1, ultraviolet mercury lamp: the lamp tube is made of timely glass, with extremely high power density and effective ultraviolet wavelength.

2.uvled: A light-emitting diode with a wavelength of about 400nm near ultraviolet light.

Second, the characteristics are different.

1, ultraviolet mercury lamp: the spectral energy distribution is centered at 365nm, and there is radiation between 350 nm and 450 nm.

2.uvled: In the pn junction of semiconductor materials, when the injected minority carriers recombine with the majority carriers, the excess energy will be released in the form of light, thus directly converting electric energy into light energy.

Third, the scope of application is different

1, ultraviolet mercury lamp: suitable for printing and plate making, ink drying, light curing, polymer compound aging, semiconductor device manufacturing and other photochemical fields.

2.uvled: metal cracks and crack detection, photocatalyst light source, banknote inspection and counting equipment, anti-counterfeiting industry, medical metrology and biometric security detection, hydraulic leak detection and other fields.
