Definitions

  • the present invention is directed to the improvement of incipient mercury incipient specificity of incipient luminous flux which occurs during the firing of a cantilever fluorescent lamp having a spiral light emission tube.
  • incandescent bulbs have been downsized to the size of normal incandescent light bulbs, and the demand for the replacement of the light source in ordinary incandescent bulbs with incandescent fluorescent bulbs continues.
  • the mercury at initial power up after lamp completion is unevenly distributed near where the original source of mercury has been applied; when switched on, the temperature of the light-emitting tube of the lamp rises, the mercury spreads according to this temperature distribution, and uniformity increases. There was the problem that, at this initial turn-on, due to the unequal distribution of the mercury in the light-emitting tube, differences in luminance occurred, and there were lighter parts and darker parts.

  • the single capped fluorescent lamp having a helical light emission tube based on the present invention is characterized in that the second mercury outflow source is a Zn-Hg alloy.
  • the single capped fluorescent lamp having a helical light emission tube based on the present invention is characterized in that the second source of mercury is formed so that a porous medium, which is composed of at least one of the materials silica, alumina, titanium oxide or iron as the main constituent, mercury is added.
  • the mercury outflow source is divided into the first mercury outflow source and the second mercury outflow source, the unequal distribution of the mercury is mitigated.
