UVLED can directly convert electrical energy into UV light, and it emits single-band ultraviolet light. The light energy is highly concentrated in a specific ultraviolet light band. Nowadays, there are mature applications in the market at 365nm and 385nm. , 395nm, 405nm these bands. However, the traditional UV mercury lamp has a very wide emission spectrum, and the UV spectrum that is really effective for curing only occupies a part of it. At the same time, the photoelectric conversion efficiency is low and the energy consumption is large.
Traditional mercury lamps generate infrared rays and emit a lot of heat, which can easily damage heat-sensitive substrates. UVLED is a cold light source, which can effectively prevent the substrate from shrinking and deforming due to overheating, and has a wider adaptability to the material. At the same time, the UVLED used for ultraviolet curing is usually ultraviolet light with a longer wavelength, so no ozone is generated during the curing process, and a good working environment can be maintained. Compared with the traditional mercury lamp, it is safer and more environmentally friendly.
UVLED does not need to be preheated like a mercury lamp, nor does it need to be always on in order to maintain the life and working efficiency of the lamp. UVLED can instantly turn on (off) the lamp, the output energy can also be set freely, and can be automatically adjusted according to the speed of the device, which is very energy-saving and simple and convenient to control.
