Revolutionizing Lighting Technology: The Advancements and Applications of Diffused LED

Diffused LED, short for diffused light-emitting diode, is a type of LED that emits light in a uniform and soft manner. Compared with traditional LEDs, diffused LEDs have the advantage of producing less glare and more comfortable light. This article will introduce the diffused LED industry, covering its history, technology, applications, and future development.

History of Diffused LED

The history of diffused LED dates back to the early 1960s when the first LED was invented. At that time, the LED was only used for indicator lights and had not yet been widely used in lighting applications. With the continuous development of LED technology, the diffused LED was born in the late 1980s. In the 1990s, diffused LEDs began to be used in various fields, such as medical equipment, automotive lighting, and display screens.

Technology of Diffused LED

The technology of diffused LED is mainly based on the principle of diffusing light. The diffused LED is made by covering the surface of the LED chip with a diffusing layer. This diffusing layer can be made of materials such as acrylic, polycarbonate, and glass. The diffusing layer can scatter the light emitted by the LED chip in all directions, making the light more uniform and soft.

There are mainly two types of diffusing layers: micro-structured diffusing layer and micro-holographic diffusing layer. The micro-structured diffusing layer is made by molding a diffusing pattern on the surface of the diffusing material. This pattern can scatter the light in a more uniform manner. The micro-holographic diffusing layer is made by recording a holographic pattern on the surface of the diffusing material. This holographic pattern can scatter the light in a more complex and uniform manner.

Applications of Diffused LED

Diffused LEDs have a wide range of applications due to their unique characteristics. The following are some of the main application fields:

1. General lighting: Diffused LEDs are commonly used in home lighting, office lighting, and outdoor lighting. They can provide soft and comfortable lighting, reducing eye fatigue and improving the quality of life.

2. Automotive lighting: Diffused LEDs are widely used in automotive lighting, such as headlights, taillights, and turn signals. They have the advantages of high brightness, long lifespan, and energy saving, which can effectively improve the safety and comfort of driving.

3. Display screens: Diffused LEDs are used in display screens such as LCDs and OLEDs. They can improve the viewing comfort and reduce the visual fatigue caused by glare.

4. Medical equipment: Diffused LEDs are used in medical equipment, such as surgical lamps and endoscopes. They can provide uniform and soft lighting, ensuring the accuracy of medical operations.

5. Industrial lighting: Diffused LEDs are used in industrial lighting, such as workshops and factories. They can provide safe and reliable lighting for industrial production.
