Diffused LED, short for diffused light-emitting diode, is a type of LED that emits light uniformly in all directions. Compared with traditional LEDs, diffused LEDs have the advantage of soft light, which is more comfortable for the human eye. This article will introduce the industry of diffused LED, including its definition, types, applications, and future development trends.

Definition and Characteristics of Diffused LED

Diffused LED is a kind of LED with a diffusing layer, which can make the light emitted by the LED scatter and spread evenly in all directions. This is achieved by adding a diffusing layer between the LED chip and the lens. The diffusing layer can be made of various materials, such as plastic, glass, or ceramic. The main characteristics of diffused LED are as follows: 1. Soft light: The diffused LED can emit soft light, which is more comfortable for the human eye, reducing the damage to the eyes caused by direct light. 2. Wide viewing angle: The diffused LED can emit light in all directions, with a wide viewing angle, which is suitable for various applications. 3. Good color rendering: The diffused LED can achieve good color rendering, making the image more realistic and vivid. 4. Energy saving and environmental protection: The diffused LED has high luminous efficiency and low power consumption, which is more energy-saving and environmentally friendly.

Types of Diffused LED

According to the diffusing layer material and structure, diffused LED can be divided into the following types: 1. Plastic diffused LED: The diffusing layer is made of plastic materials, such as PMMA, PC, and ABS. This type of diffused LED has good transparency and impact resistance, but its thermal resistance is relatively poor. 2. Glass diffused LED: The diffusing layer is made of glass materials. This type of diffused LED has good thermal resistance and color rendering, but its processing cost is relatively high. 3. Ceramic diffused LED: The diffusing layer is made of ceramic materials. This type of diffused LED has excellent thermal resistance, but its processing technology is relatively complex.

Applications of Diffused LED

Diffused LED has wide application prospects in various fields due to its excellent performance. The main applications include: 1. Lighting: Diffused LED can be used in various lighting applications, such as home lighting, office lighting, and outdoor lighting. It can replace traditional lighting products, such as incandescent lamps, fluorescent lamps, and high-pressure sodium lamps, to achieve energy saving and environmental protection. 2. Display: Diffused LED can be used in display applications, such as digital signage, advertising screens, and electronic monitors. It can achieve high-definition, high-brightness, and wide viewing angle display effects. 3. Industrial control: Diffused LED can be used in industrial control applications, such as signal indication, instrument display, and control panel. It can provide clear and accurate information for operators. 4. Medical field: Diffused LED can be used in medical field applications, such as surgical lighting, examination lighting, and medical equipment display. It can provide soft and clear light for medical staff and patients.
