Abstract

PURPOSE:To control mercury vapor pressure within a proper range by providing an amalgam formation material on the side end part of a base. CONSTITUTION:An amalgam formation material 24 is provided inside a stem 23 at an end part on the base side of a luminous tube 30. By said material 24, a mercury vapor pressure level is controlled within proper range even when a temperature of the end part on the base side of the tube 30 rises by heat due to a lighting device when lighting under the base. As a result, lowering of a light flux and an excessive temperature rise of a stabilizer due to an increased lamp current can be prevented.

2. Description of the Related Art Recently, various compact fluorescent lamps have been put into practical use as energy-saving light sources in place of incandescent light bulbs. FIG. 3 shows a typical single-capped fluorescent lamp. The arc tube 1 has four straight glass tubes 2 to 5 connected in series to form one discharge path through three bridge parts 6 to 8, and electrodes 9 and 10 are connected to each of the bridge parts 6 to 8. It is set up. Also,
A phosphor film 11 is formed on the inner surface of the arc tube 1, and a rare gas such as mercury and argon is heated at 3 to 4 Torr.
It is enclosed. Further, a cap 12 is provided at the end of the arc tube 1 on the electrode side.

The above lamp structure is characterized by the tips 13 of the glass tubes 2 to 5.
By separating the tips 13 to 16 from the discharge path with a bridge structure, the coldest spots are formed at the tips 13 to 16 when the cap is lit.

On the other hand, when the top of the cap is lit, the temperature of the tips 13 to 16 rises, so the coldest point is formed at the cap side ends 17 and 18 of the glass tubes 3 and 4 or the exhaust pipe 19. The temperature at the coldest point controls the mercury vapor pressure within an appropriate range.

Problems to be Solved by the Invention The single-cap fluorescent lamp shown in Figure 3 is assembled as a single lamp, but it can also be lit inside the case by combining the luminous tube, a case for supporting it, and a light bulb base. Lamps with built-in devices are also being considered. However, in such a lamp, the temperature at the end of the arc tube on the base side increases due to power loss in the lighting circuit, so it is impossible to provide the coldest point in this part.

In other words, when lighting above the cap, the tip of the arc tube becomes the coldest point and the mercury vapor pressure is controlled within an appropriate range, but when lighting below the cap, the coldest point cannot be formed properly, causing the mercury vapor pressure to rise excessively. do. As a result, when lighting under the cap, the luminous flux is lower than when lighting above the cap, and the lamp current becomes higher, causing problems such as an excessive rise in ballast temperature.

Means for Solving the Problems In order to solve these problems, the single-capped fluorescent lamp of the present invention connects adjacent ends of a plurality of glass tubes, and A case made of cap material is attached to one end of the arc tube, which has a phosphor film formed on its inner surface, electrodes provided at both ends, and mercury and rare gas sealed inside, and a lighting device is placed inside this case. It has a structure in which an amalgam-forming substance is provided at the end of the arc tube on the base side.

By providing an amalgam-forming substance at the end of the arc tube on the cap side, even if the temperature at the end of the arc tube on the cap side rises excessively due to power loss in the lighting circuit during lighting under the cap, the amalgam-forming substance will not be removed. Since the mercury vapor pressure is lower than that of mercury alone, the vapor pressure level can be controlled within an appropriate range.
