Introduction to 3535 UV LED Industry

What is a 3535 UV LED?

A 3535 UV LED, also known as a 3535 ultraviolet light-emitting diode, is a type of semiconductor device that emits ultraviolet (UV) light when an electric current is applied. The “3535” in its name refers to the dimensions of the LED, which are typically 3.5mm in width and 3.5mm in length. These LEDs are widely used in various applications due to their compact size, high efficiency, and stable performance.

Working Principle of 3535 UV LED

The working principle of a 3535 UV LED is based on the semiconductor physics. When an electric current passes through the diode, electrons and holes are recombined at the p-n junction, releasing energy in the form of UV light. The UV light produced has a wavelength range of 10nm to 400nm, which is shorter than visible light and invisible to the naked eye.

Applications of 3535 UV LED

The 3535 UV LED has a wide range of applications due to its unique properties. Some of the key applications include:

1. UV Curing: UV LEDs are extensively used in the curing of inks, adhesives, and coatings. They offer a faster curing speed, lower energy consumption, and a smaller footprint compared to traditional UV lamps.

2. UV Detection and Measurement: These LEDs are used in UV sensors and measurement devices for applications such as environmental monitoring, process control, and security systems.

3. UV Sterilization: UV LEDs are employed in UV sterilization devices for water purification, air purification, and surface disinfection. They are considered a more energy-efficient and environmentally friendly alternative to traditional UV lamps.

4. UV Printing and Marking: In the printing industry, 3535 UV LEDs are used for UV printing and marking of various materials, including plastic, glass, and metal.

5. UV Curing in Adhesives and Inks: UV LEDs are used in the curing of UV adhesives and inks, which are widely used in the electronics, packaging, and automotive industries.
