Ultraviolet lamp is a device that can emit ultraviolet rays, is a necessary tool to observe the fluorescence and phosphorescence characteristics of samples, and is also a physical means of sterilization. The wavelength is in the range of 10~400nm.
If people's eyes and skin are exposed to ultraviolet rays for more than 3 minutes, it may exceed the human safety limit. After direct irradiation with/kloc-for 0/5 minutes, the cornea will be damaged, resulting in electro-optic ophthalmia, sudden and severe pain in both eyes, foreign body sensation, photophobia, tears or blepharospasm. Long-term radiation can damage eyes and skin, lead to eye trauma and severe skin burns, and may lead to skin cancer.

Use and maintenance
First, the ultraviolet lamp tube must be equipped with ballast, leakage inductance transformer and capacitor in equal quantity before it can be used.
Second, it must be installed according to the wiring diagram provided by the manufacturer.
Three, the installation of light boxes must be equipped with a good air cooling system, to ensure that the lamp tube heat dissipation and the substrate is not deformed by heat.
4. Before using the lamp, be sure to wipe off the handprints and oil stains on the outer wall of the lamp with gauze, otherwise the lamp will crystallize after being ignited. If the volatile solvent content of the UV curing material is high or the working environment is polluted by dust, please wipe the lamp with alcohol every other week to ensure the premature crystallization of the lamp.
Five, the whole use process, should maintain good contact between the lamp holder and the contact point of lamps and lanterns, otherwise it will cause serious oxidation of the lamp holder, leading to the bursting of the lamp seal.
