Which Is Good Traditional UV Mercury Lamp And LED UV Curing Lamp?

Mercury lamps and uv lamps (especially UV LED lamps) have significant differences in several aspects, including the type of light source, wavelength range, energy efficiency and environmental protection.

Here's a breakdown:
1. Type of light source
Mercury lamp: A traditional ultraviolet light source that uses mercury vapor to produce light inside the lamp tube. Its luminous principle depends on the excitation and discharge of mercury.
UV LED lamps: Use semiconductor materials to emit light, with longer service life and smaller volume.

2. Wavelength range
Mercury lamp: A wide wavelength range, usually between 200nm and 400nm, can cover UV-A, UV-B and part of the UV-C wavelength.
UV LED lamps: The wavelength is usually concentrated in a few specific bands, such as 365nm and 395nm, which makes it more targeted in some applications.

3. Energy efficiency and environmental protection
Mercury lamp: The service life is relatively short, about 1,000 to 2,000 hours, and its heat generation is large. In addition, mercury lamps contain harmful mercury components, processing and recycling is more complicated, and the environmental impact is greater.
UV LED lights: Excellent performance in terms of energy efficiency, low power consumption, low heat generation, and a service life of more than 25,000 hours. UV LED lights do not contain mercury and are more environmentally friendly.

4. Light source characteristics
Mercury lamp: emits a long band of ultraviolet light source, in the 350-450nm band has radiation, only part of the energy will be absorbed by UV glue, most of the energy is converted into heat energy, so the equipment power consumption is high, workshop temperature rise is fast.
UV LED lamp: emits a single band of ultraviolet light source, the spectral energy distribution of the UV LED curing machine in the 365nm band is about 365nm, the wave peak fluctuation does not exceed 5nm, and the energy conversion efficiency is high.

5. Application Scenarios
Mercury lamp: Due to its wide wavelength range, it is suitable for a variety of application scenarios, but it needs to pay attention to its high heat and environmental impact.
UV LED lights: In some applications, such as liquid crystal edge sealing, film printing and other occasions that require a small temperature rise, the advantages of UV LED lights are more obvious. In addition, the unit illumination of UV LED lamps is higher, which is suitable for applications requiring good hardening deep13.

6. Service life
Mercury lamp: Service life of about 1,000 to 2,000 hours.
UV LED lamp: Service life of more than 25,000 hours.

7. Start time
Mercury lamps: need to be preheated to achieve optimal working condition3.
UV LED lamp: Instant light, no preheating to achieve 100% power UV output 3.

Disadvantages of using traditional UV mercury lamp:
1, Short life: service life 1200 hours;
2, Power consumption: 4KW/ lamp actual power consumption per hour about 4.5 degrees;
3, Not convenient: long preheating time;
4. Unsafe: high working temperature;
5. Not environmentally friendly: produce a lot of ozone, thermal radiation, mercury pollution.

Advantages of using UVLED:
1. Long life: the service life is 20 times that of traditional mercury lamps, about 20,000-30,000 hours;
2. Power saving: 1kw-1.5kw/ lamp consumes 1.5 degrees of power per hour;
3. Convenient: instant light does not need to preheat the segment point is on and off;
4. Safety: cold light source work, safety and security;
5. Environmental protection: no ozone, no radiation, zero emissions, no pollution, strong support from the government.

In summary, mercury lamps and UV LED lamps have significant differences in many aspects, and the choice of light source should be considered according to the specific application needs and environment.
