Understanding the Differences of Deep UV LED

The classification differences of deep ultraviolet LED (UV LED) are as follows:

1) Deep ultraviolet LED can be classified based on their operating wavelength range

Generally, deep ultraviolet light has a wavelength range of 200 to 400 nanometers. Based on the wavelength, deep ultraviolet LED can be divided into short-wavelength UV LED and long-wavelength UV LED. The wavelength of short-wavelength UV LED typically falls between 200 and 280 nanometers, while the wavelength of long-wavelength UV LED typically falls between 280 and 400 nanometers.

2) Deep ultraviolet LED can also be classified based on their materials

Commonly used materials include gallium nitride (GaN) and aluminum gallium nitride (AlGaN). Gallium nitride materials emit light in the range of 380 to 420 nanometers, making them suitable for short-wavelength UV LED lamps. On the other hand, aluminum gallium nitride materials emit light in the range of 250 to 310 nanometers, making them suitable for long-wavelength UV LED lamps.

3) Deep ultraviolet LED can also be classified based on their performance and applications

For example, some deep ultraviolet LEDs have higher light output power and longer lifespan, making them suitable for applications such as UV disinfection and photopolymerization. Other deep ultraviolet LEDs may have shorter lifespans and lower light output power, making them suitable for scientific experiments and specific optoelectronic applications.

It is important to note that different classifications of deep ultraviolet LED may have differences in working principles, light efficiency, lifespan, and price. Therefore, when selecting and using deep ultraviolet LED, it is necessary to make a reasonable choice based on specific application requirements and budget.

4) In summary, deep ultraviolet LED can be classified based on differences in operating wavelength, materials, and performance

Understanding these classification differences is crucial for selecting the appropriate deep ultraviolet LED. In applications, it is important to consider specific needs and budget factors when choosing suitable deep ultraviolet LEDs and ensuring their safe and stable operation.
