Difference of UV LED and UVLED

Low-pressure UV lamps are germicidal lamps that are mainly used for sterilization and disinfection.In addition,UV-B is also mainly used for ultraviolet inspection and medical treatment.
 
The powerful ultraviolet high-pressure mercury lamp is made of high-quality pure quartz tubing, which allows ultraviolet rays to penetrate to a high degree and a large amount. Its arc length/luminous length can range from 5 cm to 300 cm, and the power that is often seen is per unit. Centimeters are 30W to 200W. Ultra-high-power UV lamps generally operate at 200W or more per centimeter. The effective spectral range of this lamp is between 350-450nm and the main peak is 365nm. There are more than 700 varieties, and the power is 100w-25kw. 　UV curing In English, it is called UV Curing or UV Coating. UV curing is a photochemical reaction, that is, liquid UV-curable materials are printed or coated on the surface of the substrate or workpiece, and the curing process is achieved by UV light. UV curing is the same as traditional The drying process is similar, but the principle is different. The traditional drying generally relies on the volatilization of the solvent in the coating material to form hardening, while the UV curing crosslinking does not volatilize the solvent.

The metal halide lamp is based on the mercury UV lamp containing mercury and argon by adding iron blending, potassium blending or other rare earth metal element blending. The iron-blended halogen lamp particularly enhances 380hm as the wave crest. It is mainly suitable for curing of ink and paint, exposure of dry film, wet film, and green solder mask. It is colored in screen printing and curing, especially for products with thicker coatings and white and black drying have excellent results.
 
LED lights are actually commonly known as fluorescent tubes, and the commonly known "light tubes" are actually LED tubes, which are just different in terms of name.
 
Principle of LED tube: Many people are interested in the principle of LED light. In fact, the biggest gap betwPrinciple of LED tube: Many people are interested in the principle of LED light. In fact, the biggest gap between LED lamps and traditional incandescent lamps is the filament. Because the body of the incandescent lamp is transparent, the state of the filament can be directly observed. The LED lamp is different. It uses a diode as the light source of the entire lamp tube. The lamp tube is coated with phosphor. When the diode emits light, the phosphor helps to diffuse the light to achieve the effect of lighting. This is the light-emitting principle of the LED lamp. It is not that a layer of filaments connecting the left and right ends is hidden in the lamp tube.

UVLED,or ultraviolet light-emitting diode, is a kind of LED, with a wavelength range of 260-400nm, which is a single-wavelength invisible light, generally below 400nm. Curing uses mainly 365nm and 395nm. UV glue curing generally uses 365nm wavelength. Through special design, UV LED can emit a complete continuous ultraviolet light band to meet the production needs of edge banding, printing and other fields. The line light source has a long life, cold light source, no heat radiation, life is not affected by the number of opening and closing, high energy, uniform irradiation improves production efficiency, and does not contain toxic substances. It is safer and more environmentally friendly than traditional light sources.
