![]() 11, many of the bright lines have peaks in the blue to ultra-violet region, and they do not exist in a red-color region. With respect to spectrums, lights emitted from such ultra-high pressure mercury lamps has several characteristic bright lines which are unique to mercury. In addition, single-plate field sequential image projecting devices use discharging lamps, i.e., ultra-high pressure mercury lamps, as light sources in the projectors because the discharging lights can form a point source of light with high emission intensity. In such single-plate field sequential image projecting devices, the light corresponding to each color, i.e., R, G, and B, is converted by spatial modulating elements, e.g., transmissive LCDs so that the modulated colors represent image information corresponding to R, G, and B during a lighting period, and each of R, G, and B is superimposed over time thus, such a structure enables color display.
