Abstract

PURPOSE:To realize the safety and a long service life by making the enclosing wt.ratio of NaI and ScI3 and the enclosing amount of them in a specific scope of value respectively, and giving a specific relation between the height of a heat insulating layer at the lower side of a luminous tube from a luminous tube sealing end and the length of a projection of the electrode in the luminous tube. CONSTITUTION:The enclosing wt.ratio R of NaI and ScI3 is made 3<=R<=7, and the total enclosing amount of NaI and ScI3 per 1cc of the luminous tube volume, Mmg/cc is made 0.1<=M<=0.5. And when the height of a heat insulating layer 7 at the lower end side of the luminous tube 4 from the luminous tube sealing end 5Ba is made Hmm, and the length of a projection of the electrode in the luminous tube 4 is made lmm, they are set to satisfy 1/4l<=H<=3/4l. When such a composition of lamp is held to make the posture of the luminous tube 4 almost vertical and lighted, no shaking of arc is generated at the relative color temperature 4700K, and the luminous efficiency 1001m/W, for example, and the damage of the luminous tube can be prevented, as well as a stable property is obtained. Thereby, a safe and a long service life of metal haloid lamp can be obtained.

Taking advantage of its high efficiency and high brightness characteristics, in recent years it has begun to be widely used as a fishing light for squid fishing in place of incandescent light bulbs. By the way, 1. For example, in the case of the above-mentioned fish-collecting lamps, metal halide lamps of TIA degree were used at first, but later lamps with higher output were used, and now 2KW lamps are the mainstream, and even more recently, 344KW lamps have become mainstream. Ogi's rung has been developed and is beginning to be used. Unlike the JL interior lighting, these fishing lights are used naked and suspended on the boat (with the luminous tube in a vertical position), and the light color of the lamp is also based on the experience of fishermen.
Since it is said that a tube with a diameter of 5,000 to 5,000 yen is good at attracting fish, those using sodium iodide and scandium iodide as the filler for two arc tubes are widely used.

The inner diameter of the arc tube must be 25 mm or more, and the distance between the electrode tips must be 150 mm or more. However, in lamps with three or more lamps, arc fluctuations occur centered around the bottom end of the single arc tube, which causes the light color and luminous flux to change synchronously, and in some cases, the high temperature that causes fluctuations. The arc abnormally approaches the quartz glass, which is the material of the arc tube, and this sometimes causes problems such as excessive heating of the quartz glass and damage to the quartz glass.

5 causes arc fluctuation. Furthermore, if the height H (m) of the heat insulating layer is set to H x 1/41, the heat insulating effect will be insufficient and the temperature of the coldest part at the bottom of the arc tube will drop, resulting in a decrease in luminous efficiency. The light color will exceed 5000K. On the other hand, when H>4/3J, the luminous efficiency is good, but it is not acceptable because it causes arc fluctuation.
