UV Mercury Lamp – A Traditional and Effective UV Curing Solution

In the electronics manufacturing industry, especially in PCB processing and protection, curing speed, coating uniformity, and long-term durability are always top priorities. The UV Mercury Lamp is one of the most established UV curing technologies, widely used for many years thanks to its high UV intensity and stable curing performance.

While modern UV LED technologies are developing rapidly, the Mercury Lamp still plays an important role in many production lines, particularly in applications that require wide-area curing and thick UV adhesive or coating layers.

1. What Is a UV Mercury Lamp?

A UV Mercury Lamp is a curing system that uses a high-pressure mercury lamp to emit ultraviolet (UV) radiation across a broad wavelength spectrum. Typical wavelengths include 254 nm, 313 nm, 365 nm, 405 nm, and 436 nm. Thanks to this wide UV spectrum, the system can activate various types of UV adhesives, UV inks, and protective coatings.

When UV adhesive is exposed to UV radiation from a mercury lamp, the photoinitiators inside the adhesive are activated, triggering a polymerization reaction that rapidly cures the surface. This is why Mercury Lamps are widely used in electronics manufacturing, industrial printing, and protective coating applications.

2. Basic Structure of a UV Mercury Lamp

A standard UV Mercury Bulb system typically consists of the following main components:

2.1. UV Mercury Lamp Bulb

• Uses high-pressure mercury

• Emits high-intensity UV radiation

• Wide wavelength spectrum suitable for various UV adhesives

2.2. Reflector Housing

• Focuses and directs UV radiation

• Enhances irradiation efficiency on the curing surface

• Commonly made of aluminum or specialized UV-reflective materials

2.3. Integrated Conveyor System

• Integrated curing chamber or conveyor belt

• Enables continuous UV adhesive curing

• Improves productivity in automated production lines

3. Working Principle of the UV Mercury Lamp

The working principle of a Mercury Lamp is based on exciting mercury vapor inside the lamp using high-voltage electrical current. When energized, the mercury vapor emits UV radiation at multiple wavelengths.

This UV energy directly interacts with the UV adhesive or coating, activating photoinitiators and rapidly forming a hardened polymer structure. With its high UV output, the Mercury Lamp is especially effective for curing thick adhesive layers and large surface areas.

4. Key Features of the UV Mercury Lamp

Compared with other curing technologies, the UV Mercury Bulb offers several distinctive advantages:

• Broad UV spectrum compatible with various adhesives and materials

• High UV intensity suitable for thick coatings

• Effective wide-area curing performance

• Mature, well-established technology

• Easy operation and maintenance

These features explain why the Mercury Lamp remains a preferred solution for many traditional UV curing applications.
