Specific Properties of Mercury Arc Lamps

Lamp Types M200 U1 PS M200 U1 Power Density = 120Wcm [Pg.83]

Artificial radiant sources are characterized by their power density (i.e. the input power per unit length in W cm ), the efficiency of conversion of electrical energy into photon energy (radiant power efficiency r =i) in a defined wavelength [Pg.83]

Typical emission spectra of two different LP and a MP mercury lamp are presented in Figs. 4-5 and 4-6. The 50 W LP mercury lamp (Heraeus, NN 50/81, Fig. [Pg.84]
