As an example of this type of discharge lamp, the applicant of the present invention has previously proposed a fluorescent lamp shown in FIG. This is a U-shaped bulb 2 which is open at both ends on a ceramic substrate 1 on which a pair of electrodes 5 are implanted, and a glass frit 4 is attached so that the open ends 21 and 22 cover the electrodes 5, respectively. It has a sealed structure. A phosphor layer 3 is formed on the inner surface of the U-shaped bulb 2, and the inside is evacuated through an exhaust pipe 6 and then a small amount of angon and mercury is sealed therein.

結果塗着作業時間が長くなる問題があつた。 On the other hand, the lamp with the above structure has bulb 2.
The ends are sealed using a glass frit 4 that is fixed to the substrate 1. As for this fixing method, conventionally, glass frit 4 powder and vehicle (nitrified cotton dissolved in isoamyl acetate) were used.
The glass frit paste 4 obtained by mixing the
The two annular concave housing grooves 11, 11 formed at predetermined positions on the substrate surface 12 corresponding to 2 were filled in advance by coating. Note that the grooves 11, 11 are omitted in FIG. Therefore, in order to perform coating using an automatic machine, it is necessary to stop the glass frit 4 from being ejected once one of the grooves 11 has been coated, and then start coating the other groove 11 again. As a result of repeating discharge-stop-discharge, there was a problem that the coating operation time became longer.

くなり塗着作業時間が大巾に短縮できる。 Therefore, the glass frit paste 4 can be applied into the groove 13 by simply discharging the glass frit paste 4 once in a row in a figure 8 shape as shown in FIG. The liquid flows and the necessary coating on the storage groove 13 is obtained. Therefore, compared to the conventional device shown in FIG. 2, although the length of the discharge trajectory is not much different, there is no need to repeat discharge-stop-discharge, and the coating operation time can be greatly shortened.

る。 Furthermore, since the housing groove 13 is shared, only one piece needs to be molded, and the mold for molding the substrate 1 becomes simple.
Furthermore, since the groove 13 is wide and commonly concave between both ends 21 and 22 of the valve 2, there is no need for uneven pressing between these ends when molding the substrate 1, which also simplifies the molding process. You can also improve your abilities.

However, in order to obtain a lamp with higher light output without changing the overall length of the bulb 2, as shown in FIG. It can also be applied to a lamp having a bulb 25 and a second U-shaped bulb 26. In this case, the glass frit accommodating groove 13 is arranged at intervals between the opening ends 21 and 22 of the first and second bulbs 25 and 26, respectively, and between the communication portions 20 of the first U-shaped bulb 25 and the second U-shaped bulb 26. As shown in FIG.
