Diffused LED, short for diffused light-emitting diode, is a type of LED that emits light in a diffused manner. It is widely used in various fields, such as lighting, display, and medical equipment. In this article, we will introduce the industry of diffused LED, including its development history, technology, market application, and future prospects.
Development History of Diffused LED
The history of diffused LED can be traced back to the early 20th century. In 1907, the British scientist Henry Joseph Round discovered that certain materials could emit light when electric current passes through them. This discovery laid the foundation for the development of diodes. In the 1960s, the LED was born, and with the continuous development of semiconductor technology, diffused LED emerged in the 1980s.
Technology of Diffused LED
Diffused LED technology mainly includes the following aspects:
1. Chip Material: The chip material of diffused LED is mainly GaN, InGaN, and other III-V compound semiconductors. These materials have excellent photoelectric properties, which can effectively improve the luminous efficiency of diffused LED.
2. Chip Structure: The chip structure of diffused LED includes p-type and n-type layers. The p-type layer is responsible for the injection of holes, and the n-type layer is responsible for the injection of electrons. The recombination of holes and electrons generates light.
3. Packaging Technology: Diffused LED packaging technology mainly includes wire bonding, flip-chip, and other methods. These packaging methods can effectively improve the heat dissipation performance and service life of diffused LED.
4. Diffusion Layer: The diffusion layer is a key component of diffused LED. It can make the light emitted by the LED spread evenly, ensuring that the light output is more uniform and soft.
