Guangmai Technology is proffesional in making the UV LED 395nm 405nm 375nm 1W 3W Chip LED diode.
UV LED Defination:
UV LED is a kind of LED, it is a single-wavelength invisible light, generally below 400nm. 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.
UVLED (ultraviolet LED) is composed of one or more InGaN quantum wells sandwiched in a thinner GaN sandwich structure, and the formed active area is a cladding layer. By changing the relative proportion of InN-GaN in the InGaN quantum well, the emission wavelength can be changed from violet light to other light. AlGaN can be used to make cladding and quantum well layers in UVLEDs by changing the AlN ratio, but the efficiency and maturity of these devices are poor. If the active quantum well layer is GaN, in contrast to InGaN or AlGaN alloy, the spectral range of the device emission is 350 to 370 nm.
When a short electron pulse is pumped by the blue InGaN light-emitting diode, ultraviolet radiation is generated. Aluminum-containing nitrides, especially AlGaN and AlGaInN, can make shorter-wavelength devices and obtain series-wavelength UVLEDs. Diodes with wavelengths up to 247nm have been commercialized, LEDs based on aluminum nitride that can emit 210nm ultraviolet radiation have been successfully developed, and UVLEDs in the 250-270nm band are also being vigorously developed.

UV LED advantages for UV curing field
Cold light source, no thermal radiation, low temperature rise on the surface of the illuminated object, solving the long-term thermal damage problem in optical communication and liquid crystal production, especially suitable for occasions requiring small temperature rise such as liquid crystal edge banding and film printing. The heat generation is small, which can solve the problem that the mercury lamp printing equipment heats up and the staff is unbearable. In addition, the LED-UV light source emits high-purity single-band ultraviolet light with almost no infrared output. It is a cold light source, and the processed parts will not be deformed due to heat.
High efficiency: The light energy of LED-UV is highly concentrated in a certain ultraviolet spectrum with effective curing effect. The actual use effect is comparable to the curing effect of traditional high-pressure mercury lamp UV light source with light intensity of 1000～2000mW/cm2, so that The curing time is shortened. The UV light of the traditional mercury lamp looks very bright, but the heat is very high, because its spectrum is very wide, the UV spectrum that is really effective for curing only occupies a part of the energy, and a considerable part of it is in the visible light range (miscellaneous Light) and infrared spectrum (resulting in heat generation), serious damage to the eyes of the operator and easy to thermally deform the processed workpiece.
