UVA ultraviolet lamp bead is a special light source element that can emit UVA ultraviolet rays. It has stable UVA ultraviolet light output ability, which ensures that the light intensity and wavelength remain relatively constant during continuous work, and provides reliable ultraviolet light supply for various application scenarios. Ultraviolet lamp beads are small in size and exquisite in design, and can be easily integrated into many different types of equipment and devices, which brings great flexibility to product design. Products are widely used in the fields of fluorescence detection, nail art, curing and medical care.
