1st positioning element 17 in the way of through hole 13c adjoinings by with being arranged in the cylindrical portion 13a of Lighthead assembly 13
Side.By shrinking the 1st positioning element 17 in the state of lead 14 is passed through into the 1st positioning element 17, so that the 1st location division
Part 17 is engaged with the state across covering portion 14b and cored wire 14a in lead 14 with covering portion 14b and cored wire 14a, thus, and the 1st
Positioning element 17 keeps covering portion 14b and cored wire 14a.Because the 1st positioning element 17 has heat-shrinkable, therefore, determine by the 1st
Position part 17 is mounted across after the covering portion 14b and cored wire 14a of lead 14 state, can be easily by shrinking
1st positioning element 17 is fixed on lead 14.Therefore, in assembling procedure of Lighthead assembly 13 etc., the energy of the 1st positioning element 17
Enough suppress Lighthead assembly 13 and produce dislocation in the longitudinal direction relative to lead 14.2nd positioning element 18 is with adjacent with through hole 13c
The mode connect is arranged on the outside of Lighthead assembly 13, and it keeps the covering portion 14b of lead 14.
(positioning action and insulating effect based on the 1st positioning element and the 2nd positioning element)
As shown in Fig. 2 in the cylindrical portion 13a of Lighthead assembly 13 inside, the 1st positioning element 17 with Lighthead assembly 13
The end of through hole 13c adjoinings is contacted with end face portion 13b, thus, covering portion 14b the passing through relative to Lighthead assembly 13 of lead 14
Perforation 13c is positioned.Therefore, the relative position between through hole 13c and cored wire 14a can be made by the 1st positioning element 17
Accurately positioned, therefore appropriate dielectric breakdown strength can be stably obtained in the outside of Lighthead assembly 13.Also, it is logical
There is deviation in the relative position that crossing the 1st positioning element 17 can suppress between Lighthead assembly 13 and lead 14, so as to suppress
There is deviation relative to the relative position of sealing 11 in Lighthead assembly 13, therefore, it is possible to stably obtain Lighthead assembly 13 relative to
The appropriate adhesive strength of sealing 11.
In the same manner, in the outside of Lighthead assembly 13, the through hole 13c adjoinings with Lighthead assembly 13 of the 2nd positioning element 18
End contacted with end face portion 13b, thus, the covering portion 14b of lead 14 is determined relative to the through hole 13c of Lighthead assembly 13
Position.Therefore, there is deviation in the relative position that can be suppressed between Lighthead assembly 13 and lead 14 by the 2nd positioning element 18, because
And it is able to ensure that appropriate insulating properties so that it is strong stably to obtain appropriate insulation breakdown in the outside of Lighthead assembly 13
Degree.Also, there is deviation in the relative position that can be suppressed between Lighthead assembly 13 and lead 14 by the 2nd positioning element 18, from
And Lighthead assembly 13 can be suppressed and deviation occur relative to the relative position of sealing 11, therefore, it is possible to stably obtain lamp head
Appropriate adhesive strength of the part 13 relative to sealing 11.

The cored wire 14 exposed in covering portion 14b welds together, so as to form connecting wire 12 and cored wire 14a connecting portion 16.It will draw
Line 14 passes through the 1st positioning element 17, and by the 1st positioning element 17 installed in the cored wire 14a and cladding near connecting portion 16
On portion 14b position.Then, the 1st positioning element 17 is heated so that its thermal contraction, so that the 1st positioning element 17 be consolidated
It is scheduled on the assigned position on the length direction of lead 14.
Next, lead 14 to be passed through to the through hole 13c of Lighthead assembly 13, and Lighthead assembly 13 is arranged on its end face portion
The position that 13b inner side is in contact with the 1st positioning element 17.Afterwards, lead 14 is passed through into the 2nd positioning element 18, and the 2nd is determined
Position part 18 is arranged on the position with being in contact on the outside of the end face portion 13b of Lighthead assembly 13.Next, to the 2nd positioning element
18 are heated so that its thermal contraction, so that the 2nd positioning element 18 to be fixed on to the assigned position on the length direction of lead 14.
Thus, by the 1st positioning element 17 and the 2nd positioning element 18 that are fixed on lead 14, it can be precisely located
Relative position of the Lighthead assembly 13 relative to lead 14 and sealing 11.Finally, filled into the cylindrical portion 13a of Lighthead assembly 13
Bonding agent 15, and solidify bonding agent 15, so that Lighthead assembly 13 is fixed on the sealing 11 of luminous tube 6.In this way, by lamp holder
Part 13 is assembled on sealing 11.

Part 18 is arranged to the through hole 13c adjoinings with Lighthead assembly 13.Thus, the 1st positioning element 17 and the energy of the 2nd positioning element 18 are passed through
Lighthead assembly 13 is enough set to be positioned relative to lead 14, therefore in the axial direction of luminous tube 6, it is possible to increase Lighthead assembly 13 and lead
The positioning precision of relative position between 14.As a result, according to ultraviolet lamp 5, the insulation in the outside of Lighthead assembly 13 can be suppressed
Breakdown strength and the adhesive strength of Lighthead assembly 13 decline, so as to ensure appropriate dielectric breakdown strength and Lighthead assembly
13 adhesive strength.
In addition, the 1st positioning element 17 that the ultraviolet lamp 5 of embodiment has is arranged on the inner side of Lighthead assembly 13,
And the 1st positioning element 17 keeps the cored wire 14a and covering portion 14b of lead 14.For example, by receiving the heat of the 1st positioning element 17
Contracting, can make the 1st positioning element 17 in the inner side of Lighthead assembly 13 to keep drawing across the state in cored wire 14a and covering portion 14b
Line 14, thus, the stationary state of the 1st positioning element 17 become stable, it is possible to increase length of the 1st positioning element 17 in lead 14
Positioning precision on direction.
Also, the insulation for the 1st positioning element 17 and the 2nd positioning element 18 that the ultraviolet lamp 5 of embodiment has
Breakdown strength is more than 3kV/mm.Thereby, it is possible to rightly ensure the dielectric breakdown strength in the outside of Lighthead assembly 13, accordingly, it is capable to
Enough suppress Lighthead assembly 13 and occur short circuit etc..
Also, the ultraviolet lamp 5 of embodiment have configuration the inner side of Lighthead assembly 13 the 1st positioning element 17 and
Configure the 2nd positioning element 18 in the outside of Lighthead assembly 13.Thus, Lighthead assembly 13 is positioned by the 1st positioning element the 17 and the 2nd
Part 18 is clamped and positioned, therefore, it is possible to further improve positioning accurate of the Lighthead assembly 13 on the length direction of lead 14
Degree.
