[Industrial Field of Application] The present invention relates to a krypton-containing incandescent light bulb that improves the characteristics of the light bulb. [Prior Art] Conventional incandescent light bulbs were generally filled with only nitrogen gas or with a mixture of nitrogen and argon, but recently, incandescent light bulbs with a mixture of nitrogen and crimpton or nitrogen, A krypton light bulb filled with a mixed gas of krypton and argon has been developed and put into practical use. [Problems to be solved by the invention] Although this krypton light bulb has the excellent characteristics of being small, highly efficient, and has a relatively long lifespan, on the other hand, krypton is about 600 to 800 times more expensive than argon, so the above-mentioned problems arise. A gas mixture of krypton, nitrogen, and other gases is sealed in a light bulb. However, such conventional krypton-filled light bulbs have a drawback in that the inner wall of the light bulb darkens quickly. Therefore, the inventor of the present invention investigated the cause of this blackening as follows. In other words, in conventional lamps, a zirconium getter is coated as a getter on the support, and this getter absorbs impurity gas when it reaches about 800 degrees Celsius, but in bulbs filled with argon, nitrogen, or only nitrogen, There is a fact that after the getter interacts with impure gas in the early stage of lighting, there is almost no getter action thereafter. This is thought to be due to nitrogen interfering with the function of the phlegm. On the other hand, krypton is usually traded by being filled in iron cylinders like nitrogen and argon, and the oxygen concentration is highly pure at 3 ppm or less at the time of filling, but after 2000 hours it drops to around 20 ppm. This is presumably because oxygen becomes a gas and mixes into the krypton when the iron on the inner surface of the cylinder is oxidized. Therefore, if such krypton is sealed together with nitrogen or the like in a light bulb and turned on, it is thought that the oxygen mixed in the krypton will have an effect, and the filament will generate impure gases such as oxides from the support etc. It would be preferable if such impure gas could be sorbed by a getter, but since the getter is obstructed by nitrogen as described above, it cannot be sorbed, and therefore the inner wall of the light bulb rapidly turns black. [Means for Solving the Problems] In view of the drawbacks of the prior art as described above, the inventor of the present invention provides an incandescent light bulb containing krypton that prevents the inner wall of the light bulb from turning black and has a long life. As a result of intensive research with the aim of
Moreover, he realized that it was only necessary to fill in a small amount of hydrogen, and completed the present invention.The structure of the incandescent light bulb is to fill the bulb with krypton and argon. , is characterized in that 3×10 -8 to 6×10 -7 g atoms are enclosed per 1 c.c. of the inner volume of the tube. [Function] Since the present invention does not fill the bulb with nitrogen, the function of the getter does not deteriorate. Also, since a trace amount of hydrogen gas is sealed, the homing effect of hydrogen prevents the deterioration of the supports inside the bulb. can be prevented. [Example] The inventor of the present invention used a valve with a diameter of 35 mm,
In addition to removing oxides adhering to the pillars inside the bulb, reduce the vacuum inside the bulb to 10 -3 to 10 -4 mmHg.
After setting the amount of krypton sealed to the valve volume 1
4.5 x 10 -7 g molecules to 1.2 x 10 -5 g molecules per cc, hydrogen from 3 x 10 -8 g atoms to 6 x 10 -7 g atoms per c.c., and argon within the range of 300 mm to 500 mm Hg. In addition to prototyping a large number of light bulbs sealed with
The experiment was conducted under power consumption of 60W and current of 0.56A. As a result, a krypton-containing light bulb filled with a small amount of hydrogen gas without using nitrogen gas is able to prevent the deterioration of the pillars inside the bulb due to the homing effect of hydrogen, allowing the highly pure krypton gas and argon gas to be mixed together. Since the filament circulates within the bulb, there is less evaporated material from the filament adhering to the strut and the inner wall of the bulb, reducing blackening and significantly extending the service life. This is naturally due to the fact that the function of the getter does not deteriorate due to nitrogen gas. In addition, the inclusion of hydrogen gas effectively prevented arc breakage. It is assumed that the effect of the inclusion of hydrogen gas is probably based on the reducing action of hydrogen on the metal surface. Furthermore, it was found that the arc voltage of the krypton-containing light bulb according to the present invention manufactured within the above-mentioned range of the type and amount of filler gas exceeds 180V,
It was also found that the surface temperature of the light bulb only rose by about 180 to 190 degrees Celsius, which was about 40 to 50 degrees Celsius lower than a conventional light bulb filled with a mixture of 50% argon and 50% nitrogen gas. In other words, the non-nitrogen-filled light bulb according to the present invention has less heat loss, and if the amount of nitrogen contained in the filled gas is large, the surface temperature of the light bulb will rise. It can be seen that it is preferable that the gas does not contain nitrogen gas. Furthermore, as a result of the above-mentioned prototype production and experiments, hydrogen gas also causes an increase in the surface temperature of the light bulb when it is contained in an amount of 1.5 x 10 -6 g atoms or more per 1 c.c. of the bulb volume.
Since it has been found that this causes a decrease in efficiency, it is desirable that the amount of the substance enclosed be within the above range. [Effects of the Invention] As described above, the light bulb according to the present invention filled with a mixture of three gases of argon, krypton, and hydrogen within the above-mentioned range is different from the conventional mixture of krypton and nitrogen, or a mixture of three gases of argon, krypton, and nitrogen. Higher quality and longer lifespan than bulbs with sealed bulbs. Here, the high quality and long life were achieved because we were able to effectively prevent the blackening of the inner walls of the light bulbs and the deterioration of the pillars, etc., and the light bulbs of the present invention and the conventional light bulbs had the same brightness. Compared to conventional products, the lifespan of the light bulb of the present invention is 2.
This means that it will expand by about twice as long. Incidentally, the results of a comparison between a conventional lamp and a light bulb filled with a mixed gas of argon, krypton, and hydrogen according to the present invention under the same conditions will be described. In other words, when there is no blackening on the pillar and there is less blackening on the bulb......〇 When there is blackening and there is no difference from conventional lamps......
× The blackening of the bulb will be reduced, but if blackening adheres to the pillar etc. from an early stage......△

[Table] As can be seen from the table above, only in lamps filled with hydrogen without filling with Chitsuso, the pillars, etc. do not darken during the entire movement, and the progress of blackening on the entire lamp is slow (it is said that the pillars, etc. do not blacken). (This means that the blackening of the lamp as a whole is slow.) Also, the same effect was observed with argon and hydrogen, but in this case the arc voltage was 150V, and for krypton, argon, and hydrogen it was 180V, so this It can be seen that the composition is the best for an incandescent light bulb. As described above, the present invention is a light bulb that uses expensive krypton, but it is a high-quality, long-life incandescent light bulb that has high utility value. By enclosing the krypton inside, it is possible to improve the rise in surface temperature of the bulb and the decrease in efficiency while preventing arc breakage, making it extremely useful as an incandescent light bulb containing krypton.
