場合には、安定器からの高圧パルスの減衰周波数が低い
と、紫外線源に流れる電流が小さくなり紫外線放射量が
少なくランプが始動しにくい傾向にある。Although the impedance component is affected by the attenuation frequency of the high-voltage pulse from the ballast, the experiments by the inventors only required that the frequency be 30 kHz or more. In addition, when the pulse voltage is relatively low, such as 1.8 kV to 2.3 kV, if the attenuation frequency of the high-voltage pulse from the ballast is low, the current flowing to the ultraviolet light source becomes small, the amount of ultraviolet radiation is small, and the lamp starts It tends to be difficult.

る。According to experiments, when the pulse voltage is 4 kV,
The lamp lights without any problem when the attenuation frequency is about 3 kHz, but when the pulse voltage is lower than 2.3 kV, the lamp may not light. Assuming a lamp corresponding to a small G12-type base or an E26-type base, an experiment was conducted with a pulse voltage in the range of 1.8 kV to 2.3 kV. As a result, the lamp started when the attenuation frequency was 30 kHz or more. This is considered to be due to the fact that the frequency component increases and the current flowing to the ultraviolet light source increases, and the amount of generated ultraviolet radiation increases.

ためと考えられる。Further, it was considered that the amount of ultraviolet radiation from the ultraviolet source increased when the frequency was increased. However, in experiments, glow was generated in the lamp, but it was difficult to transfer to the arc. This is presumably because, as the frequency decreases, the number of lamps that do not shift to an arc increases because the pulse width decreases.

た。As the discharge lamp, a metal halide lamp (model name) MTS150 / W (model name) manufactured by Toshiba Lighting & Technology Corp. having a double tube structure was used as the ultraviolet light source 2 with the same dimensions as those shown in the above embodiment. With the same configuration, a metal wire made of nickel having an outer diameter of about 0.35 mm is wound around the outer conductive member 25 a predetermined number of times, and a pulser is applied to a ballast 1.5MT (model name, manufactured by Toshiba Lighting & Technology Corporation) using a dedicated pulser. Were tested at a peak voltage of 1.8 kV and a pulse decay frequency of 200 kHz.

用が期待できず好ましくない。[Table 1] As is clear from Table 1, when the capacitance is less than 0.2 pF, the impedance component becomes large, the amount of ultraviolet radiation is small, and it takes a long time to start, and it cannot be expected to function as a starting aid, which is not preferable.

The contact area between the inner conductive member 24 and the outer conductive member 25 of the ultraviolet light source 2 tends to increase, and the generated ultraviolet light tends to be absorbed by the metal, and the radiation amount of the ultraviolet light tends to decrease. In addition, an increase in the number of windings is not preferable because the distance from the opposing potential becomes short, and dielectric breakdown occurs at the opposing potential, so that discharge in the outer tube 3 is likely to occur.

Then, this can be satisfied, and the capacitance is 0.3 to 0.8.
If it is in the range of pF, the starting time can be further reduced, which is preferable.

I do. FIG. 3 is a graph showing a comparison between the number of coil turns (coil diameter is the same) (horizontal axis) and capacitance (pF) (vertical axis) according to the wire outer diameter.

On the other hand, if the number of windings is increased or the wire diameter becomes too large, the passage of ultraviolet rays is undesirably hindered.

If there is no contact property, it is difficult to wind, and if subjected to vibration or shock, the coil-shaped conductive member 25 moves, and in extreme cases, slips out or a gap is formed between the surface of the container 21 and the contact area changes. In some cases, a desired capacitance cannot be obtained.
