Description
Technical field
The present invention relates to a kind of modified model microwave ultraviolet ray generation equipment (lamp), this microwave ultraviolet ray generation equipment (lamp) is used in 240nm and replaces mercury to trivalent zirconium ion or the tetravalence lanthanum ion that 270nm has the high emission characteristic, and driven by the electrodeless discharge method, described electrodeless discharge method utilizes microwave electric field to obtain efficient, high-output power and semipermanent durability.
Background technology
Tradition UV generation technique is with the sparking electrode transparent glass tube of packing into, the glass tube of finding time, in glass tube, inject gaseous state mercury, sealed glass tube, discharging current according to the emitting electrons generation that causes by DC electric field or low frequency AC electric field, the mercury vapor that is filled in the glass tube is carried out ionization, thereby send the intrinsic spectrum of mercury, and this intrinsic spectrum is used.
The emission measure of UV ray and the emission spectra that is filled in the ionized gas in the UV lamp are by the type decided of ionized gas, thereby seek and have that broad UV distributes and the material of big emission measure is very important.The spectral line of the monovalence mercury that uses is included in UV, luminous ray and infrared ray (IR) district at present, and has 117 spectrum lines in the scope of 100nm to 2000nm.15000), 435.8335 (brightness: 4000), 365.0518nm (brightness: 2800), 1013.975 (brightness: 2000), 404.6559 (brightness: 1800), 296.7278 (brightness: 1200), 546.0731 (brightness: 1100), 184.950 (brightness: 1000), 256.369 (brightness: 400) and 434.749 (brightness: 400) by the intensity sequence arrangement, spectral line comprises: 253.6536nm (brightness:.Wherein, main UV wavelength is the spectrum of 253.6536nm, and the latter is corresponding to 37.3% of whole spectral intensity.
