Diffused LED, short for diffused light-emitting diode, is a type of LED with a diffusing layer. It is widely used in various fields such as lighting, display, and communication. In this article, we will introduce the diffused LED industry, including its definition, classification, development history, application fields, market prospects, and challenges.

Definition and Classification of Diffused LED

Diffused LED is a kind of LED with a diffusing layer, which can make the light emitted by the LED more uniform and soft. The diffusing layer is usually made of a transparent or translucent material, such as polycarbonate, acrylic, or glass. According to the diffusing layer, diffused LED can be divided into two types: polycarbonate diffused LED and acrylic diffused LED.

Development History of Diffused LED

The history of diffused LED can be traced back to the 1960s when the first LED was invented. At that time, the light emitted by the LED was very concentrated and had a strong directionality. In order to make the light more suitable for practical applications, researchers began to study the diffusing layer. In the 1970s, the first diffused LED was successfully developed. Since then, diffused LED technology has been continuously optimized and developed, and its application fields have been expanding.
