As the distance from the internal space increases, the temperature of the luminescent material decreases, and the luminescent material is liable to be liquefied. In particular, when frit glass is buried in a gap between the electrode member inserted into the through hole and the electrode member insertion portion, such a liquefied luminescent substance is applied to the body of the frit glass. The frit seal may be corroded by coming into contact with the portion exposed to the internal space. Such adverse effects are:
This is particularly noticeable when a corrosive luminescent substance is used.

きる。According to the luminous vessel for a high pressure discharge lamp according to the first aspect of the present invention, a portion of the electrode member insertion portion to be inserted into the opening of the body and a portion to be exposed outside the body. And at least one fin is disposed between them. When such a light-emitting container for a high-pressure discharge lamp is used for a high-pressure discharge lamp and frit glass is embedded in a gap between an electrode member inserted into a through hole and an electrode member insertion portion, the discharge space in the body portion is reduced. However, since heat is released from the vicinity of the fins, the temperature near the fins is lower than when no fins are provided. Faster. Since the temperature in the through-hole of the electrode member insertion portion becomes lower as the distance from the inner space of the body increases, the liquefaction of the luminescent material is accelerated in this manner, so that the liquid luminescent material is formed inside the body of the frit glass. It liquefies or solidifies before entering the part exposed to the space. Therefore, it is possible to reduce the adverse effect that the liquefied luminescent material is corroded by contact with the portion of the frit glass exposed to the inner space of the body.

る。According to the present embodiment, the electrode members 2a and 2b used in the high pressure discharge lamp and inserted into the through holes are used.
When frit glass is embedded in the gap between the electrode member insertion portions 3a and 3b, the luminous substance is filled in the discharge space of the body portion 1, but heat is released from the vicinity of the fins 6a and 6b. The temperature near the fins 6a and 6b is lower than when no fins are provided. Therefore, the liquefaction of the luminescent material is faster than in the case where no fin is provided. Since the temperature in the through-holes of the electrode member insertion portions 3a and 3b decreases as the distance from the inner space of the body 1 increases, the liquefaction of the luminescent material is accelerated, so that the luminescent material in a liquid state is frit glass 11a and 11b. Of the body 1 is liquefied or solidified before entering the portion exposed to the internal space of the body 1. The light-emitting substance 12a thus liquefied or solidified
And 12b adhere to the through holes of the electrode member insertion portions 3a and 3b. Therefore, it is possible to eliminate the adverse effect that the liquefied luminescent material enters the portion of the frit glasses 11a and 11b that is exposed in the inner space of the body 1.
