Full-color rectangular LED can emit red, green, and blue light, and can be mixed to produce various colors. It is widely used in decorative lighting, stage lighting, and other fields. 3.
