The uv lamp is what we call the ultraviolet lamp, and uv is its abbreviation, which is the abbreviation of ultraviolet in English. The most commonly seen is used for disinfection in medical treatment. The uv lamp is not only used for disinfection and sterilization, it can also be used for product curing, medical inspection, and according to its characteristics can also carry out photochemical reaction, which shows that it has a wide range of uses.

The fluorescent lamps and energy-saving lamp tubes we see in daily use are made of ordinary glass, and ultraviolet rays cannot be transmitted, and visible light is emitted after being absorbed by the phosphor; while the germicidal lamp tubes are made of ultraviolet transparent glass or quartz glass, which penetrates ultraviolet light. It is transmitted through the glass tube wall.

The commonly used UV lamp in UV curing is arc discharge lamp. During the UV printing process, when the nozzle sprays the UV ink on the surface of the material, the ultraviolet light emitted by the UV lamp reacts with the photosensitive curing agent in the ink, so that the ink can be Dry quickly.

Classification and difference of UV lamps:

According to the different structure of uv lamp, it can be divided into metal halide lamp, mercury vapor lamp, xenon lamp, electrodeless lamp, UV LED lamp.

At present, the mainstream UV curing methods include UV mercury lamp and UV LED light source. Both curing methods are used in the market. The biggest difference is that the UV mercury lamp is a light pipe output, and the UV LED lamp is a direct irradiation head.

Mercury lamp printing equipment generates high heat, is cheap, and has good adhesion, but power consumption and longevity are major issues.

Relatively speaking, UV LED lamps have long lifespan, low power consumption, low heat generation, no mercury, and are cold light sources, and do not generate ozone, are safer, more environmentally friendly, and have good stability.

At present, due to the low cost of UV mercury lamps, it is widely used, and safe and efficient UV LED light sources are gradually occupying the market. In the future, UV curing will mostly adopt new types of UV LED curing, including UV LED point light sources, line light sources, and surface light sources. Mercury lamps and halogen lamps will gradually be eliminated.
