Abstract
PURPOSE: To permit lighting with a high-pressure mercury vapor lamp stabiliser as well as raise color-rendering property by providing a red-color fluorescent film on the inner wall of outside tube and confining mercury and any one or both of Zn and Cd in specific amounts in a luminous tube.
CONSTITUTION: The luminous film 3 containing a red-color fluorescent substance emitting a light in a wave length range 610nmW630nm is provided on the inner wall of the outside tube 1, and in the luminous tube 4, 0.1W50wt% (based on the total weight of all) any one or both of Zn and Cd in addition to mercury are confined. The amount of mercury to be confined is 0.5W20mg per unit volume (1cc) of the luminous tube 4. Thus, the color rendering property can be raised by the synergistic action of emission spectrum resulting from the vapor discharge of Zn or Cd confined in the luminous tube 4 and the emission of the fluorescent substance and also lighting can be made with the usual type high-pressure mercury vapor lamp stabilizer.
