One, the main body is different
1, uv mercury lamp: lamp made of quartz glass, with very high power density and effective ultraviolet wavelength.
2, uvled: light-emitting diode with a wavelength of about 400nm of near-ultraviolet light.
2, different characteristics
1, uv mercury lamp: spectral energy distribution from 365nm as the center, between 350NM and 450NM are radiated.
2, uvled: semiconductor materials in the pn junction, the injected minority carriers and majority carriers will be compounded when the excess energy in the form of light will be released, so that the electrical energy is directly converted to light energy.
Three, the scope of application is different
1, uv mercury lamp: applicable to printing plate, ink drying, light curing, polymer compound aging, semiconductor components, such as the production of photochemical fields.
2. uvled: metal cracks, crack detection, photocatalytic light source, banknote counting equipment, anti-counterfeiting industry, and medical measurement and biometrics security detection, hydraulic leak detection and other fields.
