の傾向が強い。 For example, in a low-pressure mercury vapor discharge lamp used with a power supply voltage of 120V, the lamp voltage during operation is
There is a lighting tube used for starting when the voltage is 65V or higher. In such lighting tubes, active metals such as lanthanum, cerium, barium, etc. are applied or welded to the electrodes to lower the operating voltage. However, in a lighting tube containing such an active metal, if the lamp voltage during operation of the discharge lamp exceeds 70V, the lighting tube may repeatedly restart and become unable to light. This tendency is particularly strong in lighting tubes using barium.

The present invention provides a lighting tube that does not operate again even if the lamp voltage during operation of a low-pressure mercury vapor discharge lamp becomes 70 V or more because the gas is sealed.

5 is a bimetal movable electrode attached to the inner conductor 4 and faces the fixed electrode 3; 6 is barium deposited on the surface of the movable electrode 5; 7 and 8 are attached to the fixed electrode 3 and the movable electrode 5, respectively. These are a pair of lead wires that are connected and extend outside the stem 2. The amount of barium 6 deposited is equivalent to less than 0.6 mg in terms of barium nitride, and the interior of the bulb 1 is mainly composed of neon, with 1 to 10% by volume of argon and some nitrogen. The discharge gas is sealed at a pressure of 40 to 70 Torr.

After mounting the movable electrode 5, the movable electrode 5 is immersed in a barium nitride solution of an appropriate concentration and applied to the surface of the electrode 5.
Thereafter, the stem 2 is sealed to the valve 1, and after evacuation, neon containing 1 to 10% by volume of argon is filled. Then, when aging is performed, barium nitride decomposes and releases nitrogen, leaving barium 6 on the surface of the electrode 5.

あつた。 As mentioned above, in this lighting tube, the amount of barium deposited is less than 0.6mg in terms of barium nitride, so the restart voltage is increased and it can be lit in combination with a fluorescent lamp with a lamp voltage of 70V. I understand.
In addition, if argon was used alone as the filler gas, it would have a short life and be unsuitable, but by mixing 1 to 10% by volume of argon with neon as in this example, it can operate satisfactorily at 120V, making it compatible with lamps. Due to the combination of characteristics, repeated re-operations were eliminated and the result was extremely good.

In Figure 2, the horizontal axis shows the barium deposition amount converted to barium nitride on a relative scale in units of mg, and the vertical axis shows the required lighting time on an evenly spaced scale in seconds.Curve A 1 When the discharge gas filling pressure is 70Torr, curve A2 is also 40Torr.
The characteristic curves for each case are shown. Also, the third
In the figure, the horizontal axis shows the amount of barium deposited on a logarithmic scale in units of mg of barium nitride, and the vertical axis shows the voltage on an evenly spaced scale in units of V.
B 1 is the discharge starting voltage when the discharge gas filling pressure is 70 Torr, curve C 1 is the same re-operation voltage, curve B 2 is the discharge starting voltage when the discharge gas filling pressure is 40 Torr, and curve C 2 is the same re-operating voltage. are shown respectively.

In order to make C 1 and C 2 over 70V, the amount of barium deposited must be 0.6 mg or less in terms of barium nitride, and if there is no barium at all, the discharge starting voltage is 120 V and the operating time is was too long and inappropriate. In addition, the charging pressure of the discharge gas is
Similarly, the operating time will be longer if the temperature is less than 40Torr.
On the other hand, if the sealing pressure was 70 Torr or more, the re-operation voltage would be low, which was inappropriate.

Lighting tubes used in low-pressure mercury vapor discharge lamps with a lamp voltage of 65 V or higher have barium deposited on the electrode surface equivalent to 0.6 mg or less in terms of barium nitride, and the bulb contains mainly neon. Since it is sealed with a discharge gas containing nitrogen, it has the advantage of operating at 120V and being able to be lit even when combined with a fluorescent lamp with a lamp voltage of 70V.
